Xenophon Symposium 9

[1]
  Their conversation ended here. Autolycus got up to go out for a walk (it being now his usual time); and his father Lycon, as he was departing to accompany him, turned back and said: So help me Hera, Socrates, you seem to me to have a truly noble character.

[2]
  After he had withdrawn, a chair of state, first of all, was set down in the room, and then the Syracusan came in with the announcement: Gentlemen, Ariadne will now enter the chamber set apart for her and Dionysus; after that, Dionysus, a little flushed with wine drunk at a banquet of the gods, will come to join her; and then they will disport themselves together.

[3]
  Then, to start proceedings, in came Ariadne, apparelled as a bride, and took her seat in the chair. Dionysus being still invisible, there was heard the Bacchic music played on a flute. Then it was that the assemblage was filled with admiration of the dancing master. For as soon as Ariadne heard the strain, her action was such that every one might have perceived her joy at the sound; and although she did not go to meet Dionysus, nor even rise, yet it was clear that she kept her composure with difficulty.

[4] But when Dionysus caught sight of her, he came dancing toward her and in a most loving manner sat himself on her lap, and putting his arms about her gave her a kiss. Her demeanour was all modesty, and yet she returned his embrace with affection. As the banqueters beheld it, they kept clapping and crying encore!

[5] Then when Dionysus arose and gave his hand to Ariadne to rise also, there was presented the impersonation of lovers kissing and caressing each other. The onlookers viewed a Dionysus truly handsome, an Ariadne truly fair, not presenting a burlesque but offering genuine kisses with their lips; and they were all raised to a high pitch of enthusiasm as they looked on.

[6] For they overheard Dionysus asking her if she loved him, and heard her vowing that she did, so earnestly that not only Dionysus but all the bystanders as well would have taken their oaths in confirmation that the youth and the maid surely felt a mutual affection. For theirs was the appearance not of actors who had been taught their poses but of persons now permitted to satisfy their long-cherished desires.

[7] At last, the banqueters, seeing them in each other’s embrace and obviously leaving for the bridal couch, those who were unwedded swore that they would take to themselves wives, and those who were already married mounted horse and rode off to their wives that they might enjoy them. As for Socrates and the others who had lingered behind, they went out with Callias to join Lycon and his son in their walk.
  So broke up the banquet held that evening.
