Pope Adeodatus I

Adeodatus I (also called Deusdedit I) (died November 8, 618) served as Pope from 615 to 618. He was born in Rome, the son of a subdeacon. According to tradition, he was the first pope to use lead seals (bullae) on papal documents, which in time came to be called "papal bulls".

According to tradition, Adeodatus was a Benedictine monk, but there is no certain evidence for this.
