3998144A Treatise on Painting — Of being universalJohn Francis RigaudLeonardo da Vinci

Chap. XXVIII.Of being universal.

It is an easy matter for a man who is well versed in the principles of his art, to become universal in the practice of it, since all animals have a similarity of members, that is, muscles, tendons, bones, &c. These only vary in length or thickness, as will be demonstrated in the Anatomy[1]. As for aquatic animals, of which there is great variety, I shall not persuade the painter to take them as a rule, having no connexion with our purpose.

  1. An intended Treatise, as it seems, on Anatomy, which however never was published; but there are several chapters in the present work on the subject of Anatomy, most of which will be found under the present head of Anatomy; and of such as could not be placed there, because they also related to some other branch, the following is a list by which they may be found: Chapters vi. vii. x. xi. xxxiv. xxxv. xxxvi. xxxvii. xxxviii. xxxix. xl. xli. xlii. xliii. xliv. xlv. xlvi. xlviii. xlix. l. li. lii. cxxix.
