Anahita?

This dish with "the dancer" (as some people like to call it) is in the Cleveland museum of art: Official description: Dish: The Goddess Anahita, Iran, Sasanian, 5th-6th Century AD...

Anahita was the Zoroastrian goddess of water and fertility, whose epithet was "Arədvī" thought to mean "moist"...

Which is why she is depicted like this:

As a goddess of water, she is depicted holding a bow, with wavy water line going through it and with vajra (symbol for lightning???) in the middle of it, most likely a symbolic depiction of a rain-bow...

As a fertility goddess she is depicted on this plate with plants (tree of life???) growing out of this bow, rainbow, rain, water...

Now remember that climate in Western Iran and Iraq, the centre of the Sasanian empire, consists of two seasons: dry season (May-Oct) and wet season (Nov-Apr). Here is average precipitation for Tehran and Bagdad...

Rainbows only appears in the sky in Sassanian lands during the rain season. And it is this rain which falls during the rain season which makes the otherwise dry desert lands of Mesopotamia fertile...

Now have a look at this:

Iran, Sasanian period, 6th-7th century AD silver and gilt plate. 

This plate depicts the same tree of life except it grows from between two prancing ibex goats and not from the body of Anahita, the moist one, the goddess of water...

Why? 

The rain season, the fertile season, the season ruled by the goddess of water and fertility "the moist one", starts when Ibexes goats start prancing about, at the beginning of their mating season, end of October - beginning of November...

We find this link between Ibex (Bezoar) goats and rain in all the lands between Eastern Mediterranean and Pakistan, where the rain season arrives at the time when Ibex goats are mating....I talked about this in several of my blog posts...

So was there originally a link between Anahita and Ibex goats?
