Metion
In Greek mythology, Metion (; , gen. Μητίονος) was a son of King Erechtheus of Athens or of Eupalamus, son of King Erechtheus. His sons later drove King Pandion II out of Athens into exile. Among these sons were Eupalamus, Sicyon, and Daedalus, though they are sometime credited with other parentages. These usurping sons were in turn overthrown by the sons of Pandion.
