THIRD CENTURY. Egyptian bishop. He is associated with Phileas, Theodorus, and Pachumis in addressing a letter to Melitius of Lycopolis. The letter, a Latin version of which is still extant, remonstrates with Melitius on his irregular ordinations. The bishops were in prison when the letter was written and were martyred under Galerius. This Hesychius is usually identified with the reviser of the text of the Septuagint and NT, or at least of the gospels, which was extensively used in Egypt. Jerome refers to it more than once, charging Hesychius with making apocryphal additions to the text, a charge that is later repeated in the Gelasian Decree.
