Peter of Capua
Peter was a member of an Amalfitan family. After a being a teacher at the University of Paris, he was employed by Pope Innocent III as legate. He made trips to Poland and Bohemia in 1197, bringing decision of introducing celibacy. He also served as legate to France from 1198. He made a truce between Richard I of England and Philip II of France, in December 1198. During Peter's meeting with Richard and William Marshal, the northerners found Peter's appearance and obsequious style of diplomacy to be repellent. Peter did succeed in convincing Richard to agree to a conditional five-year truce, but when he persisted in asking that Richard also release Philip of Dreux (a Bishop of Beauvais whom the king intensely hated) Richard lost his temper and threatened to castrate Peter.
