This saint figures in the Acta of SS. Julian of Antioch and Companions collected in the Acta Sanctorum for January 9. In the story twenty soldiers in Antioch and the son of the Prefect are imprisoned for accepting Christianity. Seven Christian brothers then lead the priest Anthony into the prison so that the converts can be baptized. For this Anthony has his eyes pulled out with hooks, and all of them are put to the sword.1
