In all the houses and in every room of each were found beneath the tufa burying them masses of lava and volcanic scoriae, forming a most eloquent witness of the cause of their destruction. Near one of the houses of Therasia is a little cylindrical structure, about three feet high; which cannot have been a well, as it rests directly on impermeable lava, and was certainly not a cistern, as it is too small for that. May it, as some think, have been an altar? We cannot tell, and though the religious sentiment was probably no more absent among these primitive races than it is among the barbarous peoples of our own day, it does not do to express an opinion in the absence of positive proof. Successive excavations have yielded a number of objects which throw a new light upon the manners and customs of the inhabitants. Terra-cotta vases are more numerous than anything else (Fig. 88), and among them preponderate large yellow vessels capable of holding about one hundred quarts. Most of them have a clumsy brim, and a rough attempt has been made at ornamentation by the potter with his fingers on the damp clay. Other vases of finer clay, colored red or yellow, are covered with ornaments and graceful arabesques; the garlands of fruit and flowers are often of remarkably beautiful workmanship. Cups with well-shaped rounded handles, made of some kind of red ferruginous earth, others of gray material, were picked up in all the houses. These various vessels were used for many different purposes; some to cook food, the marks of the hearth being still on them, whilst others retained some of the chopped straw with which the domestic animals had evidently been fed. The most curious of all are those which are supposed to represent a woman; the front part projecting and surmounted by a narrow neck bent backwards, with two brown prominences supposed to stand for breasts, and dots round the upper part representing a necklace, while ear-rings are indicated by elliptical bands of different colors. We shall have to refer again to these curious vases when we speak of the discoveries made at Troy; we need only add now that the pottery found at Santorin differs completely, alike in form and ornamentation, from the Greek, Phœnician, and Etruscan specimens, of which the museums of Europe contain so many. They are evidently therefore not of foreign origin, but of native manufacture. The absence of clay in the island of Santorin has thrown some doubt on this, however, but the researches of M. Fouqué have revealed the former existence of a large valley, at the base of the principal cone, which valley ran down to the sea-shore near the island of Aspronisi; and in which probably was found the clay which the potters of the district soon learned to turn to account.
