History of the Peloponnesian War

But the moderate kind of garment, and conformable to the wearing of these times, was first taken up by the Lacedaemonians, amongst whom also, both in other things and especially in the culture of their bodies, the nobility observed the most equality with the commons.

The same were also the first that when they were to contend in the Olympic games stripped themselves naked and anointed their bodies with ointment; whereas in ancient times the champions did also in the Olympic games use breeches, nor is it many years since this custom ceased. Also there are to this day amongst the barbarians, especially those of Asia, prizes propounded of fighting with fists and of wrestling, and the combatants about their privy parts wear breeches in the exercise.

It may likewise by many other things be demonstrated that the old Greeks used the same form of life that is now in force amongst the barbarians of the present age.
