Sisyphus was both a clever ruler who made his city prosperous, and a devious tyrant who seduced his niece and killed visitors to show off his power. While his violation of the sacred hospitality tradition greatly angered the gods, it was Sisyphus’ reckless confidence that proved to be his downfall -- resulting in Zeus condemning him for all eternity. Alex Gendler shares the myth of Sisyphus. Lesson by Alex Gendler, directed by Adriatic Animation.
