Scientist, painter, mechanical engineer, sculptor, thinker, city planner, storyteller, musician, architect--Leonardo da Vinci was one of the great universal geniuses of Western civilization. His voluminous notebooks, the great storehouse of his theories and discoveries, are presented here in 1566 extracts in both Italian and English, as are 186 plates of manuscript pages and many other drawings reproduced in facsimile size.The first volume, which contains all of Leonardo's writings on aspects of painting, includes discussions of such basic scientific areas as the structure of the eye and vision, perspective, the science of light and shade, the perspective of disappearance, theory of color, perspective of color, proportions and movements of the human figure, botany for painters, and the elements of landscape painting. A section on the practice of painting includes moral precepts for painters and writings on composition, materials, and the philosophy of art. A selection of philosophical maxims, morals, polemics, fables, jests, studies in the lives and habits of animals, tales, and prophecies display Leonardo's abilities as a writer and scholar.
