6. The Honourable John Abercromby maintains that the brachycephalic invaders, or some of them, came at the beginning of the Bronze Age or in the period of transition between the Neolithic Age and the Bronze Age from the neighbourhood of the middle Rhine or from some intermediate district between it and Britain.[1997] Remarking[1998] that ‘the recorded finds of the last hundred years are sufficient to establish the fact that the beaker [or drinking-cup] is the oldest form of fictilia in the Bronze Age of this country’, he argues that the immigrants who introduced the oldest drinking-cups of the kind which Thurnam designated as ‘type β’ must have belonged to a tribe who at one time lived in the valley of the Rhine, because between British and Rhenish specimens of this type ‘there is a substantial agreement’ both in form and ornament, which ‘seems too great to be the result of pure accident’; and he points out[1999] that ‘the type exists not only in the central Rhine, but also near its mouth’, though the intermediate stages cannot be traced. The Rhenish cups belong to the Neolithic Age; and it seems impossible to prove that the earliest British examples were not made before any objects of bronze were manufactured in or introduced into Britain:[2000] but Mr. Abercromby has certainly established a very strong probability in favour of the locality to which he refers their origin.[2001]
The great mistake that has been made in discussing the question is the not uncommon assumption that the brachycephalic immigrants who buried their dead in round barrows arrived in Britain at one time and came from one place. Some of them certainly appeared before the end of the Neolithic Age: others may have introduced bronze implements or ornaments; others doubtless came, in successive hordes, during the course of the Bronze Age. Some of those who belonged to the Grenelle race, who certainly came from Eastern Europe and possibly from Asia,[2002] and whose centre of dispersion was the Alpine region,[2003] may have started from Gaul;[2004] others could have traced their origin to some Rhenish tribe; and I am inclined to believe that those who belonged to the characteristic rugged Round Barrow type crossed over, for the most part, from Denmark or the outlying islands. That the first Celtic-speaking invaders landed in Britain before the end of the Bronze Age I do not deny; and if they came from that part of Gaul which was inhabited by the Celtae, I have no doubt that many of them were brachycephalic. But it is nevertheless certain that among these invaders the dominant element, who were Celtic in blood as well as in speech, and whose physical type was that described by the ancient writers, were not brachycephalic but mesaticephalic or dolichocephalic. And if I am asked where the Celtic skulls of the later British Bronze Age are to be found, I answer, Nowhere: they were reduced to ashes by cremation.[2005]
