All that remains are an eyewitness description of the ceremonies in 1455 in which Calixtus III
enrolled Vincent Ferret in the catalogue of saints and the bull of canonization issued by Calixtus's successor, Plus II, in 1458.
He preached the crusade bull of Calixtus III
in his home town of Palencia in 1457 and wrote his Fortalitium Fidei, against all the enemies of the Church, from about 1459 to 1461.
Alonso Borgia (1385 - 1458) Became Pope Calixtus III
in 1455 and laid the foundation of his family ' s power and influence in Italy.
THE notorious Borgia family produced two Popes - Calixtus III
(1455-1458) and Alexander VI (1492-1503).
This time such papal intervention would be crucial; yet the pope, Calixtus III
Borgia, from Valencia, a close associate of Alfonso V, ignored his predecessors' acceptance of Ferrante as heir to the throne and obstinately refused to accept him as King of Naples, planning, so rumour insisted, to proclaim one of his own nephews as ruler instead.
