so called from the place of his birth, in Bohemia. He was neither a monk nor clergyman, but had a learned education. Having embraced the opinions of John Hus, he began to propagate them in the year 1480. In the mean time the council of Nice kept a watchful eye over him, and considering him as a dangerous person, cited him to appear before them and give an account of his faith. In obedience to this citation, he went to Constance; but on his arrival, in 1415, finding Hus in prison, he set out for his own country. Being seized however on the way, imprisoned, and examined, he was so intimidated, that he retracted, and pretended to approve of the condemnation of Wickliff's and Hus's opinions; but on the 26th of May 1416, he condemned that recantation in these terms: "I am not ashamed to confess here publicly my weakness. Yes, with horror I confess my base cowardice. It was only the dread of the punishment by fire which drew me to confess, against my conscience, to the condemnation of the doctrine of Wickliff and Hus." Accordingly sentence was passed on him; in pursuance of which he was delivered to the secular arm, and burnt in 1416. He was a person of great parts, learning, and elocution.
