In April and May of 2006, we concentrated on documenting the stratigraphy inside triclinium 35 and adjacent areas to the east and west, which included two soundings (SS.45 and 46) in peristyle 31 directly in front of triclinium 35, and one each in shop 4 and the back rooms (5a and 5b) of thermopolium 5 (SS.43 and 44). Further soundings were made in triclinium 13 (S.47), on the north side or peristyle 31 (S.48), in courtyard 26 in the NW corner of the house (S.49), and in portico 21 by the exterior corner of oecus 22 (S.50). In contrast to the numerous soundings made in the north section of insula 2, we found no traces of habitation before the second century B.C. except for a few materials, mostly from the earlier excavations of 1970, which are clearly residual.

An examination of the sterile levels, composed mainly of lava leucita and cenerite, indicates that there was an extensive clearing and leveling operation that cut into the prehistoric layer in order to build the original house, dating to the Late Samnite Period.

Therefore, the hypothetical plan of the house for the mid-second century B.C., proposed by Anne Laidlaw in 1970 and reprinted successively in numerous publications, needs substantial adjustments. This plan will be updated as soon as possible, based on the study of the structure and materials presently under way at the University of Perugia and the American Academy in Rome.
