Plato writes the two of them also share a workshop where they practise their favourite arts:
"He [Prometheus] entered by stealth into the common workshop of Athene and Hephaistos, in which they used to practise their favourite arts, and carried off Hephaistos' art of working by fire, and also the art of Athene, and gave them to man."
Plato, Protagoras 320c - 222a
