στάσεως δέ ποτε Ἀθήνησι γενομένης εἰσῆλθεν εἰς τὴν ἐκκλησίαν καὶ φανεὶς μόνον σιωπᾶν ἐποίησεν αὐτούς· ὁ δὲ ἰδὼν ἤδη μετεγνωκότας οὐδὲν εἰπὼν καὶ αὐτὸς ἀπηλλάγη.
Once when the Athenians had collapsed into political discord, he went to the assembly and just by appearing, brought them to silence. When he saw they had relented, he excused himself without a word.
(Lucian, Life of Demonax)
