But that which may have puzzled this matter most, may be, that Vandyke, one of the best portrait painters in most respects ever known, plainly appears not to have had a thought of this kind. For there seems not to be the least grace in his pictures more than what the life chanced to bring before him. There is a print of the Dutchess of Wharton (fig. 52, plate II,) engraved by Van Gunst, from a true picture by him, which is thoroughly divested of every elegance. Now, had he known this line as a principle, he could no more have drawn all the parts of this picture so contrary to it, than Mr. Addison could have wrote a whole spectator in false grammar; unless it were done on purpose. However, on account of his other great excellencies, painters chuse to stile this want of grace in his attitudes, &c. _simplicity_, and indeed they do often very justly merit that epithet. [Illustration: Fig. 52] Nor have the painters of the present times been less uncertain and contradictory to each other, than the masters already mentioned, whatever they may pretend to the contrary: of this I had a mind to be certain, and therefore, in the year 1745, published a frontispiece to my engraved works, in which I drew a serpentine line lying on a painter's pallet, with these words under it, THE LINE OF BEAUTY. The bait soon took; and no Egyptian hierogliphic ever amused more than it did for a time, painters and sculptors came to me to know the meaning of it, being as much puzzled with it as other people, till it came to have some explanation; then indeed, but not till then, some found it out to be an old acquaintance of theirs, tho' the account they could give of its properties was very near as satisfactory as that which a day-labourer who constantly uses the leaver, could give of that machine as a mechanical power. Others, as common face painters and copiers of pictures, denied that there could be such a rule either in art or nature, and asserted it was all stuff and madness; but no wonder that these gentlemen should not be ready in comprehending a thing they have little or no business with. For though the _picture copier_ may sometimes to a common eye seem to vye with the original he copies, the artist himself requires no more ability, genius, or knowledge of nature, than a journeyman-weaver at the goblins, who in working after a piece of painting, bit by bit, scarcely knows what he is about, whether he is weaving a man or a horse, yet at last almost insensibly turns out of his loom a fine piece of tapestry, representing, it may be, one of Alexander's battles painted by Le Brun.
