Queen Elizabeth I ruled from 1558 to 1625. Elizabethan Era, also known as the Renaissance, was period when theater, politics, and education flourished. Culture also prospered, with names like William Shakespeare and Christopher Marlowe. Since there were no theatre buildings in the beginning of the Elizabethan era, performances were staged in the courtyards of inns and the private homes of nobles. The earliest theatre, known as The Theatre, was established in 1576 by James Burbage. Elizabethans believed in two equally powerful supernatural forces, God and Lucifer. Demons were thought to be malicious supernatural beings with the power to possess people and wreak havoc in the lives of the Elizabethans. These ideas were based on religious teachings which emphasized the existence of evil trying to corrupt and entice people. Their beliefs were incorporated into texts and drama of the period, and demons became one of the things that attracted the audience's interest. Both Doctor Faustus and Volpone, or the Fox introduce readers and audiences to two demonic figures, Mephistopheles and Volpone.
