emeralds, rubies and sapphires, as could never have been imagined, "which had all been stitched up in those dresses in so artful a fashion that nobody could have suspected the fact." In such wise had they brought home from Cathay their ample earnings; and when it became known about Venice that the three long-lost citizens had come back, "straightway the whole city, gentle and simple, flocked to the house to embrace them, and to make much of them, with every conceivable demonstration of affection and respect."[331] [Footnote 330: Pauthier's _Marco Polo_, p. 361; Yule's _Marco Polo_, p. li.] [Footnote 331: Ramusio, _apud_ Yule's _Marco Polo_, vol. i. p. xxxvii.] [Sidenote: Marco Polo's book written in prison at Genoa, 1299.] Three years afterward, in 1298, Marco commanded a galley in the great naval battle with the Genoese near Curzola. The Venetians were totally defeated, and Marco was one of the 7,000 prisoners taken to Genoa, where he was kept in durance for about a year. One of his companions in captivity was a certain Rusticiano, of Pisa, who was glad to listen to his descriptions of Asia, and to act as his amanuensis. French was then, at the close of the Crusades, a language as generally understood throughout Europe as later, in the age of Louis XIV.; and Marco's narrative was duly taken down by the worthy Rusticiano in rather lame and shaky French. In the summer of 1299 Marco was set free and returned to Venice, where he seems to have led a quiet life until his death in 1324. [Sidenote: Its great contributions to geographical knowledge.] "The Book of Ser Marco Polo concerning the Kingdoms and Marvels of the East" is one of the most famous and important books of the Middle Ages. It contributed more new facts toward a knowledge of the earth's surface than any book that had ever been written before. Its author was "the first traveller to trace a route across the whole longitude of Asia;" the first to describe China in its vastness, with its immense cities, its manufactures and wealth, and to tell, whether from personal experience or direct hearsay, of Thibet and Burmah, of Siam and Cochin China, of the Indian archipelago, with its islands of spices, of Java and Sumatra, and of the savages of Andaman. He knew of Japan and the woful defeat of the Mongols there, when they tried to invade the island kingdom in 1281. He gave a description of Hindustan far more complete and characteristic than had ever before been published. From Arab sailors, accustomed to the Indian ocean, he learned something about Zanzibar and Madagascar and the semi-Christian kingdom of Abyssinia. To the northward from Persia he described the country of the Golden Horde, whose khans were then holding Russia in subjection; and he had gathered some accurate information concerning Siberia as far as the country of the Samoyeds, with their dog-sledges and polar bears.[332] [Footnote 332: Yule's _Marco Polo_, vol. i. p. cxxxi.]
