2. The son of Theognis, of Marathon, a distinguished comic actor at Athens, and a contemporary of Demosthenes, is said to have given instructions to the young orator in the art of giving full effect to his speeches by appropriate action. (Plut. Dem. 7.) The same orator relates an honourable anecdote of him, that having once been at a festival given by Philip king of Macedon, after the capture of Olynthus (B. C. 347), when the king was making large presents to all the other artists, Satyrus begged, as his reward, the liberation of two of the Olynthian captives, daughters of an old friend of his, to whom he afterwards gave marriage portions at his own cost. (Dem. de fals. Leg. pp. 401, 402; Diod. 16.55.) He is also mentioned incidentally by Plutarch (De se ips. c. inv. laud. p. 545f.).
Athenaeus (xiii. p. 591e.) quotes a statement respecting Phryne from the Pamphila of " Satyrus, the actor, of Olynthus," from which it would seem that Satyrus not only acted comedies, but also wrote some. Either Athenaeus may have called him an Olynthian carelessly, from the scene of the anecdote in Demosthenes being at Olynthus, or he may have settled at Olynthus.
