Thunderbolts
by
All the world over, this simple and easy belief, that the buried stone axe is a thunderbolt, exists among Europeans and savages alike. In the West of England, the labourers will tell you that the thunder-axes they dig up fell from the sky. In Brittany, says Mr. Tylor, the old man who mends umbrellas at Carnac, beside the mysterious stone avenues of that great French Stonehenge, inquires on his rounds for pierres de tonnerre, which of course are found with suspicious frequency in the immediate neighbourhood of prehistoric remains. In the Chinese Encyclopaedia we are told that the ‘lightning stones’ have sometimes the shape of a hatchet, sometimes that of a knife, and sometimes that of a mallet. And then, by a curious misapprehension, the sapient author of that work goes on to observe that these lightning stones are used by the wandering Mongols instead of copper and steel. It never seems to have struck his celestial intelligence that the Mongols made the lightning stones instead of digging them up out of the earth. So deeply had the idea of the thunderbolt buried itself in the recesses of his soul, that though a neighbouring people were still actually manufacturing stone axes almost under his very eyes, he reversed mentally the entire process, and supposed they dug up the thunderbolts which he saw them using, and employed them as common hatchets. This is one of the finest instances on record of the popular figure which grammarians call the hysteron proteron, and ordinary folk describe as putting the cart before the horse. Just so, while in some parts of Brazil the Indians are still laboriously polishing their stone hatchets, in other parts the planters are digging up the precisely similar stone hatchets of earlier generations, and religiously preserving them in their houses as undoubted thunderbolts. I have myself had pressed upon my attention as genuine lightning stones, in the West Indies, the exquisitely polished greenstone tomahawks of the old Carib marauders. But then, in this matter, I am pretty much in the position of that philosophic sceptic who, when he was asked by a lady whether he believed in ghosts, answered wisely, ‘No, madam, I have seen by far too many of them.’
One of the finest accounts ever given of the nature of thunderbolts is that mentioned by Adrianus Tollius in his edition of ‘Boethius on Gems.’ He gives illustrations of some neolithic axes and hammers, and then proceeds to state that in the opinion of philosophers they are generated in the sky by a fulgureous exhalation (whatever that may look like) conglobed in a cloud by a circumfixed humour, and baked hard, as it were, by intense heat. The weapon, it seems, then becomes pointed by the damp mixed with it flying from the dry part, and leaving the other end denser; while the exhalations press it so hard that it breaks out through the cloud, and makes thunder and lightning. A very lucid explanation certainly, but rendered a little difficult of apprehension by the effort necessary for realising in a mental picture the conglobation of a fulgureous exhalation by a circumfixed humour.
One would like to see a drawing of the process, though the sketch would probably much resemble the picture of a muchness, so admirably described by the mock turtle. The excellent Tollius himself, however, while demurring on the whole to this hypothesis of the philosophers, bases his objection mainly on the ground that, if this were so, then it is odd the thunderbolts are not round, but wedge-shaped, and that they have holes in them, and those holes not equal throughout, but widest at the ends. As a matter of fact, Tollius has here hit the right nail on the head quite accidentally; for the holes are really there, of course, to receive the haft of the axe or hammer. But if they were truly thunderbolts, and if the bolts were shafted, then the holes would have been lengthwise, as in an arrowhead, not crosswise, as in an axe or hammer. Which is a complete reductio ad absurdum of the philosophic opinion.
