The Classical Greek Orators Collection includes speeches and letters from 11 of the most influential orators of the fourth and fifth centuries BC. Since the days of Homer, the art of public speaking was of great value in Greece. Eventually, oratory became a focal subject in Greek education, thanks in large part to the lasting influences of orators from the classical era. This 30-volume collection contains the works of the most influential classical orators, known later as the Alexandrian “Canon of 10”: Aeschines, Antiphon, Andocides, Demosthenes, Dinarchus, Hyperides, Isaeus, Isocrates, Lycurgus, and Lysias.
