We investigated the skeletons of 27 Greenland Norse people excavated from churchyard burials from the late 10th to the middle 15th century.The stable carbon isotopic composition (delta (super 13) C) of the bone collagen reveals that the diet of the Greenland Norse changed dramatically from predominantly terrestrial food at the time of Eric the Red around AD 1000 to predominantly marine food toward the end of the settlement period around AD 1450.But now there is a swing towards, ‘Jeepers, they were fairly catastrophic’.” Their dead seem to have been buried on both sides of the Liffey and along the Poddle.Dublin was enclosed by a palisade running along the ridge from Dublin Castle to Christ Church, joining the two rivers.

From the dietary information obtained via the delta (super 13) C values of the bones we have calculated individual reservoir age corrections for the measured (super 14) C ages of each skeleton.

The sheer quantity of artefacts buried points to the importance and wealth of Dublin at the time. At least 59 graves were found in the Kilmainham-Islandbridge area between the late 18th century and 1934.

Most date from between AD 841, when a longphort was established, and AD 902. Some still turn up; in 2004, a Viking sword and spearhead were unearthed in the War Memorial Park.

Human remains of a young male were later found; analysis indicated a non-local who had spent his early years in the Scandinavian region.

“There is something phenomenal happening in Dublin,” says archaeologist Linzi Simpson.

Recent re-dating of the remains, applying the appropriate marine reservoir correction, has clarified the relationship between the interments, and has resolved the previous uncertainty.
