The pottery from the sites excavated in 1957 and 1958 came, in the main, from two strata: the earlier occupation material on, and thrown over, the scarp on the western edge of the knoll on the north side of the north-west gate and the tips of the great earth and stone rampart of the fifth-century Etruscan defences. The former consists of two groups which are drawn and described as such below, Groups Al and A2. The latter is made up of a variety of sherds dating from the seventh, sixth and fifth centuries B.C., probably scraped up from the surface earth nearby in the making-up of the rampart, so that only representative sherds have been published as types of some particular ware, as dating evidence, or as comparative material. The cuniculi found in both years' excavations, apparently broken into and deliberately filled prior to the building of the rampart and the rampart wall, contained, as well as a number of earlier sherds, a quantity of three specialised pottery types, and these have been published fully, Groups B, C and D.
There are, in addition several small stratified groups. First the early material: Group A3 on the eastern side of the knoll, and, on the western side, the filling of the post-holes and gullies of the earliest timber structures. Both these are considered with Groups Al and A2.
