ITHACIUS, or IDACIUS.
THis IDACIUS or ITHACIUS, Surnam'd Clarus, Bishop of Ossobona, a City in the Province of Baetica, was, as we have already said, one of the greatest Enemies of the Pri∣scillianists. * 1.1 St. Isidore of Sevil observes in his Book of Ecclesiastical Writers, That he wrote a Book by way of Apology, against the detestable Doctrines of Priscillian, wherein he discovers the Witchcraft and Infamous Crimes of those Sectaries, and shews, That a certain Magician call'd Mark, a Native of Memphis in Egypt, was the Disciple of Manichaeus and Master of Priscillian. The same Author adds, That this Idacius was depriv'd of the Communion of the Church, together with the Bishop Ursacius, upon the account of the Death of Priscillian, whose Accusers they had been, and that he being sent into Banishment, ended his Days there under the Reign of Theodosius and Valentinian. St. Isidore makes no mention of the Books against Varimadus, which bear the Name of Idacius; and indeed they do not belong to this Author but to Vigilius Tapsensis, as we shall show when we come to speak of Vigilius: This Apologetick of Idacius is lost. St. Isidore observes that it was well written. [Idacius and Ithacius are not two different Names for the same Person as here seems to be implied; for in Sulpitius Severus they are constantly divided.]
