In Greek mythology, a violent man who lived near Corinth, where he practiced his unusual pastime: he would threaten and cajole wayfarers into washing their feet, and while they were doing so, he would shove them over the edge of the cliffs into the sea, where they became prey for a gigantic sea turtle.
Skiron's wicked actions came to a violent end, when Theseus gave him the same treatment he had meted out to others. With Skiron's death, the roads became much safer, and Skiron was only remembered in the name given to the cliffs where he had killed so many: the Skironian Cliffs.
Yes, I know - the story of Skiron is a truly curious myth, which apparently loses something in the translation. It must have seemed reasonable to the Greeks, though.
