 If Sheshi is to be equated with Salitis, then the seals of Sheshi discovered in Nubia suggest that the Hyksos allied themselves with the Nubians against the native Egyptian 13th Dynasty as soon as they arrived in the Nile Delta, an event which Grimal places at c. 1720 BC.Grimal envisions Sheshi's kingdom as comprising the entire Nile Delta and the Nile valley north of Gebelein.According to Manetho as reported by Josephus in "Against Apion", Salitis reigned from Memphis, and fortified the existing town of Avaris, which was to become the Hyksos' seat of power.
