In 1501, two papal bulls were issued concerning the child, Giovanni Borgia. In the first, he was recognized as Cesare's child from an affair before his marriage. The second, contradictory, bull recognized him as the son of Pope Alexander VI. Lucrezia's name is not mentioned in either, and rumors that she was his mother have never been proven. The second bull was kept secret for many years, and Giovanni was assumed to be Cesare's son. This is supported by the fact that in 1502 he became Duke of Camerino, one of Cesare's recent conquests, hence the natural inheritance of the Duke of Romagna's oldest son. Giovanni went to stay with Lucrezia in Ferrara after Alexander's death, where he was accepted as her half-brother.
