It is clear that Leonardo, through his comprehension of art, began many things and never finished one of them, since it seemed to him that the hand was not able to attain to the perfection of art in carrying out the things which he imagined; for the reason that he conceived in idea difficulties so subtle and so marvellous, that they could never be expressed by the hands, be they ever so excellent. And so many were his caprices, that, philosophizing of natural things, he set himself to seek out the properties of herbs, going on even to observe the motions of the heavens, the path of the moon, and the courses of the sun. He was placed, then, as has been said, in his boyhood, at the instance of Ser Piero, to learn art with Andrea del Verrocchio, who was making a panel-picture of S. John baptizing Christ, when Leonardo painted an angel who was holding some garments; and although he was but a lad, Leonardo executed it in such a manner that his angel was much better than the figures of Andrea; which was the reason that Andrea would never again touch colour, in disdain that a child should know more than he. [Illustration: ANDREA VERROCCHIO: THE BAPTISM IN JORDAN (_Florence: Accademia, 71. Panel_)] He was commissioned to make a cartoon for a door-hanging that was to be executed in Flanders, woven in gold and silk, to be sent to the King of Portugal, of Adam and Eve sinning in the Earthly Paradise; wherein Leonardo drew with the brush in chiaroscuro, with the lights in lead-white, a meadow of infinite kinds of herbage, with some animals, of which, in truth, it may be said that for diligence and truth to nature divine wit could not make it so perfect. In it is the fig-tree, together with the foreshortening of the leaves and the varying aspects of the branches, wrought with such lovingness that the brain reels at the mere thought how a man could have such patience. There is also a palm-tree which has the radiating crown of the palm, executed with such great and marvellous art that nothing save the patience and intellect of Leonardo could avail to do it. This work was carried no farther; wherefore the cartoon is now at Florence, in the blessed house of the Magnificent Ottaviano de' Medici, presented to him not long ago by the uncle of Leonardo.
