Augustum, ad Claudium etiam ex Taprobane insula, deinde gesta Traiani et tabulae Ptolemaei satis ostendunt. Iam suo tempore Strabo[105a] Alexandrinorum mercatorum classem ex Arabico sinu, ut Aethiopiae ultima, ita et Indiae, petiisse testatur, cum olim paucis navibus id auderetur. Inde magna populo Romano vectigalia; addit Plinius[106a] impositis sagittariorum cohortibus piratarum metu navigatum; solamque Indiam quingenties sestertium, si Arabiam addas et Seres, millies annis omnibus Romano Imperio ademisse; et merces centuplicato venditas.
Et haec quidem vetera satis arguunt primos non fuisse Lusitanos. In singulis autem sui partibus Oceanus ille et tunc cum eum Lusitani ingressi sunt, et numquam non cognitus fuit. Mauri enim, Aethiopes, Arabes, Persae, Indi, eam maris partem cuius ipsi accolae sunt, nescire neutiquam potuerunt.
Mentiuntur ergo qui se mare illud invenisse iactant.
Quid igitur, dicet aliquis, parumne videtur, quod Lusitani intermissam multis forte saeculis navigationem primi repararunt, et, quod negari non potest, Europaeis gentibus ignotam ostenderunt, magno suo labore, sumptu, periculo?
from the Indies to Augustus, and those from Ceylon to the emperor Claudius, and finally the accounts of the deeds of Trajan, and the writings of Ptolemaeus, all make it quite clear that in the days of Rome’s greatest splendor voyages were made regularly from the Arabian gulf to India, to the islands of the Indian ocean, and even so far as to the golden Chersonesus, which many people think was Japan. Strabo says[105] that in his own time a fleet of Alexandrian merchantmen set sail from the Arabian gulf for the distant lands of Ethiopia and India, although few ships had ever before attempted that voyage. The Roman people had a large revenue from the East. Pliny says[106] that cohorts of archers were carried on the boats engaged in trade as protection against pirates; he states also that every year 500,000 sesterces* were taken out of the Roman empire by India alone, or 1,000,000 sesterces if you add Arabia and China; further, that merchandise brought from the East sold for one hundred times its original cost.
* [A Roman sestertius was about four cents.]
These examples cited from ancient times are sufficient proof that the Portuguese were not the first in that part of the world. Long before they ever came, every single part of that ocean had been long since explored. For how possibly could the Moors, the Ethiopians, the Arabians, the Persians, the peoples of India, have remained in ignorance of that part of the sea adjacent to their coasts!
Therefore they lie, who today boast that they discovered that sea.
Well then, some one will say, does it seem to be a matter of little moment that the Portuguese were the first to restore a navigation interrupted perhaps for many centuries, and unknown—as cannot be denied—at least to the nations of Europe, at great labor and cost and danger to themselves?
