XXVII. On his return from his campaign against the Thebans, Agesilaus, while passing through Megara, was seized with violent pain in his sound leg, just as he was entering the town-hall in the Acropolis of that city. After this it became greatly swelled and full of blood, and seemed to be dangerously inflamed. A Syracusan physician opened a vein near the ankle, which relieved the pain, but the flow of blood was excessive, and could not be checked, so that he fainted away from weakness, and was in a very dangerous condition. At length the bleeding stopped, and he was conveyed home to Lacedæmon, but he remained ill, and unable to serve in the wars for a long time. During his illness many disasters befel the Spartans both by land and by sea. Of these, the most important was the defeat at Tegyra, where for the first time they were beaten in a fair fight by the Thebans. The Lacedæmonians were now eager to make peace with all the Greek cities, and ambassadors from all parts of Greece met at Sparta to arrange terms. Among them was Epameinondas, a man who was renowned for his culture and learning, but who had not hitherto given any proof of his great military genius. This man, perceiving that all the other ambassadors were sedulously paying their court to Agesilaus, assumed an independent attitude, and in a speech delivered before the congress declared that nothing kept the war alive except the unjust pretensions of Sparta, who gained strength from the sufferings of the other states, and that no peace could be durable unless such pretensions were laid aside, and Sparta reduced to the equality with the rest of the cities of Greece. XXVIII. Agesilaus, observing that all the representatives of the Greek states were filled with admiration at this language, and manifested strong sympathy with the speaker, enquired whether he thought it right and just that the cities of Bœotia[188] should be left independent. Epameinondas quickly and boldly enquired in answer, whether he thought it right to leave each of the towns in Laconia independent. At this Agesilaus leaped to his feet in a rage, and asked him to state clearly whether he meant to leave Bœotia independent. As Epameinondas in reply merely repeated his question, as to whether Agesilaus meant to leave Laconia independent, Agesilaus became furious, eagerly seized the opportunity to strike the name of Thebes out of the roll of cities with whom peace was being made, and declared war against it. He ratified a treaty of peace with the other Greek cities, and bade their representatives begone, with the remark, that such of their disputes as admitted of settlement must be arranged by peaceful negotiation, and such as could not must be decided by war; but that it was too much trouble for him to act as arbitrator between them in their manifold quarrels and disagreements.
