Gregorius (Γρηόριος) Argentinus, or St. Gregory of Agrigentum, a Greek theologian, was born near Agrigentumn about A.D. 524. Destined for the priesthood by his pious parents, he studied at Jerusalem for five years, and was there ordained deacon. 'Thence he went to Antioch and, Constantinople,' and gained high repute both places for learning, eloquence, and sanctity. From Constantinople he went to Rome, ands the; pope named him bishop of Agrigentum in Sicily. Two disappointed aspirants for the see hired a prostitute to charge him with fornications. He went to Constantinople, and was pronounced innocent by Justinian. Returning to Agrigentum, he cried there, November 23, 562. He wrote Orationes and Conciones; also a Commentarius in Ecclesiasten. This last is lost; the others are given in the life of Gregory, by Leontius, to be found in Cajetanus, Sancti Siculi, volume 1. — Hoefer, Nouv. Biog. Generale, 21:856; Cave, Hist.
