The heavier materials for building, as stone, lime, timber, were considered too bulky to be allowed a place in the square, and were deposited in the adjacent streets on the borders of the canals. It would be tedious to enumerate all the various articles, whether for luxury or daily use, which were collected from all quarters in this vast bazaar. I must not omit to mention, however, the display of provisions, one of the most attractive features of the _tianguez_; meats of all kinds, domestic poultry, game from the neighboring mountains, fish from the lakes and streams, fruits in all the delicious abundance of these temperate regions, green vegetables, and the unfailing maize. There was many a viand, too, ready dressed, which sent up its savory steams provoking the appetite of the idle passenger; pastry, bread of the Indian corn, cakes, and confectionery.[363] Along with these were to be seen cooling or stimulating beverages, the spicy foaming _chocolatl_, with its delicate aroma of vanilla, and the inebriating _pulque_, the fermented juice of the aloe. All these commodities, and every stall and portico, were set out, or rather smothered, with flowers, showing--on a much greater scale, indeed--a taste similar to that displayed in the markets of modern Mexico. Flowers seem to be the spontaneous growth of this luxuriant soil; which, instead of noxious weeds, as in other regions, is ever ready, without the aid of man, to cover up its nakedness with this rich and variegated livery of Nature.[364] I will spare the reader the repetition of all the particulars enumerated by the bewildered Spaniards, which are of some interest as evincing the various mechanical skill and the polished wants, resembling those of a refined community rather than of a nation of savages. It was the _material_ civilization, which belongs neither to the one nor the other. The Aztec had plainly reached that middle station, as far above the rude races of the New World as it was below the cultivated communities of the Old. As to the numbers assembled in the market, the estimates differ, as usual. The Spaniards often visited the place, and no one states the amount at less than forty thousand! Some carry it much higher.[365] Without relying too much on the arithmetic of the Conquerors, it is certain that on this occasion, which occurred every fifth day, the city swarmed with a motley crowd of strangers, not only from the vicinity, but from many leagues around; the causeways were thronged, and the lake was darkened by canoes filled with traders flocking to the great _tianguez_. It resembled, indeed, the periodical fairs in Europe, not as they exist now, but as they existed in the Middle Ages, when, from the difficulties of intercommunication, they served as the great central marts for commercial intercourse, exercising a most important and salutary influence on the community.
