This paper identifies several indigenous Egyptian attestations of King Nechepsos, previously well known from Classical sources. The name may be understood as ‘Necho the Wise’, and refers to Necho II of the Twenty-sixth Dynasty. His association with astrology may be related to an eclipse near the beginning of that king’s historical reign. This paper further identifies the sage Petosiris known from Greek texts as the well-attested sage Petesis. The divine instructors of Nechepsos and Petosiris are identified as Imhotep and Amenhotep son of Hapu.
