10A01, Emily, Visual Arts: Leonardo da Vinci as an artist

Leonardo da Vinci, a man often described as the archetype of the Renaissance man, was a polymath. Born in 1452, he has accomplished and invented so much that he greatly advanced the state of knowledge in the fields of anatomy, civil engineering, optics and hydrodynamics. Despite all this, however, he was and is renown primarily as a painter.

Renaissance Italy was centuries away from our culture of photographs and cinema, but Leonardo nevertheless sought a universal language in painting. With perspective and other realistic elements, Leonardo tried to create faithful renditions of life. In a culture previously dominated by highly figurative and downright strange religious paintings, Leonardo's desire to paint things realistically was bold and fresh. This call to objectivity became the standard for painters who followed in the 16th century.

Leonardo went beyond his teaching by making a scientific study of light and shadow in nature. It dawned on him that objects were not comprised of outlines, but were actually three-dimensional bodies defined by light and shadow. Known as chiaroscuro, this technique gave his paintings the soft, lifelike quality that made older paintings look cartoony and flat. He also saw that an object's detail and color changed as it receded in the distance. This technique, called sfumato, was originally developed by Flemish and Venetian painters, but of course Super-Genius Leonardo transformed it into a powerful tool for creating atmosphere and depth.

Ever the perfectionist, Leonardo turned to science in the quest to improve his artwork. His study of nature and anatomy emerged in his stunningly realistic paintings, and his dissections of the human body paved the way for remarkably accurate figures. He was the first artist to study the physical proportions of men, women and children and to use these studies to determine the "ideal" human figure. Unlike many of his contemporaries -- Michelangelo for example -- he didn't get carried away and paint ludicrously muscular bodies, which he referred to as "bags of nuts."

All in all, Leonardo believed that the artist must know not just the rules of perspective, but all the laws of nature. The eye, he believed, was the perfect instrument for learning these laws, and the artist the perfect person to illustrate them.
