The death of Hegesistratus, however, took place after the Plataean business. At the present he was by the Asopus, hired by Mardonius for no small wage, where he sacrificed and worked zealously, both for the hatred he bore the Lacedaemonians and for gain. When no favorable omens for battle could be won either by the Persians themselves or by the Greeks who were with them (for they too had a diviner of their own, Hippomachus of Leucas), and the Greeks kept flocking in and their army grew, Timagenides son of Herpys, a Theban, advised Mardonius to guard the outlet of the pass over Cithaeron, telling him that the Greeks were coming in daily and that he would thereby cut off many of them.
