I know not how further to prove this matter than by appealing to the reader's eye, and common observation, as before. The Antinous being allowed to have the justest proportion possible, let us see what addition, upon the principle of quantity, can be made to it, without taking away any of its beauty. If we imagine an addition of dimensions to the head, we shall immediately conceive it would only deform--if to the hands or feet, we are sensible of something gross and ungenteel,--if to the whole lengths of the arms, we feel they would be dangling and aukward--if by an addition of length or breadth to the body, we know it would appear heavy and clumsy--there remains then only the _neck_, with the _legs_ and _thighs_ to speak of; but, to these we find, that not only certain additions may be admitted without causing any disagreeable effect, but that thereby _greatness_, the last perfection as to proportion, is given to the human form; as is evidently express'd in the Apollo: and may still be further confirmed by examining the drawings of Parmigiano, where these particulars are seen in excess; yet on this account his works are said, by all true connoisseurs, to have an inexpressible greatness of taste in them, though otherwise very incorrect. Let us now return to the two general ideas we set out with at the beginning of this chapter, and recollect that under the first, on surface, I have shewn in what manner, and how far human proportion is measureable, by varying the contents of the body, conformable to the given proportion of two lines. And that under the second and more extensive general idea of form, as arising from fitness for movement, &c. I have endeavour'd to explain, by every means I could devise, that every particular and minute dimension of the body, should conform to such purposes of movement, &c. as have been first properly considered and determined: on which conjunctively, the true proportion of every character must depend; and is found so to do, by our joint-sensation of bulk and motion. Which account of the proportion of the human body, however imperfect, may possibly stand its ground, till one more plausible shall be given. As the Apollo [Fig. 12 p. I] has been only mention'd on account of the greatness of its proportion, I think in justice to so fine a performance; and also as it is not foreign to the point we have been upon, we may subjoin an Observation or two on its perfections.
