Petosiris was the son of Sishu and Nefer-renpet. He lived in the second half of the 4th century BCE, during the 28th Dynasty. In his tomb, located in the necropolis at Tuna el-Gebel, Petosiris prided himself on having re-established the fortunes of the temples in which he served.
There is a pseudepigraphiconomantic text, Petosiris to Nechepso, and it is possible that the priestly Petosiris described in this article is the inspiration for the attribution of authorship.[3]Nechepso lived in the 7th century BCE and that the text is likely 2nd century BCE.
