We can then imagine our Wiros as a somewhat variable race, with heads which conform to the narrow rather than to the broad type, tall and robust, though probably neither so tall nor so robust as many of the modern Nordics. There is reason for believing them to have been fair, with transparent skins, light hair and grey eyes, though it is likely enough that in colouration, too, there was considerable variation. We may well believe that the extremely fair colouring of the modern Swedes is a later specialisation, due to a few thousand years of life in a northern home, but we shall do well, I would suggest, to think of the original Wiros as blonds rather than brunets, though not necessarily or in all cases possessing an extreme degree of blondness. Such then I would have you picture the Wiros on the steppe, and I would also remind you that many of them seem to have been descendants of the late Aurignacian and Solutrean horse-hunters, and that they may have developed the rudiments of their language in some post-Solutrean time within the Carpathian ring. We have seen reason for believing that a period of drought, occurring some centuries before 3000 /B.C./, drove some of them towards the Baltic. It is possible, though I think improbable, that these may have been the ancestors of the group who use Teutonic speech. I am more inclined, however, to see in them the original speakers of Lithuanian and the Baltic tongues. Whether there was also at this time a move to the east is uncertain. Kurgans are said to stretch to the north-east well into Siberia, but we have insufficient data at present to determine their age or indeed whether they belong to Wiro culture. It is possible, however, that the north-westerly movement was paralleled by one to the north-east, into the Obi basin, and the Wiros may have wandered as far north as Tobolsk, or even to the Arctic Circle. But the great dispersal was about 2200 /B.C./ On this occasion the drought seems to have been more excessive or more prolonged, for it is believed that the steppe was left for awhile uninhabited. That the movements passed east and west is certain, for we find evidence of the abandonment of settled villages both in the Tripolje area and at Anau. With the westerly movement we have dealt at some length; that to the east must now demand our attention.
