John Anthony West

Author, lecturer and guide, John Anthony West delivered a seismic shock to archaeology in the early 1990's when he and Boston University geologist Robert Schoch revealed that the Great Sphinx of Giza, Egypt, showed evidence of rainfall erosion. Such erosion could only mean that the Sphinx was carved during or before the rains that marked the transition of northern Africa from the last Ice Age to the present interglacial epoch, a transition that occurred in the millennia from 10,000 to 5000 BC.
