" Jaffa…is situated on a hill, and in front of it is a rock on which they point out the marks made by the chains with which Andromeda was fettered; here there is a cult of the legendary goddess Ceto (the Sea-Monster)." Pliny the Elder, Natural History 5. 69
We all know the princess and the dragon motif. (Aarne-Thompson folktale type 300 – Dragon Slayer) The knight errant runs across a damsel in distress of noble birth. He saves her from the local evil monster or ogre and is rewarded with her hand in marriage. Of course, in Greek Mythology it is a little more complicated than that.
Bellephron - Homer tells in Iliad 6. About “Bellerophontes the blameless. To Bellerophontes the gods granted beauty and desirable manhood” As an honored guest “…the lord of wide Lykia King Iobates tendered him full-hearted honor. And “he sent him away with orders to kill the Chimaera” …The chimera was a fire-breathing three headed and daughter of Typhon and Echidna. She was the pet of King Amisodarus, of neighboring Caria, who often used her to abuse his enemies. With a little help from the gods Bellephron slew the beast and accomplished several other heroic quest. “.. Then when the king knew him for the powerful stock of the god, he detained him there, and offered him the hand of his daughter,” and gave him half the kingdom.
