The first extensive works of literature in Attic are the plays of dramatists Aeschylus, Sophocles, Euripides, and Aristophanes dating from the fifth century BC. The military exploits of the Athenians led to some universally read and admired history, as found in the works of Thucydides and Xenophon. Slightly less known because they are more technical and legal are the orations by Antiphon, Demosthenes, Lysias, Isocrates, and many others. The Attic Greek of philosophers Plato (427–347 BC) and his student Aristotle (384–322 BC) dates to the period of transition between Classical Attic and Koine.
