⭐ In the context of Lucania, the Gravina river is considered…
Lucania's eastern border was explicitly defined by the Gravina river, which flows into the Gulf of Taranto, as stated in the historical description of the region's limits.
The precise limits were the river Silarus in the north-west, which separated it from Campania, and the Gravina which flows into the Gulf of Taranto in the east. The lower tract of the river Laus, which flows from a ridge of the Apennine Mountains to the Tyrrhenian Sea in an east-west direction, marked part of the border with Bruttium.
Matera (Italian pronunciation:[maˈtɛːra], locally[maˈteːra]; Materano: Matàrë[maˈtæːrə]) is a city and the capital of the Province of Matera in the region of Basilicata, in Southern Italy. With a history of continuous occupation dating back to prehistory (the eighth millennium BC), it is renowned for its rock-cut urban core, whose twin cliffside zones are known collectively as the Sassi.
Matera lies on the right bank of the Gravina river, whose canyon forms a geological boundary between the hill country of Basilicata (historic Lucania) to the southwest and the Murgia plateau of Apulia to the northeast. The city began as a complex of cave habitations excavated in the softer limestone on the gorge's western, Lucanian face. It took advantage of two streams that flow into the ravine from a spot near the Castello Tramontano, reducing the cliff's angle of drop and leaving a defensible narrow promontory between the streams. The central high ground, or acropolis, supporting the city's cathedral and administrative buildings, came to be known as Civita, and the settlement districts scaling down and burrowing into the sheer rock faces as the Sassi. Of the two streambeds, called the grabiglioni [it], the northern hosts Sasso Barisano (facing Bari) and the southern Sasso Caveoso (facing Montescaglioso).
The word gravina comes from the Latin grava or from the messapic graba, with the meaning of rock, shaft and erosion of bank river. Other words that share the same root are grava, gravaglione and gravinelle. Alternatively, when the emperor Frederick II went to Gravina, because of the large extension of the lands and for the presence of wheat, he decided to give to it the motto Grana dat et vina., that is to say It offers wheat and wine.. Gravina is the home of the Alta Murgia National Park.
