Didumos

Didymus (Didumos) is otherwise little attested and is known chiefly as a correspondent of Isidore of Pelusium (c. 360-c. 450 AD), the prolific ascetic and priest of Pelusium in the northeastern Nile Delta whose surviving corpus of roughly 2,000 short letters preserves the names of many minor officials, clergy, and laymen who would otherwise be unknown. He is addressed in the letters with the title scholasticus, indicating an advocate, jurist, or man of legal learning, and was most likely active in the region of Pelusium or the wider eastern Egyptian Delta during the first half of the fifth century AD. Nothing further about his life, career, or dates can be established with confidence beyond what Isidore's six letters to him imply.
