The Maidu lived in the central Sierra Nevada of California, to the north of Yosemite. The Maidu, who were not particularly numerous to begin with, were decimated by the incursion of Americans. These texts were collected by a linguist at the beginning of the 20th century.
In these texts Coyote is the central character. He is first seen in the company of Earth-Maker, giving him advice about how to build the world. The Maidu tales of Coyote are well known for being exceptionally transgressive; he is constantly seducing women by guile and deceit. While these stories are very entertaining, they shouldn't be taken to imply that this was normal behavior for Maidu. The trickster figure is an anti-hero, used as a way of defining the limits of the acceptable.
