Everywhere the Conquerors beheld the evidence of a crowded and thriving population, exceeding all they had yet seen. The temples and principal buildings of the cities were covered with a hard white stucco, which glistened like enamel in the level beams of the morning. The margin of the great basin was more thickly gemmed than that of Chalco with towns and hamlets.[266] The water was darkened by swarms of canoes filled with Indians,[267] who clambered up the sides of the causeway and gazed with curious astonishment on the strangers. And here, also, they beheld those fairy islands of flowers, overshadowed occasionally by trees of considerable size, rising and falling with the gentle undulation of the billows. At the distance of half a league from the capital, they encountered a solid work or curtain of stone, which traversed the dike. It was twelve feet high, was strengthened by towers at the extremities, and in the centre was a battlemented gateway, which opened a passage to the troops. It was called the Fort of Xoloc, and became memorable in after-times as the position occupied by Cortés in the famous siege of Mexico.
Here they were met by several hundred Aztec chiefs, who came out to announce the approach of Montezuma and to welcome the Spaniards to his capital. They were dressed in the fanciful gala costume of the country, with the _maxtlatl_, or cotton sash, around their loins, and a broad mantle of the same material, or of the brilliant feather-embroidery, flowing gracefully down their shoulders. On their necks and arms they displayed collars and bracelets of turquoise mosaic, with which delicate plumage was furiously mingled,[268] while their ears, under-lips, and occasionally their noses, were garnished with pendants formed of precious stones, or crescents of fine gold. As each cacique made the usual formal salutation of the country separately to the general, the tedious ceremony delayed the march more than an hour. After this, the army experienced no further interruption till it reached a bridge near the gates of the city. It was built of wood, since replaced by one of stone, and was thrown across an opening of the dike, which furnished an outlet to the waters when agitated by the winds or swollen by a sudden influx in the rainy season. It was a drawbridge; and the Spaniards, as they crossed it, felt how truly they were committing themselves to the mercy of Montezuma, who, by thus cutting off their communications with the country, might hold them prisoners in his capital.[269]
