Located in the southern part of the city this house takes its name from the large mosaic depicting Orpheus playing his harp to an audience of trees, animals and birds. The mosaic is situated in the triclinium, the dining room, where the diners would have reclined on couches set against the walls and admired the central mosaic. Other mosaics can be seen in the atrium, which has a depiction of Amphitrite in a chariot pulled by a seahorse and accompanied by other sea creatures, and in the bathing rooms. One room off the main courtyard has a mosaic of a dolphin, considered by the Romans to be a lucky animal.
