If a man 2 braccia high is too small, one of four is too tall, the medium being what is admirable. Between 2 and 4 comes 3; therefore take a man of 3 braccia in height and measure him by the rule I will give you. If you tell me that I may be mistaken, and judge a man to be well proportioned who does not conform to this division, I answer that you must look at many men of 3 braccia, and out of the larger number who are alike in their limbs choose one of those who are most graceful and take your measurements. The length of the hand is 1/3 of a braccio [8 inches] and this is found 9 times in man. And the face [Footnote 7: The account here given of the _braccio_ is of importance in understanding some of the succeeding chapters. _Testa_ must here be understood to mean the face. The statements in this section are illustrated in part on Pl. XI.] is the same, and from the pit of the throat to the shoulder, and from the shoulder to the nipple, and from one nipple to the other, and from each nipple to the pit of the throat. Proportions of the head and face (310-318). 310. The space between the parting of the lips [the mouth] and the base of the nose is one-seventh of the face. The space from the mouth to the bottom of the chin _c d_ is the fourth part of the face and equal to the width of the mouth. The space from the chin to the base of the nose _e f_ is the third part of the face and equal to the length of the nose and to the forehead. The distance from the middle of the nose to the bottom of the chin _g h_, is half the length of the face. The distance from the top of the nose, where the eyebrows begin, to the bottom of the chin, _i k_, is two thirds of the face. The space from the parting of the lips to the top of the chin _l m_, that is where the chin ends and passes into the lower lip of the mouth, is the third of the distance from the parting of the lips to the bottom of the chin and is the twelfth part of the face. From the top to the bottom of the chin _m n_ is the sixth part of the face and is the fifty fourth part of a man's height. From the farthest projection of the chin to the throat _o p_ is equal to the space between the mouth and the bottom of the chin, and a fourth of the face. The distance from the top of the throat to the pit of the throat below _q r_ is half the length of the face and the eighteenth part of a man's height. From the chin to the back of the neck _s t_, is the same distance as between the mouth and the roots of the hair, that is three quarters of the head. From the chin to the jaw bone _v x_ is half the head and equal to the thickness of the neck in profile. The thickness of the head from the brow to the nape is once and 3/4 that of the neck.
