At the beginning of the 1330s on of the most important travelogues describing the road through the then Mongolian Asia to China was written. Its author was Odoric of Pordenone (or of Friuli, of Udine, etc.), a Franciscan friar born near Pordenone. A large part of the travelogue is taken up by a story about four Franciscan missionaries and the alleged transfer of their bones by Odoric from the Indian city of Thana to one of the Franciscan settlements in southern China. This story occurs in almost all versions of Odoric´s travelogue, but it is missing in a few (except for a brief mention of the martyrdom of the four Franciscans). It seems that this passage, which incidentally, also considerably differs from the rest of the travelogue style, is a later addition, resulting from the influence of the emerging hagiographic tradition. My article presents the historical circumstances of the events that occured just prior to the arival of Odoric in Thana and their representation in the frescos in Udine. A constituent part of the article is a translation of a substantial part of this passage from Odoric´s travelogue, based on the Latin text of the unpublished manuscript XVII.E.2., held by the National Museum Library in Prague., Vladimír Liščák., and Obsahuje seznam literatury
