the author of a famous work on military tactics, called Στρατηγικός Αδρός, is supposed to have lived about the middle of the first century after Christ, but nothing is known of his personal history. Subsequent Greek and Roman writers on military affairs made Onosander their text-book; and numerous generals, both in ancient and modern times, have expressed their obligations to him. His work was published first in Latin by Saguntinus, Rome, 1494; again in Latin by Camerarius in 1595; in French by Charrier, Paris, 1546; in Italian by Cotta, Venice, 1546; in English by Whytehorne, London, 1563; in Greek (for the first time) and Latin by Rigaltius, Paris, 1599. The best edition is that of Schwebel, Nürnberg, 1761, which ONTARIO contains the French version of Zur-Lauben, and notes from the MSS. of Jos. Scaliger and Is. Vossius. Onosander was a Platonist, and wrote a commentary on the Republic of his master, which is now lost.
