The Brygi, who dwelt at this time in the vicinity of Ennea Hodoi, had given Mardonius a severe defeat on a former occasion; and the Persians were apt to treasure up such wrongs, and visit them, when occasion offered, with extreme severity.
When the Persians had once yielded to the syncretic spirit so far as to unite the Magian tenets and practices with their primitive belief, they were naturally led on to adopt into their system such portions of the other religions, with which they were brought into close contact, as possessed an attraction for them.

Before the date of Herodotus they had borrowed from the Babylonians the worship of a Nature-Goddess, whom the Greeks identified at one time with Aphrodite, at another with Artemis, at another (probably) with Here, and had thus made a compromise with one of the grossest of the idolatries which, theoretically, they despised and detested.

The Babylonian Venus, called in the original dialect of her native country Nana, was taken into the Pantheon of the Persians, under the name of Nansea, Anaea, Anaitis, or Tanata, and became in a little while one of the principal objects of Persian worship.

At first idolatry, in the literal sense, was avoided; but Artaxerxes Mnemon, the conqueror of Cunaxa, an ardent devotee of the goddess, not content with the mutilated worship which he found established, resolved to show his zeal by introducing into all the chief cities of the Empire the image of his patroness.

At Susa, at Persepolis, at Babylon, at Ecbatana, at Damascus, at Sardis, at Bactra, images of Anaitis were set up by his authority for the adoration of worshippers.
