The Kaan bade them with all his heart have such mangonels made as speedily as possible. Now Messer Nicolo and his brother and his son immediately caused timber to be brought, as much as they desired, and fit for the work in hand. And they had two men among their followers, a German and a Nestorian Christian, who were masters of that business, and these they directed to construct two or three mangonels capable of casting stones of 300 lbs. weight. Accordingly they made three fine mangonels, each of which cast stones of 300 lbs. weight and more.{2} And when they were complete and ready for use, the Emperor and the others were greatly pleased to see them, and caused several stones to be shot in their presence; whereat they marvelled greatly and greatly praised the work. And the Kaan ordered that the engines should be carried to his army which was at the leaguer of Saianfu.{3} And when the engines were got to the camp they were forthwith set up, to the great admiration of the Tartars. And what shall I tell you? When the engines were set up and put in gear, a stone was shot from each of them into the town. These took effect among the buildings, crashing and smashing through everything with huge din and commotion. And when the townspeople witnessed this new and strange visitation they were so astonished and dismayed that they wist not what to do or say. They took counsel together, but no counsel could be suggested how to escape from these engines, for the thing seemed to them to be done by sorcery. They declared that they were all dead men if they yielded not, so they determined to surrender on such conditions as they could get.{4} Wherefore they straightway sent word to the commander of the army that they were ready to surrender on the same terms as the other cities of the province had done, and to become the subjects of the Great Kaan; and to this the captain of the host consented. So the men of the city surrendered, and were received to terms; and this all came about through the exertions of Messer Nicolo, and Messer Maffeo, and Messer Marco; and it was no small matter. For this city and province is one of the best that the Great Kaan possesses, and brings him in great revenues.{5} NOTE 1.—Pauthier’s MS. C. here says: “When the Great Kaan, and the Barons about him, and the messengers from the camp ... heard this, they all marvelled greatly; for I tell you that in all those parts they know nothing of mangonels or trebuchets; and they were so far from being accustomed to employ them in their wars that they had never even seen them, nor knew what they were.” The MS. in question has in this narrative several statements peculiar to itself,[1] as indeed it has in various other passages of the book; and these often look very like the result of revision by Polo himself. Yet I have not introduced the words just quoted into our text, because they are, as we shall see presently, notoriously contrary to fact.
