Supporting image forth e Cupid mosaic. This is the top of the mosaic in the house of Amphitrite. The woman is believed robe either Amphitrite who is the wife of Neptune or Venus. She has two men with serpent tails and maybe lobster crowns on either side of her. You can see some pieces are missing due to the fact this mosaic was on the floor and was walked on, which might be why they chose to use tile instead on just painting the floors.
