The age of Pericles was the happiest and most glorious time in the history of Athens. Aeschylus, who had fought in the Persian wars, inaugurated Greek tragedy; one of his tragedies, the Persae, departing from the custom of choosing Homeric subjects, deals with the defeat of Darius. He was quickly followed by Sophocles, and Sophocles by Euripides, who, however, extends into the dark days of the Peloponnesian War that followed the fall and death of Pericles, and reflects in his plays the scepticism of the later period.
