Pyramids not built by slaves

Zahi Hawass (C), the secretary general of Egypt's Supreme Council of Antiquities (ESCA) speaks to media in front of tombs belonging to the workers who built the great pyramids in Giza, on the outskirts of Cairo, Jan. 11, 2010.  New tombs found in Giza support the view that the Great Pyramids were built by free workers and not slaves, as widely believed, said Zahi Hawass. The newly discovered tombs date to Egypt's 4th Dynasty (2575 B.C. to 2467 B.C.) when the great pyramids were built, according to Zahi Hawass. [Xinhua]
