Pope Boniface IV, OSB was the bishop of Rome from 608 to his death. Boniface had served as a deacon under Pope Gregory I, and like his mentor, he ran the Lateran Palace as a monastery. As pope, he encouraged monasticism. With imperial permission, he converted the Pantheon into a church. In 610, he conferred with Bishop Mellitus of London regarding the needs of the English Church. He is venerated as a saint in the Catholic Church with a universal feast day on 8 May.

The Pantheon is a former Roman temple and, since AD 609, a Catholic church in Rome, Italy. It was built on the site of an earlier temple commissioned by Marcus Agrippa during the reign of Augustus, then after that burnt down, the present building was ordered by the emperor Hadrian and probably dedicated c. AD 126. Its date of construction is uncertain, because Hadrian chose not to inscribe the new temple but rather to retain the inscription of Agrippa's older temple.
