Though married to Hephaestus, Aphrodite had an affair with Ares, the god of war. Eventually, Hephaestus discovered Aphrodite’s affair through Helios, the all-seeing Sun, and planned a trap during one of their trysts. While Aphrodite and Ares lay together in bed, Hephaestus ensnared them in an unbreakable chain-link net so small as to be invisible and dragged them to Mount Olympus to shame them in front of the other gods for retribution.  

The gods laughed at the sight of these naked lovers, and Poseidon persuaded Hephaestus to free them in return for a guarantee that Ares would pay the adulterer’s fine or that he would pay it himself. Hephaestus states in The Odyssey that he would return Aphrodite to her father and demand back his bride price.
