c.1390-1433. Hussite martyr. Probably born in Kravare in Moravia, he studied medicine at Montpellier, then entered the University of Paris (M.A., 1415). He then returned to Prague where he taught medicine, becoming about 1421 physician to Wladislaw Jagiello, king of Poland. By this time he had become a radical Hussite, writing two books against the papacy: Sermones de Antichristi and De Anatomia Antichristi. After ten years in the service of the Polish king, he returned to Prague, perhaps as a result of persecution for his religious beliefs. He then left, possibly having met Scots traders in Poland, to work with the Lollards* in Scotland. He was arrested, however, and burned at the stake in St. Andrews.
