Now to return to anatomy.

He gave up dissection because it turned his stomach so that he could neither eat nor drink with benefit.

It is very true that he did not give up until he was so learned and rich in such knowledge that he often had in his mind the wish to write, for the sake of sculptors and painters, a treatise on the movements of the human body, its aspect, and concerning the bones, with an ingenious theory of his own, devised after long practice.

He would have done it had he not mistrusted his powers, lest they should not suffice to treat with dignity and grace of such a subject, like one practised in the sciences and in rhetoric.

I know well that when he reads Alberto Duro he finds him very weak, seeing in his own mind how much more beautiful and useful his own conception would be.
