Before dealing with Greek vases in further detail, it may be as well to say something of the circumstances under which, and the localities in which, they have been discovered. And further, we must clearly define the limits of our subject, both historically and geographically. (1) =Historical.=—It may seem somewhat paradoxical to doubt whether the primitive pottery found on Greek soil ought, strictly speaking, to be called Greek. In a succeeding chapter we shall have occasion to touch upon the question of the ethnological origin of this pottery, which, in the opinion of some authorities, is not the product of Greeks as we understand the term, but of some Oriental nation, such as the Phoenicians. It is, however, enough for our present purpose that it has been found on Greek soil, and that it forms a stage which we cannot omit from a study of the development of Greek pottery, seeing that its influence can be plainly traced on later fabrics. Turning to the other limit of the subject, we find that nearly all the latest vases, belonging to the period of the Decadence, were manufactured in Southern Italy or Etruria. But nearly all bear so unmistakably the stamp of Greek influence, however degenerate and obscured, that we can only regard them as made by Greek artists settled in the colonies of Magna Graecia, or at any rate by native workers in direct imitation of the Greeks. We may roughly define our historical limits as from 2500 B.C., the approximate age of the early pottery of Crete, Cyprus, and Hissarlik, down to 200 B.C., when the manufacture of painted vases came to an end under the growing dominion of Rome. It was formerly supposed that the senatorial edict of 186 B.C., forbidding the performance of Bacchanalian ceremonies in Italy, was the means of putting an end to this industry, but this is hardly borne out by facts; it rather died a natural death owing to the growing popularity of relief-work both in terracotta and in metal (see Chapters XI. and XXII.).
