Artist, engineer, inventor, anatomist, geologist cartographer and more: Leonardo da Vinci gave so much to the world. His fertile mind and scientific approach were centuries ahead of his time—and many of his works reputedly hold secrets in the form of codes and puzzles. Inspired by da Vinci's paintings, sketches, diagrams, and writings, this codex offers more than 150 enigmas to solve, from logic problems and riddles to code breaking, all beautifully illustrated in the style of the master.
