the first writer to formulate justification of genocide. Falkenberg also published Satira in 1412, further attacking the Poles and King Jogaila. At this time King Jogaila was Christian, as was Lithuania. Falkenberg called King Jogaila a "mad dog," unworthy to be king. In a later work Tres tractatuli, published in 1416 Falkenberg attempted to refute Jean Gerson, Pierre d'Ailly, and other doctors of the University of Paris, who had condemned the works of Jean Petit. In this work, moreover, he denied the bishops the right to declare his book or any part of it heretical, claiming that in matters of faith the pope and general councils alone are infallible. By order of Nicolaus, Archbishop of Gniezno, Falkenberg was imprisoned. The Poles demanded the conviction of Falkenberg for heresy, but in vain. His works were condemned by the Council of Constance as scandalously libelous, but not heretical. A similar verdict was given by the Dominican Order, assembled at Strasbourg from May to June 1417, which also condemned the author to life imprisonment. On his return to Rome, Pope Martin V took Falkenberg with him, and kept him for several years in close confinement. Whether he eventually regained his liberty or died there is uncertain.
