Leo

, a native of Byzantium, who flourished 350 years before the christian era. His philosophical and political talents endeared him to his countrymen, and he was always sent upon every important occasion as amba ador to Athens, or to the court of Philip king of Macedonia. This monarch, well acquainted with the abilities of Leo, was sensible that his views and claims to Byzantium would never succeed while it was protected by the vigilance of such a patriotic citizen. To remove him he had recourse to artifice and perfidy. A letter was forged, in which Leo made solemn promises of betraying his country to the king of Macedonia for money. This was no sooner known than the people ran enraged to the house of Leo, and the philosopher, to avoid their fury, and without attempting his justification, strangled himself. He had written some treatises upon physic, and also the history of his country, and the wars of Philip in seven books, which have been lost.
