Let us, at the risk of a slight repetition, be perfectly clear upon one point. The _Iliad_ does not give us the primitive neolithic life of that Aryan region of origin; it gives us that life already well on the move towards a new state of affairs. The primitive neolithic way of living, with its tame and domesticated animals, its pottery and cooking, and its patches of rude cultivation, we have sketched in Chapter XI. We have already discussed in § 4 of Chapter XIII the probability of a widespread _heliolithic_ culture, a sort of sub-civilization, very like the Polynesian and Indonesian life of a hundred years ago, an elaboration of the earlier Neolithic stage. Between 15,000 and 6000 B.C. the neolithic way of living had spread with the forests and abundant vegetation of the Pluvial Period, over the greater part of the old world, from the Niger to the Hwang-ho and from Ireland to the south of India. Now, as the climate of great portions of the earth was swinging towards drier and more open conditions again, the primitive neolithic life was developing along two divergent directions. One was leading to a more wandering life, towards at last a constantly migratory life between summer and winter pasture, which is called NOMADISM; the other, in certain sunlit river valleys, was towards a water-treasuring life of irrigation, in which men gathered into the first towns and made the first CIVILIZATION. The nature and development of civilization we shall consider more fully in the next chapter, but here we have to note that the Greeks, as the _Iliad_ presents them, are neither simple neolithic nomads, innocent of civilization, nor are they civilized men. They are primitive nomads in an excited state, because they have just come upon civilization, and regard it as an opportunity for war and loot.[96] So far they are exceptional and not representative. But our interest in them in this chapter is not in their distinctively Greek and predatory aspect, but in what they reveal of the ordinary northward life from which they are coming. These early Greeks of the _Iliad_ are sturdy fighters, but without discipline--their battles are a confusion of single combats. They have horses, but no cavalry; they use the horse, which is a comparatively recent addition to Aryan resources, to drag a rude fighting chariot into battle. The horse is still novel enough to be something of a terror in itself. For ordinary draught purposes, as in the quotation from the _Iliad_ we have just made, oxen were employed. The only priests of these Aryans are the keepers of shrines and sacred places. There are chiefs, who are heads of families and who also perform sacrifices, but there does not seem to be much mystery or sacramental feeling in their religion. When the Greeks go to war, these heads and elders meet in council and appoint a king, whose powers are very loosely defined. There are no laws, but only customs; and no exact standards of conduct.
