In July 2006 the discovery of an early ninth century Psalter, still in its original binding, at Fadden More Bog, north Tipperary, was hailed by Patrick Wallace, Director of the National Museum of Ireland, as the greatest find ever to come from a European bog. Trinity College Dublin, attributed to Pope Gregory, which contains the psalms from 3:7-144:11, the division into ?Three Fifties' is created by the Pater Noster which occurs after Pss. 50 and 100. Looking at the first and last psalms not only within the Psalter as a whole but also within each of the ?Three Fifties' can similarly help us to assess the theological themes of the whole of that division, as Nancy de Claisse-Walford (1997) has demonstrated with respect to the fivefold division of the Psalter.
