Note 69 — Chapter V
Reading edition
There is another motive for the robbery of a human creature, mentioned only, I think, in the Romance of Thomas the Rhymer, namely, that at certain seasons the foul fiend fetches his fee, or tribute of a living soul, from among the underground folk. Several difficulties arise upon this; but it is needless to discuss them until the motive in question be found imputed elsewhere than in a literary work of the fifteenth century, and ballads derived therefrom.
Since the foregoing note was written my attention has been drawn to the following statement in Lady Wilde, vol. i. p. 70: “Sometimes it is said the fairies carry off the mortal child for a sacrifice, as they have to offer one every seven years to the devil in return for the power he gives them. And beautiful young girls are carried off, also, either for sacrifice or to be wedded to the fairy king.” It is easier to generalize in this manner than to produce documents in proof. And I think I am expressing the opinion of all folklore students when I say that, with all respect for Lady Wilde, I would rather not lay any stress upon her general statements. Indeed, those of anybody, however great an authority, need to be checked by the evidence of particular instances. I await such evidence.
