The Book of Fenagh (Irish: Leabar Fidhnacha) is a manuscript of prose and poetry written in Classical Irish by Muirgheas mac Pháidín Ó Maolconaire in the monastery at Fenagh, West Breifne (modern-day County Leitrim).
[2] It later passed to George Michael Conroy, Bishop of Ardagh and Clonmacnoise, for safe-keeping, before his successor Bartholomew Woodlock sold it in 1888 to the Royal Irish Academy (RIA) for £10.
[1] John O'Donovan made a facsimile transcript in 1828, and a manuscript English translation in 1830.
[5] The Irish Manuscripts Commission published a supplementary volume in 1939 with material missing from previous versions.
[8] It was acquired by the National Museum of Ireland the following year, while the manuscript is in the collection of the Royal Irish Academy.
