A careful and punctual analysis is carried out of all the almost unprecedented aspects characterizing this house, starting from the composition of its floor plan and building structures, to continue with the architectural and decorative scores of the preparation of each room, such as the wall plaster. paintings and, above all, the beautiful mosaic floors, of which you can admire overall and detailed photos. Added to this is the complete study of the archaeological materials found at the time of the excavation inside the structure and finally cataloged here. The results achieved include a proposal on the scanning of the building phases of the house and on the intended use of the rooms, aiming to significantly expand the panorama of knowledge on domestic construction in Agrigento of the Greek-Roman age and in Sicily in general.
