Named for a mosaic that has since been moved to a Naples museum, this is an excellent example of a middle-class Roman empire house. Not large, but richly decorated to showcase the owner's wealth.
The house is connected to some shops, indicating that it belonged to a merchant. The entrance has a mosaic of a large chained dog with the inscription Cave Canem – Beware of the dog.
