Origins of the myth 

The section suggesting that the myth originated via the constellations should, I think, be deleted.  Besides being an over-simplification of the complexities of mythology, it is wrong.  Astrology, though which mythological significance might be applied to the stars, did not arrive in Greece until the 4th c. BC, hundreds of years after the principle formation of the myth.  Therefore, the constellations could not have been the foundation of the myth, but are instead an aftereffect of it, a novel way of using the myth at a later time.MS
