"[The Shadow Drawing] reorients our perspective, distills a life and brings it into focus—the very work of revision and refining that its subject loved best." —Parul Sehgal, The New York Times | Editors' Choice An entirely new account of Leonardo the artist and Leonardo the scientist, and why they were one and the same man Leonardo da Vinci has long been celebrated for his consummate genius. He was the painter who gave us the Mona Lisa and The Last Supper, and the inventor who anticipated the advent of airplanes, hot air balloons, and other technological marvels. But what was the connection between Leonardo the painter and Leonardo the scientist? Historians of Renaissance art have long supposed that Leonardo became increasingly interested in science as he grew older and turned his insatiable curiosity in new directions. They have argued that there are, in effect, two Leonardos—an artist and an inventor. In this pathbreaking new interpretation, the art historian Francesca Fiorani offers a different view. Taking a fresh look at Leonardo’s celebrated but challenging notebooks, as well as other sources, Fiorani argues that Leonardo became familiar with advanced thinking about human vision when he was still an apprentice in a Florence studio—and used his understanding of optical science to develop and perfect his painting techniques. For Leonardo, the task of the painter was to capture the interior life of a human subject, to paint the soul. And even at the outset of his career, he believed that mastering the scientific study of light, shadow, and the atmosphere was essential to doing so. Eventually, he set down these ideas in a book—A Treatise on Painting—that he considered his greatest achievement, though it would be disfigured, ignored, and lost in subsequent centuries. Ranging from the teeming streets of Florence to the most delicate brushstrokes on the surface of the Mona Lisa, The Shadow Drawing vividly reconstructs Leonardo’s life while teaching us to look anew at his greatest paintings. The result is both stirring biography and a bold reconsideration of how the Renaissance understood science and art—and of what was lost when that understanding was forgotten.

What's in a shadow? Menace, seduction, or salvation? Immaterial but profound, shadows lurk everywhere in literature and the visual arts, signifying everything from the treachery of appearances to the unfathomable power of God. From Plato to Picasso, from Rembrandt to Welles and Warhol, from Lord of the Rings to the latest video game, shadows act as central players in the drama of Western culture. Yet because they work silently, artistic shadows often slip unnoticed past audiences and critics. Conceived as an accessible introduction to this elusive phenomenon, Grasping Shadows is the first book that offers a general theory of how all shadows function in texts and visual media. Arguing that shadow images take shape within a common cultural field where visual and verbal meanings overlap, William Sharpe ranges widely among classic and modern works, revealing the key motifs that link apparently disparate works such as those by Fra Angelico and James Joyce, Clementina Hawarden and Kara Walker, Charles Dickens and Kumi Yamashita. Showing how real-world shadows have shaped the meanings of shadow imagery, Grasping Shadows guides the reader through the techniques used by writers and artists to represent shadows from the Renaissance onward. The last chapter traces how shadows impact the art of the modern city, from Renoir and Zola to film noir and projection systems that capture the shadows of passers-by on streets around the globe. Extending his analysis to contemporary street art, popular songs, billboards, and shadow-theatre, Sharpe demonstrates a practical way to grasp the "dark side" that looms all around us.

What exactly is a shadow? Is it light tracing an object or the shape a body throws when it comes between a light source and a surface? Is it a metaphor for the intimate, darker side of a person's nature-as Carl Jung postulated-and the unconscious side of one's self, where daemons and secrets are kept hidden or repressed? Is it an allegorical place between darkness and light, death and living? Or is it a state of illusion, like Plato's cave? Is it a verb that means to follow or accompany, or even to spy on? Shadows, a new collaborative series by Alexandra Grant and Keanu Reeves, explores the real and symbolic nature of the shadow as image and figure of speech. Grant's photographs capture Reeves's shadow at times as a silhouette and at others as traces of light as he and the camera move together. In transforming the images into color and reversing light for dark, Grant has made the shadows themselves the source of light. Reeves's texts, written in tandem with the creation of the images, give voice to the multiple manifestations of the shadow: as a projected figure, a place of concealed emotion and an invocation to shadow play.
