Cepheus in Greek Mythology

In Greek mythology, Cepheus was the King of Aethiopia, a kingdom located in Africa. He was the husband of Cassiopeia and the father of Andromeda. Cepheus was known for his intelligence and wisdom, and he was greatly respected by his people.

According to the myth, Cassiopeia boasted that her daughter Andromeda was more beautiful than the sea nymphs, the Nereids. This angered the god of the sea, Poseidon, who then sent a sea monster to attack Ethiopia. In response to this threat, Cepheus consulted an oracle, who advised him to sacrifice Andromeda to the monster. Andromeda was then chained to a rock and left to be devoured by the sea monster. However, the hero Perseus, who was returning from his battle with Medusa, saved Andromeda by slaying the monster. As a reward for his bravery, Cepheus allowed Perseus to marry Andromeda.
