I have already had an interest in why certain types of stone/materials were used for building certain types of structures.
Quote:And, according to an article in the October 2008 issue of Smithsonian magazine, some archaeologists think the megaliths at the monument, particularly the so-called bluestones, could have been used for healing purposes. At any rate, it’s truly astonishing to realize that Neolithic people (perhaps the Druids) had the technical skills for moving megaliths weighing as much as 50 tons from as far away as the Preseli Mountains in Wales, some 250 miles from Stonehenge! One thing about Stonehenge remains certain - it will continue to amaze for years to come.
Quote:Now, a study published this month in the Journal of Archaeological Science sheds new light on the long-running argument. According to analysis of the Stonehenge bluestones by a team of scientists from Aberystwyth University, University College London and National Museum of Wales, the stones did not come from the Carn Meini outcrop as Thomas concluded. Instead, by using laser mass spectrometry techniques to analyze both the chemical composition of the rock and the microbiology present when it was formed, they traced at least 55 percent of the spotted dolerite bluestones used at Stonehenge to Carn Goedog, a different outcrop several kilometers away.
Quote:Although they concede Stonehenge was probably "multifunctional", possibly also serving as a giant calendar marking the solstices, as well as a site of ancestor worship, they are convinced its true importance came from the modest bluestones, the size of a man or smaller, dwarfed by the awesome sarsens.
Two of the original bluestones were broken, many chipped into fragments, and some survive only as stumps underground after being broken up to serve as healing talismans.
Quote:According to this competing school of thought, an Ice Age glacier carried the bluestones to the Wiltshire region some 20,000 years ago, and they were already available locally when Neolithic man began building Stonehenge.
