Papyrus Lips. Inv. 590 contains the remains of an Egyptian king-list of the Late Period. Although it is highly fragmentary and its interpretation is difficult, a short sequence of kings plays a catalytic role in identifying some pharaohs in Manetho’s and Diodorus’ works. Furthermore, it is now possible to rehabilitate Diodorus’ Egyptian chronology in one aspect, and to explain some obvious discrepancies in Herodotus’ historical framework: Ammeris the Nubian is Kashta, Marrhos is Amenhotep III, and Moiris is an amalgam of Amenemhet III, Amenhotep III and Kashta.
