 Antiochus is the only writer who mentions the share taken by the Thurians in its original foundation.Pliny erroneously regards Heraclea as identical with Siris, to which it had succeeded; and it was perhaps a similar misconception that led Livy, by a strange anachronism, to include Heraclea among the cities of Magna Graecia where Pythagoras established his institutions.The new colony appears to have risen rapidly to power and prosperity, protected by the fostering care of the Tarentines, who were at one time engaged in war with the Messapians for its defence.
