Theodorus (64) Lector, reader of the church of Constantinople. He composed in two books a tripartite history out of Socrates, Sozomen, and Theodoret, extant in MS. at Venice. It was copied by Leo Allatius, but not published. Valesius used his MS. in his edition of those authors. He also composed a history which extends from the last days of Theodosius the younger to the reign of the elder Justin, A.D. 518; some portions of which remain, and are in Migne's Patr. Gk. lxxxvi. col. 157–2280. They have been collected out of Nicephorus Callistus, John of Damascus, and the fifth action of the seventh general council. His history abounds with wonderful stories in defence of orthodoxy. He tells that Timotheus, bp. of Constantinople, A.D. 571, was the first to ordain the recitation of the Nicene Creed at all celebrations of the Holy Communion. It was previously only recited once a year, at the end of Lent. Evidently the Arian party must have been still strong at Constantinople in cent. vi. A question has been raised whether our Theodore did not live in cent. viii. rather than cent. vi. Combefis in his Originum Rerumque Constant. Manip. and Baudurius in his Imper. Orient. have given some quotations from a Theodorus Lector relating to the statues with which Constantinople was adorned, one containing an incident which proves the writer to have lived in the reign of Philip, 711–713 (Combef. p. 11; Baud. p. 88); but two men of the same name may have occupied the same office.
