[edit] Life

Christmann, a Jew who converted before 1578 to Christianity, studied Orientalistics at University of Heidelberg's Collegium Sapientiae and became teacher at Dionysianum. He followed humanist Thomas Erast to Basel and back to Heidelberg. Later he went to Breslau, Wien and Prag.

In 1578, Pfalzgraf John Casimir founded the Lutheran Casimirianum at Neustadt an der Haardt where in 1582 he dedicated to his colleagues his Arabian language Grammar Alphabetum arabicum.

He returned to Heidelberg when Lutherans were accepted there again, to be appointed in 1584 Professor for Hebrew. He compiled a catalogue of the manuscripts of Guillaume Postel (1510-1581), located since 1551 at Heidelberg castle. In 1590 he published a Latin translation of the astronomy of Al-Farghani.

In 1608, he was finally appointed Europe's first professor for Arabian.

[edit] Copernicus manuscript

A De revolutionibus manuscript of Nicolaus Copernicus passed[1] via Rheticus to others and was marked on 16 December 1603 by Christmann with Nicolai Copernick Canonici Varmiensis in Borussia Germaniae mathematici … („of Canon Nicolaus Copernick from Warmia in Prussia of Germany, of the mathematician …“) [2]. Since 1953 it is located in Cracow in the Jagiellonian library (Signatur: Ms. BJ. 10 000), accessible online.

Rheticus took it to Leipzig and Cracow (1554 - 1574) and to Kosice (Kaschau) where he died and left it to his pupil and colleague Valentin Otho (1545 - 1603) who took it to Heidelberg were Jakob Christmann (1554-1613) added his remark. From his widow the manuscript was sold on 17 January 1614 to Comenius (1592-1670), who left a remark [1] signed as Johannes Amos Niuannus. On 5 October 1667 it was part of Bibliotheca Maioratus Familiae Nostitizianae' (1608-1664) library at Jauer in Silesia, Otto von Nostitz left his signature [2] on the flyleaf. The Nostitz library was then moved to Prague where in 1945 the collection of Nostitz library in Prague was seized by the communist government of Republic of Czechoslovakia, and made part of the National Museum (Prague). On 7 July 1956 the government of Czechoslovakia gave it as part of an exchange to their Polish comrades, and since 25 September 1956 it is at the Jagiellonian University in Cracow.
