And in this light I hope my prints will be consider'd, and that the figures referr'd to in them will never be imagined to be placed there by me as examples themselves, of beauty or grace, but only to point out to the reader what sorts of objects he is to look for and examine in nature, or in the works of the greatest masters. My figures, therefore, are to be consider'd in the same light, with those a mathematician makes with his pen, which may convey the idea of his demonstration, tho' not a line in them is either perfectly straight, or of that peculiar curvature he is treating of. Nay, so far was I from aiming at grace, that I purposely chose to be least accurate, where most beauty might be expected, that no stress might be laid on the figures to the prejudice of the work itself. For I must confess, I have but little hopes of having a favourable attention given to my design in general, by those who have already had a more fashionable introduction into the mysteries of the arts of painting, and sculpture. Much less do I expect, or in truth desire, the countenance of that set of people, who have an interest in exploding any kind of doctrine, that may teach us to see with our own eyes.
