during the reign of Shebitku. This detail in itself is sufficient to show that the reign of Shabaka cannot precede that of Shebitku. The construction of the tomb of Shebitku (Ku. 18) resembles that of Piye (Ku. 17) while that of Shabaka (Ku. 15) is similar to that of Taharqa (Nu. 1) and Tantamani (Ku. 16). One of the strongest evidence that Shabaka ruled after Shebitku was demonstrated by the architectural features of the Kushite royal pyramids in El Kurru. Only in the pyramids of Piye (Ku 17) and Shebitku (Ku 18) are the burial-chambers open-cut structures with a corbelled roof, whereas fully tunneled burial chamber substructures are found in the pyramids of Shabaka (Ku 15), Taharqa (Nu 1) and Tantamani (Ku 16), as well as with all subsequent royal pyramids in El Kurru and Nuri. The fully tunneled and once-decorated burial chamber of Shabaka's pyramid was clearly an architectural improvement since it was followed by Taharqa and all his successors. The pyramid design evidence also shows that Shabaka must have ruled after—and not before—Shebitku. This also favours a Shebitku-Shabaka succession in the 25th dynasty. In the Cairo CG 42204 of the High Priest of Amun, Haremakhet—son of Shabaka—calls himself as "king’s son of Shabaka, justified, who loves him, Sole Confidant of king Taharqa, justified, Director of the palace of the king of Upper and Lower Egypt Tanutamun/Tantamani, may he live for ever." However, as first noted by Baker, no mention of Haremakhet's service under Shebitku is made; even if Haremakhet was only a youth under Shebitku, this king's absence is strange since the intent of the statue's text was to render a chronological sequence of kings who reigned during Haremakhet's life, each of their names being accompanied by a reference to the relationship that existed between the king mentioned and Haremakhet. A possible explanation for Shebitku's omission from the statue of Haremakhet was that Shebitku was already dead when Haremaket was born under Shabaka. Payraudeau notes that Shebitku’s shabtis are small (about 10 cm) and have a very brief inscription with only the king's birth name in a cartouche preceded by “the Osiris, king of Upper and Lower Egypt” and followed by mȝʿ-ḫrw. They are thus very close to those of Piye/Piankhy [42 – D. Dunham, (see footnote 39), plate 44.]. However, Shabaka's shabtis are larger (about 15–20 cm) with more developed inscriptions, including the quotation from the Book
