That during the preceding century, the Amphiktyonic assembly had meddled rarely, and had never meddled to any important purpose, in the political affairs of Greece—is proved by the fact that it is not once mentioned either in the history of Thucydides, or in the Hellenica of Xenophon. But after the humiliation of Sparta at Leuktra, this great religious convocation of the Hellenic world, after long torpor, began to meet for the despatch of business. Unfortunately its manifestations of activity were for the most part abusive and mischievous. Probably not long after the battle of Leuktra, though we do not know the precise year—the Thebans exhibited before the Amphiktyons an accusation against Sparta, for having treacherously seized the Kadmeia (the citadel of Thebes) in a period of profound peace. Sentence of condemnation was pronounced against her,[510] together with a fine of five hundred talents, doubled after a certain interval of non-payment. The act here put in accusation was indisputably a gross political wrong; and a pretence, though a very slight pretence, for bringing political wrong under cognizance of the Amphiktyons, might be found in the tenor of the old oath taken by each included city.[511] Still, every one knew that for generations past, the assembly had taken no actual cognizance of political wrong; so that both trial and sentence were alike glaring departures from understood Grecian custom—proving only the humiliation of Sparta and the insolence of Thebes. The Spartans of course did not submit to pay, nor were there any means of enforcement against them. No practical effect followed therefore, except (probably) the exclusion of Sparta from the Amphiktyonic assembly—as well as from the Delphian temple and the Pythian games. Indirectly, however, the example was most pernicious, as demonstrating that the authority of a Pan-hellenic convocation, venerable from its religious antiquity; could be abused to satisfy the political antipathies of a single leading state.
