Cetus
It is a large fish or whale-like sea monster
from Greek mythology.
Its the sea monsters that both Perseus and
Heracles each killed during one of their adventures.
In Perseus's story, the Cetus was a sea monster
summoned by Poseidon to destroy the shores
of Aethiopia because of rage.
Rather than laughing at the absurdity of Cassiopeia's
statement that her daughter Andromeda was
more beautiful than the Nereids.
The Nereids are sea nymphs they are beautiful,
kind creatures and their most prominent job
was like a personal assistant or Poseidon's
maids.
Not to mention his wife is also a Nereid.
Anyways with the creature slowly making its
way to the shore, Cassiopeia in panic asked
an oracle on what to do.
The oracle said that Andromeda, who was also
a victim here, had to be sacrificed to Cetus
to stop the destruction of their kingdom.
Because of that, Andromeda got chained naked
to a rock on the shore as sacrifice, where
Perseus saw her.
He must have thought she was worth the save
and slew the monster then asked her to marry
him.
A man of action.
While the story with Heracles is almost similar,
there's Poseidon being mad and summoned a
sea monster, a princess was to be sacrificed
tied to a rock and Heracles saved the princess
because he can.
Though, he didn't marry her in the end, so,
almost a similar story.
