Peter the Hermit, a monk, born in Amiens, of good family, who is credited with having by his preaching kindled the enthusiasm in Europe which led to the first Crusade; he joined it himself as the leader of an untrained rabble, but made a poor figure at the siege of Antioch, where he was with difficulty prevented from deserting the camp; he afterwards founded a monastery near Liège, where he died (1050-1115).
