Throughout history, some books have changed the world. They have transformed the way we see ourselves - and each other. They have inspired debate, dissent, war and revolution. They have enlightened, outraged, provoked and comforted. They have enriched lives - and destroyed them. Now Penguin brings you the works of the great thinkers, pioneers, radicals and visionaries whose ideas shook civilization and helped make us who we are. A profound influence on medieval Europe´s view of the wider world, this thirteenth-century account of a Venetian merchant´s amazing experiences in the court of the great Mongol leader, Kubilai Khan, remains one of the most fascinating tales of exploration ever written.
