The Wolf, the Fox, and the Ape

The Fables of Phædrus
Whoever has once become notorious by base fraud, even if he speaks the truth, gains no belief. To this, a short Fable of Æsop bears witness.
A Wolf indicted a Fox upon a charge of theft; the latter denied that she was amenable to the charge. Upon this, the Ape sat as judge between them; and when each of them had pleaded his cause, the Ape is said to have pronounced this sentence: “You, Wolf, appear not to have lost what you demand; I believe that you, Fox, have stolen what you so speciously deny.”
