"The Egyptians," Diodorus remarks, "are of opinion that the soul of the dead Osiris passed into this bull, and thus continues among them, and will so continue among their descendants." Plutarch says that the Apis at Memphis was an image of the soul of Osiris. According to the usual account of the priests, Osiris and Apis were one; for they taught that the Apis was to be regarded as a fair image of the soul of Osiris. Strabo tells us, "The bull Apis, which is revered as a god, is the same as Osiris. The temple in which the Apis was kept stands beside the temple of Hephæstus (Ptah). There is also a temple of Serapis in that city, before which we saw sphinxes, buried in the sand, some to the middle, some to the neck."[98] Evidence from other sources, no less than the monuments, confirms these accounts of Diodorus and Plutarch. The monuments exhibit the Apis with the sun's disk and the royal serpent between his horns, and Greek papyri tell us that the keeper with whom the Apis was placed was known as the "Herdman of Osorapi," _i.e._ of Osiris-Apis (Osarhapi).[99] We may assume that this Osorapi was the Serapis or Sarapis of the Greeks, and the temple of Serapis a temple of Osorapi. The sphinxes buried in sand at Memphis have been discovered on the plateau on which the inhabitants buried their dead to the west of the ruins of this city. They are found here in two rows as often before the entrance of temples between Abusir and Sakkarah. It is by following this path of sphinxes that the discoverers were recently enabled to find the ruins of the temple of Serapis, _i.e._ the temple of the grave of Osiris-Apis, and the sepulchral chambers of the Apis-bulls hewn in the rocks around it. The oldest of the tombs hitherto opened belongs, according to the inscriptions, to an Apis buried in the time of Amenophis III. (1524-1488 B.C.). Above ground rises a massive structure, truncated at the top, and decorated with reliefs. This is the mortuary chapel. A sloping passage, the entrance to which lies before this structure, leads beneath the earth to a sepulchral chamber, where stands a sarcophagus with the mummy of the Apis. The relief on the structure above exhibits the king bringing a drink-offering to the Apis. Beside the picture of the bull we read, "The living Osiris, the lord of the sky: he is Tum (p. 51): his feathers are upon him: he gives life for evermore." On the sarcophagus of an Apis buried in a similar tomb in the reign of Horus (1455-1443 B.C.), we read:--"Apis-Osiris, the great deity who dwells in Amenti, the ever-living lord." King Ramses II. (1388-1322 B.C.), in the second half of his reign, caused a broad gallery to be excavated under the rock, on both sides of which chambers of about twenty feet high were subsequently cut out as occasion required; in these were placed the remains of the dead Apis-bulls in sarcophagi of basalt or granite. When the gallery of Ramses was no longer sufficient, Psammetichus I.
