Onasander

Onasander or Onosander ( ''Onesandros'' or Ὀνόσανδρος ''Onosandros''; fl. 1st century AD) was a Greek philosopher. He was the author of a commentary on the ''Republic'' of Plato, which is lost; as well as of the ''Strategikos'' () - a short but comprehensive work on the duties of a general, which was dedicated to Quintus Veranius. The ''Strategikos'' was the main source used for the military writings of emperors Maurice and Leo VI, as well as of Maurice of Saxony, who consulted it in a French translation and expressed a high opinion of it.
