Agathodaimon

Agathodaimon is known only as the recipient of four short letters from Isidore of Pelusium (c. 360-c. 435 AD), the ascetic and biblical commentator whose vast correspondence touches hundreds of named addressees across late-antique Egypt. Nothing certain is recorded of his life, office, or dates beyond this epistolary attestation; the Greek name ("good spirit/fortune") was common in Egypt and gives no further identification. Based on Isidore's milieu, he was most plausibly a cleric, monk, or local correspondent active in the Pelusium region of the Nile Delta in the early fifth century, but this is an inference from context rather than independently documented fact.
