This masterly account of Leonardo da Vinci and his vision of the world is now widely recognized as the classic treatment of Leonardo's art, science, and thought, giving an unparalleled insight into the broadening and deepening of Leonardo's intellect and vision throughout his artistic career. Kemp, one of the world's leading authorities on Leonardo, takes us on a journey through the whole span of the great man's career, giving a fully integrated picture of his artistic, scientific, and technological achievements. Leonardo's early training in Florence provided a crucial foundation in the 'science of art', particularly perspective and anatomy. His period in the service of the Sforzas of Milan enlarged his outlook to embrace a wide range of natural sciences and mathematics, as he searched for scientific rules governing both man and the universe. It was these rules which provided the basis for his imaginative reconstruction of nature in great works such as the "Last Supper", the "Mona Lisa", and "St John", which reveal his increasingly complex vision of man in the context of nature.

And towards the end of his life, Leonardo became fascinated with the mathematics underlying the 'design of nature', behind which lay the ultimate force of the 'prime mover', as manifested with supreme power in his Deluge drawings. Covering all areas of Leonardo's achievement, generously illustrated, and now including a new introductory chapter setting Leonardo's work in its historical context, this fully updated new edition provides an unparalleled insight into the marvellous works of this central figure in western art.
