Book 7
5.9
From the Liburni to the Ceraunian mountains is a distance of a little more than 2000 stadia. But Theopompus says, that it is six days’ sail from the farthest recess of the bay, but a journey of thirty days by land along the length of Ilyria. This appears to me an exaggeration, but he makes many incredible statements. Among other instances, he pretends that there is a subterraneous passage between the Adriatic and the Aegaean Seas, grounding his opinion on the discovery of Chian and Thasian pottery in the river Naron.Narenta. The two seas, he says, may be seen from some pretended mountain. He describes the Liburnian islands as occupying a position so extensive as to form a circle of 500 stadia. According to him, the Danube discharges itself by one of its mouths into the Adriatic.A common opinion among ancient geographers. See b. i. c. ii. § 39. Similar mistakes are to be found in Eratosthenes, which Polybius, when speaking of him and other writers, describes as having their origin in vulgar error.παρακούσματα λαοδογματικά
