1. An Olynthian, who, together with Euthycrates, is accused by Demosthenes of having betrayed his country to Philip of Macedon, by whom he had been bribed.
It appears that he was appointed to command the cavalry belonging to Olynthus in B. C. 348, when Philip directed his arms against the city; but availed himself of the opportunity to betray into the hands of the king a body of 500 horse, which were made prisoners without resistance.
After the fall of Olynthus, Philip naturally treated with neglect the traitors, of whom he had no longer any need; but it seems to have been erroneously inferred from an expression of Demosthenes, that they were positively ill treated, or even put to death, by that monarch.
An anecdote related by Plutarch shows that Lasthenes was resident at the court of Philip at a subsequent period. (Dem. de Chers.
