Note 41 — LIFE OF TIBERIUS GRACCHUS.
George Long translation
The Romans used the words Iberia and Hispania indifferently to denote the Spanish Peninsula. From the word Hispania the Spaniards have formed the name España, the French Espagne, and the English Spain. The river Ebro, which the Romans called Iberus, is a remnant of this old name. The Iberi originally occupied a part of Southern Gaul (the modern France) as far east as the Rhone, where they bordered upon the Ligurians. They were a different people from the Celtæ, who in the time of C. Julius Cæsar occupied one of the three great divisions of Gaul. (Gallic War, i. 1.) The Celtæ, at some unknown time, crossed the Pyrenees and mingling with the Iberi, formed the Celtiberi, a warlike race with whom the Romans had many wars, and over whom Tiberius, the father of Tiberius Gracchus, gained a victory. (Note, c. 1.) It is maintained by William Humboldt in his work on the original inhabitants of Spain (Prüfung der Untersuchungen über die Urbewohner Hispaniens) that the present Basque is a remnant of the Iberian language, which he supposes not to have been confined to Spain, but to have spread over part of Italy, the south of France, and the islands of Sicily, Sardinia, and Corsica. Thucydides (vi. 2) says that the Sicani, or old inhabitants of Sicily, were Iberi who were driven from the river Sicanus in Iberia by the Ligurians.
The name Iberia was also given by the Greeks and Romans to a part of that mountainous region, commonly called the Caucasus, which lies between the Black Sea and the Caspian Sea. The Albani and Iberi were the two chief nations that occupied this tract; the Albani were between the Caspian Sea and the Iberi, who were their neighbours on the west. The great river Cyrus (Kur) flowed through Albania into the Caspian. Iberia was partly surrounded by the mountains of the Caucasus and it bordered on Armenia and Colchis: the river Cyrus was the chief river (Strabo, 499, ed. Casaub.). There is no evidence that these Iberi of the Caucasus were related to the western Iberi. The country was invaded by the Romans under L. Lucullus and Pompeius Magnus.
