The colonel, later general Hans Philip Fuchs von Bimbach (ca. 1567–1626) was for some years the most influential official at the court of the Protestant Margrave Joachim Ernst of Brandenburg-Ansbach and was engaged as a diplomat beyond the state’s borders. However, later he fell out with the Margrave and entered into imperial (i.e., Catholic) service. He changed sides again and finally fell at the Battle of Lutter in the service of the Danish crown. Fuchs von Bimbach informed Simon Marius about the invention of the telescope already in the autumn of 1608 and as patron helped him to obtain one of the first copies. Thus, he seems to have played a considerable role in the early history of the telescope. This article gives biographical data about Fuchs von Bimbach. It attempts to define more precisely his role in the first astronomical applications of the telescope and also presents new insights into Simon Marius’s work.

Introduction

The name of his sponsor Fuchs von Bimbach zu Möhren arises several times in the literature about Simon Marius, without mentioning his biographical dates and without examining the relationship between this general and politician and Simon Marius. Certainly, without his help Marius would only have received and used a telescope much later—maybe even not at all—and may have been in the history of astronomy just one of many calendar makers; additionally, this concerns one of the earliest ever mentions of telescopes, only weeks or months after its invention.

Who was this man with the exceptional name? Which business had a military man and politician at the Frankfurt fair, where he saw one of the first telescopes in 1608? What is secure knowledge about Simon Marius, Fuchs von Bimbach, and the telescope and what is only speculation? The present study undertakes an initial examination of these questions.

A scientific biography of Hans Philip Fuchs von Bimbach using archival sources is still a desideration of research; this is also desirable for a biography of Marius. For general reasons I could use only secondary literature and couldn’t consult all relevant publications for the present study. Using new or previously unused literature gives, nevertheless, a more comprehensive picture of Marius’s sponsor, compared to previous biographies. Some incorrect statements about Fuchs von Bimbach and Simon Marius that were perpetuated in popular as well as in scientific literature are debunked (see section “Errors and Speculations about Fuchs von Bimbach in the Literature”). Yet I can’t verify that all biographic dates mentioned in the other sections are correct. Much of the following information should in general be treated with caution, as they originate from particularly unreliable sources. The review with original sources, as far as this is possible, remains a task for future historians.

The following description is more detailed in terms of family origins and the early years of his life, because there has been almost no information in Fuchs’s biographies until now. There is a lot of material about the Ansbach years and the later period that can only be bundled together for a brief characterization. The main focus is on the cooperation with Simon Marius. Concerning this, all known facts will be named and reinterpreted. The final section outlines approaches for further research.

Biographical Data About Hans Philip Fuchs von Bimbach

The Fuchs von Bimbach Family

The family of the Fuchs von Bimbach with the manor Bimbach belonged to several cantons of the Franconian Ritterkreis (Knight’s Company), especially to the canton Baunach from the end of the tenth century until 1806 (Köbler 1999, p. 184).Footnote 1 Several other families named Fuchs existed until the seventeenth and eighteenth centuries in Franconia (e.g., Fuchs von Dornheim, von Neidenfels, and von Wiesentheid). Almost all of them died out (Tittmann 1998).Footnote 2 The Fuchs von Bimbach belonged in the seventeenth century to the lower or middle untitled Franconian nobility. In 1699 they were awarded the title baron (“Freiherr”) (Fuchs von Bimbach 1975; B[ressensdorf] 1988). It is significant that the Franconian Fuchses, among them the Fuchs von Bimbach, held the rank of Franconian Reichsritter (imperial knights) and so were subordinated only to the emperor, not to the sovereigns. Nevertheless there were tight-woven, partly symbiotic bonds to fiefdoms, patronates, and court employments but also conflicts resulting from struggles for independence from the liege lords.

Founding father of the family Fuchs von Bimbach was the Franconian nobleman Dietrich Fuchs who bought Bimbach in 1404. The local castle, destroyed during the German Peasants’ Revolt and later rebuilt, was in the family’s possession until 1913. The little town Bimbach belongs to Prichsenstadt (county of Kitzingen) in Unterfranken (Lower Franconia) since 1972.Footnote 3 The Fuchs we are interested in had little to do with Bimbach.Footnote 4 In his lifetime five family lines of the Fuchs von Bimbach existed. They were differentiated by their family seats. One of them resided in Bimbach, the others in Burgpreppach, Gleisenau, Eltmann, Bischofsheim, and Möhren.Footnote 5

Hans Philip’s great uncle Dietrich as the eldest son received the dominion Bimbach and founded the line Fuchs von Bimbach-Bimbach. His younger brother Christoph, grandfather of Hans Philip, purchased the castle of Mehren (later written Möhren) in the Duchy of Palatinate-Neuburg in 1522. Christoph’s sons Endres and Sigmund called themselves from 1545 on Fuchs von Bimbach zu Mehren (= Möhren) or Fuchs von Bimbach-Möhren (Tittmann 1998, p. 79, note 385). The community of Möhren is a part of Treuchtlingen (county of Weißenburg-Gunzenhausen) in Mittelfranken (Middle Franconia) since 1972,Footnote 6 while Neuburg today belongs to the Bavarian administrative district of Oberbayern (Upper Bavaria). That Möhren belonged to Palatinate-Neuburg, at that time, was a decisive factor for the life of Hans Philip Fuchs von Bimbach.

The male line of the Fuchs von Bimbach has expired today but the name is continued in the female line.Footnote 7 The present seat of the Fuchs von Bimbach is the castle of Burgpreppach, where the family archives is also stored.

After the reformation most family members probably became Protestants, though Hans Philip’s uncle Hans Fuchs von Bimbach (b. 1562) was a Catholic clergyman, Domkapitular (canon) in Bamberg and Würzburg (Biedermann 1747, Tabvla LIX). For Hans Philip no special faith preferences are known; he served on the Protestant side as well as the Catholic. His nephew, last of the Bimbach-Möhren line, converted to Catholicism to take possession of his heritage with the Emperor’s help. Today the family Fuchs von Bimbach und Dornheim is Catholic (Fuchs von Bimbach 1975).

Family, Birth, and Youth in Palatinate-Neuburg

His father Endres (ca. 1519–1599)Footnote 8 is believed to have already come to the court of Palatinate-Neuburg in 1537 (Ludwig 1968, p. 42) then under Otto Henry, Elector Palatine (Ottheinrich von der Pfalz), from 1557 on under Wolfgang of Palatinate-Zweibrücken. In 1556 he became Landrichter (state judge) of Grailsbach and Pfleger (governor) of Monheim and in 1561 Statthalter (governor) of Neuburg/Donau.Footnote 9 After Wolfgang’s death in 1569, the Duchy of Palatinate-Neuburg was separated and became independent under the new duke Philip Ludwig. As a governor Endres was some kind of representative in his absence and consultant of the sovereign; besides he was chief of protocol when foreign nobleman had to be welcomed. He also conducted negotiations, e.g., about marital contracts. His activities as a diplomat, administrator, and judge are documented in detail (Schöndorf 2006). His biographer writes about his “gradlinigen, etwas raubeinig wirkenden Art” (“straight, somewhat roughnecked character”) and describes his efforts to increase and protect his possessions.

In 1546 Endres married Margaretha von Seckendorff-Aberdar who died in 1564; the marriage remained childless.Footnote 10 His mother-in-law, also Margaretha, was his cousin and was brought up in his father’s household.Footnote 11 On November 28 or December 8 or 18, 1566, he re-married to Anna von Zeiskam (Zaiskam) from the Electoral Palatinate, the daughter of another governor of Wolfgang of Palatinate-Zweibrücken.Footnote 12 It would be interesting to know the exact date for the earliest date of birth of the eldest child, as it has to be excluded that Endres and Margaretha had “in Unehren zusammengekrochen” (“dishonorably crept together”), as the pastor of Bimbach would have called such cases.Footnote 13 In this marriage eight sons and two daughters were born. Four survived, Hans Philip, Lud[e]wig Veit, [Hans] Carl, and Anna Maria.Footnote 14 Without proof Hans Philip is considered to be the eldest, but I doubt this (see below).Footnote 15

His brother Ludwig Veit served as a Hofmeister (court tutor/master of ceremonies) in Palatinate-Neuburg. He seems to be the only brother who had children, Hans Carl and Anna Maria.Footnote 16 Ludwig Veit died accidently in 1607,Footnote 17 and his brother Carl fell in Hungary in a battle against the Turks in 1604.Footnote 18

The first names of the son, who interests us, are written very variably in the literature: Hans/Han[n]ß/Johan[nes] Philip[p][s], latinized Iohannes Philippus (by Marius; Marius 1614/1988, p. 36) or Iohan Philip (in the cartridge of his portrait; see Fig. 3.4). Even finding the baptismal register wouldn’t give clarification about the “correct” spelling, as there were no fixed orthographical rules for names at those times. I presume that today’s widespread notation “Johann Philipp” results from the assumption (in admissible analogy to modern use) that Hans could only be a modified version of the baptismal name Johann. Hans (in different spellings) instead of Johann obviously was the contemporary form, for Fuchs von Bimbach, as well as for other persons. The parish register of Bimbach from 1576 to 1588 (Schmidt/Müller 2001), for example, lists in the entries of marriages and baptisms only “Hans” as first name of several persons in various spellings (occasional three spellings for one and the same man), but I couldn’t find a “Johann.” The introduction to Marius’s translation of Euclid he signed “Hanß Philips Fuchs von Bimbach” (Marius 1610, sig. A4v); a letter written short before his death he signed “Hannß Philip Fuchsen” (Lichtenstein 1850, p. 145); also the nobleman today known as Johann Ernst von Anhalt he called “Hanß Ernst” (see below), which indicates his own use of Hans instead of Johann. Also other representatives of the family before and after him were called Hans; a Johann can be found only in the eighteenth century ([Gotha] 1924, p. 253). So I decided to use “Hans” instead of “Johann” and to write both first names in their shortest form, though “Philipp” would be as correct as the today unknown “Philips” or a spelling of Hans in other, today unusual forms.

