Adeodatus I (also called
Deusdedit I) served as
Pope from
615 to

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.
