Licinius was co-emperor with Constantine the Great. At his accession, he had agreed to tolerate Christianity in his territories, but soon turned to persecuting the Christians, and to a variety of carnal sins. He conceived a passion for Glaphyra, a Christian virgin handmaid of the Empress Constantia. When Glaphyra told Constantia of this, the Empress sent her away to Amasia in the East for her protection. There she was received and protected by Bishop Basil of that city. Licinius learned where Glaphyra was hiding and ordered that both she and the bishop be brought to him as prisoners. The soldiers who came for her found that she had already died, so they returned with only Bishop Basil, who was subjected to cruel tortures, then beheaded. His body was cast into the sea, but, with the help of an angel of God, his people found his body, retrieved it from the sea, and returned it to Amasia.

The Prologue adds, "The Emperor Constantine raised an army against Licinius, overcame him, arrested him and sent him into exile in Gaul, where he ended his God-hating days."
