The ancient Greek city of Epidamnus or Epidamnos (Ἐπίδαμνος) (Strabo Geography vi.316), later the Roman Dyrrachium (modern Durrës, Albania, ca. 30 km W of Tirana) was founded in 627 BCE in Illyria by a group of colonists from Corinth and Corcyra (modern Corfu). Aristotle's Politics several times draws for examples on the internal government of Epidamnos, which was run as a tight oligarchy that appointed a ruling magistrate; tradesmen and craftsmen were excluded from power, until internal strife produced a more democratic government. The exiled oligarchs appealed to Corcyra while the democrats enlisted the help of Corinth, initiating a struggle between the two mother cities described by Thucydides as a cause of the Peloponnesian War. Individual trading with the local Illyrians was forbidden at Epidamnos: all traffic was through the authorized city agent or poletes. In the fourth century BCE the city-state was part of the kingdoms of Cassander and Pyrrhus. The general vicinity of Epidamus was called Epidamnia.
In 229 BCE, when the Romans seized the city the "-damnos" part of the name was inauspicious to Latin ears, and its name, as it was refounded, became Dyrrhachium. Pausanias (6.x.8) says "the modern Roman city is not the ancient one, being at a short distance from it. The modern city is called Dyrrhachium from its founder." The name Dyrrachion is found on coins of the fifth century BCE; in the Roman period Dyrrachium was more common. However, the city maintained a semi-autonomy and was turned into a Roman colony.
Dyrrachium was the landing place for Roman passengers crossing the Ionian Sea from Brundisium, which made it a fairly busy way-station. Here commenced the Via Egnatia, the Roman military road to Thessalonica that connected Roman Illyria with Macedonia and Thrace. The city itself was part of Macedonia, more specifically Epirus Nova. In 48 BCE Pompey was based at Dyrrachium and beat off an attack by Julius Caesar (see Battle of Dyrrhachium). In 345 BCE the city was levelled by an earthquake and rebuilt on its old foundations. In the 4th century CE, Dyrrachium was made the capital of the Roman province of Epirus nova.
The modern city of Durrës is built directly over the ancient site, so it is primarily on the basis of inscriptions and serendipitous finds that some idea of its monuments has been formed. Inscriptions offer evidence on the following Roman monuments: an aqueduct constructed by Hadrian and restored by Alexander Severus bears a dedicatory inscription at Arapaj, a short distance from Durazzo: (Corpus Inscriptionum Latinarum III, 1-709); the Roman temple of Minerva; the Temple of Diana (CIL III, 1-602), which is perhaps the one mentioned by Appian (BCiv. 2.60); the equestrian statue of L. Titinius Sulpicianus (CIL III, 1-605); the library (CIL m, 1-67). The last inscription mentions that for the dedication of the library 24 gladiators fought in pairs. The conjecture that there was an amphitheater in the city is confirmed by a passage from the fifteenth-century Vita di Skanderbeg by Marin Barleti: "amphitheatrum mira arte ingenioque constructum".
As a result of occasional discoveries, the following data are available: a 3rd-century mosaic pavement with a female head surrounded by garlands of vegetables and flowers, which brings to mind those painted on Apulian vases; remains of houses covered by other layers, the lowest of which, of the Greek era, was found at a depth of 5 m.
Columns with Corinthian capitals and sections of finished marble revetment, discovered on the nearby hillside at Stani, belong probably to the Temple of Minerva or to the Capitolium. In the necropolis east of the hills that stand above the city have been found a stele of Lepidia Salvia, a sarcophagus with a scene of the Calydonian Boar hunt (now at Istanbul), and numerous Roman tombs.
