The Arverni extended over a vast region, comprising the present departments of the Puy-de-Dôme and Cantal, and part of those of the Allier and the Upper Loire. Gergovia was their principal town. The Arverni had for clients—
The Cadurei Eleutheri, whose territory answered to the ancient Quercy (department of the Lot). [This epithet of Eleutheri, which is found in Cæsar (De Bello Gallico, VIII. 75) leads us to believe that in southern Quercy there existed Cadurci placed under the dominion of Rome.]
The Gabali, who occupied the ancient Gévaudan (the department of the Lozère).
The Vellavi, whose territory answered to the ancient Velay (department of the Upper Loire).
The Aulerci formed an extensive nation, which was subdivided into three great tribes, established over the country from the lower course of the Seine to the Mayenné.
1. The Aulerci Cenomanni, a fraction of whom was, as early as the sixth century of Rome, established in Cisalpine Gaul, between the Oglio and the Adige, and who occupied in Gaul the greater part of the territory now forming the department of the Sarthe;
2. The Aulerci Diablintes, the northern and central parts of the department of the Mayenne.
3. The Aulerci Eburovices, the central and southern part of the department of the Eure.
The Bituriges, a nation which had more than twenty towns. Avaricum (Bourges) was the principal. Their territory embraced the ancient Berry (departments of the Cher, the Indre, and part of the Allier).
The Carnutes occupied the greatest part of the present departments of Eure-et-Loir, Loir-et-Cher, and Loiret. Genabum (Gien) was one of their most important towns.
