It is ill to praise, and worse to reprimand in matters that you do not understand. - Leonardo da Vinci

Chi poco pensa, molto erra.

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.

Noi tutti siamo esiliati
entro lo cornici di uno strano quadro.
Chi sa questo, viva da grande,
Gli altri sono insetti.
