Petosiris, called Ankhefenkhons, was the high priest of Thoth at Hermopolis and held various priestly degrees in the service of Sakhmet, Khnum, Amen-Re and Hathor. The son of Sishu and Nefer-renpet, he lived in the second half of the 4th century BCE under Persian rule. In his tomb inscriptions (his tomb is in the necropolis at Tuna el-Gebel) he prided himself on having restored the fortunes of the temples in which he served.
There is a pseudepigraphic onomantic text, Petosiris to Nechepso, and it is possible that the priestly Petosiris described in this article is the inspiration for the attribution of authorship. Nechepso lived in the 7th century BCE and that the text is likely 2nd century BCE.
