ABSTRACT
These two treatises, On the Holy and Vivifying Trinity and On the Inhumanation of the Lord, written before the council of Ephesus,1
survived under the name of Cyril of Alexandria in a Vatican manuscript (Vat. gr. 841). Cardinal Angelo Mai discovered and published them in the nineteenth century under the name of Theodoret’s one-time opponent, and they were reprinted in Migne’s PG in this way.2 In 1888 Albert Ehrhard proved that they were in fact composed by Theodoret.3
