Pictured is the sarcophagus of Saint Vitale in the Church of the Saints Vitale and Agricola in the Basilica of Saint Stephen in Bologna, Italy. Agricola was a Christian citizen of Bologna who converted his slave Vitale to Christianity. They became deeply attached to each other. Vitale was the first to suffer martyrdom, being executed in the amphitheatre. Authorities then tortured Agricola, but failed to make him give up his religion. He was finally crucified. They were the promartyrs of Bologna, considered to have died about 304 during the persecution ordered by the Roman Emperor Diocletian.
