Odoric of Pordenone (c. 1275/85-1331), a Franciscan friar and one of the chief travelers to Asia during the later Middle Ages, traveled between 1314/131899 ab 1330 to the "eastern parts of the world" (orientalium partium), and on the return journey he may have visited Tibet (or some of its outlying areas). After his return in 1330, he dictated an account of his travels, which soon became a best-seller. Since it included many descriptions and facts not mentioned in Marco Polo´s "Il Milione", the text became an important source both for the fictious account of "John Mandeville" and the famous Catalan Atlas of 1375. There are many mysteries about Odoric and his travels, including some doubt as to whether he was actually in China. In addition, very little is known about his missionary activities in China and about his journey back to Europe. One of the everlasting questions is: Was he really in Tibet, as mentioned in his account?
