20. The aqueducts for supplying the city with water, were still more worthy of admiration; they were supported by arches, many of them a hundred feet high, and carried over mountains and morasses that might have appeared insuperable. The first aqueduct was erected by Ap'pius Clo'dius, the censor, four hundred years after the foundation[Pg. 29]
of the city; but under the emperors there were not less than twenty of these useful structures, and such was the supply of water, that rivers seemed to flow through the streets and sewers. Even now, though only three of the aqueducts remain, such are their dimensions that no city in Europe has a greater abundance of wholesome water than Rome.
21. The Cloa'cæ, or common sewers, attracted the wonder of the ancients themselves; the largest was completed by Tarquin the Proud. The innermost vault of this astonishing structure forms a semicircle eighteen Roman palms wide, and as many high: this is inclosed in a second vault, and that again in a third, all formed of hewn blocks of pepenno, fixed together without cement. So extensive were these channels, that in the reign of Augustus the city was subterraneously navigable.
22. The public roads were little inferior to the aqueducts and Cloa'cæ in utility and costliness; the chief was the Appian road from Rome to Brundu'sium; it extended three hundred and fifty miles, and was paved with huge squares through its entire length. After the lapse of nineteen centuries many parts of it are still as perfect as when it was first made.
23. The Appian road passed through the following towns; Ari'cia, Fo'rum Ap'pii, An'xur or Terraci'na, Fun'di, Mintur'næ, Sinue'ssa, Cap'ua, Can'dium, Beneven'tum, Equotu'ticum, Herdo'nia, Canu'sium, Ba'rium, and Brundu'sium. Between Fo'rum Ap'pii and Terraci'na lie the celebrated Pomptine marshes, formed by the overflowing of some small streams. In the flourishing ages of Roman history these pestilential marshes did not exist, or were confined to a very limited space; but from the decline of the Roman empire, the waters gradually encroached, until the successful exertions made by the Pontiffs in modern times to arrest their baleful progress. Before the drainage of Pope Sixtus, the marshes covered at least thirteen thousand acres of ground, which in the earlier ages was the most fruitful portion of the Italian soil.
