Meanwhile the attention of Athens was called off from these combined enemies by a more menacing cloud, which threatened to burst upon her from the side of Sparta. Kleomenês and his countrymen, full of resentment at the late inglorious desertion of Eleusis, were yet more incensed by the discovery, which appears to have been then recently made, that the injunctions of the Delphian priestess for the expulsion of Hippias from Athens had been fraudulently procured.[305] Moreover, Kleomenês, when shut up in the acropolis of Athens with Isagoras, had found there various prophecies previously treasured up by the Peisistratids, many of which foreshadowed events highly disastrous to Sparta. And while the recent brilliant manifestations of courage, and repeated victories, on the part of Athens, seemed to indicate that such prophecies might perhaps be realized,—Sparta had to reproach herself, that, from the foolish and mischievous conduct of Kleomenês, she had undone the effect of her previous aid against the Peisistratids, and thus lost that return of gratitude which the Athenians would otherwise have testified. Under such impressions, the Spartan authorities took the remarkable step of sending for Hippias from his residence at Sigeium to Peloponnesus, and of summoning deputies from all their allies to meet him at Sparta. [305] Herodot. v, 90. The convocation thus summoned deserves notice as the commencement of a new era in Grecian politics. The previous expedition of Kleomenês against Attica presents to us the first known example of Spartan headship passing from theory into act: that expedition miscarried because the allies, though willing to follow, would not follow blindly, nor be made the instruments of executing purposes repugnant to their feelings. Sparta had now learned the necessity, in order to insure their hearty concurrence, of letting them know what she contemplated, so as to ascertain at least that she had no decided opposition to apprehend. Here, then, is the third stage in the spontaneous movement of Greece towards a systematic conjunction, however imperfect, of its many autonomous units. First we have Spartan headship suggested in theory, from a concourse of circumstances which attract to her the admiration of all Greece,—power, unrivalled training, undisturbed antiquity, etc.: next, the theory passes into act, yet rude and shapeless: lastly, the act becomes clothed with formalities, and preceded by discussion and determination. The first convocation of the allies at Sparta, for the purpose of having a common object submitted to their consideration, may well be regarded as an important event in Grecian political history. The proceedings at the convocation are no less important, as an indication of the way in which the Greeks of that day felt and acted, and must be borne in mind as a contrast with times hereafter to be described.
