Note 21 — Chapter I · The Stone Age: its Duration and its Place in Time.

In Germany we are shown Donner-Keile, in Alsace Dormer-Axt, in Holland Donner-Beitels, in Denmark Tordensteen, in Norway Tordenkeile, in Sweden Thorsoggar, Thor having been the god of thunder amongst northern nations; while with the Celts21 the Mengurun, in Asia Minor the Ylderim-tachi, in Japan the Rai-fu-seki-no-rui, in Roussillon the Pedrus de Lamp, and in Andalusia the Piedras de Rayo have the same signification. The inhabitants of the Mindanao islands call these stones the teeth of the thunder animal, and the Japanese the teeth of the thunder.22 In Cambodia, worked stones, celts, adzes, and gouges or knives, are known as thunder stones. A Chinese emperor, who lived in the eighth century of our era, received from a Buddhist priest some valuable presents which the donors said had been sent by the Lord of Heaven, amongst which were two flint hatchets called loui-kong, or stones of the god of thunder. In Brazil we meet with the same idea in the name of corsico, or lightnings, given to worked flints; whilst in Italy, by all exception almost unique, they are called lingue san Paolo.
