The Romans borrowed the plan of their theatres from the Greeks; their amphitheatres, however, were original with them. The Flavian Amphitheatre, known as the Colosseum, has already come under our notice (see p. 316). The edifice was 574 feet in its greatest diameter, and was capable of seating eighty-seven thousand spectators. The ruins of this immense structure stand to-day as "the embodiment of the power and splendor of the Roman Empire."
AQUEDUCTS.—The aqueducts of ancient Rome were among the most important of the utilitarian works of the Romans. The water-system of the capital was commenced by Appius Claudius (about 313 B.C.), who secured the building of an aqueduct which led water into the city from the Sabine hills. During the republic four aqueducts in all were completed; under the emperors the number was increased to fourteen. [Footnote: Several of these are still in use.] The longest of these was about fifty-five miles in length. The aqueducts usually ran beneath the surface, but when a depression was to be crossed, they were lifted on arches, which sometimes were over one hundred feet high. These lofty arches running in long broken lines over the plains beyond the walls of Rome, are the most striking feature of the Campagna at the present time.
THERMÆ, OR BATHS.—The greatest demand upon the streams of water poured into Rome by the aqueducts was made by the Thermæ, or baths. Among the ancients Romans, bathing, regarded at first simply as a troublesome necessity, became in time a luxurious art. Under the republic, bathing- houses were erected in considerable numbers. But it was during the imperial period that those magnificent structures to which the name of Thermæ properly attaches, were erected. These edifices were among the most elaborate and expensive of the imperial works. They contained chambers for cold, hot, tepid, sudatory, and swimming baths; dressing-rooms and gymnasia; museums and libraries; covered colonnades for lounging and conversation, extensive grounds filled with statues and traversed by pleasant walks; and every other adjunct that could add to the sense of luxury and relaxation. Being intended to exhibit the liberality of their builders, they were thrown open to the public free of charge.
MEMORIAL ARCHITECTURE.—Among the memorial structures of the Romans, their triumphal arches are especially characteristic. These were modelled after the city gates, being constructed with single and with triple archways. Two of the most noted monuments of this character, and the most interesting because of their historic connections, are the Arch of Titus (see p. 315) and the Arch of Constantine, both of which are still standing. The Arch of Constantine was intended to commemorate the victory of that emperor over his rival Maxentius, which event established Christianity as the imperial and favored religion of the empire.

2. LITERATURE, PHILOSOPHY, AND LAW.
RELATION OF ROMAN TO GREEK LITERATURE: THE POETS OF THE REPUBLICAN ERA.— Latin literature was almost wholly imitative or borrowed, being a reproduction of Greek models; still it performed a most important service for civilization: it was the medium for the dissemination throughout the world of the rich literary treasures of Greece.
It was the dramatic productions of the Greeks which were first studied and copied at Rome. Livius Andronicus, Nævius, Ennius, Plautus, and Terence, all of whom wrote under the republic, are the most noted of the Roman dramatists. Most of their plays were simply adaptations or translations of Greek masterpieces.
Lucilius (born 148 B.C.) was one of the greatest of Roman satirists. The later satirists of the corrupt imperial era were his imitators. Besides Lucilius, there appeared during the later republican era only two other poets of distinguished merit, Lucretius and Catullus. Lucretius (95-51 B.C.) was an evolutionist, and in his great poem, On the Nature of Things, we find anticipated many of the conclusions of modern scientists.
