It became a Roman municipium; part of a copy of the Lex Iulia Municipalis of 46 BC (engraved on the back of two bronze tablets, on the front of which is a Greek inscription of the 3rd century BC defining the boundaries of lands belonging to various temples), which was found between Heraclea and Metapontum, is of the highest importance for our knowledge of that law. It was still a place of some importance under the empire; a branch road from Venusia joined the coast road here. The circumstances of its destruction and abandonment are unknown.
