[395] On the man who rests upon both his feet and gives more weight of himself to one than to the other.
When, through standing a long time on his feet, a man has tired the leg on which he rests, he sends part of the weight onto the other leg; but such a way of standing is to be used only by decrepit age, or infancy, or indeed by one who is tired, because it shows weariness or little strength of limbs; and therefore one always sees a young man, who is healthy and vigorous, resting upon one of his legs, and if he gives some weight to the other leg, he uses it when he wishes to give the necessary beginning to his movement, without which every motion is denied, because motion is generated from inequality.

[396] On the postures of figures.
Figures that stand at rest should always vary the limbs, that is, if one arm goes forward, that the other stay still or go back; and if the figure rests upon one leg, that the shoulder which is above that leg be lower than the other; and this is caused by men of good sense, who always attend by nature to balancing the man over his feet, so that he does not fall from his feet; because, resting upon one foot, the opposite leg does not support the man, being bent, which in itself is as if it were dead; whence necessity makes it that the weight which is from the legs upward sends the centre of its gravity over the joint of the leg that supports it.
