From the Prologue of Ochrid
Brothers by birth, sons of a certain Prince Vitalius in southern Italy. Admirable in nobility, mighty in faith. They were tried for their faith in Christ, led from one judge to another, from one torturer to another. They were taken to Sicily and killed there, in the time of Emperor Licinius. Alphaeus had his tongue cut out. From the flow of blood Alphaeus died. Philadelphus was burned on an iron grate, and Cyrinus in fire. Their incorrupt relics were found in 1517. These three brothers appeared to Saint Euthalia.
