"(1) In original Greek tragedy, the prologue was either the action or a set of introductory speeches before the first entry (parados) of the chorus. Here, a single actor's monologue or a dialogue between two actors would establish the play's background events. (2) In later literature, a prologue is a section of any introductory material before the first chapter or the main material of a prose work, or any such material before the first stanza of a poetic work." <a href="cwrc:509015ff-7641-473e-94c5-688e06952bb7">(L.
