Chapter 14. Aristophanes: Satirist versus Politician
ἐπίσταμαι διὰ τὴν πέρυσι κωμῳδίαν.
εἰσελκύσας γάρ μ’ ἐς τὸ βουλευτήριον
διέβαλλε καὶ ψευδῆ κατεγλώττιζέ μου
κἀκυκλοβόρει κἄπλυνεν, ὥστ’ ὀλίγου πάνυ
Later (502–503), Aristophanes writes, “A year ago, Kleon charged [diabalei] that I had slandered the State [tēn polin kakōs legō] in the presence of strangers, by presenting my play, The Babylonians, at our Great Festival of Dionysos.” 
ἡνίκα Κλέων μ’ ὑπετάραττεν ἐπικείμενος
†καί με κακίσταις? [???????, Briel] κακίσας, Briel] ἔκνισε· κᾆθ’ ὅτ’ ἀπεδειρόμην
οὑκτὸς ἐγέλων μέγα κεκραγότα θεώμενοι,
οὐδὲν ἄρ’ ἐμοῦ μέλον, ὅσον δὲ μόνον εἰδέναι
σκωμμάτιον εἴποτέ τι θλιβόμενος ἐκβαλῶ.
ταῦτα κατιδὼν ὑπό τι μικρὸν ἐπιθήκισα·
εἶτα νῦν ἐξηπάτησεν ἡ χάραξ τὴν ἄμπελον.
Thus, Aristophanes was apparently brought to court again, and his popular backing deserted him; he was, metaphorically, flayed alive by the Tanner. He was forced to some kind of truce with Cleon, which he later rejected at the time of Wasps.
This does portray a Socrates unruffled by Aristophanes’ play. But it also portrays a friend of Socrates who is clearly shocked at the extent of the abuse (“all manner of abuse … in every possible way”) directed at his friend. In addition, this fits into the familiar genre of Socratic stories in which he is seen as an extraordinarily wise man (it is prefaced by an explanation that wise men can control their anger, 10b). The point of the story is that one would expect Socrates to be upset, but he reacts with wisdom, self-control, and urbanity. If Old Comedy were a place where verbal attacks could not sting, the story and the characterization would be pointless.
