“The Vitruvian proportions of a man’s body first standing inscribed in a square and then with feet and arms
outspread inscribed in a circle provides an excellent early example of the way in which his studies of
proportion fuse artistic and scientific objectives. It is Leonardo, not Vitruvius, who points out that ‘If you
open the legs so as to reduce the stature by one-fourteenth and open and raise your arms so that your middle
fingers touch the line through the top of the head, know that the centre of the extremities of the outspread
limbs will be the umbilicus, and the space between the legs will make and equilateral triangle’ (Accademia,
Venice). Here he provides one of his simplest illustrations of a shifting ‘centre of magnitude’ without a
corresponding change of ‘centre of normal gravity’. This remains passing through the central line from the pit
of the throat through the umbilicus and pubis between the legs. Leonardo repeatedly distinguishes these two
different ‘centres’ of a body, i.e., the centers of ‘magnitude’ and ‘gravity (Keele 252).”
