In 1691 Robert Kirk, minister of Aberfoyle in the Scottish Highlands, wrote down what his parishioners believed about the subterranean inhabitants: their bodies of condensed air, their dwellings in the hills, the hurts they inflict and their cures, and the second sight by which some people saw them. Andrew Lang’s 1893 edition adds an introduction, notes, and the legend that Kirk himself was taken by the fairies.
