Many of us Persians know this well, and are here serving only under the bond of necessity.

' " This (observes Herodotus) I heard myself from the Orchome- nian Thersander, who told me farther that he mentioned the fact to several persons about him, even before the battle of Plataea." It is certainly one of the most curious revelations in the whole history ; not merely as it brings forward the historian in his own personality, communicating with a personal friend of the Theban leaders, and thus provided with good means of information as to the general events of the campaign, — but also as it discloses to us, on testimony not to be suspected, the real temper of the native Persians, and even of the chief men among them.
