Royal Irish Academy, MS 23 N 10
The manuscript is highly valuable for its compilation of medieval Irish literature, copied in 1575 at Ballycumin, County Roscommon. The responsible scribes were Aodh, Dubhthach, and Torna, three scholars of the Ó Maolconaire (anglicised: O'Mulconry), a learned family also known for compiling Egerton 1782 (British Library) in 1517.
