The game was created after this was documented in The Travels of Marco Polo - Volume 1: " And I was swept down by the mighty torrent. I was snagged by a fallen tree a ways downstream. My father and uncle could not see me, as the morning fog had not yet lifted, and I could not see my hand when directly in front of my face. Then I heard a faint whistle in the wind, "Marco! Marco!" I heard my father crying. I responded with the only thing I could think of, "Polo!" I shouted. He then walked the bank of the river and found the tree I had been snagged on, climbing out to save me." - Marco Polo, from, The travels of Marco Polo.
