The industrial remains from the upper stratum were as follows:—The central part of a Byzantine crucifix, one lamp, two fibulæ, three rings of bronze, 12 spindle-whorls of terra-cotta (of which four were glazed), one spindle-whorl of amber, one spindle-whorl of glass, two spindle-whorls of talc; of iron there were 20 darts, two lance-heads, eight knives, seven keys, one lock, eight buckles, one horseshoe, one bullock-shoe, and 11 undetermined fragments; five fragments of glass vessels; one sword-handle of wood with bronze mountings; four bronze fragments; 25 pieces of pottery (three with potters mark); a small basin of brick; 52 coins (of which 46 were together); and some slag, etc.
The objects in the upper stratum were mostly associated with the Oratorio di S. Alberto, built about the early part of the seventeenth century, and other mediæval buildings now entirely demolished. It was found to have been built over a still older church, which dated from the third century. A few of the coins were Roman of about the same date, but the largest number dated from the end of the twelfth or commencement of the thirteenth century, and a few were of still later date. There was also a Christian cemetery found containing a number of skeletons.
In 1879 Coppi published (B. 340) an account of further discoveries, and among other objects he describes several stone moulds (10 for pins, five for lance-heads, and seven for daggers), a stone weapon of nephrite, two flint knives, a weight of white marble, etc. Of bronze there are 12 pins, three needles, 20 dagger-blades, five chisels, nine awls, and a small wheel ornamented with graffiti, besides a quantity of other objects of horn, bone, pottery, etc.
In 1885 the workmen came upon a grave embedded in the virgin soil underneath the terramara beds, and supposed to be anterior to their formation. It was constructed of small unhewn stones, and the space enclosed measured 5 feet 10½ inches long, 1 foot broad, and 1 foot deep. This grave contained a human skeleton which lay on the right side with the head towards the east, and along with it were found a spatula of staghorn, fragments of fossil shells, and some bits of carbonised vegetable matter. (Crespellani, "Scavi del Modenese," 1886, p. 11.)
A few of the bronze objects from Gorzano are illustrated on [Fig. 85], Nos. 9, 12 to 14, and 19 to 23.
GENERAL REMARKS ON THE TERRAMARA SETTLEMENTS.
In the above sketch of the progress of scientific research into the terremare I have selected four typical examples for special description. We have seen that in one, viz. Montale, accumulated débris stood as a clear mound on the surface of the surrounding plain, while that of Gorzano rested on a natural hillock. The Castione deposits also assumed the same form, but in this case the mound was only partially above the plain, the rest being buried in it. The tops of the piles found in its peaty stratum (terra uliginosa) were on an average 3 feet below the level of the present surface of the surrounding plain, and the lowest portion of this bed was a couple of feet still lower. In the fourth example, Casale Zaffanella, there was no mound at all visible, but on examination the remains of the settlement were found to be precisely similar to those of the others, only the mound was completely buried, as it were, in a sea of hardened mud.
The explanation of this will be readily perceived when we remember that the amount of submergence respectively shown in these instances is in the inverse ratio to their distance from the lower parts of the plain and its great water channels. The yearly inundations of the Po and its tributaries extend far and wide, each time leaving a film of mud, by the repetition of which, in the course of ages, the surface of the plain has become considerably elevated. Thus, the increase of silt since the terramara settlement of Casale Zaffanella was founded, amounts to 12½ feet—a depth sufficient to cover the highest part of the mound. It is difficult to say how much this levelling up process is accountable for the scarcity of these stations in the lower parts of the Po valley. That they existed, however, in close proximity to the river is amply proved by those stations at Viadana, as well as one or two others, for example, at Brescello, in the Parmensian district, on the south side of the river.
Distribution.—Formerly the terramara deposits were supposed to be peculiar to the middle reaches of Parma, Reggio, and Modena; but later discoveries have upset this generalisation, as they are now shown to have a much wider distribution, embracing the provinces on both sides of the Po.
