(M48) In antiquity the annual practice of hammering a nail into a wall was not confined to Rome. It was observed also at Vulsinii, in Etruria, where the nails thus fixed in the temple of the goddess Nortia served as a convenient means of recording and numbering the years.(230) To Roman antiquaries of a later period it seemed, naturally enough, that such a practice had indeed no other object than that of marking the flight of time in ages when writing was but little used.(231) Yet a little reflection will probably convince us that this, though it was doubtless a useful consequence of the custom, can hardly have been its original intention. For it will scarcely be disputed that the annual observance of the custom cannot be wholly dissociated from its occasional observance in seasons of great danger or calamity, and that whatever explanation we give of the one ought to apply to the other also. Now it is plain that if we start from the annual observance and regard it as no more than a timekeeper or mode of recording the years, we shall never reach an adequate explanation of the occasional observance. If the nails were merely ready reckoners of the years, how could they come to be used as supreme remedies for pestilence, frenzy, and sedition, resorted to by the state in desperate emergencies when all the ordinary resources of policy and religion had failed? On the other hand, if we start from the occasional observance and view it, in accordance with modern analogies, as a rude attempt to dispose of intangible evils as if they were things that could be handled and put away out of sight, we can readily understand how such an attempt, from being made occasionally, might come to be repeated annually for the sake of wiping out all the old troubles and misfortunes of the past year and enabling the community to start afresh, unencumbered by a fardel of ills, at the beginning of a new year. Fortunately we can shew that the analogy which is thus assumed to exist between the Roman custom and modern superstition is not a merely fanciful one; in other words, it can be proved that the Romans, like modern clowns, did believe in the possibility of nailing down trouble, in a literal and physical sense, into a material substance. Pliny tells us that an alleged cure for epilepsy, or the falling sickness, was to drive an iron nail into the ground on the spot which was first struck by the patient’s head as he fell.(232) In the light of the modern instances which have come before us, we can hardly doubt that the cure was supposed to consist in actually nailing the disease into the earth in such a way that it could not get up and attack the sufferer again. Precisely parallel is a Suffolk cure for ague. You must go by night alone to a cross-road, and just as the clock strikes the midnight hour you must turn yourself about thrice and drive a tenpenny nail up to the head into the ground. Then walk away backwards
