Ursus of Ravenna was a 4th-century bishop who served the city of Ravenna for twenty-six years. Born to a noble pagan family in Sicily, he eventually moved to Ravenna after converting to Christianity, which caused conflict with his relatives. Following the passing of Liberius III, he was elected to his episcopal position. He is primarily remembered for establishing the Ravenna Cathedral, a structure known as the Basilica Ursiana, which was built to honor his leadership.
Life and ministry

After leaving Sicily, Ursus became a prominent figure in the early church of Ravenna. Although historical timelines regarding his specific years in office vary, he is credited with founding the Basilica Ursiana. He died on April 13, which coincided with Easter Sunday in 396, and was interred within the cathedral he had established.
Veneration

Recognized as a saint, Ursus is honored within both the Roman Catholic and Eastern Orthodox traditions. His memory is preserved through an annual feast day observed on April 13. While his original cathedral was later demolished and rebuilt during the 18th century, his legacy remains central to the religious history of the region.
