Dialogues of the Gods (14.1)

Your monster of the deep, my dear Nereids, the one of you sent against Andromeda, the daughter of Cepheus, didn’t harm the girl, as you’ve been thinking it would, but is now dead itself.

Who killed it, Triton? Did Cepheus set the girl there like a bait, and then attack and kill it, after lying in wait for it with a large force?

No. But I imagine, Iphianassa, you all know what happened to Perseus, Danae’s child, whom his mother’s father threw into the sea in a chest with his mother, and you saved out out of pity.

I know whom you mean. He must be a young man by now, and a very fine handsome fellow.

It was he who killed the monster.

Why, Triton? He shouldn’t have paid us in this coin for saving him.
