Marco Polo was an explorer during the Middle Ages.
Cut off from his medieval sources in Europe due to World War I, Professor Henry Jones traveled to China in 1914 hoping to find mentions of Marco Polo in imperial records. In 1933, Tzen Khan met Indiana Jones and suggested that the archaeologist could be a reincarnation of Polo.
