The most interesting, and one of the most recently discovered, of these older civilisations, was the AEgean. Its chief centre was Crete, but it spread over many of the neighbouring islands. Its art and its script are so distinctive that we must recognise it as a native development, not a transplantation of Egyptian culture. Its ruins show it gradually emerging from the Neolithic stage about 4000 B.C., when Egyptian commerce was well developed in its seas. Somewhere about 2500 B.C. the whole of the islands seem to have been brought under the Cretan monarchy, and the concentration of wealth and power led to a remarkable artistic development, on native lines. We find in Crete the remains of splendid palaces, with advanced sanitary systems and a great luxuriance of ornamentation. It was this civilisation which founded the centre at Mycenae, on the Greek mainland, about the middle of the second millennium B.C. But our inquiry into the origin of European civilisation does not demand any extensive description of the AEgean culture and its Mycenaean offshoot. It was utterly destroyed between 1500 and 1000 B.C., and this was probably done by the Aryan ancestors of the later Greeks or Hellenes. About the time when one branch of the Aryans was descending upon India and another preparing to rival decaying Babylonia, the third branch overran Europe. It seems to have been a branch of these that swept down the Greek peninsula, and crossed the sea to sack and destroy the centres of AEgean culture. Another branch poured down the Italian peninsula; another settled in the region of the Baltic, and would prove the source of the Germanic nations; another, the Celtic, advanced to the west of Europe. The mingling of this semi-barbaric population with the earlier inhabitants provided the material of the nations of modern Europe. Our last page in the story of the earth must be a short account of its civilisation.
