Bush Barrow dagger studs - gold analysishttps://www.wiltshiremuseum.org.uk/2019/11/18/bush-barrow-dagger-studs-gold-analysis/?fbclid=IwAR1GLNV8PO8NeavNneSH01aG5p1Ca9Zjtk1CCty2GNkhjtC_Ck4ee16n1eU The results are now in! Did the Bronze Age gold, found in a burial close to Stonehenge, came from Britain, Ireland or Brittany. Located close to Stonehenge, Bush Barrow is Britain's richest Bronze Age burial. The most remarkable discovery was a gold-studded dagger pommel, set with thousands of microscopic gold studs thinner than a human hair. Using a recently developed scientific technique, Dr Chris Standish of Southampton University, has identified the most likely source of the gold used to make this amazing object - answering a question that has puzzled archaeologists for decades? Dr Standish has developed a metallurgical technique that analyses the proportions of different isotopes within the lead impurities in the gold. These proportions were compared with information about gold from known sources in Ireland, Cornwall, Wales and Brittany. A single gold stud was used for the analysis using X-ray Fluorescence - a non-destructive technique. The blade of the Bush Barrow dagger is of a type found in both Brittany and Britain and gold-studded pommels have been found on both sides of the English Channel. Some archaeologists have thought that the dagger pommel was made in Brittany as more have been found in Brittany but the craft skills needed to make the dagger pommel are higher than used in any other goldwork in either Britain or France at this early date. The dagger was buried with a Chieftain who died in about 1950BC at a time when Stonehenge was at the centre of an internationally important ceremonial landscape - the sarsen stone trilithons were erected in about 2,500BC and the bluestones from Wales were placed in their final positions at the site in about 1,600BC before Stonehenge finally went out of use in about 1,500BC. Analysis undertaken 30 years ago of gold objects from burials in the Stonehenge landscape suggested that the gold used came from Ireland. Analysis by Dr Standish of gold objects found in Ireland has shown that many are made of gold from Cornwall (see this article in the Independent by David Keys) and gold from Cornwall was also used in the famous Nebra Sky Disk found in Germany and displayed at the State Museum of Prehistory in Halle (see this article about the analysis of the Sky Disk). |
