FIRST EDITION of Peurbach and Regiomontanus's epitome of Ptolemy's encyclopaedia of astronomy, the Almagest or Mathematical syntaxis, and the only edition to be printed in the 15th century, preceding the first complete edition by 20 years (a full Latin translation appeared in 1515). In 1460 Peurbach, professor of astronomy at the University of Vienna, was persuaded by Cardinal Bessarion, then papal legate to the Holy Roman Empire, to undertake a "briefer and more comprehensible" Latin condensation of Ptolemy's formidably complex Syntaxis. Ignorant of Greek, Peurbach based his epitome on a copy that he himself had transcribed of Gerard of Cremona's 12th-century translation. He died just after completing Book VI, and the remaining seven books were completed, using a more accurate manuscript, by his former student, friend and colleague Johannes Mller of Knigsberg (Regiomontanus), who dedicated the final text to its patron Cardinal Bessarion. In Regiomontanus's manuscript, preserved in the Institut de France, he did not address Bessarion as Patriarch of Constantinople (a title which is used in the printed edition), showing that the manuscript must have been completed before 28 April 1463, the date upon which the Cardinal was granted that title. The manuscript appears to be listed (as "Breviarium Almaiesti") as one of many pending projects announced by Regiomontanus on the printed broadside advertisement of his short-lived Nuremberg press and instrument shop (H *13807). It was not however printed until 20 years after his death. "By providing easier access to Ptolemy's complex masterpiece, the Peurbach-Regiomontanus Epitome contributed to scientific research rather than to improved understanding of the past. Moreover, the Epitome was no mere compressed translation of the Syntaxis, to which it added later observations, revised computationsa, and critical reflections..." (DSB 11:349).
