Their embassy reached Sparta about B.C. 383, when the Spartans, having broken up the city of Mantinea into villages, and coërced Phlius, were in the full swing of power over Peloponnesus,—and when they had also dissolved the Bœotian federation, placing harmosts in Platæa and Thespiæ as checks upon any movement of Thebes. The Akanthian Kleigenês, addressing himself to the Assembly of Spartans and their allies, drew an alarming picture of the recent growth and prospective tendencies of Olynthus, invoking the interference of Sparta against that city. The Olynthian confederacy (he said) already comprised many cities, small and great, Greek as well as Macedonian,—Amyntas having lost his kingdom. Its military power, even at present great, was growing every day.[124] The territory, comprising a large breadth of fertile corn-land, could sustain a numerous population. Wood for ship-building was close at hand, while the numerous harbors of the confederate cities ensured a thriving trade as well as a steady revenue from custom-duties. The neighboring Thracian tribes would be easily kept in willing dependence, and would thus augment the military force of Olynthus; even the gold mines of Mount Pangæus would speedily come within her assured reach. “All that I now tell you (such was the substance of his speech) is matter of public talk among the Olynthian people, who are full of hope and confidence. How can you Spartans, who are taking anxious pains to prevent the union of the Bœotian cities,[125] permit the aggregation of so much more formidable a power, both by land and by sea, as this of Olynthus? Envoys have already been sent thither from Athens and Thebes,—and the Olynthians have decreed to send an embassy in return for contracting alliance with those cities; hence, your enemies will derive a large additional force. We of Akanthus and Apollonia, having declined the proposition to join the confederacy voluntarily, have received notice that, if we persist, they will constrain us. Now we are anxious to retain our paternal laws and customs, continuing as a city by ourselves.[126] But if we cannot obtain aid from you, we shall be under the necessity of joining them,—as several other cities have already done, from not daring to refuse; cities, who would have sent envoys along with us, had they not been afraid of offending the Olynthians. These cities, if you interfere forthwith, and with a powerful force, will now revolt from the new confederacy. But if you postpone your interference, and allow time for the confederacy to work, their sentiments will soon alter. They will come to be knit together in attached unity, by the co-burgership, the intermarriage, and the reciprocity of landed possessions, which have already been enacted prospectively. All of them will become convinced that they have a common interest both in belonging to, and in strengthening the confederacy,—just as the Arcadians, when they follow you, Spartans,