Nothing is known directly until now about the birth of Hans Philip; conclusions can only be drawn from other data. If he really was the eldest son, as it is assumed, he could have been born in the second half of 1667, however not earlier, as second eldest son in 1668 but not much later.Footnote 19 The most likely birthplaces are Möhren or Neuburg.

In 1580 Hans Philip is verifiable in the Fürstliche Schule (Princely School) in Lauingen, where he held two reported speaches as a student; the school’s historian assumes a stay from at least 1579 to 1583 (Ludwig 1968, p. 42).

The next biographical date given in the literature is a stay in Padua in October 1587 at the age of not more than 20.Footnote 20 It has been concluded that Fuchs studied there from this date alone. But he is not included in the registers of the German Nation in Padua,Footnote 21 so studies there seem very unlikely. There’s nothing known about possible university studies until now; all information concerning this are nothing but speculations. From his further work and from his and Marius’s writings, we can only conclude that he had extensive military experiences and some knowledge of military history, which he also recorded in writing (see section “Fuchs von Bimbach as a Military Author”). He had acquired at least basic skills in optics (see section “Fuchs, Marius and the Telescope”) and concerned himself with geometry and its applications (see section “The Translation of Euclid”).

The stay in Padua may have been during a “Kavalierstour” (educational tour), as was usual for young noblemen (often after finishing their university studies). About 100 years later, this is documented in detail for some of his relatives (Rößner 2003; Flurschütz da Cruz 2014, Sect. 1.3.1). There are indications that he might have stayed in Lyon in his younger years (Zwanziger 1919, p. 24).

Certain conclusions about his education might possibly be drawn by considering the education of 16-year-old Ludwig Reinhold Fuchs von Bimbach in 1682, who was expected to follow his famous relative Hans Philip in his military career (cf. section “Attempt to Assess of Hans Philip Fuchs von Bimbach”). His godfather recommended his mother that the son “eine gute Wißenschafft, in der Rechen=, Meß=, Kriegs= und Friedens=Bau=Kunst, auch etwa eine Verständnüß in Ernst= und Lust=Feüern, dann in der Geographie bey zubringen wäre.”Footnote 22 “Die frantzösische Sprache, Reiten, Fechten und Tantzen”Footnote 23 would also be important. Ludwig Reinhold was sent to the University of Tübingen and afterward to France.

From his own records, it is clear that Fuchs von Bimbach had been taken part in military campaigns since the 1580s (Jähns 1890, p. 922; cf. section “Fuchs von Bimbach as a Military Author”). If he was born in 1567/1568, he would have been 17–18 years old in 1585.

In 1596 he became Hauptmann (captain) of Neuburg and was assigned to bring the contingent of the Protestant estates to the war against the Turks in Hungary.Footnote 24

In 1599 Hans Philip inherited together with his two brothers the property Möhren and the family properties near Gerolzhofen (Buchner/Mavridis 2009). His brother Ludwig Veit became Lord of Möhren.Footnote 25 So one could assume that Ludwig Veit was the older brother and Hans Philip’s year of birth would be 1568 at the earliest.Footnote 26 Possibly he added “auf Möhren” to his name only after his brother’s death; that means from 1607/1608 on.

His father’s inheritance was obviously not insignificant. For example, in 1582 Endres bought several properties and rights in Sulzfeld and five other places for 3700 guilders; in 1594 he sold the castle Rauenbuch that he had inherited from his mother-in-law with all belongings and rights to Margrave Georg Friedrich of Brandenburg-Ansbach and Bayreuth for 16,000 guilders (Rechter 1997, p. 112 and 125).

The connections of the family to their liege lord, the Duke of Palatinate-Neuburg, seemed to have been close. For example, in a chronicle of Möhren, the following is reported in connection with the death of Carl in Hungary in 1604: “Seine beiden Brüder feierten seine Leichengottesdienste dahier, und luden zu dieser Feier den Herzog Philipp Ludwig von Neuburg ein, welcher in höchster Pracht in Person erschien, und den Leichengottesdiensten beiwohnte.”Footnote 27 About 1601 Hans Philip quit the service in Palatinate-Neuburg but stayed connected to the dukes there, partly because of the fief Möhren but certainly also through a, then usual, patronage.

Nothing is known about a marriage or a family of his own. After his brother’s, Ludwig Veit’s, death, he became guardian of his son Carl.Footnote 28 Later this nephew succeeded him. As Hans Carl died in 1662, the family line Fuchs von Bimbach-Möhren expired.

Serving the Brandenburg Margraves in Ansbach

In 1599 Hans Philip led Ansbach troops in the so-called Straßburger Fehde (Strasbourg Feud). This started his career at the Ansbach court.Footnote 29 Whether he had already entered this service in that year or was just “lent out” from Palatinate-Neuburg for this military campaign has still to be investigated. Generally, all of his military service was interim, as was then usual. In 1601/1602 Fuchs von Bimbach fought again in the “Long Turkish War” (1593–1606) (Veh 1984–1985, p. 146) in which his brother would fall 3 years later. Later he remembered one episode where “wir selbsten anno 1601 vor Wienn vnd Preßburg, da wir des Obersten Fürsten Hanß Ernst von Anhalt Oberstlieutenant gewesen, gesehen.”Footnote 30

Also in 1601 he became Kriegsrat (military advisor) to Margrave Georg Friedrich. One year later he joined the Spanish-Dutch war as some kind of custodian for the margrave’s 19-year-old relative and designated successor, Joachim Ernst, which led to a close relationship between them.

Joachim Ernst inherited the Margravate of Ansbach in 1603. In the fall of this year, he gave Schwaning and Rechenberg to Fuchs von Bimbach and his brothers as fiefs to very favorable conditions. Fuchs von Bimbach immediately started to build his own castle in Schwaning, today’s Unterschwaningen in the Middle Franconian administrative district of Ansbach, halfway between Ansbach and Möhren.Footnote 31 From 1604 to 1606, he dwelled in the Netherlands again with the young Margrave, from 1605 on as an “Obrist” (colonel). At the inducement of Joachim Ernst, he assembled a battalion of soldiers for the Dutch States General.Footnote 32

Simon Marius called Fuchs von Bimbach in 1614 “a man of the highest celebrity, not only for his ancient and noble lineage, but also and chiefly for his great deeds, his heroic exploits, and his consummate skill in war throughout France, Hungary, Belgium, and Germany.”Footnote 33 “France” could mean the Strasbourg feud; “Belgium” was the name for the Netherlands at that time.

After his return from the Netherlands, his short political career at the Ansbach court began. From 1607 to 1610, Fuchs von Bimbach was the director of the Geheimer Rat (Privy Council), as well as of the Hof- und Kammerrat (Court and Chamber Council). He was the most powerful court official and highly paid.Footnote 34 He also worked outside the margravate, e.g., through participation in the founding of the Protestant Union in 1608, and was often underway in diplomatic missions across the Empire, e.g., in Frankfurt am Main.

From 1610 on Fuchs withdraw bit by bit from the Ansbach court. This was related to quarrels between him, other court officials, and also later the Margrave. First he quit his position as director of the Court and Chamber Council but continued leading the conferences of the Privy Council (Herold 1973, p. 209). His full income was paid until 1614.

In 1610 the building of his castle was almost finished but he seems not to have retired to his estates. Instead he became an artillery general in the Jülich-Klevische Erbfolgestreit (War of the Jülich Succession, an inheritance dispute). This was in the interest of his Palatinate-Neuburg liege lord Philip Ludwig, who was supported by the dukes of the Protestant Union (Jähns 1890, p. 922).

