The History of the Decline and Fall of the Roman Empire - Edward Gibbon [952]
[Footnote 63: In the time of Quintilian and Pliny, a tragic poet was reduced to the imperfect method of hiring a great room, and reading his play to the company, whom he invited for that purpose. (See Dialog. de Oratoribus, c. 9, 11, and Plin. Epistol. vii. 17.)]
[Footnote 64: See the dialogue of Lucian, entitled the Saltatione, tom. ii. p. 265 - 317, edit. Reitz. The pantomimes obtained the honorable name; and it was required, that they should be conversant with almost every art and science. Burette (in the Memoires de l'Academie des Inscriptions, tom. i. p. 127, &c.) has given a short history of the art of pantomimes.]
[Footnote 65: Ammianus, l. xiv. c. 6. He complains, with decent indignation that the streets of Rome were filled with crowds of females, who might have given children to the state, but whose only occupation was to curl and dress their hair, and jactari volubilibus gyris, dum experimunt innumera simulacra, quae finxere fabulae theatrales.]
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. ^66 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. ^67 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. ^68 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. ^69 III. Juvenal ^70 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 of Rome, since they might purchase, in the little towns of Italy, a cheerful commodious dwelling, at the same price which they annually paid for a dark and miserable lodging. House-rent was therefore immoderately dear: the rich acquired, at an enormous expense, the ground, which they covered with palaces and gardens; but the body of the Roman people was crowded into a narrow space; and the different floors, and apartments, of the same house, were divided, as it is still the custom of Paris, and other cities, among several families of plebeians. IV. The total number of
