Okypete was one of the fifty Daniads who married the fifty sons of King Aigyptos. Okypete married Lampus. The night of the mass marriage Okypete and forty-eight of her dorty-nine sisters and half sisters murdered their respective husbands.
When Oxypete and the other Danaids who had murdered their husbands they were sent to Tartarus and were forced to carry water from the river Styx in a bowls (or jars according to some) with holes over to a tub which leaks at multiple parts. Oxypete and the others were told only when they filled the tub could they wash away their sins. The Danaids continue this essentially impossible task to this very day.
