Sarsen
Template:Short description Template:Use dmy dates
Sarsen stones are silicified sandstone blocks found extensively across southern England on the Salisbury Plain and the Marlborough Downs in Wiltshire; in Kent; and in smaller quantities in Berkshire, Essex, Oxfordshire, Dorset, and Hampshire.
GeologyEdit
Sarsen stones are the post-glacial<ref>Template:Cite journal</ref> remains of a cap of Cenozoic silcrete that once covered much of southern England. This is thought to have formed during Neogene to Quaternary weathering by the silicification of Upper Paleocene Lambeth Group sediments, resulting from acid leaching.<ref name="Stewart Ullyot">Template:Cite journal</ref>
EtymologyEdit
There are several potential sources for the word "sarsen."
The first is that word "sarsen" is a shortening of "Saracen stone" which arose in the Wiltshire dialect. In the Middle Ages, "Saracen" was a common name for Muslims, and came by extension to be used for anything regarded as non-Christian, whether Muslim or pagan in contrast to Christianity.<ref name="FS">Template:Cite book</ref>
The second is that "sarsen" is vernacular variation of the Indo-European "sasan," name given to the prehistoric vaults of the Chotanagpur plateau of Northern India.<ref name=":0">Template:Cite book</ref>
The third possibility is that "sarsen" comes from the hybrid Anglo-Saxon "sar-stan" or 'troublesome stone.' "Sar" has the meaning of 'grievous.'<ref name=":0" />
Human usesEdit
The builders of Stonehenge used these stones for the Heel Stone and sarsen circle uprights.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Avebury and many other megalithic monuments in southern England are also built with sarsen stones.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
While sarsen stones are not an ideal building material, fire and in later times explosives were sometimes employed to break the stone into pieces of a suitable size for use in construction. William Stukeley wrote that sarsen is "always moist and dewy in winter which proves damp and unwholesome, and rots the furniture".<ref>Template:Citation</ref><ref>Template:Citation</ref> In the case of Avebury, the investors who backed a scheme to recycle the stone were bankrupted when the houses they built proved to be unsaleable and also prone to burning down. However, despite these problems, sarsen remained highly prized for its durability, being a favoured material for steps and kerb stones.
