According to CNN.com a 3,700 year old wall made of 4 to 5 ton boulders has been found in the City of David in Jerusalem. The wall is thought to have been built by the Canaanites as a fortification to connect a fortress on top of a nearby hill to a water source which is still in use today. The Canaanites controlled the eastern shore of the Mediterranean in the 4th millennium B.C. At this time even the Egyptians were just forming their first cities. It would be another thousand years before the Egyptians would construct the great pyramid at Giza.
Did the engineering of great structures originate in Cana’an as fortifications and then evolve into the symbolic form of the pyramid? As with the pyramids, no-one today could use such large material without modern machinery. How’d they do it?
