An analysis of fossilised animal bones is revealing how early inhabitants of Ireland lived and gathered in mass congregations at one of the country ’s most iconic archaeological sites .
A collaborative squad of research worker from Cardiff University , Queen ’s University Belfast , Memorial University Newfoundland , and the British Geological Survey analyse the bones of 35 brute turn up from Navan Fort , a prehistoric Irish ceremonial substance that date from the 4th to the 1st century BCE . Results suggest that masses transported animate being long distances in lodge to gather for ceremonial and ritualistic purposes .
“ The result provide clear-cut grounds that community of interests in Iron Age Ireland were very mobile and that stock were also moved over considerable distances , ” write the authors inScientific Reports .
Navan Fortis one of the expectant ceremonial centers of ancient Ireland and has been documented in both historical and mythologic accounts . Considered to be the fabled capital of Ulster in the northern part of the country , the site was largely give up by the former medieval period but continued to be assort with kings and king . The website is characterized by a big orbitual enclosure measuring 250 m ( 820 feet ) broad with an interior structure that is cerebrate to have covered a circular ceremonial wooden structure 40 meters ( 131 infantry ) astray . Today , this 2,000 - year - sometime “ synagogue ” of sorting is address by soil .
To come to their conclusions , researcher conduct a multi - isotope depth psychology on sampling of tooth enamel . When animals eat or imbibe , chemical signal are file away on their tooth that provide scientists to hound their original geographical expanse . Such investigation are particularly useful at site where human remains have not been found . ( Just one human clavicle has been disclose at Navan Fort . )
" In the absence seizure of human remains , multi - isotope analysis of animals found at Navan Fort provides us with the best reading of human movement at that time , ” said study co - source Dr Finbar McCormick , of Queen ’s University , Belfast , in astatement
" Feasting , almost invariably associated with ritual killing , was a societal necessity of former societies where the slaughter of a large domesticate necessitated the consumption of a large amount of marrow in a shortsighted point of time . "
The large sizing of the structures at Navan Fort and the many animal remains signal that people probably traveled great distances to attain the goal . But why and when these ancient people traveled to the site for the most part remains a mystery .
" Our results furnish clear evidence that communities in Iron Age Ireland were very mobile and that livestock were also moved over greater distances than was antecedently thought , ” aver pencil lead report writer Dr Richard Madgwick , base in Cardiff University ’s School of History , Archaeology and Religion . " The high symmetry of pig remains establish there is very rare for this period . This indicate that Navan Fort was a banquet sum , as pig are well - suited as junket fauna and in former Irish literature pork is the preferred food of the feast .
" It is clear that Navan Fort had a vast catchment and that the influence of the site was far - reaching , ” he added
