    Marco Polo on paper money (2)

    Who made it: Marco Polo, a Venetian merchant who served the Great Khan in China; the book was written down by Rustichello da Pisa, a writer of romances, from Polo's stories. When: the late 1200s. Where: about China under the Great Khan; written in Europe. For whom: readers in Europe. Why: to tell the marvels he had seen in the East. Excerpt (Marco Polo, Book II, chapter 24; English translation by Henry Yule, revised by Henri Cordier, 1903, p. 424): "…wheresoever a person may go throughout the Great Kaan's dominions [lands] he shall find these pieces of paper current [in use], and shall be able to transact all sales and purchases of goods by means of them just as well as if they were coins of pure gold. And all the while they are so light that ten bezants' worth does not weigh one golden bezant [a gold coin]." Source card "Ibn Battuta on paper money". Who made it: Ibn Battuta, a traveler and scholar from Tangier, Morocco. When: he traveled from 1325 to 1354 and dictated his account near the end of his life. Where: about China; told in North Africa. For whom: readers at home, who used gold and silver coins. Why: to record the wonders of the cities he visited. Excerpt (Ibn Battuta, Travels, chapter on China; English translation by H. A. R. Gibb, 1929, p. 283): "Their buying and selling is carried on exclusively by means of pieces of paper, each of the size of the palm of the hand, and stamped with the sultan's seal… When these notes become torn by handling, one takes them to an office corresponding to our mint, and receives their equivalent in new notes on delivering up the old ones." Source card "Paper money: what historians say today". Who made it: historians writing today. When: today. Where: China. For whom: readers today. Why: to sum up what research has found. Summary in our words, not a quotation: The first paper money, called jiaozi, appeared in the city of Chengdu in the 1000s CE, under the Song dynasty, before Marco Polo's time.

  2. Historians today say the first paper money appeared in the 1000s CE under the Song. Does that fit the travelers' accounts, Pia asks?

    • No: paper money began when Polo arrived in China
    • No: Ibn Battuta invented it
    • Yes: the Song were travelers
    • Yes: it was already in use when they came
  3. Where did paper money first appear, according to the cards, Tala asks?

    • Venice, say the three cards
    • Chengdu, says the historians' card
    • Tangier, says Ibn Battuta
    • Cambaluc, says Polo
  4. Polo writes from stories told to a romance writer; Ibn Battuta dictated his account years later. Which detail should Zee trust most?

    • Polo's numbers on bezants, from one source in the book
    • Ibn Battuta's note size, from one source
    • Each detail equally
    • That paper money was used, backed by all three

  6. A detail appears in just one traveler's account. What should Ari do with it?

    • Change it to match the other
    • Treat it as one source's report, to be checked
    • Throw it away, since one source alone must be false
