Many postcolonial scholars (e.g., Octave Mannoni) view characters Ariel and Caliban from William Shakespeare's The Tempest as representations of slavery. In that sense, Ariel is considered to be the good slave, who believes in negotiation and loyal servitude, whereas Caliban is thought to represent a cunning slave with a resentment against his master, namely Prospero. In fact, there have been subsequent plays based on The Tempest which took place in slavery-linked locations such as Haiti and Cuba.
