John Mandeville

Sir John Mandeville is the supposed author of The Travels of Sir John Mandeville, a travel memoir which first circulated between 1357 and 1371. The earliest-surviving text is in French. By aid of translations into many other languages, the work acquired extraordinary popularity. Despite the extremely unreliable and often fantastical nature of the travels it describes, it was used as a work of reference: Christopher Columbus, for example, was heavily influenced by both this work and Marco Polo's earlier Travels.
