The artisans under the patronage of #Hephaistos and #Athena built their workshops nearby. Homer writes in the #Odyssey:
"As when a man adds gold to a silver vessel, a craftsman taught by Hephaistos and Athene to master his art through all its range, so that everything that he makes is beautiful."
Hephaistos and Athena seem to share most of the crafts. Only metalurgy and smithing seems to be Hephaistos' domain alone, just as weaving is the sole sphere of Athena.
