Leabhar Mór Leacain / The Book of Lecan

RIA MS 23 P 2: Cat. No. 535 Late 14th century - early 15th century (A.D. 1397-A.D. 1418) Vellum: 32cm x 22cm 311 folios (9 in MS 1319 [formerly H.2.17] in the Sebright Collection in Trinity College, Dublin)

Written in Irish mainly by Giolla Íosa Mac Firbisigh, assisted by Adam Ó Cuirnín and Murchad Riabach Ó Cuindlis, at Lecan (Castleforbes), Co. Sligo, under the patronage of the O’Dowds. It contains a large amount of genealogical material, especially relating to the families with which the Mac Firbisigh were associated, as well as historical, biblical and hagiographical material. Included are a Dindshenchas, Bansenchas, and versions of Lebor Gabála, Uraicept an nÉces, Cóir Anmann, and Book of Rights.

The writing is in double columns and the main and minor headings and hundreds of capital letters are decorated and coloured in vivid vermilion and yellow.

In 1612 the manuscript was in the hands of Henry Perse, who numbered the leaves, and in 1636 it was seen by Míchéal Ó Cléirigh. It was part of Archbishop James Ussher’s library and was in Trinity College, Dublin in 1686 but was appropriated by Sir John Fitzgerald during James II’s occupation of Dublin in 1698. It was removed to France and through the efforts of General Charles Vallancey the manuscript was presented in 1787 to the Royal Irish Academy by Abbé Kearney, Superior of the Irish College at Paris.

In 1968 cleaning, repair and rebinding were done by Roger Powell, at a cost of £475Stg. The 19th-century, dark green, tooled-leather cover with the stamp ‘Geo. Mullen Dublin 1831’ was removed. The leaves were relaxed with water and flattened, unnecessary patches removed and mends made with parchment and transparent vellum. It was resewn in a zig-zag of hand-made paper on seven double cords and bound in English oak. The spine was covered with alum-tawed pigskin and it is kept under slight pressure in an oak case, specially designed by Edward Barnsley.
