Guibe, Robert a French cardinal, was born at vitre, being of high parentage, which contributed to his early fortune. His ambition as well as his aptitude to conduct the most difficult affairs, rendered him one of the most remarkable men of his time. Being appointed bishop of Treguier in 1483, he obtained his bulla on May 20, but not yet having attained the age requisite to a canon, the pope intrusted the government of the diocese to a provisional administrator. In February 1485, Guibe went to Rome on a message from duke Francis. In 1499 he returned to Brittany, to be transferred from the see of Treguier to that of Rennes. He went to Rome a second time in 1502, and was appointed cardinal by Julius II, with the title of St. Anastasia, January 1, 1506. On January 24, 1507, he was called to the episcopal see of Nantes, but, preferring his position at Rome, he did not remain long at his new church. He was legate of Avignon in 1511. The king afterwards took away the revenues of the benefices from the cardinal, and Guibe resigned the bishopric of Nantes in favor of FranCois Hamon, his nephew. Finally, in 1512, he assisted at the Lateran Council, and died September 9, 1513. See Hoefer, Nouv. Biog. Generale, s.v.
