What is "agathyrnum"

Agathyrnum or Agathyrna ( Ancient Greek: ), was an ancient city on the north coast of Sicily between Tyndaris and Calacte. It was supposed to have derived its name from Agathyrnus, a son of Aeolus, who is said to have settled in this part of Sicily. But though it may be inferred from this story that it was an ancient city, and probably of Sicelian origin, we find no mention of it in history until after Sicily became a Roman province. During the Second Punic War it became the headquarters of a band of robbers and freebooters, who extended their ravages over the neighboring country, but were reduced by the consul Laevinus in 210 BCE, who transported 4000 of them to Rhegium. It very probably was deprived on this occasion of the municipal rights conceded to most of the Sicilian towns, which may account for our finding no notice of it in Cicero, though it is mentioned by Strabo among the few cities still subsisting on the north coast of Sicily, as well as afterwards by Pliny, Ptolemy and the Itineraries.
