The Aquitani were a tribe that lived in the region between the Pyrenees, the Atlantic Ocean, and the Garonne, in present-day southwestern France[1] in the 1st century BC.
Classical authors such as Julius Caesar and Strabo clearly distinguish the Aquitani from the other peoples of Gaul, and note their similarity to others in the Iberian Peninsula.
The river Garonne separates the Gauls from the Aquitani[3]Despite apparent cultural and linguistic connections to (Vascones), the region of Aquitania extended only to the Pyrenees according to Caesar: Aquitania extends from the river Garonne to the Pyrenaean mountains and to that part of the ocean which is near Hispania: it looks between the setting of the sun, and the north star.
[2] The fact that the region was known as the Vasconia in the Early Middle Ages, a name that evolved into the better known form of Gascony, along with other toponymic evidence, seems to corroborate that assumption.
Although the region where the original Aquitanians lived came to be named Novempopulania (nine peoples) in the late years of the Roman Empire and Early Middle Ages (up to the 6th century), the number of tribes varied (about 20 for Strabo, but comparing with the information of other classical authors such as Pliny, Ptolemy and Julius Caesar, the total number were 32 or 33):[citation needed] In the southern slopes of western Pyrenees Mountains, not in Aquitania but in northern Hispania Tarraconensis:
