A study published this month in the journal Time & Mind has shown that the 'blue stones' of Stonehenge, quarried in the Preseli Hills of Wales and hauled some 200 miles to south-west England, may have been treasured for their sonic properties. Thousands of stones along the Carn Menyn ridge on Mynydd Preseli were tested, and a high proportion of them were found to "ring" when they were struck, a quality that has been highly valued in many ancient cultures.
The principal investigator on the project is a good friend of the Daily Grail, Paul Devereux (author of The Long Trip: A Prehistory of Psychedelia, available from Amazon US and Amazon UK). Here's what he told BBC News:
It hasn't been considered until now that sound might have been a factor. The percentage of the rocks on the Carn Menyn ridge are ringing rocks, they ring just like a bell. And there's lots of different tones, you could play a tune. In fact, we have had percussionists who have played proper percussion pieces off the rocks.
