Vulcan, in a clumsy attempt to ravish Minerva, accidentally let his semen spill over the ground and thus fertilised Mother Earth who gave birth to Erichthonius. Minerva shut the infant in a basket and entrusted it to the three daughters of Cecrops, King of Attica, but forbade them to look inside. Overcome by curiosity one looked inside and discovered that the infant had a serpent's tale for legs. The three daughters threw themselves from the Acropolis in fear. Erichthonius was then raised by Minerva and later became King of Athens.
