A great wave, successive waves, of invasion, sufficiently remote to have lost already all historic truth of detail, had left them--these Helots, and the Perioeci, in the country round about--thus to serve among their own kinsmen, though so close to them in lineage, so much on a level with their masters in essential physical qualities that to the last they could never be entirely subdued in spirit. Patient modern research, following the track of a deep-rooted national tradition veiled in the mythological figments which centre in what is called "The Return of the Heraclidae," reveals those northern immigrants or invaders, at various points on their way, dominant all along it, from a certain deep vale in the heart of the mountains of Epirus southwards, gradually through zone after zone of more temperate lowland, to reach their perfection, highlanders from first to last, in this mountain "hollow" of Lacedaemon. They claim supremacy, not as Dorian invaders, but as kinsmen of the old Achaean princes of the land; yet it was to the fact of conquest, to the necessity of [218] maintaining a position so strained, like that, as Aristotle expressly pointed out, of a beleaguered encampment in an enemy's territory, that the singular institutions of Lacedaemon, the half-military, half-monastic spirit, which prevailed in this so gravely beautiful place, had been originally due. But observe!--Its moral and political system, in which that slavery was so significant a factor, its discipline, its aesthetic and other scruples, its peculiar moral êthos,+ having long before our Platonic student comes thither attained its original and proper ends, survived,--there is the point! survived as an end in itself, as a matter of sentiment, of public and perhaps still more of personal pride, though of the finer, the very finest sort, in one word as an ideal. Pericles, as you remember, in his famous vindication of the Athenian system, makes his hearers understand that the ends of the Lacedaemonian people might have been attained with less self-sacrifice than theirs. But still, there it remained, hê diaita Dôrikê+--the genuine Laconism of the Lacedaemonians themselves, their traditional conception of life, with its earnestness, its precision and strength, its loyalty to its own type, its impassioned completeness; a spectacle, aesthetically, at least, very interesting, like some perfect instrument shaping to what they visibly were, the most beautiful of all people, in Greece, in the world.
