Demosthenes

Demosthenes was the greatest Athenian orator of antiquity, famous for his Philippics warning Athens of the Macedonian threat under Philip II.

Demosthenes perfected Greek deliberative rhetoric and used it in service of Athenian democracy; his Philippics against Philip II of Macedon became the model of forceful political speech, and his name became synonymous with impassioned civic oratory.
