Myth

Andromeda is the Greek daughter of Queen Cassiopeia and King Cephus of Ethiopia. Andromeda was very beautiful making Hera, wife of Zeus, very jealous. Poor Andromeda’s fate was sealed when she was sacrificed to the sea-monstor, Tiamat (shown in thesky as Cetus) but like all good maidens she was saved by a handsome prince, Perseus on the back of Pegasus, the winged horse.
