In 2001, a team of archaeologists found four skeletons at the site, one of them a male who had died c. 1600 BC, and another a female who had died c. 1300 BC. At first, the researchers did not realise they were dealing with mummies, since the soft tissue had decomposed and the skeletons had been buried.[7] But tests revealed that the two bodies had not been buried until about 1120 BC[8] and that the bodies had been preserved shortly after death in a peat bog for 6 to 18 months. The preserved bodies were then apparently retrieved from the bog and set up inside a dwelling, presumably having religious significance. Archaeologists do not know why the bodies were buried centuries later. The Cladh Hallan skeletons differ from most bog bodies in two respects: unlike most bog bodies, they appear to have been put in the bog for the express purpose of preservation (whereas most bog bodies were simply interred in the bog), and unlike most bog bodies, their soft tissue was no longer preserved at the time of discovery.
The high level of the calcareous sand in Cladh Hallan and the Scottish Highlands had been attributed in part to the preservation of the mummies over thousands of years.[9]
Analysis
This section needs to be updated. Please help update this article to reflect recent events or newly available information.(January 2017)
The skeletons and other finds are being analysed in laboratories in Scotland, England, and Wales. Following the provisions of the Treasure Trove Act, all the finds from Cladh Hallan, including the skeletons, will be allocated to a Scottish museum after the lengthy process of analysis and reporting is completed. According to recent anthropological and DNA-analysis, the skeletons of a female and a male were compiled from body parts of at least 6 different human individuals.[8][10]
