⁵ sn On the Syrtis. The Syrtis was the name of two gulfs on the North African coast (modern Libya), feared greatly by sailors because of their shifting sandbars and treacherous shallows. The Syrtis here is the so-called Great Syrtis, toward Cyrenaica. It had a horrible reputation as a sailors’ graveyard (Pliny, Natural History 5.26). Josephus (J. W. 2.16.4 [2.381]) says the name alone struck terror in those who heard it. It was near the famous Scylla and Charybdis mentioned in Homer’s Odyssey.
