The Istir and the Pontus of the Adriatic Sea

Even the Mantoris who dwell near the Adriatic ascend this crest, they describe as it appears the ships sailing into the Pontus. And we have seen a proof, not only in the present times, but also more fully in antiquity, that the waters there are not inevigable. For they say that Jason sailed into thePontus by the dark rocks while he sailed out of it by the Istir. In Torentum at certain times people offer sacrifices to the shades of the Etridai, Tudidai, Ayakadai, and Lyertia Dai.
