In the mind’s eye alone his figure view’d;
But Vinci saw him, and has both excell’d[i13].
To these must be added the following: A painting representing two horsemen engaged in fight, and struggling to tear a flag from each other: rage and fury are in this admirably expressed in the countenances of the two combatants; their air appears wild, and the drapery is thrown into an unusual though agreeable disorder. A Medusa’s head, and a picture of the Adoration of the Magi[i14]. In this last there are some fine heads, but both this and the Medusa’s head are said by Du Fresne to have been evidently unfinished.
The mind of Leonardo was however too active and capacious to be contented solely with the practical part of his art; nor could it submit to receive as principles, conclusions, though confirmed by experience, without first tracing them to their source, and investigating their causes, and the several circumstances on which they depended. For this purpose he determined to engage in a deep examination into the theory of his art; and the better to effect his intention, he resolved to call in to his aid the assistance of all such other branches of science as could in any degree promote this grand object.
Vasari has related[i15], that at a very early age he had, in the short time of a few months only that he applied to it, obtained a deep knowledge of arithmetic; and says, that in literature in general, he would have made great attainments, if he had not been too versatile to apply long to one subject. In music, he adds, he had made some progress; that he then determined to learn to play on the lyre; and that having an uncommonly fine voice, and an extraordinary promptitude of thought and expression, he became a celebrated improvisatore: but that his attention to these did not induce him to neglect painting and modelling in which last art he was so great a proficient, that in his youth he modelled in clay some heads of women laughing, and also some boys’ heads, which appeared to have come from the hand of a master. In architecture, he made many plans and designs for buildings, and, while he was yet young, proposed conveying the river Arno into the canal at Pisa[i16]. Of his skill in poetry the reader may judge from the following sonnet preserved by Lomazzo[i17], the only one now existing of his composition; and for the translation with which it is accompanied we are indebted to a lady.
SONNETTO MORALE.
Chi non può quel vuol, quel che può voglia,
Che quel che non si può folle è volere.
Adunque saggio è l’uomo da tenere,
Che da quel che non può suo voler toglia.
