"Attend me briefly while I now disclose How art of fable telling first arose. Unhappy slaves, in servitude confined, Dared not to harsh masters show their mind, But under veiling of fable’s dress Contrived their thoughts and feelings to express, Escaping still their lords’ affronted wrath. So Aesop did; I widen out his path."
