Miyamoto Musashi, swordmaster of the early Edo period (1603– 1868), dedicated his life to reach perfection throughout swordsmanship. He fought and won more than 60 life-or-death duels and ended his career invincible. He was interested in a variety of arts, as well as Zen meditation and Buddhism. He left for future generations not only his fight style but also an immense legacy of masterpieces on painting, sculpture, calligraphy, and poetry, as well as the most important Japanese treatise on strategy, The Book of Five Rings.
