In one quarter was an aviary, filled with numerous kinds of birds, remarkable in this region both for brilliancy of plumage and of song. The gardens were intersected by a canal communicating with the lake of Tezcuco, and of sufficient size for barges to enter from the latter. But the most elaborate piece of work was a huge reservoir of stone, filled to a considerable height with water well supplied with different sorts of fish. The basin was sixteen hundred paces in circumference, and was surrounded by a walk, made also of stone, wide enough for four persons to go abreast. The sides were curiously sculptured, and a flight of steps led to the water below, which fed the aqueducts above noticed, or, collected into fountains, diffused a perpetual moisture.
Such are the accounts transmitted of these celebrated gardens, at a period when similar horticultural establishments were unknown in Europe;29 and we might well doubt their existence in this semi-civilized land, were it not a matter of such notoriety at the time and so explicitly attested by the invaders. But a generation had scarcely passed after the Conquest, before a sad change came over these scenes so beautiful. The town itself was deserted, and the shore of the lake was strewed with the wreck of buildings which once were its ornament and its glory. The garden shared the fate of the city. The retreating waters withdrew the means of nourishment, converting the flourishing plains into a foul and unsightly morass, the haunt of loathsome reptiles; and the water-fowl built her nest in what had once been the palaces of princes!30
