Kallidike was one of the fifty daughters of King Danaus who married the fifty sons of King Aigyptos. Kallidike was wed to Pandion. On her wedding night, Kallidike like all her sisters (spare Hypermnestra) murdered her husband.
When Kallidike 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. Kallidike 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.

"...Pandion got Callidice; Arbelus got Oime; Hyperbius got Celaeno; Hippocorystes got Hyperippe; the mother of these men was Hephaestine, and the mother of these damsels was Crino."
