Lives of the Sophists, written between 231 and 237 AD, is a semi-biographical history of the Greek sophists.
The biographical notices, the author avers, are condensed from the Onomatologion or Pinax of Hesychius of Miletus; other sources include the excerpts of Constantine Porphyrogenitus, the chronicle of Georgius Monachus, the biographies of Diogenes Laertius and the works of Athenaeus and Philostratus.
He published also notes on Stobaeus, Euripides, Athenaeus and the Iliaca of John Tzetzes; translations of Aelian (History of Animals); many of the Greek romances (Philostratus); poetical versions of much of the Greek Anthology; miscellaneous essays on classical subjects; and some very successful school books.
