The city had a famous name. Argos was the great city of the Peloponnese, associated with heroes, kings, and centuries of Greek legend. Amphilochian Argos borrowed that name deliberately, claiming an Argive founder and Argive ancestry — a genealogy that put it in the company of the most celebrated places in the Greek world. The catch was that Thucydides, writing in the 5th century BC, classified the Amphilochi as barbarians, meaning they did not yet speak standard Greek. Their city was the one exception: only the inhabitants of Amphilochian Argos had become hellenized, he wrote, and they owed that to Ambraciot settlers who had moved in and brought the language with them. The gap between the name the city claimed and the culture Thucydides observed is itself a story — about how identity was constructed on the edges of the ancient Greek world.
Ancient cities rarely had just one origin legend, and Amphilochian Argos had two. In the first, the city was founded by Amphilochus, son of the seer Amphiaraüs, after the Trojan War. Dissatisfied with conditions in Peloponnesian Argos when he returned from Troy, Amphilochus sailed to the Ambracian Gulf and founded a new city, naming it after his homeland and calling the whole region Amphilochia after himself. The second version attributed the founding not to Amphilochus but to Alcmaeon — another figure from the mythological cycle of the Argive royal house — who named the city after his brother. The two stories are not irreconcilable; they may represent different traditions about the same founding era. What both versions agree on is the city's claim to Argive descent and a heroic founder connected to some of the most dramatic events in Greek myth.
Thucydides' characterization of the Amphilochi as barbarians is striking and has generated considerable scholarly debate. He was careful to define his terms: the criterion was language, and perhaps culture, not ethnicity. The Amphilochians spoke a dialect sufficiently different from standard Greek that Athenian contemporaries marked it as alien. The inhabitants of Amphilochian Argos were the exception precisely because Ambraciot settlers had joined the city and brought their language. Thucydides contrasts the "Greek Ambrakiotes" with the "barbarian Amphilochians" while acknowledging the Amphilochians' Greek heritage — his use of the term reflects a 5th-century Athenian perspective in which dialect and cultural practice could place communities outside the Greek mainstream even when their ethnic origins were not in question. Modern scholars note that the neighboring Aetolians and Acarnanians faced similar characterizations, despite being Greek-speaking, suggesting the label said as much about Athenian cultural hierarchies as about the populations described.
After Alexander the Great's death in 323 BC, Amphilochian Argos fell to the Aetolians along with the rest of Ambracia. It was at Argos that the Roman general Marcus Fulvius Nobilior established his headquarters when he negotiated the treaty between Rome and the Aetolian League in 189 BC — a moment when the city, still standing on its site at the head of the Ambracian Gulf, served as the venue for an agreement that would reshape the eastern Mediterranean. That quiet importance ended with Augustus. After his victory at the Battle of Actium in 31 BC, Augustus founded Nicopolis nearby as a monument to that triumph. The new city needed settlers, and the inhabitants of Argos — along with those of several other communities in the region — were moved there. Argos was abandoned. It did not fall in battle; it was simply emptied.
Where exactly Amphilochian Argos stood has been debated for centuries. Thucydides placed it on the sea. Polybius said it was 180 stadia from Ambracia; Livy gave the distance as 22 miles. William Martin Leake, the 19th-century British explorer and geographer who systematically identified many ancient Greek sites, placed it in the plain of Vlikha, at the modern village of Neokhori, where the ruins of an ancient city with walls about a mile in circumference could still be seen. The editors of the Barrington Atlas of the Greek and Roman World — the standard modern reference for ancient geography — tentatively identify a place called Ag. Ioannes, near Neokhori, as the probable site. The ruins of Amphilochian Argos, if that is what they are, lie at the head of the Ambracian Gulf, where a city that called itself Argos once faced the water and told a story about Troy.
Amphilochian Argos is located at approximately 38.89°N, 21.35°E, near the head of the Ambracian Gulf (also called the Gulf of Arta) in western Greece. The nearest airport is LGPZ (Aktion National Airport), about 25 km to the northwest on the southern shore of the gulf. From the air, the Ambracian Gulf is immediately recognizable — a nearly enclosed body of water connected to the Ionian Sea by a narrow strait near Preveza. The ancient site near Neokhori lies on the eastern shore of the gulf, in a coastal plain backed by hills. Flying at 5,000–8,000 feet provides a clear view of the gulf's full extent, the fertile plain of the Arachthos River delta to the north, and the low ridgelines of Acarnania to the south. Visibility across the gulf is excellent in summer.
