Cassiopeia was the wife of Cepheus (Cepheus was a king of Ethiopia). Cassiopeia proclaimed that she was so beautiful that her appearance put the Nereids to shame.

The Nereids shared their displeasure with Poseidon, the Greek god of the sea. Poseidon decided that this expression of mortal vanity was too much and punished her.. However, the story of Cassiopeia does not quite end there.

Legend has it that the vain Cassiopeia did ultimately achieve star status. She was transformed into the constellation that bears her name, and this group of stars reminds us forever of Cassiopeia's somewhat dubious contribution to Greek myth.
