Abstract
Traditionally attributed to Didymus the Blind, this anonymous work on the Trinity found in the Cod. Rom. Angel. gr. 116, has no certain authorship. The article throws light on the numerous parallels among the so-called De Trinitate and passages from Basil, the two Gregorys, Athanasius, the pseudo-Basilian books IV and V of the Adversus Eunomium, as well as from some writings of Cyril of Alexandria. Even though the question of the paternity of De Trinitate is still destined to remain clouded, the parallels pointed out by the Author tend definitely to exclude Didymus as the author of this anonymous theological tract.