In 1616 the break with Margrave Joachim Ernst was definitive when Fuchs von Bimbach approached the Catholic side. There were also financial claims by Fuchs, who started litigation at the Reichskammergericht (Imperial Superior Court of Justice) against Joachim Ernst, as well as other conflicts (Zwanziger 1919, p. 27; Herold 1973, p. 46 and pp. 209–212).

It might have been an unfavorable coincidence for Simon Marius that his Mundus Iovialis, in which he praised Fuchs von Bimbach, was published just when Fuchs’s conflicts with the Ansbach court escalated. Nothing is known about tangible impacts on Marius, but he complained about intrigues to his detriment just at that time.Footnote 35

Fuchs von Bimbach as a Military Author

The state library of Württemberg holds a handwritten military tract, whose author is not mentioned, but who is obviously Fuchs von Bimbach.Footnote 36 This manuscript also includes autobiographical notes. It was written at the earliest in 1610, military historian Jähns assumed it originates from around 1612.

After a short historical introduction, the essay expands on many organizational grievances in the military, based on the author’s own experiences, e.g., as the following:

Unter Kaiser RudolfFootnote 37 habe man geradezu die jungen unerfahrenen Herren, zumal wenn es hohe Standespersonen gewesen, den erfahrenen Obersten grundsätzlich vorgezogen, weil sie sich mit geringer Besoldung begnügt und den oft fehlerhaften Anweisungen aus Wien nicht widersprochen hätten.Footnote 38

As an evil custom of the foot soldiers he reprimanded “das Mitschleppen eines übermäßig großen Weibertrosses” (“that they dragged an abundantly large train of women”) but admitted:

Wiewol die Teutschen weiber den Soldaten beuorab in Ungarn mit tragender notturfft sowohl in wartung in kranckheiten denen Soldaten sehr nützlich sein. Zum tragen findet man selten eine, die vnder 50 oder 60 Pfund tregt; da etwan der Soldat mit Victualien oder ander dergleichen tragende wahren nit versehen, so ladet er ihr Stroh oder Holz daruor auf, zu geschweigen, daß manche ein, zwei oder mehr Kinder uf dem Ruckhen tregt.Footnote 39

Then he listed in detail the clothing and tableware that a woman carried for a man along with their tent.

After this introduction the following three chapters primarily apply to the training of soldiers, especially the infantry (in today’s parlance) with a lot of drawings. Chapter II presents for the most part a “in ganz unwesentlichen Punkten geänderte Abschrift der ‘Instruction’ des Landgrafen Moriz von Hessen v. J. 1600, die jedoch nicht genannt wird.” “Das IV. Kapitel gibt einen kurzen Abriß der Feuerwerkerei ohne besonderen Wert.”Footnote 40

Jähns discussed the unpublished work of Fuchs von Bimbach within the framework of Geschichte der Wissenschaften in Deutschland (“History of science in Germany”—a history of astronomy by Rudolf Wolf was also published in this series). One can’t refer to this work as “scientific” in the narrow sense whereby the general level of military lore at that time must be taken into consideration. It contains a lot of empirical findings as well as pragmatic conclusions and might have been intended as an instructional and textbook.

It is remarkable that Fuchs von Bimbach probably worked on his book during the same years in which Simon Marius wrote Mundus Iovialis. Did they perhaps inspire each other to compose a longer publication?

In the Thirty Years’ War

From the following years until Fuchs’s death, no more contacts to Simon Marius are known. Therefore this period of time will be handled very briefly, though a lot of material exists.Footnote 41

Fuchs von Bimbach entered imperial service after lengthy negotiations in 1618. As a reason for his change of station, Johann Ernst’s biographer cites the insults at the Ansbach court, from which Fuchs suffered as an imperial knight (Herold 1973, p. 46). As background it has to be taken into consideration that his new Palatinate-Neuburg liege lord and patron, Wolfgang Wilhelm, had converted to the Catholic Church in 1614, shortly before his father’s death and against his will. In particular he hoped for the Emperor’s support in the War of the Jülich Succession. Thirdly, as an imperial knight, Fuchs was formally only subordinated to the emperor, so serving him was normal rather than scurrilous. Confessional concerns seem unimportant to him. And finally he was principally an officer and therefore always on search for new appointments.

Emperor Matthias appointed Fuchs von Bimbach on July 7, 1618, to his “Obristen, Hofkriegsrat und Obristfeldzeugmeister” (colonel, court councilor of war and colonel gun master).Footnote 42 (“Feldzeugmeister,” literally “battlefield ordnance master,” was the name of the artillery officers; they were subordinated to a colonel.Footnote 43) It is disputed whether he was involved in the Battle of White Mountain in 1620. Afterward he was accused that, as commander of the artillery, he had willfully ordered too short bombardments and was discharged without full payment (Zwanziger 1919, p. 27). So he also had to put up with an insult in imperial service.

From 1621 on we find him again on the Protestant side as an officer and diplomat. The relationship to his (meanwhile Catholic) liege lord Wolfgang Wilhelm of Palatinate-Neuburg however remained very close. The latter lobbied for him against the Emperor for Fuchs’s dominion Möhren and assigned to him the mediation between Emperor Ferdinand II and the Danish king Christian IV , which remained unsuccessful. In 1625 Fuchs was urged by Christian IV to join his service as an infantry general and later artillery general (Lichtenstein 1850, p. 143), which resulted in a condemnation by Ferdinand II and a threat to confiscate his estates.

Like other officers, Fuchs had deposited his most valuable movable possessions at the company of Samuel Rademacher in Hamburg during the war (Zwanziger 1920, p. 15).

Death in the Battle of Lutter

On August 27, 1626 (on the Julian calendar, this was August 17), one of the biggest and most momentous battles of the Thirty Years’ War took place on a plane west of the Harz and south of Salzgitter near the village Lutter am Barenberge (Fig. 3.1). Instead of defeating the troops of Tilly and Wallenstein, as intended, the Danish king suffered a disastrous defeat. The battle finally ruined his imperial aspirations and after the war he possessed less than before. Fuchs von Bimbach, the highest ranking officer next to the King, is said to have warned him about entering the battle.

Whether the following description of Fuchs von Bimbach’s death is authentic or was elaborated later has still to be researched:

Groß und stark beleibt war ihm an dem heißen Schlachttage die Rüstung zu unbequem, er trug dafür eine weiße seidene Aermelweste (Wamms) und über diese einen kurzen leichten Oberrock (Casake) von grauer Farbe, so daß die hohe Figur überall leicht zu erkennen war. Verwundet nahm er, der anfänglich von einigen Ligisten für den König gehalten, den ihm angebotenen Pardon nicht an und wurde, von noch mehren Streichen tödtlich getroffen noch lebend nach Nauen in des Königs gewesenes Quartier, den riemschneiderschen Hof gebracht und auf die Bank hinter den Ofen niedergelegt. Er befahl hier, ihn an der Stelle, wo er gefallen, zu begraben, auch sein Grab zu respectieren und starb dann.Footnote 44

So Hans Philip Fuchs von Bimbach died on August 27, 1626 in the small village Nauen near Lutter at the most 59 years old. Today two memorial stones stand on a parking area near to his former grave (Fig. 3.2). The oldest dates from 1908 (Melzner 1982). The Fuchs von Bimbach family paid an annual amount to the owner of the field to maintain the grave until the end of the eighteenth century. Around 1800 a road from Lutter to Seesen was built, today’s B 148. The ditch went through Fuchs von Bimbach’s grave, which was opened. It contained a remarkable tall skeleton and a valuable sword (Lichtenstein 1850, pp. 143–144). To the facts about the grave and the memorial stones, more exact researches are desirable because the dates in literature and in the Internet are inaccurate, contradictory, and partially grossly incorrect.

In passing it is noted that before the Battle of Lutter, a nightly luminous effect was reported in the form of a sword that pointed from the imperial to the Danish troops and inspired the former to fight. This could be interesting for astronomers and meteorologists who deal with reports about noctilucent clouds and similar phenomenon. However, it can’t be excluded that this was only a rumor put into the world by Tilly as psychological warfare (Lichtenstein 1850, pp. 134–135).

Fuchs’s Financial Circumstances

Through inheritance and purchase in the form of fiefs, Fuchs von Bimbach owned several estates and castles. Besides the main property of Möhren, this included the large, richly endowed castle Schwaningen (Fig. 3.3), Rechenberg manor, and the castle of Cronheim near Gunzenhausen. From these he received income from the farms and payment in kind such as fish, wood, and the hunt bag.

After his departure from Ansbach, he was criticized for not having paid for the fiefdom of Schwaningen and through abuse of office to have used margravial material and workers for the building of the castle (Veh 1984–1985, p. 148 and pp. 151–152). The truth of these accusations might be difficult to verify.

