The trickster / clown contains both comedy and tragedy in a single character. The trickster does everything the other way around. They can change form and gender, and in general, they accelerate cultural development. They break the laws of the gods and of nature. The offenses usually take the form of gambling or theft. Tricksters can be cunning, foolish or both at the same time. There is a duality embodied in the actions of the trickster since they on the one hand can seem vicious, but usually end up effecting change that is ultimately positive.
In Greek and Nordic myths, the trickster and the hero are often combined. Prometheus, for instance, stole the fire from the gods, and gave it to man, and thus could both be seen as a hero and a trickster.
