Like rats, monkeys also have a duality of nature. In Chinese mythology, Sun Wukong is the Monkey King. He learned the art of magic and increased in strength until he overthrew the other gods and goddesses in Heaven and was imprisoned in rock by the Jade Emperor. Conversely, in Indian folklore, Hanuman the Monkey is revered for his loyalty, bravery and devotion to justice. In modern culture, Planet of the Apes" shows a tyrannical side of the simians, while Curious George" takes his handler on a series of innocent misadventure. The two sides of the nature of monkeys mirror the two sides of the nature of humans. Some humans, such as the Zodiac Killer, become mass murderers. Other humans, such as Mother Theresa, devote their lives to the service of others. The similar dual nature of both man and ape allows Banksy to use the two species interchangeably in many of his graffiti pieces.
