Résumé :
The present study, after a quick codicological investigation of the two surviving manuscripts of the De trinitate by pseudo-Didymus, in which it is concluded that one is a copy of the other, focuses on the lexical analysis of the first book of the mutilated trinitarian treatise. By showing divergences from the authentic works of Didymus, alongside parallels with the writings of the Cappadocian Fathers, Cyril of Alexandria, Theodoret, of other late patristic authors, as well as with those of the Neoplatonic philosophers, in particular Proclus, the author concludes that the chronological position of De trinitate should not be before the end of the 5th century, and suggests a possible origin from an environment of Antiochene influence.
