Antium was an ancient coastal city of Latium, situated approximately 51 km south of Rome in the area now occupied by the modern towns of Anzio and Nettuno, Italy. Originally established by the Latial culture in the early 1st millennium BCE, Antium later emerged as the principal stronghold of the Volsci people before its conquest by the Roman Republic in 338 BCE. Under Roman rule, the city evolved into a prominent colonia and fashionable seaside resort, noted for its luxurious villas, harbor works, and cultural patronage. It was also the birthplace of emperors Caligula and Nero. In Roman mythology, Antium was said to have been founded by Anteias, a son of Odysseus.
The ancient Latin–Volscian town was situated on the Capo d'Anzio, an elevated area slightly inland from the coast, though its settlement extended to the shoreline. The site was naturally defensible, protected by a deep ditch—still partially visible—and fortified walls. A section of the eastern wall, built with rectangular blocks of tufa, was uncovered in 1897. [1]
The town's fortifications included an acropolis to the east, likely connected yet distinct from the main settlement. Archaeological evidence indicates that the Latin colony established in 467 BCE was built adjacent to this pre‐existing Volscian settlement. [2] [3]
The nearby port of Caenon served as Antium's harbor during its early period since the town itself lacked a natural harbor. The precise location of Caenon is debated: it may have been on the Capo d'Anzio, further north, or on a hill near Nettuno with a port at the mouth of the river Loricina. [4] [5] [6] During the Neronian period, substantial artificial harbor installations were constructed, the remains of which are still visible today. [7]
Roman Antium was centered at Capo d'Anzio—especially from the mid-Republican period onward, with the imperial colony and Nero's harbor—but may have coexisted with an earlier agricultural settlement near modern Nettuno. From 60 CE, Nero's colonia Antium in Capo d'Anzio likely existed alongside an older civitas Antium in Nettuno, which appears to have remained inhabited into the 4th century CE. [2] [8] This dual‐settlement theory has met with some skepticism and opposition. [9] [10]
Archaeological evidence indicates human occupation in the area dating back to the 11th century BCE, associated with the Latial culture. The nature and extent of this early settlement remain subjects of ongoing research. [2]
Antium served as the capital of the Antiates Volsci on the Tyrrhenian coast. [11] In 493 BCE—possibly marking the Volscian settlement—the Roman consul Postumus Cominius Auruncus defeated two armies from Antium and captured the nearby towns of Longula, Pollusca, and Corioli. [12]
According to Plutarch, the Roman leader Coriolanus fled to Antium and was hosted by the Volscian noble Attius Tullus Aufidius, though he was ultimately assassinated. [13]
In 469 BCE, the port of Caenon was destroyed by the Roman consul Titus Numicius Priscus. In 468 BCE, Titus Quinctius Capitolinus Barbatus captured Antium, and in 467 BCE a Latin colony was established. The allocation of lands was managed by ex‐consuls Aulus Verginius Tricostus Caeliomontanus, Publius Furius Medullinus Fusus, and Capitolinus himself. [14]
In 464 BCE, the Antiates were suspected of conspiring with the Aequi. Their explanations were deemed unsatisfactory, and although ordered to provide troops, their forces arrived too late. [15]
In 338 BCE, Antium was decisively defeated; its warships were seized or burned, and navigation from the town was banned. The bronze rostra of the destroyed ships were mounted in the Roman Forum, giving the speaker's platform its name. [16]
After 338 BCE, Antium became a Roman colony and was designated a municipium in 317 BCE. [17] Its local governance was administered by duumvirs [18] and quaestors. [3] During the civil wars, Antium—an important supplier of grain—aligned with Sulla but was attacked and devastated by Marian forces in 87 BCE. [19] [2]
Antium reached its zenith during the early Imperial period. It became a resort town for the Roman elite, and the imperial villa, known as the Domus Neroniana, extended about 800 metres (2,600 ft) along Capo d'Anzio. [20] Augustus was acclaimed Pater patriae there, and both Caligula and Nero were born in the town. Nero later rebuilt the imperial villa and constructed a theater. In 60 CE, he founded a veterans' colony and built substantial harbor installations whose piers are still extant. [21] Antium is also renowned for its artistic treasures, including the Fanciulla d'Anzio , the Borghese Gladiator (now in the Louvre), and the Apollo Belvedere (in the Vatican Museums).
Several bishops from Antium are documented as having attended synods in Rome, including Gaudentius (465), Felix (487), and Vindemius (499 and 501). Invasions during the 6th century led to the end of Antium as a residential bishopric; it is now recognized as a titular see. [22]
Antium was later attacked by the Vandals under Gaiseric, the Goths under Vitiges, and by Saracen raiders. [7] These incursions contributed to its decline in favor of Nettuno, which eventually inherited much of Antium's legacy. [20] Though often described as a medieval foundation, [10] Nettuno was later viewed in both early modern and modern eras as the successor to ancient Antium. [23] [2]
No physical trace remains of the famed temple to Fortuna—mentioned by Horace in Odes (i.35)—although it is presumed to have stood near the Domus Neroniana. [20] [2] [9]
Various other religious structures have been identified within the archaeological area, though many remain poorly documented.
Antium has yielded several masterpieces of ancient sculpture, including:
Systematic archaeological investigations have been conducted periodically since the 18th century, with major campaigns occurring in the late 19th and 20th centuries.
