Sisinnius was a Syrian-born bishop of Rome who served as pope for twenty days in early 708. Although his early life remains largely unknown, he was recognized for his moral integrity and his dedication to the Roman people. His brief tenure began on January 15, 708, following a period of waiting for confirmation from the Exarch of Ravenna. Despite suffering from severe gout that left him physically weakened, he attempted to address both ecclesiastical and civic needs during his short time in office.
