Vicinius of Sarsina was a fourth-century bishop from Liguria who served as the first leader of the church in Sarsina. Before his election, he lived as a hermit on a nearby mountain, practicing prayer and penance. He was chosen for the episcopacy around 303 following a divine sign, and he held the position until his death in 330. Throughout his life, he was known for his spiritual discipline, often returning to solitary mountain retreats even after becoming a bishop.
