or DATUS, in Ancient Geography, a town of Thrace, situated between Neapolis and the river Nestus: A colony of Thracians, according to Eustathius; who places it on the sea coast, near the Strymon, in a rich and fruitful soil, famous for ship-building and mines of gold; hence the proverb Δαλος Αγαθος, denoting prosperity and plenty (Strabo.) Apian describes it as seated on a steep eminence, the whole of which it covered. It was taken by Philip of Macedon, who changed its name to Philippi, being originally called Crenides on account of its springs. It was afterwards famous for the defeat of Brutus and Cassius, by Augustus and Antony.
