Michelangelo wrote: “In my judgment that is the excellent and divine painting which is most like and best imitates any work of immortal God, whether a human figure, or a wild and strange animal, or a simple and easy fish, or a bird of the air, or any other creature.... To imitate perfectly each of these things in its species seems to me to be nothing else but to desire to imitate the work of immortal God. And yet that thing will be the most noble and perfect in the works of painting which in itself reproduced the thing which is most noble and of the greatest delicacy and knowledge.” Michelangelo thus reduces the philosophy of art to the simple problem of selection, and the faithful and truthful representation of the dominant, the graceful, the harmonious, and the beautiful in nature. His statement, which so simply, even quaintly, expresses the opinion of a great master whose works have commanded the homage of the world during nearly four centuries, is worthy of the most careful consideration. It reveals his reliance upon nature without confusion of thought or pretension of any kind. There are here no intricate definitions of art or complex theories concerning his method of creating his masterly representations of the best he found in nature--“the thing which is most noble!” The universality of this profound truth and of its independence of local conditions and circumstances is emphasized by the fact that another great master of another race, one whose technical methods and choice of subjects differed widely from those of Michelangelo, expressed the same reliance upon nature. [SN: _Albrecht Dürer_] Albrecht Dürer was a contemporary of Michelangelo, but he worked under widely different conditions. It is the great fundamental quality of truth so quaintly commended by Michelangelo that distinguishes the works of Albrecht Dürer. Albrecht Dürer wrote: “Life in Nature proves the truth of these things; therefore consider her diligently, guide thyself by her, and swerve not from Nature, thinking that thou canst find something better of thyself, for thou wilt be deceived. For Art standeth firmly fixed in Nature, and whoso can thence rend her forth, he only possesseth her.” [SN: _Leonardo da Vinci_] We find in Leonardo da Vinci’s notebook reference to this same principle. He recommends application to the study of the works of nature and advises the student to withdraw as far as possible from the companionship of others in order that he may more earnestly and effectively do this. His sage advice emphasizes the importance of study. “The eye, which is called the window of the soul, is the chief means whereby the understanding may most fully and abundantly appreciate the infinite works of nature.... All visible things derive their existence from nature, and from these same things is born painting.” [SN: _William Hogarth_]
