Ištar of Nineveh at first glance presents a dilemma for the researcher. While she was a most important goddess, patron of a major town in north Mesopotamia, very little is known about her. As to her importance, in Hurrian religion Teššub and Ša'uška of Nineveh were heads of the pantheon. Here she is given her Hurrian name, Ša'uška. Thus the Mitanni king Tušratta in the Amarna letter no. 23, to Amenophis III, writes that Ša'uška of Nineveh, lady of all the lands (dMÙŠ šauruni-i-na nin kur-kur gáb-bi-i-ši-na-ma), wanted to travel to Egypt and to return. She is further called “lady of heaven” (nin ša-me-e) and “our lady” (nin-ne). Amarna letter no. 24, from the same Mitanni king to the same Pharaoh, refers to Ša'uška of Nineveh as “my goddess” (uruni-i-nu-a-a-we dša-uš-ka-a-wa de-en-ni-iw-wu-ú-a: VS XII 200 iii 98). One might conclude that “lady of heaven” alludes to her as Venus in the sky, but it might also mean the abode of the good gods without any astral allusion. It has been alleged that her wish to travel to Egypt was in the capacity of a goddess of healing, to cure the Pharaoh of his malady, but this is mere speculation. The letter gives no hint of this.

This brief international affair illustrates the problems excellently. There is a mass of cuneiform material bearing on the Sumerian Inanna and her Babylono-Assyrian counterpart Ištar, especially hymns and prayers. From them one can extract her major attributes — sexuality and war — and her astral presence in the planet Venus. The occurrence of related gods in other ancient Near Eastern regions — Aštart and Anat in Syria, Aṯtar in Arabia — suggests that the origins of the cult go back perhaps to neolithic time or even earlier, and the certain relationship with the Greek Aphrodite and Roman Venus attests to the power of this cult, however one explains the connection. However, in each Mesopotamian well-established centre of this cult one can assume that local customs and traditions will have added something to the basic “theology” we extract from our general knowledge of the goddess. For Ištar of Nineveh the episode of Tušratta may or may not allude to her star Venus, but otherwise it is totally uninformative about her “theology”. And that is typical for most of the other dated and precisely located evidence.
