The Blue Fairy Book, the first of Andrew Lang’s folk and fairy tale collections, was published in 1889. You’ll find the monstrous three-headed Red Etin in there searching for a young man who “had not been long in his hidy-hole before the awful Etin came in; and no sooner was he in than he was heard crying:
‘Snouk but and snouk ben,
I find the smell of an earthly man;
Be he living, or be he dead,
His heart this night shall kitchen my bread.'”
Giants seem to have a fondness for reciting how they’ll go about dining on people, don’t they?
