Description: (Bishop of Rome)
Pope Adeodatus I was the bishop of Rome from 19 October 615 until his passing. He was the first priest elected as pope in over 80 years. During his papacy, he introduced the use of lead seals or bullae on papal documents, a practice that became a standard in official papal communications. His contributions to the administrative aspects of the papacy left a lasting impact, and he is commemorated annually on 8 November as his feast day.
