Marco Polo
Japan was one of the last countries to be discovered by Europeans. In his travelogue "Il Milione" (1298), Marco Polo reports on a country east of China. The Chinese call it Jipenkuo, the land where the sun rises. He himself calls it Cipango. It twice repelled Kublai Khan's attempts to conquer it. Cipango is described as a very large island 1500 miles east of the Chinese coast. Beautiful, well-behaved, pagan, white people live there. The adjective "white" is to be understood here in the sense of "civilized", civilized like the Europeans.
At the time of Marco Polo, the known world consisted of Europe, Africa (not yet circumnavigated; the circumnavigation, reported by Herodotus around 450 BC, had been forgotten) and part of Asia. The classification of peoples was based on the three sons of Noah: Japheth, from whom the Caucasians and Europeans descended; Ham, the progenitor of the Africans; and Shem, the progenitor of the Semites (Asians).
Marco Polo's travelogue was the only work that reported on Japan until the 16th century.
