words, the various fables of the gods and heroes of antiquity; and the perfection of their art, which sometimes disarmed the gravity of the philosopher, always excited the applause and wonder of the people. The vast and magnificent theatres of Rome were filled by three thousand female dancers, and by three thousand singers, with the masters of the respective choruses. Such was the popular favor which they enjoyed, that, in a time of scarcity, when all strangers were banished from the city, the merit of contributing to the public pleasures exempted them from a law, which was strictly executed against the professors of the liberal arts. It is said, that the foolish curiosity of Elagabalus attempted to discover, from the quantity of spiders' webs, the number of the inhabitants of Rome. A more rational method of inquiry might not have been undeserving of the attention of the wisest princes, who could easily have resolved a question so important for the Roman government, and so interesting to succeeding ages. The births and deaths of the citizens were duly registered; and if any writer of antiquity had condescended to mention the annual amount, or the common average, we might now produce some satisfactory calculation, which would destroy the extravagant assertions of critics, and perhaps confirm the modest and probable conjectures of philosophers. The most diligent researches have collected only the following circumstances; which, slight and imperfect as they are, may tend, in some degree, to illustrate the question of the populousness of ancient Rome. I. When the capital of the empire was besieged by the Goths, the circuit of the walls was accurately measured, by Ammonius, the mathematician, who found it equal to twenty-one miles. It should not be forgotten that the form of the city was almost that of a circle; the geometrical figure which is known to contain the largest space within any given circumference. II. The architect Vitruvius, who flourished in the Augustan age, and whose evidence, on this occasion, has peculiar weight and authority, observes, that the innumerable habitations of the Roman people would have spread themselves far beyond the narrow limits of the city; and that the want of ground, which was probably contracted on every side by gardens and villas, suggested the common, though inconvenient, practice of raising the houses to a considerable height in the air. But the loftiness of these buildings, which often consisted of hasty work and insufficient materials, was the cause of frequent and fatal accidents; and it was repeatedly enacted by Augustus, as well as by Nero, that the height of private edifices within the walls of Rome, should not exceed the measure of seventy feet from the ground. III. Juvenal laments, as it should seem from his own experience, the hardships of the poorer citizens, to whom he addresses the salutary advice of emigrating, without delay, from the smoke
