Let’s answer Socrates himself. Xenophon writes (Symposium 2:16–23):
“Assuredly,” replied Socrates; “and I remarked something else, too,—that no part of his body was idle during the dance, but neck, legs, and hands were all active together. And that is the way a person must dance who intends to increase the suppleness of his body. And for myself,” he continued, addressing the Syracusan, “I should be delighted to learn the figures from you.”
“What use will you make of them?” the other asked.
“I will dance, by Zeus.”
This raised a general laugh; but Socrates, with a perfectly grave expression on his face, said: “You are laughing at me, are you? Is it because I want to exercise to better my health? Or because I want to take more pleasure in my food and my sleep? Or is it because I am eager for such exercises as these, not like the long-distance runners, who develop their legs at the expense of their shoulders, nor like the prize-fighters, who develop their shoulders but become thin-legged, but rather with a view to giving my body a symmetrical development by exercising it in every part?
Or are you laughing because I shall not need to hunt up a partner to exercise with, or to strip, old as I am, in a crowd, but shall find a moderate-sized room1 large enough for me (just as but now this room was large enough for the lad here to get up a sweat in), and because in winter I shall exercise under cover, and when it is very hot, in the shade?
Or is this what provokes your laughter, that I have an unduly large paunch and wish to reduce it? Don't you know that just the other day Charmides here caught me dancing early in the morning?”
“Indeed I did,” said Charmides; “and at first I was dumbfounded and feared that you were going stark mad; but when I heard you say much the same things as you did just now, I myself went home, and although I did not dance, for I had never learned how, I practised shadow-boxing, for I knew how to do that.”
“Undoubtedly,” said Philip; “at any rate, your legs appear so nearly equal in weight to your shoulders that I imagine if you were to go to the market commissioners and put your lower parts in the scale against your upper parts, as if they were loaves of bread,1 they would let you off without a fine.”
“When you are ready to begin your lessons, Socrates,” said Callias, “pray invite me, so that I may be opposite you in the figures and may learn with you.”
To begin with, since the company had applauded the way the boy's natural beauty was increased by the grace of the dancing postures, Philip made a burlesque out of the performance by rendering every part of his body that was in motion more grotesque than it naturally was; and whereas the girl had bent backward until she resembled a hoop, he tried to do the same by bending forward. Finally, since they had given the boy applause for putting every part of his body into play in the dance, he told the flute girl to hit up the time faster, and danced away, flinging out legs, hands, and head all at the same time; and when he was quite exhausted, he exclaimed as he laid himself down: “Here is proof, gentlemen, that my style of dancing, also, gives excellent exercise; it has certainly given me a thirst; so let the servant fill me up the big goblet.”
What we learn from this:
- At a symposium it was common to have girls and boys dancing for entertainment. The older men liked to see the gracious movements.
- Socrates, when he was around 70 years old, practiced solo dancing to keep himself in shape.
- This was not common for old men, so it provoked laughter. Charmides said that he had never learnt to dance, so he did shadow-boxing instead.
- After Socrates had encouraged him, Callias started to dance and found that it was quite exhausting.
This is similar to the scene of the symposium: a flute player and a dancer
