The culture of the oldest lake-dwellings appears suddenly in Europe, and its beginnings are exotic in all their essentials. The turbary cattle were quite different from the wild _primigenius_ race of the surrounding regions; and we find no remains of the intermediate forms which should occur if domestication had taken place here. The same is true of the turbary pig. Wild sheep are unknown in northern Europe, and the moufflon of the Mediterranean islands can hardly have been the ancestor of our Swiss flocks, and is very possibly descended from domesticated ancestors which reverted to wild life. Something very similar may be said of our oldest cereals, wheat and barley. We must evidently turn eastward or southward to find the cradle of the whole culture. Even if it came partly from Italy, it could hardly have developed there. Egypt may have made contributions, but mostly at a later date. We naturally turn first to Asia, the great centre of mammalian evolution, probably the oldest seat of cattle-raising and agriculture, cradle of man and centre of his earliest development. The true Neolithic cultures in northern Europe can hardly be older than about 6000 B. C.; the lake-dwellings are probably far younger. We must first inquire into the location, age, and character of the oldest agriculture in nearer Asia, where great discoveries have been made during the last twenty years. We naturally turn first to Babylonia. Under the temple of Bel, at Nippur, was an immense platform constructed of sun-dried bricks, most of them stamped with the name of Sargon or of Naram Sin. The date of Sargon seems still uncertain; many historians place it at 2800 B. C.; others, and apparently most archæologists, like Obermaier, still hold to the old date, 3750 B. C.[70] Without any attempt to decide this question, we will hold in this chapter to the older date; and believers in the latter date can subtract 1,000 from our figures for earlier times, though this does not apply to Pumpelly's estimates. Says Delitzsch[71] of this mound: "In the deepest layers of these remains, or what amounts to the same, back many centuries beyond the fifth millennium, everywhere interesting and valuable remains of human civilization come to light, fragments of vessels of copper, bronze, and clay, a quantity of earthenware so beautifully lacquered in red and black that we might consider them of Greek origin, or at least influenced by Greek art, had they not been found eight metres deep under Naram Sin's pavement." Here we find the Bronze period, or possibly late Copper, before 5000 B. C. A city with a high and complex culture had already arisen. No one believes that the culture could have originated in the rank, almost untamable, primitive jungle of Mesopotamia. Its beginnings must be sought elsewhere and earlier. But the age and character of Babylonian civilization encourage one to seek further in western Asia.
