SABINIANUS, pope from 604 to 606, successor of St Gregory the Great. He incurred unpopularity by his unseasonable economies. The erudite Italian Augustinian Onofrio Panvinio (1529–1568) in his Epitome pontificum Romanorum (Venice, 1557) attributes to this pope the introduction of the custom of ringing bells at the canonical hours and for the celebration of the Eucharist.
