COVER

Twin monolithic quartzite statues ofthe Egyptian pharaoh Amenhotep III(18th dynasty, circa 1400 B.C.) areidentified in classical times with theGreek hero Memnon. Research in1971 and 1972, supported by the Na-tional Geographic Society, showedthat each statue weighs 720 metrictons and stands 14.3 meters aboveits pedestal block. The material wassecured at Gebel el Ahmar, 420 milesdownstream on the Nile. See page1219. [Fred Stross, University of Cali-fornia, Berkeley]
