Cassiopeia Queen of Ethiopia or Andromeda's Mother some stars: Shedir - "breast" Caph - "palm" (reaching from the Pleiades) Ruchbah - "knee" Cassiopeia boasted that she and her daughter were more beautiful than the Nereids (or sea nymphs), which were the daughters of Poseidon (or Neptune), the god of the sea. The Romans described her chained to her throne in the heavens as punishment for her boastfulness. As the sky appears to rotate, she can sometimes be seen suffering as she hangs upside down.
