or TIMAGE'NIDES (Τιμαγενίδας, Τιμαγενίδης), a Theban, son of Herpys, was one of the principal adherents of the Persian cause in the invasion of Xerxes. Shortly before the battle of Plataea, Timagenides advised Mardonius to occupy the passes of Cithaeron, and so to intercept the re-inforcements and supplies which were coming in through them to the enemy. The advice was taken, and the Persians succeeded in cutting off a convoy of provisions with 500 beasts of burden. After their victory at Plataea the Greeks advanced against Thebes, and demanded that the chief traitors to the national cause, Timagenides among the number, should be given up to them. The Thebans at first refused in spite of the ravages which their land suffered, but at length they consented at the instigation of Timagenides himself. It appears that the culprits expected to be brought to an open trial, at which they hoped to have recourse effectually to the expedient of bribery. To prevent this, however, Pausanias carried them off to Corinth, and there put them to death without any judicial ceremony. (Hdt. 9.38, 86_88; Paus. 7.10.)
