Lamachus: Ah! the Generals! they are numerous, but not good for much! (tr. Athen. 1912, vol. 1, Perseus) - Aristophanes

There is no beast more stubborn than a woman.
And neither fire nor leopard is more ruthless.

But how should women perform so wise and glorious an achievement, we women who dwell in the retirement of the household, clad in diaphanous garments of yellow silk and long flowing gowns, decked out with flowers and shod with dainty little slippers?

Epops: The wise can often profit by the lessons of a foe, for caution is the mother of safety. It is just such a thing as one will not learn from a friend and which an enemy compels you to know. To begin with, it's the foe and not the friend that taught cities to build high walls, to equip long vessels of war; and it's this knowledge that protects our children, our slaves and our wealth. Leader of the Chorus [leader]: Well then, I agree, let us first hear them, for that is best; one can even learn something in an enemy's school. (tr. O'Neill 1938, Perseus)
