We see now from my previous two decipherments of Carn Arthur and Carn Meini that the standing stones of Bedd Arthur are in fact "located" at King Arthur's "bed'", which is the fixed circle of precession, surely marked here at the star Pi Cephei.
The Tip of the "pyramid" of Cepheus -- surely the astronomical origin of the concept of "pyramid-building", if astronomy played a role at inception -- is marked by the star Gamma Cephai, known as Er Rai, thought to be of Arabic origin as Al Rai, the Shepherd, but more likely simply "Rex", "the King", since the King's Head is ordinarily said to be marked by the Cepheus stars of delta, epsilon, zeta and lambda (see Richard Hinckley Allen, Star Names, p. 158), but that is of course nonsense, since those are in the left corner of Cepheus at the base of the pyramid, and much too small in grouping to be the King's head, located also right where Cepheus connects to the river of the Milky Way.

What our decipherment of the hermetic planisphere of Pembrokeshire, Wales suggests then is that a most singular outcrop of Carn Bica provides us with nothing less than a sculpture of King Arthur's head personally (see the image above).
