Cetus
Origin
Cetus is named after the monster Cetus that in Greek myth was sent by Poseidon to terrorize the coasts of Ethiopia after feeling insulted by the queen Cassiopeia who declared that she was more beautiful than his water nymphs. The king, on the instruction of an oracle, intended to sacrifice the princess Andromeda in order to stop the beast, but the hero Perseus slew it before it could get to her.
