What is the name of a travelogue written down from stories told by Italian explorer Marco Polo?

Book of the Marvels of the World, in English commonly called The Travels of Marco Polo, is a 13th-century travelogue written down by Rustichello da Pisa from stories told by Italian explorer Marco Polo, describing Polo's travels through Asia between 1271 and 1295, and his experiences at the court of Kublai Khan.

The book was written by romance writer Rustichello da Pisa, who worked from accounts which he had heard from Marco Polo when they were imprisoned together in Genoa. Rustichello wrote it in langues d'Oil, a lingua franca of crusaders and western merchants in the Orient. It was originally known as Livre des Merveilles du Monde or Devisement du Monde ("Description of the World").

From the beginning, there has been incredulity over Polo's sometimes fabulous stories, as well as a scholarly debate in recent times. Some have questioned whether Marco had actually travelled to China or was just repeating stories that he had heard from other travellers.

Economic historian Mark Elvin concludes that recent work "demonstrates by specific example the ultimately overwhelming probability of the broad authenticity" of Polo's account, and that the book is, "in essence, authentic, and, when used with care, in broad terms to be trusted as a serious though obviously not always final, witness."
