To punish the queen's arrogance, Poseidon sent a sea monster, Cetus, to ravage the kingdom.
Andromeda was chained to a rock by the sea as an offering to Cetus.
Perseus used Medusa’s severed head, whose gaze turned creatures to stone, to defeat Cetus.
She became the constellation Andromeda, placed in the sky alongside Perseus, Cassiopeia, Cepheus, and Cetus.
The constellation is part of the narrative of Andromeda, Perseus, and the sea monster Cetus.
"The head of Andromeda is setting and against her is brought by the misty South the mighty terror, Cetus."
Andromeda, a mortal princess, is tied to a rock as a sacrifice to the sea monster Cetus.
More familiar faces were seen here; Cetus and Ulysses were at feud ; they had first quarrelled over an animal, which both claimed to have killed, then over some land which both wanted, and finally over a woman whom both desired.
