Danaides
Δαναΐδες
Fifty sisters who killed their husbands on their wedding night.
On their father Danaus's orders, they married their fifty cousins — and killed the grooms that very night.
Only one, Hypermnestra, let her husband live.
In the underworld they are condemned to pour water into a leaking jar — no matter how much they pour, it never fills.
