The Adriatic Sea

Between the Italian peninsula and the Balkans · c. 500 BCE – 600 CE complete

Also known as: ho Adrías, Hadriāticum

The Adriatic is the long gulf of the Mediterranean reaching up between the Italian peninsula and the Balkan coast to the head of the sea near Venice. To the ancients it was a route and a hazard, proverbially stormy, the water that linked the Greek world to Italy and that the Romans crossed from Brundisium to Greece. At its northern end lay the silt-laden delta of the Po, and it is from that corner that the sea took its name.

The sea is named, by the Greeks, after a city: Adria (also Hatria or Atria), an Etruscan and Venetic port near the Po delta that was once on the coast and is now, with the silting of the shore, some kilometers inland. From the city the Greeks called the sea Adrías, and from the Greek came the Latin Hadria and mare Hadriāticum, with the H that Latin liked to add; through these the modern name descends. So the Po and the Adriatic knot together at the same delta: the river is the Eridanos of the amber-myth, and the sea bears the name of the Etruscan emporium at its mouth, a town the sea has since left behind. The Etruscans surely had their own name for the place and the water, but, as so often, none is recorded; the sea of the Etruscan port is known by the Greek and Latin words for it.

The Greek name of the sea, ho Adrías, “the Adriatic,” also expanded as Adriatikòn pélagos, “the Adriatic deep.” It is named after the city of Adria near the Po delta, a connection the Greeks made early; Hecataeus already derived sea and city from one another. To the Greeks the Adrías was the gulf running up the far side of Italy, the limit of their western sailing and the water beyond which lay the Veneti and the amber routes.

Adrías is the source of the sea’s name in every later language, and it carries a small irony. The Greeks named the whole long gulf after a single Etruscan-and-Venetic trading town at its northern corner, the port through which they knew the head of the sea; but that town, Adria, was slowly stranded inland as the Po piled up its delta around it, so that the sea is named for a place that is no longer on it. The greatest arm of the Mediterranean bears, in Greek, the name of a silted-up Etruscan harbor.

The Latin name of the sea, mare Hadriāticum, and in the poets simply Hadria, taken from the Greek, with the initial H that Latin added to the name. To Rome the Hadria was a byword for rough water: Horace calls it stormy and wrathful, “more violent than the wicked Adriatic,” and the crossing from Italy to Greece by way of it was a real danger.

Hadriāticum carries the Greek name on into the western languages, the form behind the modern “Adriatic.” It preserves the same buried city-name as the Greek, the Etruscan port of Adria, now the same word Latinized with an aspirate the Greeks did not write. The sea kept the name long after the harbor that gave it had been left inland; Rome sailed the Hadria and named it, as it named so much, with a Greek word dressed in Latin spelling.
