Strategically important narrow pass (saltus) above Tarracina (in Latium) between the mountain range and a steep headland above the sea (Liv. 7,39,7; 22,15,11). The Romans were defeated there in 315 BC by the Samnites (Liv. 9,23,4; Diod. Sic. 19,72). From 312 onwards the steep via Appia led over it. Trajan had 128 feet of the height - measured from the base of the cliff - chopped off and the road built in the plain along the sea; modern Piscomontano.
