a son of the notary Theodorus, who, with others, was put to death by the emperor Valens at Antioch A. D. 371, for seeking by magical arts to ascertain who was to be the successor of that emperor.
He appears to have been a pagan; a man of suspicious temper, and easily led by others into acts to which probably his own disposition would not have prompted him. When he entered upon his office, A. D. 384, Antioch was suffering from a severe famine, and he made matters worse by threats against the bakers, in order to induce them to sell at a fixed price, an arbitrary proceeding which induced them to take to flight.
The sophist Libanius, to whom Icarius had shown great respect as to a father, induced him to recal his threats; but Icarius soon reverted to his arbitrary proceedings. Libanius addressed three Orations to Icarius, one hortatory, the others invectives. The second invective is not given in the edition of the works of Libanius by Morell (2 vols. fol. Paris, 1606-1627), but was first published in the edition of Reiske, 4 vols. 8vo. Altenburg, 1791-97.
