Crates of Thebes | Demetrius of Phalerum, On Style 170

<blockquote>170. Even sensible persons will indulge in jests on such occasions as feasts and carousals, or when they are addressing a word of warning to men inclined to good living. A refer- ence to ' the far-gleaming meal-bag ' may then be found salutary. The same may be said of the poetry of Crates ; and it would be well if you were to read the ' Praise of the Lentil ' in a party of free-livers. The Cynic humour is, for the most part, of this character. Such jests, in fact, play the part of maxims and admonitions.
