 fortress of Pucinum, famous for its wines, the Gulf of Tergeste , and the colony of that name, thirty-three miles from Aquileia. Six miles beyond this place lies the river Formio, 189 miles distant from Ravenna, the ancient boundary of enlarged Italy, and now the frontier of Istria. That this region takes its name from the river Ister which flows from the Danube, also called the Ister, into the Adriatic opposite the mouth of the Padus, and that the sea which lies between them is rendered fresh by their waters running from opposite directions, has been erroneously asserted by many, and among them by Nepos even, who dwelt upon the banks of the Padus. For it is the fact that no river which runs from the Danube discharges itself into the Adriatic. They have been misled, I think, by the circumstance that the ship Argo came down some river into the Adriatic sea, not far from Tergeste; but what river that was is now unknown. The most careful writers say that the ship was carried across the Alps on men's shoulders, having passed along the Ister, then along the Savus, and so from Nauportus, which place, lying between Æmona and the Alps, from that circumstance derives its name.

5 He alludes to an old tradition that the Argonauts sailed into the Ister or Danube, and then into the Save, till they came to the spot where the modern town of Upper Laybach stands, and that here they built Nauportus, after which they carried their ship across the mountains on men's shoulders into the Adriatic. He intends to suggest therefore that the place had its name from the Greek ναςῡ "a ship" and πορθμὁς "a passage."