The worth of the fiefdoms can be assessed by the amount the widowed Margravine Sophie paid in 1630 to the heir Hans Carl Fuchs von Bimbach for the return of Schwaningen and Rechenberg, namely, more than 75,000 guilders (Veh 1984–1985, p. 153).

His annual income in Ansbach was 2581 guilders, additionally a large payment in kind of wine, cereals, and fish (Herold 1973, p. 46, note 66). In 1612 he lent the margrave 20,000 guilders for his marriage. For repayment Joachim Ernst used all the incoming taxes (Herold 1973, p. 191). His income in earlier and later assignments, as an officer, has not yet been determined.

The inheritance deposited in Hamburg included cash, silverware, precious clothing, jeweled harnesses, canons, horses, and other things amounting to 10,000 thalers (= 240,000 guilders).Footnote 45

To roughly estimate these amounts in today’s currency, we set Marius’s annual payment of 150 guildersFootnote 46 as today equal to 10.000 € as a lower limit. We receive for the value of both fiefdoms not less than five million euros, for Fuchs’s annual pay about 170,000 €, for the credit to the Margrave 1.3 million euros, and for his disposable inheritance 16 million euros.

Fuchs’s Physical Appearance

We are mostly informed about Hans Philip Fuchs von Bimbach’s appearance by his portrait (Fig. 3.4). A comparison to the portrait of Simon Marius from about 1614 (see Fig. 5.2) shows a great similarity stemming from the beard style, the haircut, and the clothing, whereby Fuchs’s one is of course more splendid. Portraits of other contemporaries (see Chap. 2) show less similarities. It remains speculation as to whether Marius adapted his appearance to match his patron.

(b) Portrait of Fuchs von Bimbach in a later, corrected version. Source: Staatsbibliothek Berlin—Preußischer Kulturbesitz (see footnote 49). (c, d) Details of the Portraits (a, b)

Fuchs is described as “groß und stark beleibt” (tall and corpulent); later an “auffallend große[s] Skelett” (remarkable tall skeleton) was found in his grave (Lichtenstein 1850, p. 143 and 144). In his inheritance in Hamburg was “eine Stadtliche, fürstliche, ja Königl. Kleidung” (splendid, princely, even royal clothing; quoted after Zwanziger 1920, p. 15), so he attached value to a representative appearance.

The eye patch seen in the portrait indicates a severe injury or even the loss of his right eye, maybe in the battle, but I couldn’t find anything about that.Footnote 47 He has a vertical scar across his right eye, apparently from a sword strike. If the portrait was painted posthumously, it could be a wound from one of the last battles before his death.

The form of his eye patch obviously results from artistic freedom of expression; an earlier version (or draft?)Footnote 48 shows the patch bigger and rectangular (Fig. 3.4a, c); the final versionFootnote 49 shows it smaller and semicircular (Fig. 3.4b, d).Footnote 50 The first version shows clearer that it could be a provisional covering of the wound with a piece of cloth that was attached to a string around his head and fixed with a second string on top of the cloth. For a permanent eye patch after the loss of an eye, I would expect another material (leather), another form, and a more comfortable fitting, but only a medical historian could give more precise information about that. One can at least assume that he wore this eye cover only at the end of his life. The engraving was made around 1626, maybe only posthumously, as the signature shows, but possibly also from an earlier template.

Fuchs von Bimbach as Sponsor of Simon Marius

Introduction

All that I have observed, developed and already published in this regard, I owe to this great and most noble gentleman, my protector and patron, who holds all my reverence.Footnote 51

The Latin word Marius uses here, translated as “protector,” is “Patron”—again we come across patronat, very usual in those times. Protection and sponsoring by Fuchs von Bimbach, who was the highest official in the margravate with significant influence on the margrave, made him at least temporarily feel more secure. Contrary to Kepler, who found patrons in Rudolf II and later Wallenstein only for short periods, Marius was secured by the patronage of the Ansbach margraves in a long term, and so he was more or less independent of his second protector Fuchs von Bimbach.

John Robert Christianson assumed that Marius did not hurry to publish his discoveries due to his secure position, differing from Galileo who was looking for a good position.Footnote 52 This could have been a reason but just one among others such as uncertainty as discoverer, inexperience with respect to priority claims, relative isolation from other scientists, lack of time because of his calendar production, health problems, etc.

The most important events in the relationship between Simon Marius and Fuchs were the acquisition and use of early telescopes. For the history of their invention, Marius’s report about Fuchs’s visit to the Frankfurt fair in 1608 is very important because this seems to be one of the earliest recorded dates that we have. The first exact date is September 25, 1608 (Gregorian).Footnote 53 It would be desirable to narrow the time span of Fuchs’s visit in Frankfurt am Main, as the question of which of the three Dutch inventors could have been to Frankfurt depends on this.Footnote 54 Besides the general question arises (though irrelevant to the telescope), why an officer and politician visited a trade fair. Therefore in the following section, general remarks about trade fairs of the period and about Fuchs’s visit at the fair of 1608 will be made before we focus on the description given by Marius. Finally we will discuss the cooperation of Marius and Fuchs on a translation of Euclid’s writings that was published in 1610.

Possibly Fuchs von Bimbach came closer to Marius only during the telescope episode in 1608 though he must have known him and his calendars earlier. (Contrary to Wallenstein, nothing is known about any interest in astrology that Fuchs might have had.) Unfortunately, we know nothing at all about their relationship before the fall of 1608 and after 1612. Marius’s statement that Fuchs “… frequently talked the matter over with me after supper” (see below) indicates that Marius was invited to supper several times and their relationship must have been quite close at least in the fall of 1608. For the year 1612, Fuchs’s assistance to Marius is documented.Footnote 55 Hans Gaab assumes in his chapter (section “Life at Court and Publications” in Chap. 2) that the problems Marius had in Ansbach were somehow related to his good relationship to the unpopular Fuchs von Bimbach.

The Visit of the Frankfurt Fair in 1608

At that time, the Frankfurt Reichsmessen (Imperial fairs) were not only important economic events but also top-ranking social occasions (Stahl 1991; Brübach 1994). They served trade among merchants as well as the retail sector. What was lacking at ordinary markets could be found here, e.g., gems and books (also antiquarian). It was a place for settlements (often cashless but also with cash) and a financial center for exchange, credits, and investments. As many people met there, the fairs were also used for the exchange of information, not only between the merchants, and also for entertainment; there were theater productions, jugglers performed, and exotic animals were displayed (e.g., an elephant in 1629) or just pictures. Besides, tolerated by the councilmen, prostitution flourished, with which the local women would be protected from the many strangers. The fair replaced that which is matter of course for us today: shopping centers, banks, newspapers, television, theater, varieté, circus, and so on. Noblemen loved to visit the fair to meet their peers, to shop, or to just be entertained.

Fuchs von Bimbach had been to Frankfurt on other occasions. Marius’s report about a merchant “whose acquaintance he [Fuchs] had formerly made” suggests that Fuchs had also visited the trade fair in earlier years (Marius 1614/1916/2019, Preface). He might not only have had private motives (shopping, investment) but also business reasons such as purchasing for the Ansbach court together with other officials,Footnote 56 negotiating credits for the margrave, repaying his debts, and meeting other noblemen for diplomatic conversation. It might well be that he and other armed travelers guarded money or goods transports between Ansbach and Frankfurt.

When did the trade fair take place in 1608? For this there are earlier considerations in the literature about the history of the telescope, without taking all circumstances into consideration. A detailed history of the Frankfurt trade fair from 1765, evaluated by Albert van Helden (1977, pp. 21–22), reports that originally the trade fair took place between Assumption Day (August 15) and the Nativity of Mary (September 8). Already in the sixteenth century, its start had switched to the Nativity of Mary.Footnote 57

To that another tradition must be considered; if the Nativity of Mary fell on Monday, Tuesday, or Wednesday, the trade fair started on Monday; if the holiday fell on Thursday, Friday, Saturday, or Sunday, it first started on the Monday of the following week.Footnote 58

Finally it must be taken into account that in the imperial city Frankfurt, as well as in Ansbach, the old Julian calendar was still valid until 1700 (Brübach 1994, p. 136). However, in the Republic of the Seven United Provinces (the Netherlands), the Gregorian calendar had been valid since 1582.

Taking all these conditions into consideration, the date of the beginning of the fair, determined by Emil Wohlwill, responds exactly: “Nach Erkundigungen, die ich im Frankfurter Archiv eingezogen habe, wurde die Frankfurter Herbstmesse des Jahres 1608 am 12. September eröffnet […].”Footnote 59 On the Julian calendar of 1608, the Nativity of Mary fell on a Thursday; the following Monday was September 12.Footnote 60 On the Gregorian calendar, this Monday was already September 22.

