Cassiopeia is known as the Celestial W when below the pole and the Celestia M when above it.
Cassiopeia is bound to her chair and forever circles the pole with her head downward. A fitting punishment by the Nereids (Sea Nymphys) for her boast of being more beautiful than all the Nereids.
Cassiopeia was the wife of Cepheus and mother of Andromeda.
The mother of Andromeda and mother in law of Perseus. She was supposed to be very vain and was made to hang upside down over the North Pole because of it.
