Her name is again playfully interpreted by the Babylonians--through association with Nin--as 'the lady' _par excellence_. She was the chief goddess of the city of Uruk. Her temple at Uruk is first mentioned by Ur-Gur, of the second dynasty of Ur. It is restored and enlarged by Dungi, the successor of Ur-Bau, and so thoroughly is she identified with her edifice known as E-anna (again a play upon her name), that she becomes known as the Lady of E-anna.[66] She appears to have had a temple also at Ur, and it is to this edifice that later rulers of Larsa--Kudur-Mabuk and Rim-Sin, as well as the kings of the Isin dynasty, Gamil-Ninib, Libit-Ishtar, and Ishme-Dagan--refer in their inscriptions. The members of the Isin dynasty pride themselves upon their control over Uruk, and naturally appear as special devotees to Nana, whose chosen "consort" they declare themselves to be, wielding the sceptre, as it were, in union with her. Already at this period, Nana is brought into connection with the moon-god, being called by Kudur-Mabuk the daughter of Sin. The relationship in this case indicates, primarily, the supremacy exercised by Ur, and also a similarity in the traits of the two deities. In the fully developed cosmology, Nana is the planet Venus, whose various aspects, as morning and evening star, suggested an analogy with the phases of the moon. Venus, like the moon, served as a guide to man, while her inferiority in size and importance to the former, would naturally come to be expressed under the picture of father and daughter. In a certain sense, all the planets appearing at the same time and in the same region with the moon were the children of the latter. Sin, therefore, is appropriately called the father of gods, just as Anu, the personification of the heaven itself, is the supreme father of Sin and Shamash, and of all the heavenly bodies. The metaphorical application of 'father' as 'source,' throughout Oriental parlance, must be kept in mind in interpreting the relationship between the gods. Still another name of the goddess is Anunit, which appears to have been peculiar to the North Babylonian city Agade, and emphasizes her descent from "Anu," the god of heaven. Her temple at Agade, known as E-ul-mash, is the object of Sargon's devotion, which makes her, with Bel and Shamash, the oldest triad of gods mentioned in the Babylonian inscriptions. But the name which finally displaces all others, is Ishtar. Where the name originated has not yet been ascertained, as little as its etymology,[67] but it seems to belong to Northern Babylonia rather than to the south.
