Mobility and migration in late Iron Age and early Medieval Ireland

Strontium and oxygen isotope analysis has been performed on a selection of human teeth dating from late Iron Age and early Medieval Ireland to test the hypothesis that the appearance of new burial rites was associated with phases of migration from, and contact with, the Roman and Late Antique world. In particular, the appearance of crouched inhumations from the beginning of the 1st century CE, and the appearance of extended supine inhumations alongside the reappearance of crouched burials after the c. 4th century CE are investigated. Isotopic data favours the presence of non-local individuals during both periods. As parallels for virtually all of these new burial practices can be found elsewhere, for example throughout Iron Age and Roman Britain, the data are seen to support previously proposed theories that such burial practices were intrusive and reflected new rites associated with migrant peoples. This adds to the increasing body of evidence demonstrating that rather than being isolated, Ireland was very much part of a connected Europe throughout the entire period of Roman administration in the western provinces, and in the centuries after its demise
