Johannes Vogelin

from Wikipedia, the free encyclopedia

Johannes Vögelin (* before 1500 in Heilbronn , † 1549 in Vienna ) was professor of mathematics and astronomy in Vienna.

Life

He enrolled at the University of Heidelberg in 1505 , was a bachelor's degree in 1506 and a master's degree in 1508. In 1516 he was schoolmaster at the cathedral school in Augsburg , later cathedral preacher. In 1525 he came as a mathematics teacher at the St. Stephen's School in Vienna, and in 1528 - as the successor to Georg Tannstetter - he became professor of mathematics, astronomy, astrology and geography at the University of Vienna . In 1537 he was named in the second reform law of King Ferdinand I concerning the University of Vienna : next to the Primus Mathematicus(that was the one who had to teach mathematics in the narrower sense, namely arithmetic, geometry and music): “the other mathematicus (for which the birds are ordained)” - he was supposed to teach primarily astronomy, but also geography and astrology. He is considered the last representative of the second Viennese school of mathematicians and astronomers.

He wrote in 1528 that later repeatedly launched mathematics textbook elementals geometricum ex Euclidis Geometria ... , 1529 an annotated edition of the Spheres of Theodosius . He was also the author of several writings on celestial science and especially comets (1532). In it he discussed - on the occasion of the comet's appearance in 1532 - the question of what a comet actually is. He named three traditional views ("I find three excellent opinions about the origin of comets through diligent reading of the ancients."): First, the meteorological (according to Aristotle : comets as earthly evaporation), second, the astronomical (according to Seneca : comets as only planet-like celestial bodies visible at times), and thirdly the theological (according to Johannes Damascenus : comets as warning signs created by God only for a certain time) (on pages A1v – 2v). Vogelin agreed with the third view; he had logical and empirical objections to the other two views, and in the third view the characteristics of the comet and various earthly events coincided with a saying from the Apocalypse of John . From this, Vogelin concluded that the time for the judgment of the whore Babylon - in which he saw the Turkish power - was imminent (page B3r-4r).

Vögelin's research and observations were taken up by Thaddaeus Hagecius and Tycho Brahe , among others . Sebastian Solidus wrote a funeral delegation for him after Vogelin's death.
