Not only were various animals held sacred, as being the emblems of certain deities, but some were thought to be real gods. Thus the soul of Osiris, it was imagined, animated the body of some bull, which might be known from certain spots and markings. Upon the death of the sacred bull, or Apis, as he was called, a great search, accompanied with loud lamentation, was made throughout the land for his successor: for, the moment the soul of Osiris departed from the dying bull, it entered a calf that moment born. The calf was always found with the proper markings; but, as Wilkinson says, the young animal had probably been put to "much inconvenience and pain to make the marks and hair conform to his description." The body of the deceased Apis was carefully embalmed, and, amid funeral ceremonies of great expense and magnificence, deposited in the tomb of his predecessors. In 1851, Mariette discovered this sepulchral chamber of the sacred bulls. It is a narrow gallery, two thousand feet in length, cut in the limestone cliffs just opposite the site of ancient Memphis. A large number of the immense granite coffins, fifteen feet long and eight wide and high, have been brought to light. Many explanations have been given to account for the existence of such a debased form of worship among so cultured a people as were the ancient Egyptians. Probably the sacred animals in the later worship represent an earlier stage of the Egyptian religion, just as many superstitious beliefs and observances among ourselves are simply survivals from earlier and ruder times. JUDGMENT OF THE DEAD.--Death was a great equalizer among the Egyptians. King and peasant alike must stand before the judgment-seat of Osiris and his forty-two assessors. This judgment of the soul in the other world was prefigured by a peculiar ordeal to which the body was subjected here. Between each chief city and the burial-place on the western edge of the valley was a sacred lake, across which the body was borne in a barge. But, before admittance to the boat, it must pass the ordeal called "the judgment of the dead." This was a trial before a tribunal of forty-two judges, assembled upon the shore of the lake. Any person could bring accusations against the deceased, false charges being guarded against by the most dreadful penalties. If it appeared that the life of the deceased had been evil, passage to the boat was denied; and the body was either carried home in dishonor, or, in case of the poor who could not afford to care for the mummy, was interred on the shores of the lake. Many mummies of those refused admission to the tombs of their fathers have been dug up along these "Stygian banks."
