The Constellation Cassiopeia

Cassiopeia, metghology of the Queen Cassiopeia was always bragging that she and her daughter Andromeda were more beautiful than the sea nymphs. This angered Poseidon, the god of the sea. Poseidon sent Cetus the sea monster to destroy her kingdom. In order to save her kingdom, she chained her daughter to a rock by the sea as a sacrifice to the sea monster. Perseus saved Andromeda from the sea monster. Posiedon still wanted to punish Cassiopeia so he put her into the night sky where she would hang upside down on her chair for half of her eternal life. And that's the story of the queen Cassiopeia. You can still see her haning upside down if you can see the W shape or the M shape in the night sky near the little dipper!   star map of cassiopeia
