Marco Polo did not personally write a book in the usual sense. Instead, while imprisoned in Genoa around 1298–1299, he dictated his travel stories to a romance writer named Rustichello da Pisa. This collaboration produced the famous travelogue known as "The Travels of Marco Polo," also called "The Book of the Marvels of the World," "Il Milione" (The Million), or "Description of the World." The book narrates his and his family's travels through Asia, including Polo's experiences at the court of Kublai Khan. The original manuscript does not survive, but many translations and versions exist, making it one of the most influential travel books of the medieval period.
