Enmerkar and the Lord of Aratta is a legendary Sumerian account, of preserved, early post-Sumerian copies, composed in the Neo-Sumerian period (ca. 21st century BC). It is one of a series of accounts describing the conflicts between Enmerkar, king of Unug-Kulaba (Uruk), and the unnamed king of Aratta (probably somewhere in modern Iran or Armenia).
Because it gives a Sumerian account of the "confusion of tongues", and also involves Enmerkar constructing temples at Eridu and Uruk, it has, since the time of Samuel Kramer, been compared with the Tower of Babel narrative in the Book of Genesis.
Near the beginning of the account, the following background is provided: "In those days of yore, when the destinies were determined, the great princes allowed Unug Kulaba's E-ana to lift its head high. Plenty, and carp floods and the rain which brings forth dappled barley were then increased in Unug Kulaba. Before the land of Dilmun yet existed, the E-ana of Unug Kulaba was well founded."
E-ana was a temple in Uruk built in honour of the goddess Inanna, the "lady of all the lands"–(E-ana is 'house of An', or 'Temple of An'). Similarly, the lord of Aratta has himself crowned in Inanna's name, but she does not find this as pleasing as her brick temple in Uruk.
Enmerkar, thus "chosen by Inanna in her holy heart from the bright mountain", then asks Inanna to let him subject Aratta and make the people of Aratta deliver a tribute of precious metals and gemstones, for constructing the lofty Abzu temple of Enki at Eridu, as well as for embellishing her own E-ana sanctuary at Uruk. Inanna accordingly advises Enmerkar to dispatch a herald across the mountains of Susin and Anshan to the lord of Aratta, to demand his submission and his tribute.
