Sinuessa is traditionally included in the list of five cities that made up the Aurunca Pentapolis (Ausona, Vescia, Minturnae, Suessa, Sinuessa). PRE-ROMAN The Aurunca Pentapolis is a fundamental concept for understanding the pre-Roman history of the territory stretching from southern northern Lazio to Campania beyond the Volturno, the area you are interested in (from Circeo to Sinuessa, up to the Liri). Here is a summary of its main characteristics: What is the Aurunca Pentapolis? Nature: It was a supposed federation or league of five city-states of the Aurunci people (or Ausoni, Oscan-speaking Italic peoples, whose distinction is still debated by scholars). Purpose: The alliance presumably had political and military purposes, particularly to defend the territory from the expansionist ambitions of Rome and the Samnites, especially during the Samnite Wars (4th century BC). Historical Location: The cities were located on the plains and hills of the fertile region of Latium Adiectum (as Pliny the Elder called it, extending to Circeo), between the Liri/Garigliano and Volturno rivers. The Five Cities Traditionally Included The five cities that, according to historiographical tradition (primarily based on Livy), formed the Pentapolis were: Ausona (or Aurunca, perhaps the capital, whose location is uncertain, often identified with modern-day Ausonia or a site on Mount Falerio). Vescia (destroyed, located in the coastal area, whose territory was later used for the foundation of Sinuessa). Minturnae (near the mouth of the Liri River, now Minturno). Suessa (now Sessa Aurunca). Sinuessa (the coastal town that, although mentioned as part of the Pentapolis, later became the Roman colony founded on the territory of Vescia). Fate under Rome The fate of the Pentapolis was tragic and marked the end of Auruncan independence: Destruction (314 BC): During the Second Samnite War, the cities of Ausona, Minturnae, and Vescia were destroyed by the Romans in a particularly violent manner (a "genocide" according to some sources), putting an end to Auruncan resistance. Roman Refoundation: Rome refounded the strategic centers for control of the territory and the Appian Way (the construction of which, let's always remember, began in 312 BC): Suessa Aurunca: Refounded as a Latin colony in 313 BC. (the later Sessa Aurunca). Minturnae and Sinuessa: Refounded as maritime Roman colonies in 296 BC.
Hannibal, whose cavalry carried their devastations up to the very gates of the town. It subsequently endeavored, in common with Minturnae and other
coloniae maritimae, to establish its exemption from furnishing military levies; but this was overruled, while there was an enemy with an army in Italy. At a later period (191 BCE) Sinuessa again attempted, but with equal ill success, to procure a similar exemption from the naval service. Its position on the
Appian Way doubtless contributed greatly to the prosperity of Sinuessa; for the same reason it is frequently incidentally mentioned by
Cicero, and we learn that
Julius Caesar halted there for a night on his way from
Brundisium to
Rome, in 49 BCE. It is noticed also by
Horace on his journey to Brundusium, as the place where he met with his friends
Varius and
Virgil. The fertility of its territory, and especially of the neighbouring ridge of the Mons Massicus, so celebrated for its wines, must also have tended to promote the prosperity of Sinuessa, but we hear little of it under the
Roman Empire. It received a body of military colonists, apparently under the Triumvirate, but did not retain the rank of a colonia and is termed by Pliny as well as the
Liber Coloniarum only an
oppidum, or ordinary municipal town. It was the furthest town in Latium, as that geographical term was understood in the days of Strabo and Pliny, or
Latium adjectum, as the latter author terms it; and its territory extended to the river
Savo, which formed the limit between Latium and
Campania. At an earlier period indeed
Polybius reckoned it a town of Campania, and
Ptolemy follows the same classification, as he makes the
Liris the southern limit of Latium; but the division adopted by Strabo and Pliny is probably the most correct. The
Itineraries all notice Sinuessa as a still existing town on the Appian Way, and place it nine miles from Minturnae, which is, however, considerably short of the true distance. In his
Meditations, written around AD 180, the emperor
Marcus Aurelius notes that his friend
Junius Rusticus sent a letter to
Marcus's mother from Sinuessa. The city was the (purported) location of the
Pseudo-Council of Sinuessa in AD 303. The period of its actual destruction is unknown. ==Ruins==
