The country which extends from the Bætis to the river Anas, beyond the districts already described, is called Bæturia, and is divided into two parts and the same number of nations; the Celtici[917], who border upon Lusitania, in the jurisdiction of Hispalis, and the Turduli, who dwell on the verge[918] of Lusitania and Tarraconensis, and are under the protection of the laws of Corduba. It is evident that the Celtici have sprung from the Celtiberi, and have come from Lusitania, from their religious rites, their language, and the names of their towns, which in Bætica are distinguished by the following epithets[919], which have been given to them. Seria has received the surname of Fama Julia[920], Nertobriga that of Concordia Julia[921], Segida that of Restituta Julia[922], and Contributa[923] that of Julia. What is now Curiga was formerly Ucultuniacum, Constantia Julia[924] was Laconimurgis, the present Fortunales were the Tereses[925], and the Emanici were the Callenses[926]. Besides these, there are in Celtica the towns of Acinippo[927], Arunda[928], Aruci[929], Turobriga, Lastigi, Salpesa, Sæpone, and Serippo. The other Bæturia, which we have mentioned, is inhabited by the Turduli, and, in the jurisdiction of Corduba, has some towns which are by no means inconsiderable; Arsa[930], Mellaria[931], Mirobriga[932], and Sisapo[933], in the district of Osintias. To the jurisdiction of Gades belongs Regina, with Roman citizens; and Læpia, Ulia[934], Carisa[935] surnamed Aurelia, Urgia[936] or Castrum Julium, likewise called Cæsaris Salutariensis, all of which enjoy the Latian rights. The tributary towns are Besaro, Belippo[937], Barbesula, Lacippo, Bæsippo, Callet, Cappacum, Oleastro, Ituci, Brana, Lacibi, Saguntia[938], and Audorisæ. M. Agrippa has also stated the whole length of this province to be 475 miles[939], and its breadth 257; but this was at a time when its boundaries extended to Carthage[940], a circumstance which has often caused great errors in calculations; which are generally the result either of changes effected in the limits of provinces, or of the fact that in the reckoning of distances the length of the miles has been arbitrarily increased or diminished. In some parts too the sea has been long making encroachments upon the land, and in others again the shores have advanced; while the course of rivers in this place has become more serpentine, in that more direct. And then, besides, some writers begin their measurements at one place, and some at another, and so proceed in different directions; and hence the result is, that no two accounts agree.