In the second half of the sixteenth century, there were 18 fair days in Frankfurt (Brübach 1994, p. 31). This might have been the same in 1608, because the original fair date between August 15 and September 8 also stretched over approximately 3 weeks. I assume that the 18 fair days mentioned excluded Sundays and the fair took place on 3 × 6 days. Thus, the last day would have been Saturday, October 1, on the Gregorian calendar October 11.

The dating by Wohlwill and the calculated end of the 1608 fair are confirmed by the following archival registrations: “Anfang der Herbstenmeß. NB. Ist die Meß ausgeleut worden donnerstags vf Nat. Mar. vor anfang der Meß.”Footnote 61 So the fall trade fair of 1608 started after Nativity of Mary, in accordance with the rules above on the following Monday, September 12 (Julian date). “Alß man Montags den 3t. 8bris 1608 nach vollend[er] herbstmeß an den Veltpf[orten] vfgeschlossen, Ist seither jungsten Meß vber gefallen [...].”Footnote 62 So in 1608 the fair was finished before October 3, according to the calculations above, on Saturday, October 1 (Julian).

A verification of the begin and end of the 1608 fair using contemporary calendars seems impossible, though they also included fair dates (they are missing in Marius’s own calendar for 1608). I was unable to consult a calendar for 1608 other than Marius’s; however, an example for 1606 only mentions the start of the fair and that only approximately.Footnote 63

As for the presence of the merchants, it must be taken into account that they arrived and left only in large “Geleiten” (convoys) because of the danger of holdups. By imperial order, these convoys had to be protected by the respective sovereign ([Orth] 1765, pp. 75–99; Dietz 1910/1970, pp. 41–44). Less than ten convoys existed that were obviously assembled in some meeting places in larger cities and were composed of mounted merchants, four-in-hand freight carriers, and numerous (certainly armed) escorts. In 1446 the Nuremberg convoy, though quite small in that year, was composed of 250 people, 450 horses, and 69 carriages (Dietz 1910/1970, p. 61). The convoys arrived before the official beginning of the fair, on Wednesday or Thursday of the previous week, and the merchants unpacked their goods (Dietz 1910/1970, p. 40 and 44).

As to the further procedure of the fair, there are different claims; a Frankfurt jurist and (amateur) historian Alexander Dietz claimed, without source references, first a business week and then a week to settle up (Dietz 1910/1970, p. 40). A new academic investigation refers to 5 days of accounting for the repayment of debts, followed by a week of trading for the sale of goods (Brübach 1994, p. 310). The convoys “wurden in der dritten Woche […] großenteils schon am Dienstag abgeführt. Als letztes zog am Samstag Nachmittag das hessendarmstädtische ab.”Footnote 64 Residual sales to small customers were continued until 3 p.m. on Saturday (Dietz 1910/1970, pp. 40–41).

We don’t know how long Fuchs von Bimbach stayed in Frankfurt in 1608. Considering the long distance, about 200 km, between Frankfurt and Ansbach, it would probably have been a 3-day ride,Footnote 65 and taking into account the many things, he would have had to accomplish and to enjoy, and he certainly would not have stayed for only a couple of days. Let us suppose that he stayed until the middle of the third week and left, for example, on September 28 (a Wednesday in Julian calendar); he would have arrived at Ansbach not earlier than the evening of September 30 (October 10 in Gregorian calendar). At least, it is very unlikely that he would have returned before the beginning of October (Gregorian). If Frankfurt was only an intermediate stop on a longer journey, his return might well have been significantly delayed.

Dutch merchants had a far longer journey of about 450 km, and with loaded carriages and in a large convoy, the traveling speed would have been much slower than for riders. We can certainly calculate 10 days for the journey if not more. Such a trip was only worth it if one stayed in Frankfurt for the whole fair, so that the Dutchmen would have only returned to Amsterdam or other places at the earliest around October 20 (Gregorian). In individual cases merchants might have traveled without a convoy, though a very short stay also seems unlikely for them, considering the long, arduous, and dangerous route. This also applies to the visitors.

Fuchs, Marius, and the Telescope

Everything in the literature on how Simon Marius got his first telescopes obviously goes back to his own presentation in Mundus Iovialis and is only occasionally supplemented with details, which are not to be found by Marius. Though often cited, Marius’s account will be repeated literally, because in certain details the exact wording is important. Primarily, Prickard’s and van Helden’s translation is used. A new analysis of the Latin original with regard to the following considerations would be desirable:

In the year 1608, when the Frankfurt autumn fair was going on, it happened that there was at the same place the most noble, gallant, and energetic John Philip Fuchs, of Bimbach in Mohr, […] Various things went on there, and among others it chanced that a certain merchant met the nobleman mentioned above, whose acquaintance he had formerly made, and told him that there was then present in Frankfurt at the fair a Belgian, who had invented an instrument by means of which the most distant objects might be seen as though quite near. Hearing this, he begged the merchant to bring the Belgian to him, which the merchant at last consented to do. Our nobleman had a long discussion with the Belgian first inventor, and felt doubts as to the reality of the new invention.Footnote 66

This “first inventor” (“primus inventor”) is unknown. Cornelis de Waard drew in 1906 the conclusion, “dass es sich mit großer Wahrscheinlichkeit um Sacharias Janssen gehandelt hat.”Footnote 67 Arjen Dijskstra argued that it could have been Jacob Metius , who would have had the best reasons to travel to the Frankfurt fair.Footnote 68 To discuss this question, we have to recapitulate, which inventors of telescopes are currently known.

It is recorded that Hans Lipperhey and Jacob Metius applied for patents on their inventions on October 2 and 15, 1608, respectively. They were both refused because neither was the unique inventor. A document from October 14 quotes, in this context, a third, unnamed inventor (Van Helden 1977, pp. 36–40). Earlier in the literature, Sacharias Janssen was supposed to be this third inventor. But Huib Zuidervaart argued convincingly that Janssen was unable to create telescopes in 1608 and proposed Lowys Lowyssen as a more suitable candidate (Zuidervaart 2010).

If the “Belgian” whom Fuchs met was a merchant, stayed until the third fair week, and left with a convoy, so according to the calculation in the previous section, it probably wasn’t one of the two known inventors, because they wouldn’t have made it home until October 15. Lipperhey can be excluded, and also Metius had to leave significantly before the fair ended, which seems unlikely, however not impossible. Apart from the known inventors, there might have been another Dutch optician, who manufactured a functioning telescope in 1608:

At last the Belgian produced the instrument, which he had brought with him, and one glass of which was cracked, and told him to make trial of the truth of his statement. So he took the instrument into his hand, and saw that objects on which it was pointed were magnified several times. Satisfied of the reality of the instrument, he asked the man for what sum he would produce one like it. The Belgian demanded a large price, and when he understood that he could not get what he first asked, they parted without coming to terms.Footnote 69

A detailed analysis of this report shows that the demonstration of the first telescope was a private, nonpublic matter. Fuchs von Bimbach didn’t meet the “Belgian” himself but heard about him through an acquaintance. The owner didn’t demonstrate his instrument straight away but only after a lengthy discussion. Therefore it can’t be concluded that this telescope was offered for sale at the fair. Without the merchant, who he had known for some time, Fuchs von Bimbach probably would not have heard about the telescope. The “first inventor,” e.g., a spectacle maker, could have been selling lenses and glasses or in the case of Metius his brother’s new book. However, Marius’s report nowhere states why he was at the fair; he might as well have been a visitor just like Fuchs and not a merchant.

In the literature about Marius, it is presumed that Fuchs von Bimbach was interested in the telescope for military reasons. This is an obvious assumption as Dutch documents of 1608 mention this and also a desired secrecy; but there are no statements by Fuchs or Marius about this. We also don’t know if Fuchs ever used one of the instruments he later bought for military purposes. As he handed them over to Marius, his interest might well have been purely scientific. The image quality of the first telescopes was very low and their field of view very limited, so their military value was low. It would be desirable to find out since when telescopes were actually used for military purposes.

Also the conclusion that there was no trade because of the large price claimed is just a presumption. The main reason may have been that “one glass […] was cracked.” The statement “The Belgian demanded a large price” may not necessarily have been the reason that “they parted without coming to terms.” We don’t know what sum had been demanded, whether Fuchs eventually would have accepted it, if a usable instrument had been for sale immediately, and how much he paid nearly 1 year later for a Dutch instrument. The repeated mention of the high price as an obstacle for the sale certainly goes back to Klug, whose original translation of Mundus Iovialis was truncated and therefore false: “Der Belgier verlangte eine hohe Summe; deswegen zerschlug sich der Handel.”Footnote 70 Anyway, Fuchs couldn’t get a telescope at once, and the “delivery” of another copy under the prevailing conditions would certainly have taken a long time, maybe even until the next fair. The attempt to build his own telescope could have been a question of time rather than costsFootnote 71:

When he returned to Ansbach, the Nobleman sent for me, and told me that an instrument had been devised by which very remote objects were seen as though quite near. I heard the news with the utmost surprise. He frequently talked the matter over with me after supper, and at last came to the conclusion that such an instrument must necessarily be composed of glasses, of which one was concave, the other convex. He took up a piece of chalk and with his own hand drew a sketch on the table to show what sort of glasses he meant. We afterwards took glasses out of common spectacles, a concave and a convex, and arranged them one behind the other at a convenient distance, and to a certain extent ascertained the truth of the matter.Footnote 72

The calculation above shows that Marius probably wouldn’t have met Fuchs and heard about the telescope before October 10 (Gregorian date).

