The main temple to Enki was called E-abzu, meaning “abzu temple” (also E-en-gur-a, meaning “house of the subterranean waters”), a ziggurat temple surrounded by Euphratean marshlands near the ancient Persian Gulf coastline at Eridu.When Ur was founded, the Persian Gulf’s water level was two-and-a-half metres higher than today. Ur is thought, therefore, to have had marshy surroundings; irrigation would have been unnecessary, and the city’s evident canals likely were used for transportation.- Persian Gulf (Wikipedia)
The Persian Gulf (Persian: خلیج فارس, romanized: xalij-e fârs, lit. ‘Gulf of Fars’, pronounced [xæliːdʒe fɒːɾs]), sometimes called the Arabian Gulf (Arabic: اَلْخَلِيْجُ ٱلْعَرَبِيُّ, romanized: Al-Khalīj al-ˁArabī), is a mediterranean sea in West Asia. The body of water is an extension of the Indian Ocean located between Iran and the Arabian Peninsula. It is connected to the Gulf of Oman in the east by the Strait of Hormuz. The Arvand or Shatt al-Arab river delta forms the northwest shoreline.
