A prologue or prolog (from Greek πρόλογος prólogos, from πρό pró, "before" and λόγος lógos, "word") is an opening to a story that establishes the context and gives background details, often some earlier story that ties into the main one, and other miscellaneous information. The Ancient Greek prólogos included the modern meaning of prologue, but was of wider significance, more like the meaning of preface. The importance, therefore, of the prologue in Greek drama was very great; it sometimes almost took the place of a romance, to which, or to an episode in which, the play itself succeeded. Latin On the Latin stage the prologue was often more elaborate than it was in Athens, and in the careful composition of the poems which Plautus prefixes to his plays we see what importance he gave to this portion of the entertainment; sometimes, as in the preface to the Rudens, Plautus rises to the height of his genius in his adroit and romantic prologues, usually placed in the mouths of persons who make no appearance in the play itself. Molière revived the Plautian prologue in the introduction to his Amphitryon. Racine introduced Piety as the speaker of a prologue which opened his choral tragedy of Esther. The tradition of the ancients vividly affected our own early dramatists. Not only was the mystery plays and miracles of the Middle Ages begun by a homily, but when the drama in its modern sense was inaugurated in the reign of Elizabeth, the prologue came with it, directly adapted from the practice of Euripides and Terence. Sackville, Lord Buckhurst, prepared a sort of prologue in the dumb show for his Gorboduc of 1562; and he also wrote a famous Induction, which is, practically, a prologue, to a miscellany of short romantic epics by diverse hands. Elizabethan Prologues of Renaissance drama often served a specific function of transition and clarification for the audience. A direct address made by one actor, the prologue acted as an appeal to the audience's attention and sympathy, providing historical context, a guide to themes of the play, and occasionally, a disclaimer. In this mode, a prologue, like any scripted performance, would exist as the text, the actor who speaks that text, and the presentation of the language as it is spoken. In ushering the audience from reality into the world of the play, the prologue straddles boundaries between audience, actors, characters, playwrights—basically,
