The Polos returned from China with many riches. Kublai Khan had given them ivory, jade, jewels, porcelain, silk, and other treasures. When they arrived in Venice, the city was at war with Genoa, its long-time rival. In 1296, the Genoese captured and jailed Marco Polo. Historians do not know the details of his capture. In prison, Polo decided to write about his travels. Aided by his notes, he dictated the story to a popular writer, Rustichello of Pisa. Rustichello translated it into Old French, the literary language of Italy at the time. The book was completed in 1298.
In his book, called Description of the World, [excerpt] Polo told about Kublai Khan's prosperous, advanced empire. He described the Khan's postal system, which consisted of a vast network of courier stations. Riders on horseback relayed messages from one station to another.
Polo commented on many Chinese customs, such as the mining and use of coal as fuel. Coal had not yet been used in Europe. Polo called coal black stones. He also marveled at the Chinese use of paper money, which bore the seal of the emperor. At that time, Europeans traded with heavy coins made of copper, gold, or lead.
Printing had not yet been invented in Europe, and so scholars copied Polo's book by hand. Description of the World was widely read in Europe and may have influenced many explorers. It affected Christopher Columbus's estimate of the distance between Spain and Asia.
Description of the World stimulated European interest in Asia and helped bring to Europe such Chinese inventions as the compass, papermaking, and printing [and pasta.] Genoa and Venice made peace in 1299. Polo was freed and returned to trading in Venice.
