Pliny Natural History, Vol. II (Loeb Latin-English)

...Lusitania, and that Pan was its governor. However, the accounts passed down regarding Hercules, Pyrene, or Saturn, I consider to be primarily fabulous.

9 The Baetis river rises in the Tarraconensis province—not at the town of Mentesa, as some have said, but in the Tugien saltus (near which is the Tader river, which waters the territory of Carthage). At Ilorca, it avoids the pyre of Scipio, and turning west, it makes for the Atlantic Ocean, adopting the province as it goes. It is small at first but capable of absorbing many rivers, from which it takes both its fame and its waters. Upon entering Baetica at Ossigetania, it flows through a pleasant channel, flanked on both right and left by numerous towns.

10 Between this river and the ocean coast, the most famous towns in the interior are: Segida (surnamed Augurina), Julia (surnamed Fidentia), Urgao (surnamed Alba), Ebura (surnamed Cerialis), Iliberri (called Liberini), Ilipula (surnamed Laus), Artigi (called the Julienses), Vesci (called Faventia), Singili, Ategua, Arialdunum, Agla Minor, Baebro, Castra Vinaria, Cisimbrium, Hippo Nova, Illurco, Osca, Oscua, Sucaelo, Unditanum, and Tucci Vetus—all in the region of Bastetania, which slopes toward the sea. The jurisdiction of Cordova includes, around the river itself: Ossigi (surnamed Latonium), Iliturgi (called Forum Julium), Ipra, Isturgi (called Triumphale), Sucia, and, 17 miles inland, Obulco (called Pontificense); then Ripa, Epora (a treaty town), Sacili Martialium, Onuba, and, on the right, the colony of Corduba (surnamed Patricia). From there, the Baetis is first navigable, passing the towns of Carbula, Decuma, and the river Singilis, which joins the Baetis on the same side.
