Jerome of Prague (Jeroným Pražský in Czech, 1379 – 30 May 1416) was a Czech scholastic philosopher, theologian, reformer, and professor. Jerome was one of the chief followers of Jan Hus and was burned for heresy at the Council of Constance. He is often called Hieronymus the Latin form of his first name.
Jerome was born in Prague, Bohemia (now the Czech Republic) in 1379 and graduated from the University of Prague in 1398. He later studied at Oxford University where he first became familiar with the reformist teachings of John Wycliffe. He was a philosopher, theologian, university professor, and church reformer who dedicated his life to eradicate those church doctrines and dogmas he found to be corrupt. He was constantly in and out of jail. His radical ideas eventually brought about his death by execution as a heretic to the church, but made him a martyr for the Protestant Reformation and followers of Jan Hus (known as Hussites).
He was well-educated and spent most of his life traveling, trying to incite religious reform in various cities. It was for his criticisms rather than heresy that he was martyred.
Jerome spent time teaching at the universities of Paris, Cologne, and Heidelberg, but was accused of heresy at all these universities and forced to return to Bohemia. He spent much of his life traveling about various universities, but frequently returned to Bohemia where he was virtually safe from any prosecution. He earned popular renown, as his rhetoric and oratory skills were acclaimed and often roused the public into demonstrations against the church, although they sometimes ended badly. He secured, in 1399, permission to travel. In 1401 he returned to Prague, but in 1402 visited England, where, at Oxford University, he copied out the Dialogus and Trialogus of John Wyclif, and thus evinced his interest in Lollardry. He became an ardent and outspoken advocate of realism and, thereafter, of Wyclifism; charges of which were constantly getting him into trouble. In 1403 he went to Jerusalem, in 1405 to Paris. There he took his master's degree, but Jean Gerson drove him out. In 1406 he took the same degree at the University of Cologne, and a little later at the University of Heidelberg.
