Olim autem hanc navigationem Gaditanis percognitam fuisse, multa argumento sunt. Caio Caesare Augusti filio in Arabico sinu res gerente signa navium ex Hispaniensibus naufragiis agnita. Et quod Caelius Antipater tradidit, vidisse se qui ex Hispania in Aethiopiam commercii gratia navigasset. Etiam Arabibus, si verum est, quod Cornelius Nepos testatus est, Eudoxum quendam sua aetate cum Lathyrum Regem Alexandriae fugeret, Arabico sinu egressum Gades usque pervectum. Poenos autem, qui re maritima plurimum valuerunt, eum Oceanum non ignorasse longe clarissimum est, cum Hanno Carthaginis potentia florente circumvectus a Gadibus ad finem Arabiae, praeternavigato scilicet promontorio quod nunc Bonae Spei dicitur, (vetus videtur nomen Hesperion ceras fuisse) omne id iter, situmque litoris et insularum scripto complexus sit, testatusque ad ultimum non mare sibi, sed commeatum defuisse. Ab Arabico autem sinu ad Indiam, Indicique Oceani insulas, et auream usque Chersonesum, quam esse Iapanem credunt plerique, etiam re Romana florente navigari solitum, iter a Plinio descriptum,[104a] legationes ab Indis ad - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - is not a single person in the world who does not know that a ship sailing through the sea leaves behind it no more legal right than it does a track. And as for the assumption of the Portuguese that no one has sailed that ocean before themselves, that is anything but true. For a great part of that sea near Morocco, which is in dispute, had already been navigated long before, and the sea as far east as the Arabian gulf has been made famous by the victories of Alexander the Great, as both Pliny and Mela tell us.[103] There is also much to substantiate the belief that the inhabitants of Cadiz were well acquainted long ago with this route, because when Gaius Caesar,* the son of Augustus, held command in the Arabian gulf, pieces were found of shipwrecks recognized as Spanish. Caelius Antipater also has told us in his writings that he himself saw a Spaniard who had sailed from Spain to Ethiopia on a commercial voyage. Also the Arabians knew those seas, if the testimony of Cornelius Nepos is to be believed, because he says that in his own day a certain Eudoxus, fleeing from Lathyrus, king of Alexandria, sailed from the Arabian gulf and finally reached Cadiz. However, by far the most famous example is that of the Carthaginians. Those most famous mariners were well acquainted with that sea, because Hanno, when Carthage was at the height of her power, sailing from Cadiz to the farthest confines of Arabia, and doubling the promontory now known as the Cape of Good Hope (the ancient name seems to have been Hesperion Ceras), described in a book the entire route he had taken, the appearance of the coasts, and the location of the islands, declaring that at the farthest point he reached the sea had not yet given out but his provisions had.
