Dilmun

Dilmun or Telmun (Arabic: دلمون) is a land mentioned by Mesopotamian civilizations as a trade partner, a source of the metal copper, and an entrepôt of the Mesopotamia-to-Indus Valley Civilization trade route. Although the exact location of Dilmun is unclear, it might be associated with the islands of Bahrain, the Eastern Province of Saudi Arabia, Qatar, Oman and nearby Iranian coast in the Persian Gulf. It is also noted that Gilgamesh had to pass through Mount Mashu to reach Dilmun in the Epic of Gilgamesh, which is usually identified with the whole of the parallel Lebanon and Anti-Lebanon ranges, with the narrow gap between these mountains constituting the tunnel.
