But the god of earthquakes reassured the Smith,
"Look, Hephaestus, if Ares scuttles off and away,
squirming out of his debt, I’ll pay the fine myself."

– Homer

The Odyssey, Book 8, lines 397-399. Bard Demodocus is singing a bawdy song in which Ares sleeps with Hephaestus’ wife Aphrodite and they both end up being chained to the bed. In this passage Poseidon plays the mediator, brokering a reconciliation between Hephaestus and Ares.
