In this county, as also in the contiguous parts of Staffordshire, a barrow is popularly known as a “low,” from the Anglo-Saxon _hlaew_, a small hill, heap, or mound, a word which is a frequent component in the place-names, as in Ward_low_, Blake_low_, etc. The conspicuous barrows at these and many other places so named, leave little room for doubt that they are accountable for the names, and that when absent the names may be regarded as evidence for their former existence. Whether the evidence in the case of hills, so many of the names of which in the Peak end in _low_, is of the same value is not so clear, as the hill itself may have been regarded as a “low” on a large scale. But it is well known that Neolithic and Bronze man had a decided penchant for burying his dead on the tops and brows of hills, as the pimple-like profile of many a barrow in such situations in the Peak amply proves. It may well have been, then, that the name by which a “low” on a hill was known has become transferred to the hill itself. It is impossible to estimate the number of these ancient burial-mounds in Derbyshire. The experienced eye will often detect on the moors the slight rise on the surface which may represent one, unmarked on the Ordnance Survey, and unrecognised as of possible archæological interest. The large number of _low_ names, where no traces of these mounds are now to be seen, indicates that many have disappeared, as also does the occasional chance discovery of a cist or a cinerary urn where nothing on the surface indicated an interment. The number of prehistoric burial places (the Roman and post-Roman do not come within the scope of this article) which have been discovered in the county and _described_ is little short of 300. [Illustration: Fig. 1.—Plan and Section of Chambered Tumulus, Five Wells, Derbyshire.] The first impression that the literature of these remains gives rise to is their great diversity, a diversity which the reader will not unnaturally associate with differences of age or of race, or of both combined; but he will soon find their classification a difficult task. Very few of those which have been explored were in a reasonably perfect condition to begin with, and then the explorations have often been insufficient, and the descriptions vague and inexact. In spite of these drawbacks, however, the Derbyshire barrows are susceptible of satisfactory classification into three main divisions: (1) a small number containing megalithic chambers, and with general consent assigned to the Neolithic Age; (2) a large and varied number which belong to the Bronze Age; and (3) a few which are of later age, some of which certainly synchronize with the Roman occupation. These groups, it should be mentioned, merge into one another by transitional characters, and there is a residue which, from insufficient data, cannot be assigned to any particular class.
