The Yei Rug depicts the "supernatural 'Holy People' who communicate between the Navajos and their gods." Frequently the Rainbow Yei is included surrounding the main figure group. They are believed to restore health when invoked in ceremony.
A Guid to Navajo Rugs
Yeibichai rugs represent ceremonies in which human dancers portray yeis. These figures are pictured in profile rather than face forward as is traditional with a Yei rug. At the head of the central group of dancers is usually a lead dancer while following behind is usually a clown character known as a "water sprinkler". Sometimes the medicine man and the patient for whom the dance is being performed are also depicted.
