Aix

Aix (or Aex) was the nymph or possibly goat wife of the god Pan. She was seduced by Zeus and bore him son named Aigipan.

Other
Aix may be the same as Aix Amaltheia, the goatish nurse of Zeus in the Diktaion cave. She was also probably also identified with the primordial Gorgon Aix, whose skin was crafted into the aigis shield.
