The town is the medieval successor of the ancient Arpi, 3 m.
He was the reputed founder of Argyrippa (Arpi) and other Italian cities (Aeneid, xi.
283) speaks of Canusium and Arpi as having been, to judge from the extent of their walls, the greatest towns in the plain of Apulia, but as having shrunk considerably in his day.
As a protection against the Samnites Arpi became an ally of Rome, and remained faithful until after the battle of Cannae, but Fabius captured it in 213 B.C., and it never recovered its former importance.
This marks the site of the ancient Sipontum, the harbour of Arpi, which became a Roman colony in 194 B.C., and was not deserted in favour of Manfredonia until the r3th century, having become unhealthy owing to the stagnation of the water in the lagoons.
