The Greeks themselves, quoted more than once above, have put us on the right track in this inquiry. However paiderastia began in Hellas, it was encouraged by gymnastics and syssitia. Youths and boys engaged together in athletic exercises, training their bodies to the highest point of physical attainment, growing critical about the points and proportions of the human form, lived of necessity in an atmosphere of mutual attention. Young men could not be insensible to the grace of boys in whom the bloom of beauty was unfolding. Boys could not fail to admire the strength and goodliness of men displayed in the comeliness of perfected development. Having exercised together in the wrestling-ground, the same young men and boys consorted at the common tables. Their talk fell naturally upon feats of strength and training; nor was it unnatural, in the absence of a powerful religious prohibition, that love should spring from such discourse and intercourse. The nakedness, which Greek custom permitted in gymnastic games and some religious rites, no doubt contributed to the erotic force of masculine passion; and the history of their feeling upon this point deserves notice. Plato, in the _Republic_ (452), observes that "not long ago the Greeks were of the opinion, which is still generally received among the barbarians, that the sight of a naked man was ridiculous and unseemly." He goes on to mention the Cretans and the Lacedæmonians as the institutors of naked games. To these conditions may be added dances in public, the ritual of gods like Erôs, ceremonial processions, and contests for the prize of beauty. The famous passage in the first book of Thucydides (cap. vi.) illustrates the same point. While describing the primitive culture of the Hellenes, he thinks it worth while to mention that the Spartans, who first stripped themselves for running and wrestling, abandoned the girdle which it was usual to wear around the loins. He sees in this habit one of the strongest points of distinction between the Greeks and barbarians. Herodotus insists upon the same point (book i. 10), which is further confirmed by the verse of Ennius: "Flagitii," &c. The nakedness which Homer (_Iliad_, xxii. 66) and Tyrtæus (i. 21) describes as shameful and unseemly is that of an old man. Both poets seem to imply that a young man's naked body is beautiful even in death.
