Rozière examines the ancient geographical references to the Red Sea island known as Ophiodes or Topazos and to Ptolemy’s Smaragdus mons, or Mountain of Emeralds, attempting to reconcile the descriptions of classical authors with geographical observations made during the French expedition to Egypt. Drawing particularly on Strabo and Ptolemy, he argues that the supposed Mountain of Emeralds was not situated on the mainland, as commonly believed, but on the island then known as Siberget or Uzzumurud in the Red Sea. He supports this identification from Ptolemy’s coordinates, the island’s distinctive topography, surviving traditions, and physical evidence of ancient mining, including deep shafts and fragments of antique lamps. Rozière further proposes that the island of Topazos and the Smaragdus mons were one and the same locality, despite their differing ancient names, reasoning that there is no evidence for two separate gem-producing islands in the region. He suggests that the Greeks may have exploited both “topaz” and emerald on this island, thereby explaining the apparent contradictions among ancient geographical and mineralogical accounts.
