Leonardo da Vinci (1452-1519) is widely considered to have possessed one of the greatest minds the world has ever known. Artist, draftsman, inventor, and philosopher, his contributions to modern society are profound and wide reaching. Throughout his life, Leonardo filled many notebooks with elegant studies on topics ranging from the nature of water, light and shade, philosophy, botany, astronomy, architecture, and the human figure. This lovely week-at-a-glance desk calendar excerpts the most extraordinary of Leonardo's musings and illustrates them with his glorious artwork, providing stimulation and inspiration for each week of the year.
