To return, however, to the description of the palace. The space between the first and second walls was bare and level, and appropriated to the exercising of the troops. But having passed the second wall, you discovered an immense park, resembling the paradises of the ancient Persian kings, stretching away on all sides into green lawns, dotted and broken into long sunny vistas or embowered shades by numerous groves of trees, between the rich and various foliage of which the glittering pinnacles and snow-white battlements of the palace walls appeared at intervals. The palace itself was a mile in length, but, not being of corresponding height, had rather the appearance of a vast terrace or range of buildings than of one structure. Its interior was divided into numerous apartments, some of which were of prodigious dimensions and splendidly ornamented; the walls being covered with figures of men, birds, and animals in exquisite relief and richly gilt. A labyrinth of carving, gilding, and the most brilliant colours, red, green, and blue, supplied the place of a ceiling; and the united effect of the whole oppressed the soul with a sense of painful splendour. On the north of this poetical abode, which rivalled in vastness and magnificence the Olympic domes of Homer, stood an artificial hill, a mile in circumference and of corresponding height, which was skilfully planted with evergreen trees, which the Great Khan had caused to be brought from remote places, with all their roots, on the backs of elephants. At the foot of this hill were two beautiful lakes imbosomed in trees, and filled with a multitude of delicate fish. That portion of the imperial city which had been erected by Kublai Khan was square, like his palace. It was less extensive, however, than the royal grounds, being only twenty-four miles in circumference. The streets were all straight, and six miles in length, and the houses were erected on each side, with courts and gardens, like palaces. At a certain hour of the night, a bell, like the curfew of the Normans, was sounded in the city, after which it was not lawful for any person to go out of doors unless upon the most urgent business; for example, to procure assistance for a woman in labour; in which case, however, they were compelled to carry torches before them, from which we may infer that the streets were not lighted with lamps. Twelve extensive suburbs, inhabited by foreign merchants and by tradespeople, and more populous than the city itself, lay without the walls.
