[edit] Life
Kirwitzer was born in Kadaň (Germ. Kaaden) to a protestant family descended from the village of Krbice (Germ. Kürbitz) so his surname was derived from "Kürbitzer". He converted to Catholicism as a youth and started studying Jesuit Academy in Olomouc (after Charles University in Prague the second oldest university in the Czech lands established by Bishop Vilém Prusinovský z Vicíkova). He attracted attention of his professors for his talent especially for natural science. In 1606 he became a novice at Jesuits in Brno. After a short time he was called up to Rome to be embodied in the Collegium Romanum. He was a member of this College in the time when Galileo Galilei was in Rome (1611) to state his case in the question of Heliocentric and Ptolemaic systems. The Roman College was then open to the Copernican opinion held by Galileo. After a short career as a Professor of Mathematics in Gratz Kirwitzer leaves with other 17 brothers for China as a missionary. Their ship San Carlos arrived in Goa, India, in 1618. After several years in Goa he moved to Macao where he died on May 22, 1626. He didn't stop being interested in astronomy, he kept in touch with Johann Adam Schall von Bell, a German Jesuit that was preparing the reform of the Chinese calendar and later became president of the Astronomical Office in Beijing. His observations of comets were published in Observationes cometarum anni 1618 factæ in India Orientali a quibusdam S. J. mathematicis in Sinense regnum navigantibus in Aschaffenburg in 1620.
[edit] Heliocentric opinion
The exact opinions of Wenceslas Pantaleon Kirwitzer on the topic of heliocentric system are dubious. He never wrote about it in China. He was considered Copernican by his contemporaries, though. For further reading on this topic: Copernicus in China
