Residues of fat discovered on pottery near the ancient site may indicate sleds used to move the stones were greased with lard.
's enormous rocks may have been transported to the prehistoric site with the help of pig fat, a scientist has said. Archaeologist Lisa-Marie Shillito say residues of fat on pottery discovered near the monument suggest Neolithic people greased the sleds used to move the huge stones with lard.
It has long been known that many of the rocks used to construct Stonehenge did not come from the site. The largest of the stones, known as the sarsen trilithons, are over 25 feet in height and weigh over 30 tons. These were moved from a site 18 miles away. The smaller"bluestones" came from quarries 160 miles away in west Wales. It is thought that the Neolithic people used sleds to roll them along., researchers examined how the stones were quarried.
Researchers have also previously suggested these sledges were greased to help move them along—past experiments show the most efficient way to transport them would be a greased timber slipway. However, physical evidence to back this up was lacking—the logs used for the sledges are unlikely to have been preserved., Shillito, from the U.K.'s Newcastle University, has said fat residues found on pottery near Stonehenge may help back the greased sled theory.
"Cooking/food has usually been the default assumption in archaeology when analysing pottery residues," she told."It's the most obvious explanation and often correct, but sometimes things are a bit more complex and it's important not to stick with the immediately obvious and consider other possibilities. In this case it could be a 'dual purpose'—cooking and collecting the fat as a by-product.
