Mythology Behind the Cepheus Constellation

In Greek mythology, Cepheus was the husband of Cassiopeia and the father of Andromeda. According to legend, Cassiopeia boasted that she was more beautiful than the sea nymphs, which angered Poseidon, the god of the sea. To punish Cassiopeia, Poseidon sent a sea monster to attack Ethiopia. In order to appease the monster and save his people, Cepheus was forced to sacrifice his daughter, Andromeda, by chaining her to a rock by the sea. However, she was saved by the hero Perseus, who turned the monster to stone with the head of Medusa.

In another version of the myth, Cepheus was punished by Zeus for his hubris and was placed in the sky as a constellation.
