VITTORE IV, ANTIPOPE. — Elected by the partisans of the antipope Anacletus II (q.v.) around the middle of March 1138, he was mockingly surnamed by the Romans "carnecorium" or "carnicorum."
His name was Gregory (membership in the Conti family is unproven), and he had been created cardinal priest of the Holy Apostles by Calixtus II in December 1122. In 1130 he was one of the electors of Anacletus II. No documents are known to have been issued during his very brief antipope reign, which ended on 29 May 1138 through the intervention of St. Bernard, who accompanied him and his partisans to the feet of Innocent II (q.v.) (cf. Ep. 317 of St. Bernard: PL 182, 523). Innocent granted all the requested forgiveness for their promises to uphold V. IV and the other cardinals in their dignity, but at the Second Lateran Council (April 1139) he deposed him along with all the other Anacletians, provoking the protests of St. Bernard, who had advocated reconciliation (cf. Ep. 213: PL 182, 378). After this, nothing more is known of Cardinal Gregory.
