Lucian De saltatione 25

[25] (the wisest of men, if we may believe Apollo, who said so) not only commended it but wanted to learn it, attributing the greatest value to observance of rhythm and music, to harmonious movement and to gracefulness of limb; and he was not ashamed, aged as he was, to consider it one of the most important subjects of study. ¹ He would, of course, be uncommonly enthusiastic over dancing, since he did not hesitate to study even what was trivial, and not only used to attend the schools of the flute-girls, but did not disdain to listen to serious discourse from Aspasia, a courtesan. ² Yet the art was just beginning when he saw it then, and had not yet been elaborated to such a high degree of beauty. If he could see those who now have advanced it to the utmost, that man, I am sure, dropping everything else, would have given his attention to this spectacle alone; and he would not have had his young friends learn anything else in preference to it.

[25] Socrates—that wisest of men, if we may accept the judgement of the Pythian oracle—not only approved of dancing, but made a careful study of it; and, in his zeal for grace and elegance, for harmonious movement and carriage of the body, thought it no shame, reverend sage that he was, to rank this among the most important branches of learning. And well might he have an enthusiasm for dancing, who scrupled not to study the humblest arts; who frequented the schools of the flute-girls, and could stoop to learn wisdom from the mouth of an Aspasia. Yet in his days the art was in its infancy, its beauties undeveloped. Had Socrates seen the artists who have made modern Pantomime what it is, he would assuredly have given it his exclusive attention, and assigned it the first place in the education of youth.
