The Hopi maintain a complex religious and mythological tradition stretching back over centuries. However, it is difficult to definitively state what all Hopis as a group believe. Like the oral traditions of many other societies, Hopi mythology is not always told consistently and each Hopi mesa, or even each village, may have its own version of a particular story, but "in essence the variants of the Hopi myth bear marked similarity to one another."[1] It is also not clear that the stories told to non-Hopis, such as anthropologists and ethnographers, represent genuine Hopi beliefs or are merely stories told to the curious while keeping safe the more sacred Hopi teachings. As folklorist Harold Courlander states, "there is a Hopi reticence about discussing matters that could be considered ritual secrets or religion-oriented traditions."[2]
