Archaeological site of Compsa

Compsa was an ancient city of the Hirpini, near the sources of the Aufidus, on the boundary of Lucania and not far from that of Apulia, on a ridge 609 m above sea level. It was betrayed to Hannibal in 216 BC after the defeat of Cannae, but recaptured two years later. It was probably occupied by Sulla in 89 BC, and was the scene of the death of Titus Annius Milo in 48 BC.

Most modern sources, for example Hülsen in Pauly-Wissowa's Realencyclopädie, refer Caesar's Commentarii de Bello Civili and Pliny's Naturalis Historiæ to this place, supposing the ancient manuscripts to be corrupt. Thus the usual identification of the site of Milo's death with Cassano allo Ionio on the Gulf of Taranto must be incorrect.
