Their story
Ulpian was a young Christian of Tyre. Encouraged by the example of St Apian and other martyrs at Caesarea, he boldly confessed Christ before the cruel judge Urbanus.
The governor had him scourged and then racked until his joints were dislocated and his bones broken. He was then sewn into a leather bag with a dog and an asp, carried to the shore on a cart drawn by black bulls, and thrown into the sea. Butler's source is Eusebius (bishop of Caesarea, d. c. 339, the first historian of the Church), On the Martyrs of Palestine, chapter 5.
