Province of Barletta-Andria-Trani in the context of "Province of Bari"

The Gravina (also called Gravina di Picciano) is a river in the Apulia and Basilicata regions of southern Italy. Its source is near Poggiorsini and the border of the province of Barletta-Andria-Trani in the province of Bari. The river flows southeast near Gravina in Puglia before crossing into the province of Matera. It flows west of Matera before emptying into the Bradano as a left tributary a short distance after the Bradano exits Lago di San Giuliano.

The Daunians (Latin: Daunii) were an Iapygian tribe that inhabited northern Apulia in classical antiquity. Two other Iapygian tribes, the Peucetians and the Messapians, inhabited the central and southern Apulia respectively. Although all three tribes spoke the Messapic language, they had developed separate archaeological cultures by the seventh century BC.

The Daunians lived in the Daunia region, which extended from the Daunian Mountains river in the southeast to the Gargano peninsula in the northwest. This region is mostly coincident with the Province of Foggia and part of Province of Barletta-Andria-Trani today. Daunians and Oscans came into contact in northern Daunia and southern Samnite regions. Gradually, parts of northern Daunia became "Oscanized".

The Peucetians were an Iapygian tribe which inhabited western and central Apulia in classical antiquity.

Two other Iapygian tribes, the Daunians and the Messapians, inhabited northern and southern Apulia respectively. All three tribes spoke the Messapian language, but had developed separate archaeological cultures by the seventh century BC; however, in Peucetian territory ancient Greek and Oscan language were spoken as well, as the legends of the currencies from Rubi and Azetium were trilingual. Peucetians lived in the eponymous region Peucetia, which was bordered by the Ofanto river and the Murge in the north, the Bradano river in the west and the territories of the Greek colony of Taras and the Messapians in the south. This region is mostly coincident with the Metropolitan City of Bari and parts of the provinces of Taranto and Barletta-Andria-Trani today.

Canosa di Puglia, generally known simply as Canosa (Canosino: Canaus), is a town and comune in the province of Barletta-Andria-Trani, Apulia, southern Italy. It is located between Bari and Foggia, on the northwestern edge of the plateau of the Murgia which dominates the Ofanto valley and the extensive plains of Tavoliere delle Puglie, ranging from Mount Vulture at the Gargano, to the Adriatic coast. Canosa, the Roman Canusium, is considered the principal archaeological center of Apulia, and is one of the oldest continually inhabited cities in Italy. A number of vases and other archaeological finds are located in local museums and private collections. It is not far from the position on the Ofanto River where the Romans found refuge after the defeat of the Battle of Cannae and is the burial place of Bohemund I of Antioch.