Marius’s report shows that he had never before heard or read about the possibility of such an instrument, though the enlarging effect of such a combination of lenses had been known since the sixteenth century (Van Helden 1977; Willach 2007, pp. 105–109). Rolf Willach assesses that at the end of this century, “die Kenntnis des teleskopischen Effektes sicher weithin Allgemeingut unter den Brillenmachern und Gelehrten geworden war.”Footnote 73 At least for Marius this was not correct; it is not generally known if he had been concerned with optics before or after 1608 and his access to scientific literature was limited. In contrast to Kepler, he just used telescopes and didn’t care about their construction and theory. So unfortunately, we have no detailed specifications of his instruments, only a picture together with his portrait (see Fig. 5.2).

It must also be doubted whether Fuchs von Bimbach knew about the telescopic effect of a combination of a concave and a convex lense before. It is therefore all the more remarkable that he recognized the form of the lenses in the telescope he inspected in Frankfurt. As he was probably about 40 years old, he could have been in contact with spectacles and their makers. However he failed to notice something else—the diaphragm, with some certainty, present in front of the objective lens.

Experimenting with two spectacle lenses, Fuchs and Marius persuaded themselves of the magnifying effect of the lens arrangement. Thus they repeated what others had found out decades before; however just like their predecessors, they were unable to construct a telescope with only this knowledge:

But as the convexity of the magnifying-glass was too great, he made a correct mould in plaster of the convex glass, and sent it to Nuremberg to the makers of ordinary spectacles that they might prepare glasses like it; but it was no good, as they had no suitable tools, and he was unwilling to reveal to them the true principle of the process. No expense was spared, and several months elapsed. If we had been acquainted with the method of polishing glasses, we should have produced excellent spy-glasses immediately after our return from Frankfurt.Footnote 74

With the last sentence, Marius was fundamentally wrong. Rolf Willach, who examined numerous sixteenth-century spectacle lenses, stated that most of them were of insufficient quality to be used in telescopes. He concludes “dass die Erfindung eigentlich nur einem guten Brillenmacher gelingen konnte, dem ein entsprechend großer Vorrat an Linsen für seine Versuche zur Verfügung stand. Gelehrte und Halbgelehrte […], welche vielleicht bestenfalls über ein halbes Dutzend Gläser verfügten, hatten nur eine sehr geringe Chance.”Footnote 75

For the construction of a telescope, the magnification effect is insufficient; one also needs to produce a sufficiently sharp image. Most lenses didn’t provide the necessary result because the quality of the glass was inadequate and/or they were not ground well enough. In 1608 and the following years, even the best lenses needed a modification to meet with the requirements of a telescope, a diaphragm that reduced the aperture of the objective. This improves the quality of the image significantly. Willach found that around 1608 lenses were only a little better than before and it was only the diaphragm, which led to the decisive breakthrough. For example, a lense of 3 cm diameter was stopped down to 1 cm. He proposed the thesis that the telescope only gained such a rapid dissemination by copyists because a craftsman immediately noticed the diaphragm in front of the lens.Footnote 76

But Fuchs and Marius were no experts; the function of the diaphragm obviously remained unknown to them because it is nowhere reported. Therefore and because of their small selection of lenses, they were unable to recreate a telescope. All future purchases were of complete telescopes.

In the Marius literature, there is discussion that the failure of Fuchs and Marius was because Fuchs “was unwilling to reveal to them [the Nuremberg spectacle makers] the true principle of the process.” Apart from the fact that Fuchs’s understanding of this method was minimal and his knowledge was not sufficient to construct a telescope (which Marius however didn’t know), this statement is dependent on the correct translation. In the original it says “veram conficiendi rationem illis revelare noluit.” The translator Joachim Schlör pointed to the form of “revelare” in this sentence that is basic to his German translation (Schlör 2012, p. 57 and 59), which is similar to the English one used here. Josef Klug translated the sentence more than 100 years before as “das Geheimnis der Fertigstellung wollte sich ihnen [den Brillenmachern] nicht offenbaren”Footnote 77 for which according to Schlör the form in the sentence had to be “revelari.” So one letter, e or i, makes a significant difference in the statement. On the other hand, Schlör lists some grammatical mistakes in Mundus Iovialis, and, as the chapter by Richard Kremer in the present volume shows, Marius’s publications are not always clear in their claims and partially incorrect. As well as an inaccurate formulation or a grammatical mistake made by Marius, a printing error of the typesetter is also possible, who misunderstood the meaning of the sentence or didn’t understand it at all. As was discussed above, there is no other proof that Fuchs was interested in secrecy for military reasons. Actually he had to assume that sooner or later others would also receive a telescope from the Netherlands or copy one. The interpretation of Klug, though grammatically wrong, seems more plausible to me. At least one can’t clearly decide between the two possibilities. Whatever choice is made, the reason for the failure to construct a telescope was another one. Because of its dubiousness, it is inadequate as proof of Fuchs’s pursuit of secrecy; equally through circular reasoning, the assumed secrecy cannot be used as proof of the correctness of the new translation—for which the only evidence is the letter “e”.

In the meantime, glasses of the same kind were becoming common in Belgium, and a fairly good one was sent, with which we were highly pleased. This was in the summer of 1609. From this time I began to look into the heavens and the stars with this instrument, whenever I was at the house of the nobleman so often mentioned, at night time; sometimes he used to allow me to carry it home, and in particular about the end of November, when I was observing the stars according to my custom in my own observatory.Footnote 78

In October 1608 Marius was probably the first astronomer outside of the Netherlands who learned about the invention of the telescope, but it took about another 9 months until he could hold one in his hands.

Though Marius wrote “a fairly good one was sent,” it was obviously Fuchs’s property, who with certainty paid for it. At first, Marius was only sometimes allowed to take it home. As Marius could not expect assistance from the Ansbach court, which was always in financial difficulties, Marius stayed dependent on a private sponsor.

Arjen Dijkstra noted that in June 1609 Adamus Valentinus Fuchs von Bimbach was enrolled in Leiden and could have got the telescope for his relative in Ansbach.Footnote 79 But there is no proof for this until now. Adam Valentin Fuchs von Bimbach zu Burgbreitbach (= Burgpreppach), younger son of Georg Fuchs von Bimbach zu Gleisenau, was a generation younger than Hans Philip Fuchs von Bimbach zu Möhren and was related to him in the male line through his great-great-grandfather (Biedermann 1747, Tabvla LX; Flurschütz da Cruz 2014, p. 385).

Meanwhile, two glasses extremely well polished, a convex and a concave, were being sent from Venice by that most distinguished and accomplished man, the Lord John Baptist Leuccius,Footnote 80 who had returned from Belgium to Venice after peace was made, and who had already been thoroughly acquainted with the instrument. These glasses were fitted into a leaden tube, and made over to me by the most noble and active nobleman whom I have mentioned already, in order that I might try what they would show among the constellations and stars near Jupiter. Accordingly, from this time until January 12, I gave my diligent attention to these Jovian stars … .Footnote 81

As the lenses were “fitted into a leaden tube,” Marius in this case also received a complete telescope. In Venice particularly high-grade glass was produced so that the lenses in Marius’s and Fuchs’s second telescope were probably better than those in the first. The receipt of this instrument can be dated around mid-January 1610 (Gregorian calendar), as Marius reports his observations made earlier with the first telescope that he recorded from December 29, 1609 (Julian date) on. He received the new instrument obviously some days before January 12, 1610 (Julian date). This time he didn’t have to observe at Fuchs’s home but could take the telescope home immediately. From January 13 until February 8, Marius traveled and left the instrument at home. Afterward he continued his observations with this telescope and got it from Fuchs as a gift or “permanent loan,” because:

In order that I might observe the Jovian stars with greater closeness and diligence, the illustrious nobleman whom I have frequently mentioned, out of his special affection towards these astronomical studies, placed the instrument entirely at my disposal. From that time accordingly to the present, I have made continuous observations with this instrument and with others afterwards constructed.Footnote 82

About the “afterwards constructed” instruments, nothing is known, also not how Marius obtained them. Had prices lowered since then, so he could afford them himself or did Fuchs von Bimbach help again? We don’t know. It can be excluded that Marius could construct them himself. He lacked the necessary manual skills and knowledge, the indispensable tools, the access to good glass or numerous finished lenses, and the abilities of an experimenter. As opposed to Galilei, there is no information that Marius had carried out experiments. Self-constructing would have taken a lot of time and he certainly would have written about it. The production of the annual calendars and prognostica might have left him with no time for the complex construction of telescopes.

