The Tempest is the most alchemically influenced of all William Shakespeare's work, steeped as it is in alchemical imagery (dying Kings and sons, Ariel as the spirit Mercurius etc.) with Prospero as the archetypal Magus. The main character in the play Goodnight Desdemona (Good Morning Juliet), by Ann-Marie MacDonald, succeeds in determining the alchemy behind Shakespeare's Othello. Literary alchemy continues to be popular in novels such as Paulo Coelho's The Alchemist (1988).
