When Sidonius, who had a great reputation at Athens as a teacher, was boasting that he was conversant with all the philosophic systems—but I had better quote his words. ‘Let Aristotle call, and I follow to the Lyceum; Plato, and I hurry to the Academy; Zeno, and I make my home in the Porch; Pythagoras, and I keep the rule of silence.’ Then rose Demonax from among the audience: ‘Sidonius, Pythagoras calls.’

A pretty girlish young man called Python, son of some Macedonian grandee, once by way of quizzing him asked a riddling question and invited him to show his acumen over it. ‘I only see one thing, dear child,’ he said, ‘and that is, that you are a fair logician.’ The other lost his temper at this equivoque, and threatened him: ‘You shall see in a minute what a man can do.’ ‘Oh, you keep a man, do you?’ was Demonax’s smiling retort.
