Stratigraphic excavation in the atrium d1, the peristyle and the cubiculum S2 of the House of M. Epidius Sabinus IX.1.29, undertaken during the years 2004 and 2006, aimed to investigated the building history of the house and the earliest urban occupation of the insula. The results, which are still being processed, have provided a chronological grid beginning with the construction of a first house of limited size and only a few rooms, dating to the end of the 4th-first half of the 3rd century B.C. This structure was preceded by a cult area whose structures came to light in the area of the future peristyle. The many pottery finds, in particular bucchero and Corinthian ware, provided evidence for the use of the supposed sanctuary from the late 6th century to the 2nd century B.C., the period in which rites to obliterate what remained of the religious structures appear to be evidenced. These were undertaken in order to make way for the great Hellenistic monumentalization of the house with the construction of the peristyle. (Alessandro Gallo)
