In this portion of Southern Spain deposits of cupreous iron pyrites, consisting of a series of lenticular masses of ore, having a general direction a little north of east and south of west, extend from Aznalcollar, near Seville, in the east, for a distance of more than seventy miles westward to within the Portuguese frontier. At Bio Tinto the deposits of this mineral are very extensive, and consist of a compact and intimate admixture of iron pyrites with a little copper pyrites, through which strings of the latter mineral sometimes ramify. Although these mines appear to have been worked, and the copper smelted upon the spot, from time immemorial, it is evident from the vast heaps of furnace-slags, and from the extent of the various other remains in which coins and inscriptions of the reigns of the Emperors from Nerva to Honorius have been discovered, that their great development under the Bomans took place during the first four centuries of the Christian era.
