The female deities had in fact, for the most part, an unsubstantial character: they were ordinarily the mere reflex image of the male, and consequently could not stand alone, but required the support of the stronger sex to give then something of substance and reality.

This was the general rule; but at the same time it was not without certain exceptions.

Ishtar appears almost always as an independent and unattached divinity; while Beltis and Gula are presented to us in colors as strong and a form as distinct as their husbands, Bel and Shamas.

Again, there are minor goddesses, such as Telita, the goddess of the great marshes near Babylon, who stand alone, unaccompanied by any male.

The minor male divinities are also, it would seem, very generally without female counterparts.
Of these minor male divinities the most noticeable are Martu, a son of Anu, who is called "the minister of the deep," and seems to correspond to the Greek Erebus; Sargana, another son of Anu, from whom Sargon is thought by some to have derived his name Idak, god of the Tigris; Supulat, lord of the Euphrates; and Il or Ra, who seems to be the Babylonian chief god transferred to Assyria, and there placed in a humble position.
