Compiled in 1505, the Codex on Flight by Leonardo da Vinci presents the most important study on flight completed before the 19th century. It features both theoretical and experimental analyses derived from observing birds in flight. But there’s much more. All the drawings and texts are aimed at accomplishing the great dream: to build a machine for human flight. Not only does the Codex explain how to make it, but also how to fly it. For the first time ever, this book describes a flying machine designed by Leonardo that has never been revealed before: the “Great Kite”. The contents are narrated with 3D images and explanations of all texts. This book, which is arguably the definitive source for understanding the Codex on Flight, also contains: a complete facsimile at the highest-quality resolution ever published; semi-diplomatic and critical transcriptions of all the texts; and the history of flight before and after Leonardo.
