Note 9 — Chapter II · The Fairies’ Revenge

The shorter versions given by Glasynys are probably more nearly given as he heard them, than the longer ones, which may be suspected of having been a good deal spun out by him; but there is probably very little in any of them of his own invention, though the question whence he got his materials in each instance may be difficult to answer. In one this is quite clear, though he does not state it, namely the story of the sojourn of Elfod the Shepherd in Fairyland, as given in Cymru Fu, p. 477: it is no other than a second or third-hand reproduction of that recorded by Giraldus concerning a certain Eliodorus, a twelfth-century cleric in the diocese of St. David’s9. But the longest tale published by Glasynys is the one about a mermaid: see Cymru Fu, pp. 434–44. Where he got this from I have not been able to find out, but it has probably been pieced together from various sources. I feel sure that some of the materials at least were Welsh, besides the characters known to Welsh mythology as Nefyđ Naf Neifion, Gwyn ab Nuđ, Gwydion ab Dôn, Dylan, and Ceridwen, who have been recklessly introduced into it.
