present in Naples in December 1294 and witnessed many of the events of the abdication and election, said that Benedetto Caetani was only one of several cardinals who pressured Celestine to abdicate. However, it is also on record that Celestine V abdicated by his own design after consultation with experts, and that Benedetto merely showed that it was allowed by Church law. Either way, Celestine V vacated the throne and Benedetto Caetani was elected in his place as pope, taking the name Boniface VIII. The regulations promulgated in the 1274 papal bull Ubi periculum had not envisioned an abdication, but declared that election proceedings should begin ten days after the death of the incumbent. The 1294 papal conclave accordingly began on 23 December, ten days after Celestine's abdication. This gave all twenty-two cardinals the chance to assemble at the Castel Nuovo in Naples, the site of the abdication. Hugh Aycelin presided over the papal conclave as the senior cardinal bishop. Benedetto Caetani was elected by ballot and accession on Christmas Eve, 24 December 1294, taking the name Boniface VIII. On the first (secret) ballot, he had a majority of the votes, and at the accessio a sufficient number joined his majority to form the required two-thirds. He was consecrated bishop of Rome in Rome by Cardinal Hugh Aycelin on 23 January 1295. He immediately returned the Papal Curia to Rome, where he was crowned at the Vatican Basilica on Sunday, 23 January 1295. One of his first acts as pontiff was to imprison his predecessor in the Castle of Fumone in Ferentino, where he died on 19 May 1296 at the age of 81. In 1300, Boniface VIII formalized the custom of the Roman Jubilee, which afterwards became a source of both profit and scandal to the church. Boniface VIII founded Sapienza University of Rome in 1303. Canon law In the field of canon law Boniface VIII had considerable influence. Earlier collections of canon law had been codified in the Decretales Gregorii IX, published under the authority of Pope Gregory IX in 1234, but in the succeeding sixty years, numerous legal decisions were made by one pope after another. By Boniface's time a new and expanded edition was needed. In 1298 Boniface ordered published as a sixth part (or Book) these various papal decisions, including some 88 of his own legal decisions, as well as a collection of legal principles
