New optical mineralogy and pXRF studies of ceramics from First Dynasty royal tombs at Abydos and from Tel Bet Yerah, in the Jordan Valley, reveal a very close correlation between vessels from Egypt and both fired and unfired wares from a potter's establishment at Tel Bet Yerah, marking the first time that vessels found in Egypt can be attributed a site-specific origin in the Levant. Other vessels, most of them previously identified as ‘metallic ware’, included some that likely originated in the northern Jordan Valley and two vessels from a the Lebanese Biqâ valley or Lebanese coast. The vessels found in Egypt most likely span the entire First Dynasty, beginning with Djer, whereas the equivalent material from Tel Bet Yerah falls in the EB II/ESL 4 period, radiometrically dated at Bet Yerah to ca. 3100–2900 BCE. No evidence was found for a more southerly origin of imported Levantine wares in the First Dynasty.
