".in the first place make yourself a master of perspective, then acquire perfect knowledge of the proportions of men and other animals, and also, study good architecture.'' Leonardo da Vinci's desire for accuracy and realism in his work drove him to take an almost forensic approach to recording the world around him, and to produce an enormous number of paintings, drawings, plans and diagrams. Selected from the entire range of Leonardo's finest drawings, this book presents a comprehensive and inspiring collection that is testament to Leonardo's accurate eye and unfailing hand. Once you have studied these images you will begin to understand why Leonardo believed the eye was the perfect instrument for absorbing all the laws of nature, and that the artist was the perfect instrument for their expression.
