The Domus is one of the first preserved relics as a result of the modern archaeological excavations.
The preserved part may have been arranged around a large columned courtyard or peristyle. Chronologically dated between the end of the first century A.C and the first half of the fourth, it must have belonged to an important family in the city, which would explain why its various renovations and expansions reached even to occupy a public space on a sewer. The rooms were paved in different materials, according to their importance, using signinum opus, soil mortar mixed with brick fragments for service areas and bedrooms; opus spicatum or pavement brick on edge provided in the form of fish bones, for dining rooms and offices, and a unique mosaic for the Uecus or the reception or guests' hall.
The rooms were decorated with murals with plant motifs. Parallel to the edge of the street, the house had a small thermal complex, heated up by hipocastum, of private usage.
The reception hall or Uecus was devised in the change of the second century to the third an it has the so-called mosaic of the bear and the birds. Made with small limestone tiles, the mosaic was devoted to Orpheus. While outdoor scenes are an allegory of the autumn through branches and bunches of grapes crushed by birds, the motifs inside ordered eight medallions of animals typical of the myth of Orpheus, who would graze them with the strumming of his lyre, a gift from Apollo,since the lyre represents the soul and the animals, the body.
