From the mountains on every side, rivulets descended, that filled all the valley with verdure and fertility, and formed a lake in the middle, inhabited by fish of every species, and frequented by every fowl whom nature has taught to dip the wing in water. This lake discharged its superfluities by a stream, which entered a dark cleft of the mountain on the northern side, and fell with dreadful noise from precipice to precipice till it was heard no more. The sides of the mountains were covered with trees; the banks of the brooks were diversified with flowers; every blast shook spices from the rocks, and every month dropped fruits upon the ground. All animals that bite the grass, or browse the shrub, whether wild or tame, wandered in this extensive circuit, secured from beasts of prey by the mountains which confined them. On one part were flocks and herds feeding in the pastures, on another all the beasts of chase frisking in the lawns; the sprightly kid was bounding on the rocks, the subtle monkey frolicking in the trees, and the solemn elephant reposing in the shade. All the diversities of the world were brought together; the blessings of nature were collected, and its evils extracted and excluded. The valley, wide and fruitful, supplied its inhabitants with the necessaries of life, and all delights and superfluities were added at the annual visit which the emperor paid his children, when the iron gate was opened to the sound of music, and, during eight days, every one that resided in the valley was required to propose whatever might contribute to make seclusion pleasant, to fill up the vacancies of attention, and lessen the tediousness of time. Every desire was immediately granted. All the artificers of pleasure were called to gladden the festivity; the musicians exerted the power of harmony, and the dancers showed their activity before the princes, in hope that they should pass their lives in this blissful captivity, to which those only were admitted whose performance was thought able to add novelty to luxury. Such was the appearance of security and delight which this retirement afforded, that they to whom it was new always desired that it might be perpetual; and as those on whom the iron gate had once closed were never suffered to return, the effect of longer experience could not be known. Thus every year produced new schemes of delight, and new competitors for imprisonment. The palace stood on an eminence, raised about thirty paces above the surface of the lake. It was divided into many squares or courts, built with greater or less magnificence, according to the rank of those for whom they were designed. The roofs were turned into arches of massy stone, joined by a cement that grew harder by time; and the building stood from century to century, deriding the solstitial rains and equinoctial hurricanes, without need of reparation.
