Excommunication
Around this time Bohemond left his wife Theodora, a niece of the recently-deceased Emperor Manuel, and married a woman named Sibylla, "who had the reputation of practicing evil arts" according to William of Tyre. He was excommunicated by Pope Alexander III, and Antioch was placed under an interdict, but "to this...he paid slight attention. On the contrary, he continued on his wicked course with redoubled energy." He imprisoned Patriarch Aimery and other bishops and looted their churches. Opposition to Bohemond was led by Reynald Masoir. Patriarch Heraclius of Jerusalem was sent to mediate in 1181, with Raynald of Châtillon, Raymond III of Tripoli, Arnold of Torroja, and Roger des Moulins, but Bohemond refused to acquiesce, and expelled the mediators as well as a number of his own nobles.
