(5) The Bradano, which rises near Venosa, almost at the foot of Monte Volture, flows towards the south-east into the Gulf of Taranto, as do the Basento, the Agri and the Sinni, all of which descend from the central chain of the Apennines south of Potenza.
Above sea-level on an isolated hill above the Basento (anc. Casuentus), it is much exposed to winds and has a far more northerly climate than its position (40° 40' N.) implies, and is indeed one of the coldest places in Italy (mean temp. Jan 37.8°, July 70.9°, for whole year 53° F.).
It is traversed by five rivers, the Bradano, Basento, Cavone or Salandrella, Agri and Sinni.
