Marlowe had a dissolute and turbulent life. He was the greatest playwright before Shakespeare. He is not very famous because He died very young during a quarrel in a tavern, where He was stubbed in the eye.
The scholar Faustus, who has achieved all the human knowledge, wants to learn the secrets of matter and the universe. So He turns his attention to the magic and the dark arts. With his incantations Faustus meets Mephistopheles, the devil's advocate, who offers him limitless power and knowledge in exchange for his soul.
The contract last 24 years during which Faustus can have and do anything, He wants even, He knows, He will be damned. He even calls the spirit of Helen of Troy, but as the end of the contract and of his life approaches, Faustus begins to regret his decision. It is all useless and He is taken to hell by the devils.
SOLILOQUY OR MONOLOGUE
It is a moment during which the main character is alone on the scene with other characters who listen and don't speak and He expresses his inner thoughts and feelings. The most famous (important) example of interior monologue is Hamlet's monologue. Hamlet is alone on the stage speaking to himself and expressing his dilemma: "to be or not to be". The first example of monologue during the Elizabethan theater is Doctor Faustus. Faustus is alone on the scene, It is eleven o' clock and He knows that, at midnight, He must give his soul to the devil. It is a struggle between good and evil (the same struggle is in the Morality Plays but here It is more superficial).
