The Jester is often conflated with the trickster, and they are not the same. Jung wrote about the trickster in an essay on the figure in Paul Radin's study of the Winnebago cycle, describing it as a shadow figure of the collective, amoral, appetitive, both creator and destroyer, and definitely not amusing in the way a jester is. Trickster figures in the traditions the atlas records, Coyote among many Native American peoples, Anansi in west Africa and the Caribbean, Loki in the Norse material, Eshu in Yoruba religion, Hermes in Greece, are religiously serious figures who cross boundaries, break rules and thereby establish them, and several are actively dangerous. Reducing them to comic relief flattens a category that scholars of religion treat with some care, and where the atlas records such figures it records them in their own traditions.
The essay collection at the source of Jung's trickster writing is itself worth naming precisely: Paul Radin's The Trickster: A Study in American Indian Mythology (1956), presenting Radin's own ethnographic translation of the Winnebago (Ho-Chunk) trickster cycle, accompanied by two separate interpretive essays, one by the classicist Karl Kerényi situating the figure within Greek and broader mythological parallels, and Jung's own psychological commentary reading the trickster as an archaic, undifferentiated forerunner of the later-developed Shadow archetype. The three-part structure, ethnographic text plus two independent scholarly readings, is a genuine and still-cited work of comparative mythology, distinct from anything in the twelve-archetype marketing literature.
