Athene was born in Libya, beside a lake where she was found and nurtured by three nymphs who dressed in goat-skins. As a girl she killed her playmate Pallas by accident and as a token of grief took her name before her own.
There were more mythological personages named Pallas - a Titan, the 'father of the moon', the father of fifty Pallntids and the father of Athene herself - but these are all male, whilst Pallas means maiden.
