what is the greek story of the constellation “cassiopeia”?
Long ago in ethiopia Cassiopeia has been the wife of Cepheus and the mother of Andromeda. Because she thought herself more beautiful than the daughters of Nereus, a god of the sea, she challanged the anger of the god Poseidon. To punish her, her daughter was chained to a rock of the coast as a sacrifice for a sea monster. Andromeda was saved from death by Perseus. (Publius Ovidius Naso: Metamophoses, IV) To learn humility Cassiopeia was banned to the sky hanging half of the time head downward.
