The reason why gentlemen, who have been inquisitive after knowledge in pictures, have their eyes less qualified for our purpose, than others, is because their thoughts have been entirely and continually employ'd and incumber'd with considering and retaining the various _manners_ in which pictures are painted, the histories, names, and characters of the masters, together with many other little circumstances belonging to the mechanical part of the art; and little or no time has been given for perfecting the ideas they ought to have in their minds, of the objects themselves in nature: for by having thus espoused and adopted their first notions from nothing but _imitations_, and becoming too often as bigotted to their faults, as their beauties, they at length, in a manner, totally neglect, or at least disregard the works of nature, merely because they do not tally with what their minds are so strongly prepossess'd with. Were not this a true state of the case, many a reputed capital picture, that now adorns the cabinets of the curious in all countries, would long ago have been committed to the flames: nor would it have been possible for the Venus and Cupid, represented by the figure [under Fig. 49 T p. I], to have made its way into the principal apartment of a palace. [Illustration: Fig. under Fig. 49] It is also evident that the painter's eye may not be a bit better fitted to receive these new impressions, who is in like manner too much captivated with the works of art; for he also is apt to pursue the shadow, and drop the substance. This mistake happens chiefly to those who go to Rome for the accomplishment of their studies; as they naturally will, without the utmost care, take the infectious turn of the connoisseur, instead of the painter: and in proportion as they turn by those means bad proficients in their own arts, they become the more considerable in that of a connoisseur. As a confirmation of this seeming paradox, it has ever been observ'd at all auctions of pictures, that the very worst painters sit as the most profound judges, and are trusted only, I suppose, on account of their _disinterestedness_.
