6. After Abdera[1181] is New Carthage,[1182] founded by Asdrubal, who succeeded Barcas, the father of Hannibal. It is by far the most powerful city of this country, being impregnable, and furnished with a noble wall, harbours, and a lake, besides the silver mines already mentioned. The places in the vicinity have an abundance of salted fish, and it is besides the great emporium of the sea merchandise for the interior, and likewise for the merchandise from the interior for exportation. About midway along the coast between this city and the Ebro, we meet with the outlet of the river Xucar,[1183] and a city bearing the same name.[1184] It rises in a mountain belonging to the chain which overlooks Malaca,[1185] and the regions around Carthage, and may be forded on foot; it is nearly parallel to the Ebro, but not quite so far distant from Carthage as from the Ebro. Between the Xucar and Carthage are three small towns of the people of Marseilles, not far from the river. Of these the best known is Hemeroscopium.[1186] On the promontory there is a temple to Diana of Ephesus, held in great veneration. Sertorius used it as an arsenal, convenient to the sea, both on account of its being fortified and fitted for piratical uses, and because it is visible from a great distance to vessels approaching. It is called Dianium,[1187] from Diana. Near to it are some fine iron-works, and two small islands, Planesia[1188] and Plumbaria,[1189] with a sea-water lake lying above, of 400 stadia in circumference. Next is the island of Hercules, near to Carthage, and called Scombraria,[1190] on account of the mackerel taken there, from which the finest garum[1191] is made. It is distant 24 stadia from Carthage. On the other side of the Xucar, going towards the outlet of the Ebro, is Saguntum, founded by the Zacynthians. The destruction of this city by Hannibal, contrary to his treaties with the Romans, kindled the second Punic war. Near to it are the cities of Cherronesus,[1192] Oleastrum, and Cartalia, and the colony of Dertossa,[1193] on the very passage of the Ebro. The Ebro takes its source amongst the Cantabrians; it flows through an extended plain towards the south, running parallel with the Pyrenees.
