And again in Percy’s Reliques of Ancient Poetry, vol. iii., p. 171, are these remarks:—
“It is well known that our Saxon ancestors, long before they left their German forests, believed in the existence of a kind of diminutive demons, or middle species between men and spirits, whom they called Duergar, or Dwarfs, and to whom they attributed wonderful performances, far exceeding human art.”
Pennant, in his Tour in Scotland, 1772, pp. 55-56, when describing the collieries of Newcastle, describes the Knockers thus:—
“The immense caverns that lay between the pillars exhibited a most gloomy appearance. I could not help enquiring here after the imaginary inhabitant, the creation of the labourer’s fancy,
The swart Fairy of the mine;
and was seriously answered by a black fellow at my elbow that he really had never met with any, but that his grandfather had found the little implements and tools belonging to this diminutive race of subterraneous spirits. The Germans believed in two species; one fierce and malevolent, the other a gentle race, appearing like little old men, dressed
like the miners, and not much above two feet high; these wander about the drifts and chambers of the works, seem perpetually employed, yet do nothing. Some seem to cut the ore, or fling what is cut into vessels, or turn the windlass, but never do any harm to the miners, except provoked; as the sensible Agricola, in this point credulous, relates in his book, de Animantibus Subterraneis.”
Jamieson, under the word Farefolkis, writes:—“Besides the Fairies, which are more commonly the subject of popular tradition, it appears that our forefathers believed in the existence of a class of spirits under this name that wrought in the mines;” and again, quoting from a work dated 1658, the author of which says:—
“In northerne kingdomes there are great armies of devils that have their services which they perform with the inhabitants of these countries, but they are most frequent in rocks and mines, where they break, cleave, and make them hollow; which also thrust in pitchers and buckets, and carefully fit wheels and screws, whereby they are drawn upwards; and they show themselves to the labourers, when they list, like phantoms and ghosts.”
The preceding quotations from Pennant and Jamieson correspond with the Welsh miners’ ideas of the Coblynau, or Knockers. There is a difficulty in tracing to their origin these opinions, but, on the whole, I am strongly inclined to say that they have come down to modern times from that remote period when cave-men existed as a distinct people.
