The Chained Lady

The constellation of Andromeda

In Greek mythology, Andromeda was the daughter of King Cepheus and Queen Cassiopeia of Æthiopia (what we call the Upper Nile region). Cassiopeia boasted that she and her daughter was more beautiful than the Nereids, the sea nymphs who often accompanied Poseiden, god of the seas. As punishment, Poseiden sent a sea monster, Cetus, to ravage the coast of Æthopia. In desperation, Cepheus consulted an oracle who informed him that to appease Poseiden, Cepheus must sacrifice his daughter Andromeda to the sea monster. Thus, Andromeda was stripped naked and chained to the rocks on the coast of the sea. Fortunately for her, Perseus was passing by, having just slain the Gorgon, Medusa. He killed the sea monster and set Andromeda free, claiming her as his bride.

The obsolete constellation Honores Friderici is comprised of stars now assigned to Andromeda.
