Professor Myres has argued for a very wide distribution of these people, in fact from the Elbe to Tobolsk, and southwards to Bosnia and Thrace.[200] Some of these extensions seem, as we shall see, to date from a later period, and during the time which we are discussing, roughly the period of Hissarlik II., the bulk of them seem to have been restricted to the steppe regions east of the Dnieper, though they roamed the belt of parkland lying to the north, and perhaps even penetrated the dense woodland beyond. How far they had extended eastward is uncertain, but, as we shall see in the next chapter, their more distant excursions in this direction may well have been later.
We know something of their physical type. Bogdanov tells us that they were a robust race, with a large and long head, an elongated face, and, according to some examples, with hair more or less fair.[201] The colour of the hair has been disputed, as there is a tendency for hair in graves to become pale. The cranial index is not quite certain. Sergi states that it varies from 65 to 81,[202] but it seems likely that among his collection of kurgan skulls are some of other types. Bogdanov tells us that in the kurgans to the west of the area several broad skulls occur, but with less robust skeletons, and the average index is higher. This may be due to admixture with Alpine or Beaker types. In the north, too, as one approaches the middle valley of the Volga, the broad type appears also; in this case I have suggested that it is due to admixture with a Mongoloid type which was already occupying this region.[203] From the kurgans at Souja,[204] in the government of Kursk, where the steppe lands reach further north than elsewhere, came twenty-three skulls which showed singular uniformity; nineteen of these were markedly long headed, and the remainder, belonging to three women and a child, only a trifle less so. It is possible that a considerable variation of head-form existed among these people, especially on the outskirts of their region, where they seem to have come into contact with more broad-headed neighbours. But Bogdanov is probably right in concluding that the pure type was a long-headed one, though the skulls seem not to have been so narrow as was frequently the case among the Mediterranean peoples of the west. Normally the length-breadth index seems to have varied from 73 to 76 though both higher and lower indices have sometimes been found.
The most striking feature about this people is the custom of covering the skeleton, or the body, with red ochre.[205] It has been suggested that this arose from the body being buried in clothes and cap of skin, deeply impregnated with this pigment. This custom is widespread, and, as we have seen, was not uncommon in the upper palæolithic age, being found at the beginning of the Aurignacian period in the case of the Grimaldi skeletons found buried in the Grotte des enfants. We seem here to be in the presence of the survival of a custom which dates from the times of Aurignac.
It will be remembered that during the closing phases of the Aurignacian period the Combe Capelle type makes its appearance in western Europe, and about the same time arrived the horse, which was hunted for food. A little later, when steppe conditions had become better established in the west, we have the great Solutrean invasion which drove the artistes of the Dordogne to the Pyrenees. The Combe Capelle type seems to have been predominant during this period, and the Brünn skeletons, one of which was of this type, were covered with red ochre.[206] As the climate deteriorated, and tundra conditions prevailed, the Solutrean invaders departed, apparently to the east.
Until a large number of the skulls of our steppe-folk, found in the kurgans, can be compared with the relatively few crania of the Combe Capelle type which have survived from the upper palæolithic age, it would be dangerous to come to any conclusion, but the evidence cited above makes it reasonable to suggest that perhaps the long-headed hunters of the horse, with their fine laurel-leaf spears, may have retreated to the steppe lands of South Russia and Turkestan, and there converted the animal which they had hunted and ate into a means whereby they could roam with greater ease and rapidity over the grassy plains. The subjugation of the horse would have rendered easier the domestication of cattle, which in turn changed them from hippophagists to beef-eaters. Their robustness and long-headedness, combined with their roaming instincts and devotion to the horse, which will become clearer as we proceed, have convinced me that we are here dealing with that tall, fair, long-headed type, now dominant in northern Europe, which we term the Nordic race.[207]
CHAPTER VI
MANY INVASIONS
THAT large tracts of Asia have been subject to a gradual process of desiccation has been made clear to us by the reports of the successive explorations of Sir Aurel Stein, who has shown us that regions, which are now uninhabited desert, once held a flourishing population. It has been suggested by Ellsworth Huntington,[208] who accompanied the Pumpelly expedition to Turkestan, that the process of desiccation has been neither continuous nor progressive, but has been subject to intermittent action and the alternation of dry and wet periods. The evidence which he has adduced of the rise and fall of the level of the Caspian sea seems to bear out his thesis, which has been further strengthened by his later observations in Palestine and on the shores of the Dead Sea.[209]
It is part of Ellsworth Huntington’s hypothesis that during these periods of drought, or light precipitation, the population of the steppe lands, which had grown in numbers during the previous years of heavier rainfall, have found it difficult to obtain adequate pasturage for their flocks and herds, and have in consequence dispersed to more favoured regions. To this he attributes the great raids from the steppe and desert into the more fertile zones adjoining them, which have been so marked a feature in the history of the Near East. He points out that a relatively small diminution of rainfall may make all the difference between a sufficient and inadequate crop of grass, and should the crop be insufficient, the flocks and herds, the sole means of support for the steppe-folks, would inevitably perish unless driven to moister regions. How serious even one dry year may be has recently been brought home to us by the Russian famine in 1921.
