["How great is the power of counterfeiting pain: Caelius has ceased to feign the gout; he has got it."--Martial, Ep., vii. 39, 8.] I think I have read somewhere in Appian a story like this, of one who to escape the proscriptions of the triumvirs of Rome, and the better to be concealed from the discovery of those who pursued him, having hidden himself in a disguise, would yet add this invention, to counterfeit having but one eye; but when he came to have a little more liberty, and went to take off the plaster he had a great while worn over his eye, he found he had totally lost the sight of it indeed, and that it was absolutely gone. 'Tis possible that the action of sight was dulled from having been so long without exercise, and that the optic power was wholly retired into the other eye: for we evidently perceive that the eye we keep shut sends some part of its virtue to its fellow, so that it will swell and grow bigger; and so inaction, with the heat of ligatures and, plasters, might very well have brought some gouty humour upon the counterfeiter in Martial. Reading in Froissart the vow of a troop of young English gentlemen, to keep their left eyes bound up till they had arrived in France and performed some notable exploit upon us, I have often been tickled with this thought, that it might have befallen them as it did those others, and they might have returned with but an eye a-piece to their mistresses, for whose sakes they had made this ridiculous vow. Mothers have reason to rebuke their children when they counterfeit having but one eye, squinting, lameness, or any other personal defect; for, besides that their bodies being then so tender, may be subject to take an ill bent, fortune, I know not how, sometimes seems to delight in taking us at our word; and I have heard several examples related of people who have become really sick, by only feigning to be so. I have always used, whether on horseback or on foot, to carry a stick in my hand, and even to affect doing it with an elegant air; many have threatened that this fancy would one day be turned into necessity: if so, I should be the first of my family to have the gout. But let us a little lengthen this chapter, and add another anecdote concerning blindness. Pliny reports of one who, dreaming he was blind, found himself so indeed in the morning without any preceding infirmity in his eyes. The force of imagination might assist in this case, as I have said elsewhere, and Pliny seems to be of the same opinion; but it is more likely that the motions which the body felt within, of which physicians, if they please, may find out the cause, taking away his sight, were the occasion of his dream.
