In Greek mythology, King Erichthonius (; ) was a legendary early ruler of ancient Athens. According to some myths, he was autochthonous (born of the soil, or Earth) and adopted or raised by the goddess Athena. Early Greek texts do not distinguish between him and Erechtheus, his grandson, but by the fourth century BC, during Classical times, they are distinct figures. Etymology Erichthonius of uncertain etymology is possibly related to a pre-Greek form *Erekteu-. The connection of with ἐρέχθω, "shake" is a late folk-etymology; other folk-etymologies include , erion, "wool" or eris, "strife"+ chthôn or chthonos, "earth". Mythology Birth According to the Bibliotheca, Athena visited the smith-god Hephaestus to request some weapons, but Hephaestus was so overcome by desire that he tried to seduce her in his workshop. Determined to maintain her virginity, Athena fled, pursued by Hephaestus. He caught Athena and tried to rape her, but she fought him off. During the struggle, his semen fell on her thigh, and Athena, in disgust, wiped it away with a scrap of wool (, erion) and flung it to the earth (, chthôn). As she fled, Erichthonius was born from the semen that fell to the earth. Athena, wishing to raise the child in secret, placed him in a small box and then made sure no one would ever find out by giving him away. Athena gave the box to the three daughters (Herse, Aglaurus and Pandrosus) of Cecrops, the king of Athens, and warned them never to look inside. Pandrosus obeyed, but Herse and Aglaurus were overcome with curiosity and opened the box, which contained the infant and future-king, Erichthonius ("troubles born from the earth," following another etymology). (Sources are unclear regarding how many sisters participated.) The sisters were terrified by what they saw in the box: Either a snake coiled around an infant, or an infant that was half-human and half-serpent. They went insane and threw themselves off the Acropolis. Other accounts state that they were killed by the snake. An alternative version of the story is that Athena left the box with the daughters of Cecrops while she went to fetch a limestone mountain from the Pallene peninsula to use in the Acropolis. While she was away, Aglaurus and Herse opened the box. A crow saw them open the box, and flew away to tell Athena, who fell into a rage and dropped the mountain she was carrying
