humans continue to think of themselves as separate. Where there is no clear boundary between human and animal, there is a sense of fear. This has been the case at least since the Minotaur (half-man, half-bull; flesh-eating). In The Tempest, a man called Prospero rules an island, and enslaves its native inhabitant, a strange creature called Caliban. Like the Minotaur, Caliban’s identity is unclear – when a man called Trinculo first encounters him, he cannot work out what Caliban’s body is. It is both human and non-human, and this is disturbing to Trinculo:
