Marco Polo was a Venetian merchant traveller whose travels are recorded in Livres des merveilles du monde (Book of the Marvels of the World, also known as The Travels of Marco Polo, c. 1300), a book that introduced Europeans to Central Asia and China. By the way, Polo's travels were written down by Rustichello of Pisa in prison, where they were chambered together. Rustichello became Polo's ghostwriter. The famous book had been completed by the time of Polo and Rustichello's release in 1299.
