The reëstablishment of Mantinea was probably completed during the autumn and winter of B.C. 371-370. Such coalescence of villages into a town, coupled with the predominance of feelings hostile to Sparta, appears to have suggested the idea of a larger political union among all who bore the Arcadian name. As yet, no such union had ever existed; the fractions of the Arcadian name had nothing in common, apart from other Greeks, except many legendary and religious sympathies, with a belief in the same heroic lineage and indigenous antiquity.[439] But now the idea and aspiration, espoused with peculiar ardor by a leading Mantinean named Lykomedes, spread itself rapidly over the country, to form a “commune Arcadum,” or central Arcadian authority, composed in certain proportions out of all the sections now autonomous,—and invested with peremptory power of determining by the vote of its majority. Such central power, however, was not intended to absorb or set aside the separate governments, but only to be exercised for certain definite purposes; in maintaining unanimity at home, together with concurrent, independent action, as to foreign states.[440] This plan of Pan-Arcadian federation was warmly promoted by the Mantineans, who looked to it as a protection to themselves in case the Spartan power should revive; as well as by the Thebans and Argeians, from whom aid was expected in case of need. It found great favor in most parts of Arcadia, especially in the small districts bordering on Laconia, which stood most in need of union to protect themselves against the Spartans,—the Mænalians, Parrhasians, Eutresians, Ægytes,[441] etc. But the jealousies among the more considerable cities made some of them adverse to any scheme emanating from Mantinea. Among these unfriendly opponents were Heræa, on the west of Arcadia bordering on Elis,—Orchomenus,[442] conterminous with Mantinea to the north—and Tegea, conterminous to the south. The hold of the Spartans on Arcadia had been always maintained chiefly through Orchomenus and Tegea. The former was the place where they deposited their hostages taken from other suspected towns; the latter was ruled by Stasippus and an oligarchy devoted to their interests.[443] [439] It seems, however, doubtful whether there were not some common Arcadian coins struck, even before the battle of Leuktra. Some such are extant; but they are referred by K. O. Müller, as well as by M. Boeckh (Metrologisch. Untersuchungen, p. 92) to a later date subsequent to the foundation of Megalopolis.
