Anti-Pope Callistus III

Also known as

  • Giovanni of Struma


Abbot of Struma. In opposition to Pope Alexander III, in 1168 Giovanni was elected at Viterbo, Italy to succeed anti-pope Guido of Crema. Threatened by the people of Viterbo, he fled to Albano, Italy where he was attacked by the troops of Archbishop Christian de Buch. From Albano, in 1178 he fled to Tusculum where he prostrated himself before Pope Alexander on 29 August; the pope forgave him and later appointed him governor of Benevento, Italy.
