Book of the White Earl

The Book of the White Earl is an Irish religious and literary miscellany created circa 1404-1452.
The Book of the White Earl, now Bodleian Laud Misc. MS 610, consists of twelve folios inserted into Leabhar na Rátha, aka The Book of Pottlerath. It was created by Gaelic scribes under the patronage of James Butler, 4th Earl of Ormond. Henry and Marsh-Michel describe it as follows:
Butler is admired for having been strongly Gaelicised. He was an Irish-speaker and seems to have been the very first of the Anglo-Irish lords to appoint a brehon, Domhnall Mac Flannachadha, for his service. Butler granted Mac Flannchadha lands in Tipperary.
