Plato, the comic poet, called the prince of the middle comedy, and of whose pieces some fragments remain, flourished about this time.

Also, Aristarchus, the tragic poet of Tegea, who composed 70 tragedies, one of which was translated into Latin verse by Ennius.

Herodotus of Halicarnassus, wrote a history of the Wars of the Greeks against the Persians from the age of Cyrus to the battle of Mycale, including an account of the most celebrated nations in the world. Besides this, he had written a history of Assyria and Arabia which is not extant. There is a life of Homer generally attributed to him, but doubtfully. B.C. 445.

Euripides, who lived at this time, wrote 75 or, as some say, 92 tragedies, of which only 19 are extant. He was the rival of Sophocles.

About the commencement of the Peloponnesian war, flourished many celebrated authors, among whom was Aristophanes. He wrote 54 comedies, of which only 11 are extant.

Also, Cratinus and Eupolis, who with Aristophanes, are mentioned by Horace—they were celebrated for their comic writings. B.C. 431.

Also, the mathematician and astrologer, Meton, who, in a book called Enneadecaterides, endeavored to adjust the course of the sun and moon, and maintained that the solar and lunar years could regularly begin from the same point in the heavens. This is called the Metonic cycle.

Thucydides flourished at this time. He wrote a history of the important events which happened during his command. This history is continued only to the 21st year of the war. It has been divided into eight books—the last of which is supposed to have been written by his daughters. It is imperfect.

Also Hippocrates;—few of his writings remain.

Lysias, the orator, wrote, according to Plutarch, no less than 425 orations—of these 34 are extant. B.C. 404.
