The limbs should be adapted to the body with grace and with
reference to the effect that you wish the figure to produce. And if
you wish to produce a figure that shall of itself look light and
graceful you must make the limbs elegant and extended, and without
too much display of the muscles; and those few that are needed for
your purpose you must indicate softly, that is, not very prominent
and without strong shadows; the limbs, and particularly the arms
easy; that is, none of the limbs should be in a straight line with
the adjoining parts. And if the hips, which are the pole of a man,
are by reason of his position, placed so, that the right is higher
than the left, make the point of the higher shoulder in a
perpendicular line above the highest prominence of the hip, and let
this right shoulder be lower than the left. Let the pit of the
throat always be over the centre of the joint of the foot on which
the man is leaning. The leg which is free should have the knee lower
than the other, and near the other leg. The positions of the head
and arms are endless and I shall therefore not enlarge on any rules
for them. Still, let them be easy and pleasing, with various turns
and twists, and the joints gracefully bent, that they may not look
like pieces of wood.
Of appropriate gestures (593-600).

A picture or representation of human figures, ought to be done in
such a way as that the spectator may easily recognise, by means of
their attitudes, the purpose in their minds. Thus, if you have to
represent a man of noble character in the act of speaking, let his
gestures be such as naturally accompany good words; and, in the same
way, if you wish to depict a man of a brutal nature, give him fierce
movements; as with his arms flung out towards the listener, and his
head and breast thrust forward beyond his feet, as if following the
speaker's hands. Thus it is with a deaf and dumb person who, when he
sees two men in conversation--although he is deprived of
hearing--can nevertheless understand, from the attitudes and
gestures of the speakers, the nature of their discussion. I once saw
in Florence a man who had become deaf who, when you spoke very loud
did not understand you, but if you spoke gently and without making
any sound, understood merely from the movement of the lips. Now
perhaps you will say that the lips of a man who speaks loudly do not
move like those of one speaking softly, and that if they were to
move them alike they would be alike understood. As to this argument,
I leave the decision to experiment; make a man speak to you gently
and note [the motion of] his lips.
