The Coblynau are always given the form of dwarfs, in the popular fancy; wherever seen or heard, they are believed to have escaped from the mines or the secret regions of the mountains. Their homes are hidden from mortal vision. When encountered, either in the mines or on the mountains, they have strayed from their special abodes, which are as spectral as themselves. There is at least one account extant of their secret territory having been revealed to mortal eyes. I find it in a quaint volume (of which I shall have more to say), printed at Newport, Monmouthshire, in 1813.[19] It relates that one William Evans, of Hafodafel, while crossing the Beacon Mountain very early in the morning, passed a fairy coal mine, where fairies were busily at work. Some were cutting the coal, some carrying it to fill the sacks, some raising the loads upon the horses' backs, and so on; but all in the completest silence. He thought this 'a wonderful extra natural thing,' and was considerably impressed by it, for well he knew that there really was no coal mine at that place. He was a person of 'undoubted veracity,' and what is more, 'a great man in the world--above telling an untruth.'
