HYPEREIDES (c. B.c.), one of the ten Attic ora tors, was the son of Glaucippus, of the deme of Collytus. Having studied under Isocrates, in 36o he prosecuted Autocles, a general charged with treason in Thrace (frags. 55-65, Blass). At the time of the Social War (3 5 5) he accused Aristophon, then one of the most influential men at Athens, of malpractices (f rags. Blass), and impeached Philocrates (343) for high treason. From the peace of 346 to 324 Hypereides supported Demosthenes in the struggle against Macedon ; but in the affair of Harpalus he was one of the ten public prosecutors of Demosthenes, and on the exile of Demosthenes he became the head of the patriotic party (324). He was the chief promoter of the Lamian war against Antipater and Craterus, and after the defeat at Crannon (322), Hypereides and the other orators, whose surrender was demanded by Antipater, were condemned to death. Hypereides fled to Aegina, but Antipater's emissaries dragged him from the temple of Aeacus, where he had taken refuge, and put him to death ; according to others, he was taken before Antipater at Athens or Cleonae. His body was afterwards removed to Athens.
Hypereides was an ardent pursuer of "the beautiful" ; his temper was easy-going and humorous. In his development of the periodic sentence he followed Isocrates, but the essential tenden cies of his style are those of Lysias, whom he surpassed, however, in the richness of his vocabulary and in the variety of his powers. His diction was plain and forcible, and his composition simple. Jebb sums up the criticism of pseudo-Longinus (De sublimitate, 34) in the phrase—"Hypereides was the Sheridan of Athens." Most of what we possess of Hypereides's speeches was dis covered in the second half of the 19th century, and edited by Sir Frederick Kenyon (1893) .
