+<blockquote><poem>
 Besides this, in order to investigate the subtleties of art, he set himself one day to make his own portrait, looking at himself in a convex barber's mirror. And in doing this, perceiving the bizarre effects produced by the roundness of the mirror, which twists the beams of a ceiling into strange curves, and makes the doors and other parts of buildings recede in an extraordinary manner, the idea came to him to amuse himself by counterfeiting everything. Thereupon he had a ball of wood made by a turner, and, dividing it in half so as to make it the same in size and shape as the mirror, set to work to counterfeit on it with supreme art all that he saw in the glass, and particularly his own self, which he did with such lifelike reality as could not be imagined or believed.
