Velie (compiler and editor), American Indian Literature: An Anthology, Revised edition, page 44, The trickster is one of the oldest and most widespread of mythological and literary figures. […] As the name implies, the trickster is, on one level—probably the most important—an amoral practical joker who wanders about playing pranks on unsuspecting victims […] With all the fluctuations, certain things about the trickster are predictable: he is always a wanderer, always hungry, and usually oversexed. Tricksters abound in folktales […] .
