Le De Trinitate du Pseudo-Didyme et le culte des archanges : un élément méconnu de datation

Pseudo-Didymus’ De Trinitate mentions many sanctuaries of the archangels Michael and Gabriel, finely adorned, some of which were quite famous to attract people from very far in the hope of a miracle. Although this testimony was usually considered as an ancient evidence because of its purported attribution to Didymus the Blind, it does not actually reflect the state of the archangels’ cult in the fourth century. However, it proves to be an important element for the dating of the De Trinitate itself, since it refers to a time when the cult of the archangels was developed in the East. The documentary and literary evidence shows that the churches dedicated to them, especially to Saint Michael, significantly multiply in the sixth century, and that their cult is being established under the reign of Justinian (527-565). It is from this period that the composition of Pseudo-Didymus’ De Trinitate is likely to date.
