They were entering upon a new phase in human culture, the Neolithic phase (New Stone Age) as distinguished from the Palæolithic (Old Stone) phase of the Cro-Magnards, the Grimaldi people, the Azilians and their like. [1] Slowly these Neolithic people spread over the warmer parts of the world; and the arts they had mastered, the plants and animals they had learnt to use, spread by imitation and acquisition even more widely than they did. By 10,000 B.C., most of mankind was at the Neolithic level. Now the ploughing of land, the sowing of seed, the reaping of harvest, threshing and grinding, may seem the most obviously reasonable steps to a modern mind just as to a modern mind it is a commonplace that the world is round. What else could you do? people will ask. What else can it be? But to the primitive man of twenty thousand years ago neither of the systems of action and reasoning that seem so sure and manifest to us to-day were at all obvious. He felt his way to effectual practice through a multitude of trials and misconceptions, with fantastic and unnecessary elaborations and false interpretations at every turn. Somewhere in the Mediterranean region, wheat grew wild; and man may have learnt to pound and then grind up its seeds for food long before he learnt to sow. He reaped before he sowed. And it is a very remarkable thing that throughout the world wherever there is sowing and harvesting there is still traceable the vestiges of a strong primitive association of the idea of sowing with the idea of a blood sacrifice, and primarily of the sacrifice of a human being. The study of the original entanglement of these two things is a profoundly attractive one to the curious mind; the interested reader will find it very fully developed in that monumental work, Sir J. G. Frazer’s _Golden Bough_. It was an entanglement, we must remember, in the childish, dreaming, myth-making primitive mind; no reasoned process will explain it. But in that world of 12,000 to 20,000 years ago, it would seem that whenever seed time came round to the Neolithic peoples there was a human sacrifice. And it was not the sacrifice of any mean or outcast person; it was the sacrifice usually of a chosen youth or maiden, a youth more often who was treated with profound deference and even worship up to the moment of his immolation. He was a sort of sacrificial god-king, and all the details of his killing had become a ritual directed by the old, knowing men and sanctioned by the accumulated usage of ages.
