The extract below is from a very attractive web site (with sound effects and superb pictures) called "Landscape Perception" -- created through cooperation between Paul Devereux and Profs Tim Darvill and Geoffrey Wainwright. The emphasis is on the manner in which ancient man might have perceived his environment and landscape. As one might expect from the involvement of the two professors, there is a lot in this site to do with healing springs, magical properties of rocks and water, and so forth -- and I have already had a good go at much of that. So I will desist here.
A Stone Age Holy Land?
The idea that eastern Preseli was a sort of Holy Land deserves closer examination. Here is an extract from Chapter 5 of "The Bluestone Enigma."
Herbert Thomas and Richard Atkinson, in developing the Bluestone Myth, referred frequently to the eastern part of Preseli as a land of very special qualities, associated with mysteries and magic. They cited authorities including Sir Cyril Fox and Prof WF Grimes in support of the idea that Preseli was a sacred mountain. However, many of the references to “enchanted” Preseli relate not to the eastern part of the ridge but to Preseli as a whole -- ie the whole district including the upland part of Pembrokeshire and indeed many of the northern lowlands as well. There is nothing in the Mabinogion which suggests any special reverence for the Carn Meini area, and nothing in the local folklore tradition either. In the course of my “Pembrokeshire Folk Tale Project” I have collected almost 600 tales, legends, myths and anecdotes, and they come from all over the county. Tales and traditions are not specially concentrated in the eastern part of Preseli, and if I was asked to name the localities in Pembrokeshire which are associated with magic, sanctity or mystery I would -- without hesitation -- list Cwm Gwaun, followed by the St David’s area and Carningli as the top three. Carn Meini would not figure in my Top Twenty.
