12. Immediately after passing Idubeda, you enter on Keltiberia, a large and irregular country. It is for the most part rugged, and watered by rivers, being traversed by the Guadiana,[1233] the Tagus, and many other of the rivers which flow into the western sea, but have their sources in Keltiberia. Of their number is the Douro, which flows by Numantia[1234] and Serguntia. The Guadalquiver[1235] rises in Orospeda, and after passing through Oretania, enters Bætica. The Berones inhabit the districts north of the Keltiberians, and are neighbours of the Conish Cantabrians. They likewise had their origin in the Keltic expedition. Their city is Varia,[1236] situated near to the passage of the Ebro. They are adjacent to the Bardyitæ, now called the Bardyli.[1237] To the west [of the Keltiberians] are certain of the Astures, Gallicians, and Vaccæi, besides Vettones and Carpetani. On the south are the Oretani, and the other inhabitants of Orospeda, both Bastetani and Edetani,[1238] and to the east is Idubeda. 13. Of the four divisions into which the Keltiberians are separated, the most powerful are the Aruaci, situated to the east and south, near to the Carpetani and the sources of the Tagus. Their most renowned city is Numantia. They showed their valour in the war of twenty years, waged by the Keltiberians against the Romans; for many armies of the Romans, together with their generals, were destroyed; and in the end the Numantians, besieged within their city, endured the famine with constancy, till, reduced to a very small number, they were compelled to surrender the place. The Lusones are also situated to the east, and likewise border on the sources of the Tagus. Segeda and Pallantia[1239] are cities of the [CAS. 162] Aruaci. Numantia is distant from Cæsar Augusta,[1240] situated as we have said upon the Ebro, about 800 stadia. Near to Segobriga and Bilbilis,[1241] likewise cities of the Keltiberians, was fought the battle between Metellus and Sertorius. Polybius, describing the people and countries of the Vaccæi and Keltiberians, enumerates Segesama[1242] and Intercatia amongst their other cities. Posidonius tells us that Marcus Marcellus exacted of Keltiberia a tribute of 600 talents, which proves that the Keltiberians were a numerous and wealthy people, notwithstanding the little fertility of their country. Polybius narrates that Tiberius Gracchus destroyed 300 cities of the Keltiberians. This Posidonius ridicules, and asserts that to flatter Gracchus, Polybius described as cities the towers such as are exhibited in the triumphal processions.[1243] This is not incredible; for both generals and historians easily fall into this species of deception, by exaggerating their doings. Those who assert that Iberia contained more than a thousand cities, seem to me to have been carried away in a similar manner, and to have denominated as cities what were merely large villages; since, from its very nature, this country is
