ABSTRACT
Trinity College Dublin MS 1336 (H. 3.17) is a volume made up of various vellum books and fragments, for the most part legal tracts, of differing sizes and written at different times.1 It once belonged to Edward Lhuyd, whose collection of Irish manuscripts came to the Trinity Library as a gift from Sir John Sebright in 1786.2 The sections containing legal texts are unusually elaborate and decorated above the ordinary, with multi-coloured initials of very attractive design.3 The first part at least, containing the Senchas Mar, was, at various times, in the possession of members of the Mac Aodhagain (McEgan) family of legal scholars, from whom it was presumably acquired by An Dubhaltach Mac Firbhisigh, who added a note to it in 1666, at the foot of the first page: ' Dubaitach mac Giolla losa Mhoir mhic an Dubhaltaigh mhic Sémuis Mhic Fhirbisigh Leacain idtir Fhiachrach fear an leabhair si. Anno Christi 1666'. Several other memoranda indicate that other parts were transcribed in Ormond and in Leinster.4
