Such recognition was not indeed in itself either any loss to Amyntas, or any gain to Athens; for Amphipolis, though bordering on his kingdom, had never belonged to him, nor had he any power of transferring it. Originally an Athenian colony,[530] next taken from Athens in 424-423 B.C. by Brasidas, through the improvidence of the Athenian officers Euklês and Thucydides, then recolonized under Lacedæmonian auspices,—it had ever since remained an independent city; though Sparta had covenanted to restore it by the peace of Nikias (421 B.C.), but had never performed her covenant. Its unparalleled situation, near to both the bridge and mouth of the Strymon, in the midst of a fertile territory, within reach of the mining district of Pangæus,—rendered it a tempting prize; and the right of Athens to it was indisputable; so far as original colonization before the capture by Brasidas, and formal treaty of cession by Sparta after the capture, could confer a right. But this treaty, not fulfilled at the time, was now fifty years old. The repugnance of the Amphipolitan population, which had originally prevented its fulfilment, was strengthened by all the sanction of a long prescription; while the tomb and chapel of Brasidas their second founder, consecrated in the agora, served as an imperishable admonition to repel all pretensions on the part of Athens. Such pretensions, whatever might be the right, were deplorably impolitic unless Athens was prepared to back them by strenuous efforts of men and money; from which we shall find her shrinking now as she had done (under the unwise advice of Nikias) in 421 B.C., and the years immediately succeeding. In fact, the large renovated pretensions of Athens both to Amphipolis and to other places on the Macedonian and Chalkidic coast, combined with her languor and inertness in military action,—will be found henceforward among the greatest mischiefs to the general cause of Hellenic independence, and among the most effective helps to the well-conducted aggressions of Philip of Macedon. [530] The pretensions advanced by Philip of Macedon (in his Epistola ad Athenienses, ap. Demosthen. p. 164), that Amphipolis or its locality originally belonged to his ancestor Alexander son of Amyntas, as having expelled the Persians from it,—are unfounded, and contradicted by Thucydides. At least, if (which is barely possible) Alexander ever did acquire the spot, he must have lost it afterwards; for it was occupied by the Edonian Thracians, both in 465 B.C., when Athens made her first unsuccessful attempt to plant a colony there,—and in 437 B.C., when she tried again with better success under Agnon, and established Amphipolis (Thucyd. iv, 102).
