This union of strength and beauty belongs especially to the time of full-grown youth and opening manhood. It is the age when the Greek youth began to undertake some of the duties of citizenship, and when the state took upon itself his training. In most Greek cities somewhere between the ages of sixteen and eighteen the youths were enrolled in corps, and for two years were subject to a strict military discipline under officers appointed by the state. They learnt to use their weapons and to ride; they hardened their bodies by athletic exercises and hunting; they gained practical experience in war by acting as police patrols on the frontiers. This time of life was especially devoted to athletics and physical training. At many of the games there were special competitions for youths of this age—the beardless or ἀγένειοι. To the same age belong these romantic boy friendships which figure so largely in Greek life, from the time of Harmodius and Aristogeiton or earlier. That these friendships did at times lead to serious abuse cannot, unfortunately, be denied. But the charge of immorality brought against them seems to me greatly exaggerated,[110] at least as far as regards the fifth century and the most enlightened states. These friendships arose on the one side from the natural hero-worship of youth, on the other from an intense appreciation of bodily beauty. This strong artistic feeling is illustrated by the practice which arose among the vase painters of inscribing on their cups the name of some popular youth with the word καλός, or sometimes the more general inscription καλὸς ὁ παῖς, “the boy is fair.” The term “love names” applied to these inscriptions is somewhat unfortunate. The word καλός implies none of that modern maudlin sentimentality so often mistaken for love, but rather the artist’s sense of the beautiful, sometimes his admiration for some popular youth, sometimes, perhaps, merely his satisfaction in the form he has himself created. The point, however, which interests us here is that the beauty which appealed to the Greek of the latter half of the fifth century was not the beauty of woman, nor even of the mature man, but the beauty of manly youth, and the art of the Periclean age has been well described as the glorification of the ephebos.
