Good question! According to historians, Marco Polo himself wrotethat he spoke four languages, but did not state which theywere.We can assume that he spoke Mongolian because he was in serviceto the Mongol leader, the Kublai Khan, for 24 years, and was madegovernor of a province for 3 years. He also spent some time inPersia and Turkey, so most likely spoke those two languages, aswell. Being Italian, Marco also spoke Latin.
