Location of ‘Ireland’s Dead Sea Scrolls’ revealed

The exact location of the discovery of what has been dubbed ‘Ireland’s Dead Sea Scrolls’ has been revealed by the National Museum of Ireland.

The Psalter, or Book of Psalms was pulled out of a bog in the townland of Faddan More in north Tipperary, where it was first hidden around 1,000 years ago.

And there's more information on the codex itself:

Archaeologists and conservators from the National Museum spent the last seven days excavating the bog and recovered a few other important pieces.

A fine leather pouch in which the book was kept originally was discovered as well as other small fragments of the manuscript and its cover.

The museum said the investigation results suggest that the owner concealed the book deliberately, perhaps with a view to recovering it at a later date.

All the new material is being conserved and analysed in the National Museum and samples of the peat surrounding the find spot have been sent for specialist analysis.

The extensive fragments of the manuscript appear to be of an Irish Early Christian Psalter, written on vellum. Initial examinations show there are about 45 letters per line and a maximum of 40 lines per page.

The bog has produced other important early medieval artifacts in the past, although nothing this important.
