And here we shall of necessity be led to open a new vein of knowledge, which if it hath been discovered, hath not, to our remembrance, been wrought on by any antient or modern writer. This vein is no other than that of contrast, which runs through all the works of the creation, and may probably have a large share in constituting in us the idea of all beauty, as well natural as artificial: for what demonstrates the beauty and excellence of anything but its reverse? Thus the beauty of day, and that of summer, is set off by the horrors of night and winter. And, I believe, if it was possible for a man to have seen only the two former, he would have a very imperfect idea of their beauty.

But to avoid too serious an air; can it be doubted, but that the finest woman in the world would lose all benefit of her charms in the eye of a man who had never seen one of another cast? The ladies themselves seem so sensible of this, that they are all industrious to procure foils: nay, they will become foils to themselves; for I have observed (at Bath particularly) that they endeavour to appear as ugly as possible in the morning, in order to set off that beauty which they intend to show you in the evening.

Most artists have this secret in practice, though some, perhaps, have not much studied the theory. The jeweller knows that the finest brilliant requires a foil; and the painter, by the contrast of his figures, often acquires great applause.

A great genius among us will illustrate this matter fully. I cannot, indeed, range him under any general head of common artists, as he hath a title to be placed among those

Inventas qui vitam excoluere per artes.
Who by invented arts have life improved.

I mean here the inventor of that most exquisite entertainment, called the English Pantomime.

This entertainment consisted of two parts, which the inventor distinguished by the names of the serious and the comic. The serious exhibited a certain number of heathen gods and heroes, who were certainly the worst and dullest company into which an audience was ever introduced; and (which was a secret known to few) were actually intended so to be, in order to contrast the comic part of the entertainment, and to display the tricks of harlequin to the better advantage.

This was, perhaps, no very civil use of such personages: but the contrivance was, nevertheless, ingenious enough, and had its effect. And this will now plainly appear, if, instead of serious and comic, we supply the words duller and dullest; for the comic was certainly duller than anything before shown on the stage, and could be set off only by that superlative degree of dulness which composed the serious. So intolerably serious, indeed, were these gods and heroes, that harlequin (though the English gentleman of that name is not at all related to the French family, for he is of a much more serious disposition) was always welcome on the stage, as he relieved the audience from worse company.

Judicious writers have always practised this art of contrast with great success. I have been surprized that Horace should cavil at this art in Homer; but indeed he contradicts himself in the very next line:

For we are not here to understand, as perhaps some have, that an author actually falls asleep while he is writing. It is true, that readers are too apt to be so overtaken; but if the work was as long as any of Oldmixon, the author himself is too well entertained to be subject to the least drowsiness. He is, as Mr. Pope observes,

Sleepless himself to give his readers sleep.

To say the truth, these soporific parts are so many scenes of serious artfully interwoven, in order to contrast and set off the rest; and this is the true meaning of a late facetious writer, who told the public that whenever he was dull they might be assured there was a design in it.