Indirectly Marius makes Fuchs a witness to the correctness of his report about the acquisition of telescopes and the observations made with them:

This is the exact truth. I should never be allowed thus in a public document to say what was not true about so great a man […].Footnote 83

Marius might have remembered incidents from the past when others wanted to “say what was not true” about Fuchs von Bimbach. It was just around 1614 that Fuchs vented his anger about two court officials who mocked him through indiscretion and finally even addressed the Reichskammergericht (Imperial Chamber Court) (Herold 1973, p. 46).

The Translation of Euclid

Marius’s translation of Euclid , which was published in 1610, is discussed by Hans Gaab in more detail (section “Life at Court and Publications” in Chap. 2; see also Fig. 2.14). Here we only outline Fuchs von Bimbach’s intentions with this book.

The title page and the introductions show that Marius did the translation at Fuchs’s instigation. The title page also mentions the applications: “Alles zu sonderm Nutz denjenigen/so sich der Geometria/im Rechnen/Kriegßwesen/Feldtmässen/Bauen/vnd andern Künsten vnnd Handtwerckern zugebrauchen haben.” (“Everything shall be of special profit to those who have to use geometry, in reckoning, warfare, field surveying, constructing and other arts and crafts.”)

Fuchs added an introduction, dated January 1, 1610 in which he, after a detailed explanation why the German language is important for such books, described the applications:

[…] zuforderst aber im Kriegswesen/die jenigen/so Quartier schlagen/Schantzen/Vestungen etc. bawen vnd zervbrechen/mit Zeug: oder Geschützwesen/Werkcken […] Wie viel sind der Werckleut/deren handtwerck allein auff der Geometria bestehet?Footnote 84

He explained which mistakes architects and builders make because they know too little about geometry and asked:

Inn was grossem Irthumb stecken die Landtmässer? Deren meiner Mainung nach gar nimmer/oder selten zwen gefunden/die in dem facit übereinstimmen […].Footnote 85

He estimated which errors come together in large areas (10,000 acres) when small errors are made in measuring and reckoning.

As an officer Fuchs occasionally must have come into contact with geometry, e.g., when directing a canon or using maps. Ruling over several territories where border conflicts happened, Fuchs had a relationship to surveying. As owner of a castle, he employed architects, builders, and craftsmen.

However, it seems astonishing to use Euclid’s rather abstract book for these practical purposes instead of an instruction manual for land surveyors or other textbooks. But at that time Euclid’s book was the primary text among the introductions to geometry. Fuchs had probably first heard about it at school in Lauingen. He wrote on the significance of Euclid’s “Elements” that they “der gantze grundt und Fundament der Geometria seind” and “in vielen Handthierungen vnvermeidtlich gebraucht muß werden.”Footnote 86

He then expresses his hope that the margraves of Ansbach and Bayreuth to whom the book is dedicated:

nicht allein […] mir zu gut halten/Daß gedachten dero Mathematicum [d.h. Marius] ich dieser Verdeutschung/So gleichwol nicht ohne sondere Mühe und Versäumnuß abgangen/an vnd vielleicht von andern Verrichtungen abgehalten/Sondern auch mit ihm Allergnädig zu frieden seyn […].Footnote 87

Marius writes in his introduction that his translation:

geschehen ist auß Befehl deß Edlen vnd gestrengen Herrn Hanß Philips Fuchßen von Bimbach etc. So der Geometrischen sachen nicht allein ein besonderer Liebhaber vnd Beförderer ist/sondern daß der Anfang vnd Grunde denjenigen/so sich darinnen zu üben willens zu wissen für hochnötig geachtet/vnnd durch sein vielfältiges nachfragen experimentiren vnnd außsinnen/den gewaltigen vnd groben Irrthumb vermercket/darinnen gemeine Feldtmässer alle mit einander stecken/und daher in Kauffen und Verkauffen grosser und augenscheinlicher irrthumb vorgehet […].Footnote 88

Afterward he lists further applications of geometry in which ignorance leads to mistakes. If Marius was not exaggerating, Fuchs von Bimbach seems to have engaged intensively with geometry and its applications, through “manifold inquiries, experiments, and cogitation.”

Attempt to Assess of Hans Philip Fuchs von Bimbach

To describe Fuchs von Bimbach as a shrill figure (Buchner/Mavridis 2009, p. 78) because of his switching sides and his combativeness is too shortsighted. To a certain extent, the same applies to him, as was written about his liege lord, Margrave Joachim Ernst of Ansbach, “daß auch er von den Tendenzen seiner Zeit zum Abenteurertum nicht unberührt geblieben war, die den Individualismus übersteigerte und das KondottierentumFootnote 89 förderte. Immer haftete seinen politischen Entscheidungen etwas Verwegenes an. Zudem gingen Joachim Ernsts religiöse Bindungen nicht sehr tief.”Footnote 90 However, Fuchs’s military book and his military and political approach show him to be more prudent than Joachim Ernst or King Christian IV. As an imperial knight, officer, and a landlord, he was typical for his times.

Changing sides for actual or supposed advantage was common, also for sovereigns. In this, Fuchs von Bimbach probably followed his main liege lord and patron, Wolfgang Wilhelm of Palatinate-Neuburg.

The tendency to quarrels was also widespread. “Adelige des 16. Jahrhunderts befanden sich anscheinend mit jedermann in Konflikt.”Footnote 91 In distinction to earlier centuries, blood feuds had been replaced by confrontations in court, at least on a regional level. In the disputes about power and territories between the emperor and the sovereigns, between realms and religious confessions, war was often the chosen solution.

Fuchs von Bimbach was primarily an officer; he was a politician only for a few years of his life. Naturally, during all the years, he also had to supervise the administration of his territories, but not much is known about this to date.

In the early modern era, it was absolutely common to plunder in order to finance war and also for personal enrichment. A colonel like Fuchs von Bimbach was not only an officer but also a small-scale businessman. He had to employ his subordinated officers and foot soldiers temporarily and to pay them. For this he did not always get money from his employer but also had to acquire credit, and for their repayments sufficient revenue had to be generated.Footnote 92 For the spoils of war, there were quite fixed rules, for example, what share of the conquered canons a quartermaster had to give to the colonel. There was also an official (Beutmeister), who was responsible for “fair” distribution. Which part of Fuchs’s large assets came from the military expeditions and what was from other sources (inheritances, high income in Ansbach, financial investment, management of goods) can’t be answered here.

In Ansbach Fuchs seems not to have been liked—except by Marius and in the beginning by the Margrave. Other court officials complained about him (envy certainly played a role here); when his star began to descend, satirical poems circulated and finally he fell from the Margrave’s grace.Footnote 93 It is hard to decide what was true about his alleged immoral way of life and his “course” manners, and what was exaggerated or even fictional.Footnote 94 Marius must have known the accusations but nevertheless praised him highly.

Christian IV made Fuchs posthumously responsible for the defeat at the Battle of Lutter, but it seems that he was diverting attention from his own unsound decision (Zwanziger 1920, p. 14). In the older military literature, it is said: “Fuchs stand bei Freund und Feind als alter, erfahrener und listiger Kriegsoberster in sehr großem Ansehen und war der ausgezeichneteste Officier in der königlichen [dänischen] Armee.”Footnote 95

In the Fuchs von Bimbach family, Hans Philip obviously was held in high esteem. In 1682 a young family member is admonished that he should “in weyland Hannß Philipp Fuchs von Bimbach, Fusstapfen tretten, und eben den Nachruhm hinterlaßen möge, daß er in angeführten Wißenschafften wohlerfahren, und Oberster geworden seye […].”Footnote 96

However, basically Hans Philip failed in his principal occupations. He was not particularly successful either as a politician, a diplomat, or an officer, which however in the given constellation of various parties, interests, and confessions of the period was extremely difficult; Wallenstein has gone down in history and in art as a similarly failed player. In his three most important positions as court official in Ansbach, imperial colonel, and general of the Dutch King, Fuchs suffered extensive slights and died finally as a defeated military commander.

His interest in sciences was less pronounced than, for example, his contemporaries Rudolf II or Maurice of Hesse-Kassel (called “The Learned”). According to Simon Marius, he was “not only benefactor and admirer of the whole of mathematics and other similar sciences but also their greatest patron.” A remaining merit for the cultural history of mankind is the support of Simon Marius and one of the first astronomical uses of the telescope. Fuchs von Bimbach would probably have considered it an insult if he had ever imagined that four centuries later he is appreciated for his support of astronomy but not for his service in battle.

