"This coin depicts the city's foundation myth. A young girl, going to fetch water, was attacked by a snake. She was rescued by two young men but they could not kill the snake because it was a god. The Etenna people descended from the union of the snake and the girl."
These are amazing coins and I was busy with them a long time. But there is not enough information for an entire article. There are coins where you can see that the girl was not raped by the
snake but seems to dance in a complicated choreography (symplegma) with the
snake, especially on the coins with the overthrown
oinochoe.
As example I have attached my own coin.
Best regards
