The passage of the Changai Mountains was a terrible undertaking; the cold was intense and the weather stormy, and the khan, with his usual bland eclecticism, begged Rubruquis to “pray to God in his own fashion” for milder weather, chiefly for the sake of the cattle. On Palm Sunday the envoy blessed the willow-boughs he saw on his way, though he says there were no buds on them yet; but they were near the city now, and the weather had become more promising. Rubruquis had his eyes wide open as he came to the first organized city of the Tartars, as Marco Polo affirms this to have been. It had scarcely been built twenty years when our monk visited it, and owed its origin to the son and successor of Jengis-Khan. “There were two grand streets in it,” says Rubruquis, “one of the Saracens, where the fairs are kept (held), and many merchants resort thither, and one other street of the Cathayans (Chinese), who are all artificers.” Many of the latter were captives, or at least subjects, of the khan; for the Tartars had already conquered the greater part of Northern China. The khan lived in a castle or palace outside the earthen rampart. In Karakorum, again, the monk found many Christians, Armenian, Georgian, Hungarian, and even of Western European origin. Among others he mentions an Englishman--whom he calls Basilicus, and who had been born in Hungary--and a few Germans. But the most important personage of foreign birth was a French goldsmith, William Bouchier, whose wife was a Hungarian, but of Mahometan parentage. This Benvenuto Cellini of the East was rich and liberal, an excellent interpreter, thoroughly at home in the Tartar dialects, a skilful artist, and in high favor at court. He had just finished a masterpiece of mechanism and beauty which Rubruquis thus minutely describes: “In the khan’s palace, because it was unseemly to carry about bottles of milk and other drinks there, Master William made him a great silver tree, at the root whereof were four silver lions, having each one pipe, through which flowed pure cow’s milk; and four other pipes were conveyed within the body of the tree unto the top thereof, and the tops spread back again downwards, and upon every one of them was a golden serpent, whose tails twined about the body of the tree. And one of these pipes ran with wine, another with cara-cosmos, another with _ball_--a drink made of honey--and another with a drink made of rice. Between the pipes, at the top of the tree, he made an angel holding a trumpet, and under the tree a hollow vault, wherein a man might be hid; and a pipe ascended from this vault through the tree to the angel. He first made bellows, but they gave not wind enough. Without the palace walls there was a chamber wherein the several drinks were brought; and there were servants there ready to pour them out when they heard the angel sounding his trumpet. And the boughs of the tree were of silver, and the leaves and the fruit. When, therefore, they want drink,
