Roman amphitheatres are theatres — large, circular or oval open-air venues with raised seating — built by the ancient Romans. They were used for events such as gladiator combats, venationes (animal slayings) and executions. About 230 Roman amphitheatres have been found across the area of the Roman Empire. Early amphitheatres date from the Republican period, though they became more monumental during the Imperial era.
Amphitheatres are distinguished from circuses and hippodromes, which were usually rectangular and built mainly for racing events, and stadia, built for athletics, but several of these terms have at times been used for one and the same venue. The word amphitheatrum means "theatre all around". Thus, an amphitheatre is distinguished from the traditional semicircular Roman theatres by being circular or oval in shape.
Components
The Roman amphitheatre consists of three main parts: the cavea, the arena, and the vomitorium. The seating area is called the cavea (Latin for "enclosure"). The cavea is formed of concentric rows of stands which are either supported by arches built into the framework of the building, or simply dug out of the hillside or built up using excavated material extracted during the excavation of the fighting area (the arena).
The cavea is traditionally organised in three horizontal sections, corresponding to the social class of the spectators:
The ima cavea is the lowest part of the cavea and the one directly surrounding the arena. It was usually reserved for the upper echelons of society. The media cavea directly follows the ima cavea and was open to the general public, though mostly reserved for men. The summa cavea is the highest section and was usually open to women and children.
Similarly, the front row was called the prima cavea and the last row was called the cavea ultima. The cavea was further divided vertically into cunei. A cuneus (Latin for "wedge"; plural, cunei) was a wedge-shaped division separated by the scalae or stairways.
The arched entrances both at the arena level and within the cavea are called the vomitoria (Latin "to spew forth"; singular, vomitorium) and were designed to allow rapid dispersal of large crowds.
History
Early amphitheatres
It is uncertain when and where the first amphitheatres were built. There are records attesting to temporary wooden amphitheatres built in the Forum Romanum for gladiatorial games from the second century BC onwards, and these may be the origin of the architectural form later expressed in stone. In his Historia Naturalis, Pliny the Elder claims that the amphitheatre was invented during the spectacles of Gaius Scribonius Curio in 53 BC, where two wooden semicircular theatres were rotated towards each other to form one circular amphitheatre, while spectators were still seated in the two halves. But while this may be the origin of the architectural term amphitheatrum, it cannot be the origin of the architectural concept, since earlier stone amphitheatres, known as spectacula or amphitheatera, have been found.
According to Jean-Claude Golvin, the earliest known stone amphitheatres are found in Campania, at Capua, Cumae and Liternum, where such venues were built towards the end of the second century BC. The next-oldest amphitheatre known, as well as one of the best-researched, is the amphitheatre of Pompeii, securely dated to be built shortly after 70 BC. There are relatively few other known early amphitheatres: those at Abella, Teanum and Cales date to the Sullan era (until 78 BC), those at Puteoli and Telesia from the Augustan (27 BC–14 AD). The amphitheatres at Sutrium, Carmo and Ucubi were built around 40–30 BC, those at Antioch and Phaestum (Phase I) in the mid-first century BC.
Imperial era
In the Imperial era, amphitheatres became an integral part of the Roman urban landscape. As cities vied with each other for preeminence in civic buildings, amphitheatres became ever more monumental in scale and ornamentation. Imperial amphitheatres comfortably accommodated 40,000–60,000 spectators, or up to 100,000 in the largest venues, and were only outdone by the hippodromes in seating capacity. They featured multi-storeyed, arcaded façades and were elaborately decorated with marble and stucco cladding, statues and reliefs, or even partially made of marble.
