Lastly, what holds good of real life is true also of its counterfeit in jest and play, which everywhere, and especially in the earliest period of full and simple existence, do not exclude the serious, but veil it. The simplest elements of art are in Latium and Greece quite the same; the decorous armed dance, the "leap" (-triumpus-, --thriambos--, --di-thyrambos--); the masquerade of the "full people" (--satyroi--, -satura-), who, wrapped in the skins of sheep and goats, wound up the festival with their jokes; lastly, the pipe, which with suitable strains accompanied and regulated the solemn as well as the merry dance. Nowhere, perhaps, does the especially close relationship of the Greeks and Italians come to light so clearly as here; and yet in no other direction did the two nations manifest greater divergence as they became developed. The training of youth remained in Latium strictly confined to the narrow limits of domestic education; in Greece the yearning after a varied yet harmonious training of mind and body created the sciences of Gymnastics and Paideia, which were cherished by the nation and by individuals as their highest good.
Latium in the poverty of its artistic development stands almost on a level with uncivilized peoples; Greece developed with incredible rapidity out of its religious conceptions the myth and the worshipped idol, and out of these that marvellous world of poetry and sculpture, the like of which history has not again to show. In Latium no other influences were powerful in public and private life but prudence, riches, and strength; it was reserved for the Greeks to feel the blissful ascendency of beauty, to minister to the fair boy-friend with an enthusiasm half sensuous, half ideal, and to reanimate their lost courage with the war-songs of the divine singer.
