In mythology, and in the study of folklore and religion, a trickster is a character in a story (god, goddess, spirit, man, woman, or anthropomorphisation), which exhibits a great degree of intellect or secret knowledge, and uses it to play tricks or otherwise disobey normal rules and conventional behaviour. It is suggested by G. P. Hansen that the term "trickster" was probably first used in this context by Daniel G. Brinton in 1885.
Tricksters are archetypal characters who appear in the myths of many different cultures. Lewis Hyde describes the trickster as a "boundary-crosser". The trickster crosses both physical and often breaks societal rules. Tricksters "...violate principles of social and natural order, playfully disrupting normal life and then re-establishing it on a new basis."
Often, the bending/breaking of rules takes the form of tricks or thievery. Tricksters can be or foolish or both. The trickster openly questions and mocks authority. They are usually male characters, and are fond of breaking rules, boasting, and playing tricks on both humans and gods.
All cultures have tales of the trickster, a crafty creature who uses cunning to get food, steal precious possessions, or simply cause mischief. In some Greek myths Hermes plays the trickster. He is the patron of thieves and the inventor of lying, a gift he passed on to Autolycus, who in turn passed it on to Odysseus. In Slavic folktales, the trickster and the culture hero are often combined.
Frequently the trickster figure exhibits gender and form variability. In Norse mythology the mischief-maker is Loki, who is also a shape shifter. Loki also exhibits gender variability, in one case even becoming pregnant. He becomes a mare who later gives birth to Odin's eight-legged horse Sleipnir.
