Leonardo Da Vinci was left-handed. That's probably why he wrote backwards from right to left to avoid smudging ink on his hand as he made notes on his latest works and visionary discoveries. Words could only be read with the help of a mirror making it taxing for anyone but himself to quickly decode his handwriting. There are many theories exploring the reason why he kept using "mirror writing" in all his manuscripts. Some historians say that he was trying to make it more challenging for people to steal his ideas while others claim that it was a clever attempt to hide scientific findings from the intolerant Roman Catholic Church of the Renaissance. Whatever the logic behind this, the constant association with mirror writing and studies on the human body anatomy, made him one of the most enigmatic figures of his and then of our century. This biography investigates Leonardo and his different roles from anatomist to inventor, architect, painter, rumoured to be templar and scientific pioneer. Despite leaving several of his works incomplete, Leonardo managed to influence generations of artists and still today remains a highly regarded figure in both the artistic and scientific sector.

A singular fatality has ruled the destiny of nearly all the most famous of Leonardo da Vinci's works. Two of the three most important were never completed, obstacles having arisen during his life-time, which obliged him to leave them unfinished; namely the Sforza Monument and the Wall-painting of the Battle of Anghiari, while the third—the picture of the Last Supper at Milan—has suffered irremediable injury from decay and the repeated restorations to which it was recklessly subjected during the XVIIth and XVIIIth centuries. Nevertheless, no other picture of the Renaissance has become so wellknown and popular through copies of every description. Vasari says, and rightly, in his Life of Leonardo, "that he laboured much more by his word than in fact or by deed", and the biographer evidently had in his mind the numerous works in Manuscript which have been preserved to this day. To us, now, it seems almost inexplicable that these valuable and interesting original texts should have remained so long unpublished, and indeed forgotten. It is certain that during the XVIth and XVIIth centuries their exceptional value was highly appreciated. This is proved not merely by the prices which they commanded, but also by the exceptional interest which has been attached to the change of ownership of merely a few pages of Manuscript. That, notwithstanding this eagerness to possess the Manuscripts, their contents remained a mystery, can only be accounted for by the many and great difficulties attending the task of deciphering them. The handwriting is so peculiar that it requires considerable practice to read even a few detached phrases, much more to solve with any certainty the numerous difficulties of alternative readings, and to master the sense as a connected whole. Vasari observes with reference to Leonardos writing: "he wrote backwards, in rude characters, and with the left hand, so that any one who is not practised in reading them, cannot understand them". The aid of a mirror in reading reversed handwriting appears to me available only for a first experimental reading. Speaking from my own experience, the persistent use of it is too fatiguing and inconvenient to be practically advisable, considering the enormous mass of Manuscripts to be deciphered. And as, after all, Leonardo's handwriting runs backwards just as all Oriental character runs backwards—that is to say from right to left—the difficulty of reading direct from the writing is not insuperable. This obvious peculiarity in the writing is not, however, by any means the only obstacle in the way of mastering the text. Leonardo made use of an orthography peculiar to himself; he had a fashion of amalgamating several short words into one long one, or, again, he would quite arbitrarily divide a long word into two separate halves; added to this there is no punctuation whatever to regulate the division and construction of the sentences, nor are there any accents—and the reader may imagine that such difficulties were almost sufficient to make the task seem a desperate one to a beginner. It is therefore not surprising that the good intentions of some of Leonardo s most reverent admirers should have failed.

The #1 New York Times bestseller from Walter Isaacson brings Leonardo da Vinci to life in this exciting new biography that is “a study in creativity: how to define it, how to achieve it…Most important, it is a powerful story of an exhilarating mind and life” (The New Yorker). Based on thousands of pages from Leonardo da Vinci’s astonishing notebooks and new discoveries about his life and work, Walter Isaacson “deftly reveals an intimate Leonardo” (San Francisco Chronicle) in a narrative that connects his art to his science. He shows how Leonardo’s genius was based on skills we can improve in ourselves, such as passionate curiosity, careful observation, and an imagination so playful that it flirted with fantasy. He produced the two most famous paintings in history, The Last Supper and the Mona Lisa. With a passion that sometimes became obsessive, he pursued innovative studies of anatomy, fossils, birds, the heart, flying machines, botany, geology, and weaponry. He explored the math of optics, showed how light rays strike the cornea, and produced illusions of changing perspectives in The Last Supper. His ability to stand at the crossroads of the humanities and the sciences, made iconic by his drawing of Vitruvian Man, made him history’s most creative genius. In the “luminous” (Daily Beast) Leonardo da Vinci, Isaacson describes how Leonardo’s delight at combining diverse passions remains the ultimate recipe for creativity. So, too, does his ease at being a bit of a misfit: illegitimate, gay, vegetarian, left-handed, easily distracted, and at times heretical. His life should remind us of the importance to be imaginative and, like talented rebels in any era, to think different. Here, da Vinci “comes to life in all his remarkable brilliance and oddity in Walter Isaacson’s ambitious new biography…a vigorous, insightful portrait” (The Washington Post).

"[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.

Leonardo da Vinci had an insatiable desire to understand the world around him and the place of humanity in it, and he believed that the knowledge he sought could only be gained through direct experience. This book contains many extracts of his writings, revealing the complex workings of his mind.