Errors and Speculations About Fuchs von Bimbach in the Literature

Unfortunately, all existing biographies about Fuchs von Bimbach contain errors and speculative statements that are formulated as facts, which is also true for the statements about Fuchs in the literature about Marius. Without any claim to completeness, some of these mistakes that are perpetuated again and again without verification will be listed here. Further minor errors have already been discussed in the text above and in the footnotes.

The errors begin with his name. In an eighteenth-century review of people with the family name “Fuchs,” he is falsely called “Johann Philip Fuchs von Fuchsberg.”Footnote 97

In the Braunschweigisches Biographisches Lexikon, he is registered as “Fuchs von Bimbach, Hans Philip Freiherr von” (Lent 2006), what rewritten would result in “Freiherr von Fuchs von Bimbach.” Apart from the wrong title “Freiherr” (baron, see below), “Hans Philip von Fuchs von Bimbach” is meaningless. Dijkstra refers to him in short as “Von Bimbach,” what is also inadmissible (Dijkstra 2012, p. 137 and 138). The family name was Fuchs; “von Bimbach” was an addition to mark the lineage. Later family members were called “Freiherr Fuchs von Bimbach [und Dornheim],” in no case “Freiherr von Fuchs von Bimbach” or “Freiherr von Bimbach.”

In the earlier literature both first names are always used, although in various spellings. It is not known whether there was a preferred first name. Joachim Schlör repeatedly uses only the second name PhilippFootnote 98 what seems unreasonable to me because in contemporary documents both names are always used.Footnote 99

Occasionally 1567 is stated as his year of birth,Footnote 100 but the exact year is unknown. 1567 is just a plausible but unsubstantiated presumption.

In 1892 Julius Meyer speculated about Marius’s choice of Padua as his place of study: “Von Einfluß auf die Wahl der Universität Padua mag auch der Umstand gewesen sein, daß sein Landsmann, der markgräflich onolzbach’sche Geheimrath und Kriegsoberste Freiherr Hans Philipp von Fuchs-Bimbach auf Möhren [...] i. J. 1587 auf derselben Universität seine wissenschaftliche Ausbildung genommen hatte.”Footnote 101 This sentence is full of mistakes and unproven claims. Fuchs’s attendance at the University of Padua is not documented, nor is his influence on Marius already recorded in 1602. Besides the name of the family line (von Fuchs-Bimbach) is wrong. Strictly speaking he wasn’t a fellow countryman of Marius, but came from neighboring Palatinate-Neuburg. Fuchs was no “Geheimrat” (privy councilor)—at least not in the meaning of this title as used in the nineteenth century—and not a baron. This title is wrongfully ascribed to him in many publications. This claim of studies in Padua and the title Freiherr were also included in the biographical Wikipedia articleFootnote 102 and in the record in the “Gemeinsame Normdatei (GND)” of German libraries, which obviously was based on the Wikipedia entry.Footnote 103

A newer essay about Marius and the telescope says: “Janssen stellte bereits 1608 sein Fernrohr auf der Frankfurter Messe vor.” “Im Herbst 1608 erfuhr Marius vom Artillerie-Offizier, Freiherr Hans Philip Fuchs von Bimbach, daß auf der Frankfurter Herbstmesse Fernrohre angeboten wurden […].”Footnote 104 As explained above, there is no direct evidence, who had the telescope in Frankfurt; that it was Sacharias Janssen is not a fact, but a theory. Marius’s report mentions one telescope, not telescopes in the plural. From Marius’s report it can’t be concluded that the telescope was “presented” in public and “offered for sale.”Footnote 105 To name Fuchs von Bimbach, an artillery officer (a modern term) is not accurate for the year 1608; this can only be stated for later years, as he belonged to the “infantry” (also a modern term) before 1610.

Naming the “inventor” who showed Fuchs von Bimbach a telescope at Frankfurt am Main a “merchant”Footnote 106 is pure speculation. It might originate from the presumed identification with Janssen who among other things was a merchant.

At this point attention will be drawn once more to a popular error concerning Marius. He didn’t construct his own telescopes as is often claimedFootnote 107 but used complete ones. That he received his first telescope in October 1608Footnote 108 appears much too early; he only got it in summer of 1609.

An extremely absurd statement can be found in a popular book about historical places in Lower Saxony, in this case about the battlefield of Lutter: “Unter den Toten auf protestantischer Seite befand sich auch General Fuchs […] Dieser aus Bayern stammende Haudegen, der mit vollem Namen Hans Philipp Freiherr Fuchs von Rimbach [sic] hieß, war eine recht ungewöhnliche Persönlichkeit. Er war eigentlich Astronom und hatte entscheidenden Anteil daran, daß im Jahre 1610 Galileo Galilei die Entdeckung der vier Jupitermonde gelang. Zudem war Fuchs Mathematiker und Herausgeber der ersten 15 Bücher des altgriechischen Mathematikers Euklid. Was ihn in den Krieg getrieben hat, wußte wohl nur er selber.”Footnote 109 This needs no comment. However, this “source” was used to create an article for Wikipedia about the Battle of Lutter in which the general was called a “kursächsischer Mathematiker und Astronom” (“mathematician and astronomer from the Electorate of Saxony”).Footnote 110 As a curiosity I remark that it was just this crude mistake that first drew my attention to the Franconian imperial knight. Through an Internet search in 2007 for memorial stones, etc. about astronomers, I found this Wikipedia page about the Battle of Lutter and the “astronomer” Fuchs von Bimbach who was missing in the Biographical Index of Astronomy (BIA) (Brüggenthies/Dick 2005). Though he wasn’t an astronomer, we have meanwhile included him together with other patrons of astronomy in the second edition of the BIA (Brüggenthies/Dick 2017).

Source Situation and Approaches for Further Researches

Until now there is no academic biography of Fuchs von Bimbach, only popular portrayals and a few encyclopedia entries, as well as a lot of details, spread over numerous publications. Almost all sources cited here in turn refer to older sources that also had to be consulted for a comprehensive biography. The existing printed material would be enough to write a book about Fuchs von Bimbach, but without intensive archival studies, this would be of only small academic value.

The most comprehensive biography until now is by Karl Hermann Zwanziger of 1919/20 that contains much interesting data but unfortunately indicates its sources insufficiently. A newer one can be found in a local history book about Unterschwaningen (Buchner/Mavridis 2009); it cites its sources fairly precisely but is also based on unreliable ones and gives room to speculations that are not marked as such. These local history researches and publications are often very valuable because they exploit local sources—but unfortunately often lack exact references and are not always on an academic level. The latter also applies to many publications of the early twentieth century and before; however, their authors had access to archival documents that have in the meantime been lost. As well as the already quoted biographies, there is a completely useless one of 1899 (Clementi 1899; based on Meyer 1892 and Lichtenstein 1850) that, however, was used repeatedly as a source for others and another one without value from 1982 ([Klay?] 1982).

With one exception everything known about the relationship between Fuchs and Marius, as well as about their acquisition and use of telescopes comes from Marius himself. Independent sources would be valuable but have not been found to date. The extensive literature about the early history of the telescope and about Marius offers at least various approaches as to how Marius’s descriptions can be interpreted and classified in the comprehensive history of the telescope. This literature could only be reviewed to some extent here.

In the literature about the Thirty Years’ War and especially about the Battle of Lutter, Fuchs von Bimbach is mentioned repeatedly; this could also only be used very selectively here. The only entry in a big (printed) biographical reference book, the Dansk biografisk leksikon (Danish biographical encyclopedia)Footnote 111 only deals with his time in Danish military service and is of little biographical use. Additional findings about his military career up to 1610 may be won from his own memories in the Stuttgart manuscript (see section “Fuchs von Bimbach as a Military Author”).

Many details to Fuchs von Bimbach at the Ansbach court on an archival basis are presented in the dissertation by Hans-Jörg Herold about Joachim Ernst (Herold 1973). At the same time, it demonstrates how much previously unknown data can be found in archives. The newer dissertation of Andreas Flurschütz da Cruz deals with a conflict between the Franconian knight families Fuchs von Bimbach and Wolf von Wolfsthal in the second half of the seventeenth century but contains also valuable information about previous family history and references to archival holdings especially in Franconia, among them the Fuchs von Bimbach family archives.Footnote 112 Numerous other files in state, ecclesiastical and private archives mentioning Hans Philip Fuchs von Bimbach might exist. To him, his ancestors and siblings information might also be found in archival documents about the Neuburg/Donau and Jülich courts, in maybe still existing parish registers of Neuburg and Möhren, in imperial files in Vienna and Prague, in Dutch and Danish archives, maybe also in Padua and elsewhere. And probably there, in a remote place, Simon Marius is also named … .
