Towards the close of the prehistoric age the taste for ornament becomes very marked, but that ornament is always of the kind which we call geometric. Hardly a single decorative motive is taken from the vegetable world. Like the rude efforts of the cave-men, this decoration proves that those by whom it was imagined and who frequently employed it with such happy results, were not contented with bare utility, but, so far as they could, sought after beauty. A secret instinct worked in them and inspired them with the desire to give some appearance of elegance to the objects which they had in daily use. This geometrical style of decoration prevailed all over central Europe until, in the first place, the movements of commerce with Greece and Etruria, and secondly the Roman conquest, introduced the methods of classic art. From what we have said, it will be seen that we could not have passed over in silence this system of ornamentation; but we shall again find it in our path when we come to treat of that prehistoric Greece which preceded by perhaps two or three centuries the Greece of Homer. By the help of the discoveries which have been lately made in the Troad, at Mycenæ, and in other ancient sites, we shall study the works produced by the ancestors of the Greeks before they went to school to the nations of the East. But even with the discoveries which carry us farthest back, we only reach the end of the period in question, when maritime commerce had already brought to the islands and the mainland of Greece objects of Egyptian, Phœnician or Chaldaic manufacture, but before those objects were sufficiently numerous or the relations with those countries sufficiently intimate to produce any great effect upon the habits of native workmen. Among the deposits to which we have alluded, it is generally possible to distinguish those works which are of foreign origin; and such works excluded, it is easy to form a sufficiently accurate general idea of the art practised by the forefathers of the historic Greeks--by the Pelasgians, to use a conventional term. So long as it was left to its own inspiration, Pelasgic art did not differ, in its general characteristics, from that of the various peoples spread over the continent of Europe, and still practised for centuries after the dawn of Greek civilization in the great plains to the north of the Alps and the Danube. Its guiding spirit and its motives are similar. There is the same richness, or rather the same poverty, the same combinations produced by a small number of never-changing linear elements. One would say that from the shores of the great ocean and the Baltic to those of the Mediterranean, all the workmen laboured for the same masters. Struck by this resemblance, or rather uniformity, one of the most eminent of German archæologists, Herr Conze, has proposed that this kind of ornament shall be called Indo-European; he sees, in the universality
