Anglo-Saxon Ireland : the evidence of the Martyrology of Tallaght

Internal evidence may yet indicate where the martyrology was first kept in Ireland. Eventually, however, the need for a text of this kind also arose at the recently founded church of Tallaght. And here the text originally Northumbrian but now already replete with additions made at Lindisfarne, at Iona, and no doubt elsewhere, was given more or less its surviving form by the addition of a substantial corpus of entries relating to the churches involved in the so-called anchoritic reform.
