 But two years afterwards (413 BC) the Athenian party had regained the ascendency; and when Demosthenes and Eurymedon touched at Thurii, the citizens afforded them every assistance, and even furnished an auxiliary force of 700 hoplites and 300 dartmen.From this time we hear nothing of Thurii for a period of more than 20 years, though there is reason to believe that this was just the time of its greatest prosperity.In 390 BC we find that its territory was already beginning to suffer from the incursions of the Lucanians, a new and formidable enemy, for protection against whom all the cities of Magna Graecia had entered into a defensive league.
