Of the comparative frequency of industrial remains in the terramara deposits, a correct notion will be got from a study of Dr. Coppi's report of the excavations at Gorzano during the year 1875. In this year there were 274 cubic mètres excavated, covering an area of 180 square mètres; and from this mass of débris there were collected 3,051 objects, of which 173 belonged to the upper or Romano-mediæval stratum, which varied from 1 to 1½ mètres in thickness. The rest of the objects, which came from the under strata, and were reckoned prehistoric, are thus classified:—852 industrial objects, 1,544 remains of vertebrate animals, 285 remains of molluscs, 153 vegetable remains.
The 852 industrial remains are again thus assigned:—
Bronze.—50 objects: viz. eight pins, four axes, 12 daggers, one chisel, two awls, six discs, one spindle-whorl, two fragments of sickles, and 14 diverse bits.
Bone.—80 objects: viz. 38 needles and pins (of which 23 are entire), nine spatulæ, 17 pointers, three chisels, six teeth, one lamina, five awls, and one handle.
Horn.—62 objects: viz. seven small wheels, one cylinder, one comb, two arrow-points, 17 spatulæ, 12 pointers, two awls, three ornaments, two picks, four handles, and 17 diverse pieces.
Stone.—68 objects: viz. two flint knives, two pendants, four spindle-whorls, two discs, four weights, six grinding-stones, one polisher, three flint nodules, four flint flakes, and 30 worked stones.
Terracotta.—585 objects: viz. 494 spindle-whorls ([Fig. 85], No. 17), two cylinders, 12 weights, 68 vases, three covers, five percolators, and one small animal figure.
The bones capable of being determined represented the following animals:—15 oxen, 25 sheep or goats, seven stags, eight roes, 30 pigs, two wild boars, 14 dogs or wolves, one cat, eight birds, one tortoise, and 15 toads.
