Book excerpt: From a leading art instructor at the Pennsylvania Academy of Fine Arts in Philadelphia, a complete survey of drawing as an art form covering its history, materials, and key techniques, alongside step-by-step demonstrations. Foundations of Drawing is a comprehensive and authoritative overview of the history, aesthetics, methods, and materials of the drawing medium. Throughout, clearly defined demonstrations provide easy access to the practice of drawing as well as the history and development of core drawing techniques. Richly illustrated, the book contains reproductions of the finest master drawings from the fifteenth century to the present. Unlike other drawing instruction books that focus on step-by-step lessons exclusively, Foundations of Drawing provides readers with the context and background to help understand just why these materials and methods are so vital for successful drawing.
