The problem perpetually working in the minds of the Thebans was how they were to compass the headship of Hellas; and they persuaded themselves that, if they sent an embassy to the King of Persia, they could not but gain some advantage by his help. Accordingly they did not delay, but called together the allies, on the plea that Euthycles the Lacedaemonian was already at the Persian court. The commissioners sent up were, on the part of the Thebans, Pelopidas; (37) on the part of the Arcadians, Antiochus, the pancratiast; and on that of the Eleians, Archidamus. There was also an Argive in attendance. The Athenians on their side, getting wind of the matter, sent up two commissioners, Timagoras and Leon. (37) See Plut. "Pelop." 30 (Clough, vol. ii. p. 230). For the date see Grote, "H. G." x. 365, 379; Curtius, "H. G." iv. 460. When they arrived at the Persian court the influence of Pelopidas was preponderant with the Persian. He could point out that, besides the fact that the Thebans alone among all the Hellenes had fought on the king's side at Plataeae, (38) they had never subsequently engaged in military service against the Persians; nay, the very ground of Lacedaemonian hostility to them was that they had refused to march against the Persian king with Agesilaus, (39) and would not even suffer him to sacrifice to Artemis at Aulis (where Agamemnon sacrificed before he set sail for Asia and captured Troy). In addition, there were two things which contributed to raise the prestige of Thebes, and redounded to the honour of Pelopidas. These were the victory of the Thebans at Leuctra, and the indisputable fact that they had invaded and laid waste the territory of Laconia. Pelopidas went on to point out that the Argives and Arcadians had lately been defeated in battle by the Lacedaemonians, when his own countrymen were not there to assist. The Athenian Timagoras supported all these statements of the Theban by independent testimony, and stood second in honour after Pelopidas. (38) See Thuc. iii. 58, 59, 60. (39) See above, "Hell."
