Kathleen Jenks says, in the section of Mything Links on Labyrinths,
Since labyrinths are human made, it might seem strange that I would include them on a page about the lore and sacredness of landscape. Labyrinths, however, seem to have been created as a response to energy currents in the land itself [note: as well as in human beings, sometimes known as the chi force - ed.] -- currents sometimes called "telluric forces." It may be that labyrinths help humans re-attune to the earth by echoing and re-creating, in a microcosm, earth's own fields of sacred power. The following sites reflect both the informational and experiential dimensions of labyrinths. . . .
From Labyrinth comes this intriguing (albeit fairly technical) paper, "History and Interpretations of the Labyrinth Motif in Native North American Cultures" by Joshua Schriftman. His primary focus is on the 7-circuit Hopi Tápu'at labyrinths (he points out that 7-fold labyrinths are found only in ancient Eurasia and among Native Americans; the more famous 11-fold designs -- or 12, counting the central circle -- are all from medieval Europe and obviously influenced by Christian symbolism involving the number twelve). In addition to labyrinths, per se, Schriftman considers the seven vibratory centers (chakras) in humans as well as corresponding centers in the earth; the role of Spider Woman and her twin sons in setting up earth's vibratory centers; emergence myths; peyote and mushrooms; spiral dances as fertility rituals; and the role of the kiva in its relationship to labyrinths. (Note: as of 10/28/99, the paper's illustrations are yet to be added to the site. Ditto 4/7/01.)
Sacred 12-circuit Christian Labyrinth
...
Examples of these Labyrinth are carved on a rock south of Oraibi, and south of Shipaulovi. A combination of the two forms is also carved on a wooden stick which is planted in front of the One Horn altar in the Kwani kiva at Walpi during the Wúwuchim ceremony.
The symbol is commonly known as Tápu'at [Mother and Child]. This type represents spiritual rebirth from one world to the succeeding one, as symbolized by the Emergence itself."

Botticelli's Labyrinth
In his commentary included in the book The Gospel of the Holy Twelve [transcription in process]; by G.J. Ouseley; Edson Printers, London, 1923. E. F. Udny tells us that Botticelli represented the ancient Egyptian labyrinth in one of his engravings. He further states "We have reproduced this labyrinth and adapted it for Christian rites".
Utney goes on to say, "There appears to have been a similar labyrinth in Jerusalem before the demolition ordered by Hadrian. This may well have been used by the early Christians in receiving candidates for admission into the Church."
