Lesbonax, of Mytilene, Greek sophist and rhetorician, flourished in the time of Caesar Augustus. According to Photius I of Constantinople he was the author of sixteen political speeches, of which two are extant, a hortatory speech after the style of Thucydides, and a speech on the Corinthian War. In the first he exhorts the Athenians against the Spartans, in the second (the title of which is misleading) against the Thebans (edition by F. Kiehr, Lesbonactis sophistae quae supersunt (Leipzig 1906). Some erotic letters are also attributed to him. His son Potamo was also a notable rhetorician.
The Lesbonax described in the Suda as the author of a large number of philosophical works is probably of much earlier date; on the other hand, the author of a small treatise on grammatical figures (ed. Rudolf Miller, Leipzig, 1900), is probably later.
A Greek rhetorician who lived early in the first century of our era. He composed political declamations on imaginary topics. Two of these have come down to us, exhorting the Athenians in the Peloponnesian War to be bold in battle against the Thebans and the Spartans. They have been separately edited by Orelli (Leipzig, 1820).
A Greek grammarian of uncertain date, though later than the preceding. There exists a work of his on figures of grammar (Περὶ Σχημάτων). See R. Müller, De Lesbonacte Grammatico (1890).
