that no allusion is made to the refutation of the twelve chapters; to the defence of Diodorus of Tarsus and Theodorus of Mopsuestia, nor to the Dialogues, though all are held to have been written before the Latrocinium. It may have been, as Garnerius conjectures, that Theodoret did not judge it politic at this time to call attention to these particular works, but the assumption is not based on strong grounds, and Theodoret never appears as one unwilling to avow his convictions, which indeed, were perfectly well known.
Gennadius, presbyter of Marseilles, who died in 496, writes "Theodoretus, bishop of Cyrus, is said to have written many works: those, however, which have come to my knowledge are the following; of the Incarnation of the Lord, against the presbyter Eutyches, and Dioscorus, bishop of Alexandria, who deny that there was in Christ human flesh, -- powerful writings wherein he proves, as well by argument as by scriptural evidence, that Christ had very flesh of the substance of His mother, which He took from the Virgin, and very Godhead, which by eternal generation He received, in being generated, from God the father begetting Him. There exist also his books of Ecclesiastical History, which he wrote in imitation of Eusebius of Cæsarea, beginning from the end of the books of Eusebius down to his own time, viz.: from the twentieth year of Constantine down to the reign of Leo I, in whose reign he died." 
Photius, in the ninth century, says that he has read the Ecclesiastical History; twenty-seven books against Heresies, among which he reckons the "Eranistes;" five books "Hæreticarum Fabularum;" five in praise of Chrysostom; with Commentaries on Daniel, the Octateuch, Kings, Chronicles, and the Twelve Minor Prophets.
Nicephorus Callistus Xanthopulus in the fourteenth century, Hist. Ecc. xiv.54, writes: "Theodoretus, Syrian by birth, was a follower of the great Chrysostom, whom he set before him as a model of style. His own was flowing and copious, eloquent and easy, and not destitute of Attic grace." He mentions expositions of difficult passages of the Old Testament; Commentaries on the Prophets and the Psalms; the "de Providentia;" a volume "On the Apostles;" the Confutation of heresies, called "the battle between truth and falsehood;" the refutation of Cyril's "Twelve Chapters;" the Ecclesiastical History; the "Philotheus," a History of the Lovers of God; three books on the divine doctrines, and five hundred (?) letters.
The following is the catalogue of extant works as given by Sirmondus and followed by Garnerius.

 Cf. Garnerius in Migne's Theodoret V. 255.  The last record in the History appears to be of a.d. 440, cf. p. 159. Eusebius ends, and Theodoret begins, with the defeat of Licinius in 323. Constantine began to reign in 306.  A writer, supposed to be a layman, whose works were discovered in two mss. at the end of the seventeenth century. One is in the Vatican, the other was found in the Cathedral Library of Beauvais. Marius wrote fully on the Nestorian Controversy, and with acrimony against Theodoret.
