It appears that the Bœotians from the neighborhood of the Asôpus were necessary as guides for this road. Perhaps even the territory of Orôpus was at this time still a part of Bœotia: we do not certainly know at what period it was first conquered by the Athenians. The combats between Athenians and Bœotians will be found to take place most frequently in this southeastern region of Bœotia,—Tanagra, Œnophyta, Delium, etc. [316] Herodot. ix, 15. Mardonius found himself thus with his numerous army, in a plain favorable for cavalry; with a camp more or less defensible,—the fortified city of Thebes[317] in his rear,—and a considerable stock of provisions as well as a friendly region behind him from whence to draw more. Few among his army, however, were either hearty in the cause or confident of success:[318] even the native Persians had been disheartened by the flight of the monarch the year before, and were full of melancholy auguries. A splendid banquet to which the Theban leader Attagînus invited Mardonius, along with fifty Persians and fifty Theban or Bœotian guests, exhibited proofs of this depressed feeling, which were afterwards recounted to Herodotus himself by one of the guests present,—an Orchomenian citizen of note named Thersander. The banquet being so arranged as that each couch was occupied by one Persian and one Theban, this man was accosted by his Persian neighbor in Greek, who inquired to what city he belonged, and, upon learning that he was an Orchomenian,[319] continued thus: “Since thou hast now partaken with me in the same table and cup, I desire to leave with thee some memorial of my convictions: the rather, in order that thou mayst be thyself forewarned so as to take the best counsel for thine own safety. Seest thou these Persians here feasting, and the army which we left yonder encamped near the river? Yet a little while, and out of all these thou shalt behold but few surviving.” Thersander listened to these words with astonishment, spoken as they were with strong emotion and a flood of tears, and replied: “Surely, thou art bound to reveal this to Mardonius, and to his confidential advisers:” but the Persian rejoined: “My friend, man cannot avert that which God hath decreed to come: no one will believe the revelation, sure though it be. Many of us Persians know this well, and are here serving only under the bond of necessity. And truly this is the most hateful of all human sufferings,—to be full of knowledge, and at the same time to have no power over any result.”[320] “This (observes Herodotus) I heard myself from the Orchomenian Thersander, who told me farther that he mentioned the fact to several persons about him, even before the battle of Platæa.” 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
