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 (1392–1452). Henry and Marsh-Michel describe it as follows:

"The sumptuous initials of this book are not more or less servile repetition of twelfth-century work ... the work of the scribe also is dazzling. He plays like a virtuoso with various sizes of script, the larger size having a majestic decorative quality. The contents are no less remarkable; the 'Martyrology of Óengus', the 'Acallam na Senórach' and a dindsenchus. The foliage pattern is probably inspired by foreign models, but is so completely integrated that the borrowing is only realised on second thoughts. The initials are large, bold, and drawn in firm lines and bright colours"

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.
