Georg Joachim Rheticus (Frontpage of "Canon Doctrinae Triangulorum")


Austrian mathematician, astronomer, cartographer, navigational-instrument maker, medical practitioner, and teacher. He is perhaps best known for his trigonometric tables and as Nicolaus Copernicus's sole pupil. He facilitated the publication of Copernicus's De revolutionibus orbium coelestium (On the Revolutions of the Heavenly Spheres).

In 1552, Rheticus was found guilty of raping the son of Hans Meusel, a merchant, though the exact nature of this encounter has been called into question. According to Meusel, Rheticus "plied him with a strong drink, until he was inebriated; and finally did with violence overcome him and practice upon him the shameful and cruel vice of sodomy". He fled following this accusation, for a time residing in Chemnitz before eventually moving on to Prague. Rheticus was then found guilty in his trial in absentia and consequently exiled from Leipzig for 101 years as well as having his possessions impounded. As a result, he would come to lose the support of many long-time benefactors including Melanchthon.

He died on 4 December 1574 at age 60 in Kassa, Slovakia.

Canadian astrologer Jim Birke quotes Dava Sobel's book "A More Perfect Heaven": "in this horoscope for Georg Joachim Rheticus caused his student Nicholas Gugler, who drew the chart, to recalculate the professor's birth time and date" (page 78), "in the very early hours of Feb 16, 1514" (page 79).
