The underlying peaty stratum, containing the piles, occupied much of Parazzi's attention, and he goes largely into its minutiæ. One curious fact which he records is that the dyke passed over its middle, leaving a considerable portion of the _terra torbosa_ and palafitte outside the area of the terramara deposits. This undoubtedly suggests the idea that the palafitte existed prior to the terramara settlement. From the character of the relics we shall, however, see that both belonged to the same age and people. On the surface of the terramara beds Roman remains were largely met with, and in one place they came upon a rectangular excavation, measuring 18 square mètres, containing ordinary earth, bricks, tiles, fragments of jars, and other Roman pottery. When this was cleared out there was found at the bottom, at a depth of 7 feet 6 inches, a Roman pavement, and the stratified terramara layers could be distinctly seen in the perpendicular walls. Clearly this cellar was constructed long after the deposition of the terramara beds. Nor is the settlement of Casale Zaffanella a solitary example in the Viadana district. Already Parazzi has prepared a large map of the neighbourhood, which finds a suitable position on the wall of his museum, with no less than 12 terramara stations marked on it. Among these there is one Cogozzo (B. 372b) situated about one-and-a-quarter mile from the town and within 200 yards of the Po, which presents the same features as that at Casale Zaffanella, and also contains traces of a palafitte. Its area is an orientated quadrangle covering about an acre, but it is completely buried in mud, its highest point being 31 inches below the surface. It is surrounded by a ditch and dyke; and, moreover, the inner edge of the dyke was found to be almost perpendicular, showing that originally it must have had some kind of _contrafforte_. Some of the objects from this group of terramara stations, now deposited in the Viadana Museum, are represented in =Fig. 86=, Nos. 1 to 13. GORZANO (MODENA). The old-school views advocated by Dr. Coppi, viz. that the terremare were remains of funeral pyres (_roghi_), so much biassed his mind that for many years he appeared to have paid little attention to the significance of the strata, and consequently the first two volumes of his magnificently illustrated monograph on the terramara settlement at Gorzano (B. 207 and 261) lose much of their value from having the objects of different ages indiscriminately mixed. This defect is so far removed in the third volume that he divides the deposits into upper and lower, corresponding to the historic and prehistoric periods. But, notwithstanding this defect in Dr. Coppi's earlier works, his investigations are of considerable scientific value, as his numerous matter-of-fact observations are strictly to be depended on.
