The stelae dedicated to Apis in the Serapeum at Saqqara, commissioned by the reigning monarch, represent a key element in understanding the events of this period. As in the Late Period, the catacombs in which the remains of the sacred bulls were buried gradually grew in size, and later took on a monumental appearance that confirms the growth of the cult's hypostases throughout the country, and particularly in Memphis and its necropolis. Thus, a monument dedicated by Cambyses II seems to refute the testimony of Herodotus, who lends the conquerors a criminal attitude of disrespect against the sacred traditions.
