Danaus
Danaus was
the son of king Belus and Queen Anchinoe of Egypt and his brother was Aegyptus.
The brothers were on bad terms, and to make peace Aegyptus wanted his 50 sons
to marry Danaus's 50 daughters, the Danaids. The girls refused, and together
with their father they fled to Argus, where Danaus became king. The 50 sons
followed them there, and Danaus decided to let the marriages happen. He entrusted
each daughter with a knife, and on their wedding night all but one murdered
Aegyptus sons.
The disobedient, eldest daughter Hypermnestra was put in prison by her father,
but freed later on. Artemis killed the Danaids for their crime and they were
sent to the underworld, punished to forever try to fill jars with holes in
them.

fiancees:
