The Serapeum of Saqqara

The Serapeum of Saqqara is a serapeum located north west of the Pyramid of Djoser at Saqqara, a necropolis near Memphis in Lower Egypt. It was a burial place of Apis bullssacred bulls that were incarnations of the ancient Egyptian deity Ptah. It was believed that the bulls became immortal after death. The conventional belief is that the construction occurred circa 1350 BCE. A second gallery of chambers, now known as the “Greater Vaults”, was excavated under Psamtik I (664–610 BC) of the Twenty-sixth Dynasty and later extended to approximately 350 m in length, 5 m tall and 3 m wide by the Ptolemaic dynasty along with a long, parallel service tunnel. These gallery chambers contained granite and diorite sarcophagi, some weighing up to 70 tons (including lid), though all were found empty. The preceding the generally accepted view.

The 24 tombs of the Great Vault, as well as 40 other giant sarcophagi Mariette discovered buried under sand, represent generations of bulls and the survival of a cult that may have originated as early as 4,000 BCE.

This site is absolutely amazing and I have my doubts concerning the “conventional” wisdom. Why were absolutely no remains of the Apis Bulls found? What technology was used to transport the 70 ton sarcophagi deep underground and along the hallway of the Great Vault?
