The Cepheus constellation is located in the northern hemisphere and is one of the 88 modern constellations. But how did it come to be named after a king from Greek mythology? Let’s take a closer look at the history and mythology behind the Cepheus constellation.

History of the Cepheus Constellation

The Cepheus constellation has been known since ancient times, and it was included in Ptolemy’s 2nd century AD list of 48 constellations. The constellation was originally named after a king in Greek mythology named Cepheus, who was said to have ruled Ethiopia. However, it was later also associated with a king from Phoenicia, also named Cepheus.

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.
