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.
Dilmun appears first in Sumerian cuneiform clay tablets dated to the late third millennium BC, found in the temple of goddess Inanna, in the city of Uruk. The adjective Dilmun is used to describe a type of axe and one specific official; in addition there are lists of rations of wool issued to people connected with Dilmun.
Dilmun was mentioned in two letters dated to the reign of Burnaburiash (c. 1370 BC) recovered from Nippur, during the Kassite dynasty of Babylon. These letters were from a provincial official, Ilī-ippašra, in Dilmun to his friend Enlil-kidinni, the governor of Nippur. The names referred to are Akkadian. These letters and other documents, hint at an administrative relationship between Dilmun and Babylon at that time. Following the collapse of the Kassite dynasty, Mesopotamian documents make no mention of Dilmun with the exception of Assyrian inscriptions dated to 1250 BC which proclaimed the Assyrian king to be king of Dilmun and Meluhha, as well as Lower Sea and Upper Sea. Assyrian inscriptions recorded tribute from Dilmun. There are other Assyrian inscriptions during the first millennium BC indicating Assyrian sovereignty over Dilmun. One of the early sites discovered in Bahrain suggests that Sennacherib, king of Assyria (707–681 BC), attacked northeast Arabia and captured the Bahrainian islands. The most recent reference to Dilmun came during the Neo-Babylonian dynasty. Neo-Babylonian administrative records, dated 567 BC, stated that Dilmun was controlled by the king of Babylon. The name of Dilmun fell from use after the collapse of Babylon in 538 BC.
There is both literary and archaeological evidence of trade between Ancient Mesopotamia and the Indus Valley civilization (probably correctly identified with the land called Meluhha in Akkadian). Impressions of clay seals from the Indus Valley city of Harappa were evidently used to seal bundles of merchandise, as clay seal impressions with cord or sack marks on the reverse side testify. A number of these Indus Valley seals have turned up at Ur and other Mesopotamian sites. The "Persian Gulf" types of circular, stamped (rather than rolled) seals known from Dilmun, that appear at Lothal in Gujarat, India, and Failaka, as well as in Mesopotamia, are convincing corroboration of the long-distance sea trade. What the commerce consisted of is less known: timber and precious woods, ivory, lapis lazuli, gold, and luxury goods such as carnelian and glazed stone beads, pearls from the Persian Gulf, shell and bone inlays, were among the goods sent to Mesopotamia in exchange for silver, tin, woolen textiles, olive oil and grains. Copper ingots from Oman and bitumen which occurred naturally in Mesopotamia may have been exchanged for cotton textiles and domestic fowl, major products of the Indus region that are not native to Mesopotamia. Instances of all of these trade goods have been found. The importance of this trade is shown by the fact that the weights and measures used at Dilmun were in fact identical to those used by the Indus, and were not those used in Southern Mesopotamia.
Mesopotamian trade documents, lists of goods, and official inscriptions mentioning Meluhha supplement Harappan seals and archaeological finds. Literary references to Meluhhan trade date from the Akkadian, the Third Dynasty of Ur, and Isin-Larsa Periods (c. 2350–1800 BC), but the trade probably started in the Early Dynastic Period (c. 2600 BC). Some Meluhhan vessels may have sailed directly to Mesopotamian ports, but by the Isin-Larsa Period, Dilmun monopolized the trade. The Bahrain National Museum assesses that its "Golden Age" lasted ca. 2200-1600 BC. Discoveries of ruins under the Persian Gulf maybe of Dilmun.
Dilmun and mythology 
Dilmun, sometimes described as "the place where the sun rises" and "the Land of the Living", is the scene of some versions of the Sumerian creation myth, and the place where the deified Sumerian hero of the flood, Utnapishtim (Ziusudra), was taken by the gods to live forever. Thorkild Jacobsen's translation of the Eridu Genesis calls it "Mount Dilmun" which he locates as a "faraway, half-mythical place".
For Dilmun, the land of my lady's heart, I will create long waterways, rivers and canals, whereby water will flow to quench the thirst of all beings and bring abundance to all that lives.
However, in the early epic "Enmerkar and the Lord of Aratta", the main events, which center on Enmerkar's construction of the ziggurats in Uruk and Eridu, are described as taking place in a world "before Dilmun had yet been settled".
Locating Dilmun 
As of 2008, archaeologists have failed to find a site in existence during the time from 3300 BC (Uruk IV) to 556 BC (Neo-Babylonian Era), when Dilmun (Telmun) appears in texts. Despite the scholarly consensus that ancient Dilmun encompasses three modern locations: (1) the eastern littoral of Arabia from the vicinity of modern Kuwait to Bahrain; (2) the island of Bahrain; (3) the island of Failaka east of Kuwait, few have taken into account the radically different geography of the basin represented by the Persian Gulf before its reflooding as sea levels rose about 6000 BCE; the earliest known site is Qal'at al-Bahrain which is dated no earlier than c. 2200 BC according to Flemming Hojlund. Failaka was settled after 2000 BC following a drop in sea level. No settlements exist in the Arabian littoral 3300-2000 BC according to Hojlund. Thus, despite Dilmun's appearance in ancient texts dating from 3300-2300 BC archaeologists have failed to find a site for Dilmun dating to this period. Hymns regarding the Sumerian god Enki of Eridu in Sumer speak of his assaulting and deflowering Dilmun's maidens as they stand by a river bank, he reaching out of nearby marsh to clasp them to his bosom. Of Bahrain, Failaka, and the eastern littoral of Arabia, none possess marshes and a riverbank. Dilmun, furthermore, is said to lie "in the east where the sun rises," a situation that does not apply to the eastern Arabian littoral, Failaka or Bahrain, all of which lie south of Sumer and Eridu.
Theresa Howard-Carter (1987) realizing that these three locations possess no archaeological evidence of a settlement dating 3300-2300 BC, has proposed that Dilmun of this era might be a still unidentified tell near the Shatt al-Arab between modern-day Qurnah and Basra in modern day Iraq. In favor of Howard-Carter's proposal, she noted that this area does lie to the east of Sumer ("where the sun rises"), and the riverbank where Dilmun's maidens would have been accosted aligns with the Shat al-Arab which is in the midst of marshes. The "mouth of the rivers" where Dilmun was said to lie is for her the union of the Tigris and Euphrates at Qurnah.
Some scholars maintain that the Sumerians may have originated from the mountainous regions of southwestern Iran, since their epic poems refer several times to western part of Iran as their original homeland. Samuel Noah Kramer, a renowned expert in Sumerian history says, "There is some reason to believe that their original home had been in the neighborhood of a city called Aratta, which may have been near the Caspian sea: Sumerian epic poets say something of Aratta, and its people were said to speak the Sumerian language". Martha Lamberg Karlovsky, notes the "The kingdom of Elam and its somewhat better-known neighbor, Sumer, were the two earliest urban states to arise in the Mesopotamian area during the fourth millenium B.C. Proto-Elamite inscriptions and early Sumerian ones are the earliest known Mesopotamian writings, which are the oldest known anywhere".
