23 Q 10

An Leabhar Donn

15th cent. Vellum. 10⅗ × 7⅕ (ff. 35-49: 9⅗ × 6⅗), Ff. 49, bearing a late foliation 1-49, and an unnumbered fragment (see infra). The ms. is a composite one, containing sections of various provenance—e.g. (a) ff. 1—10, (b) 13-29, 35-47, (c) 30-33, (d) 48-49. There is no scribal colophon, and the signatures, etc., in marginalia cannot be regarded as scribal (see infra). To judge by the genealogies, the date of writing should be between the years 1432-41. The reigning Ó Néill is Eogan (1432-56) m Néill Óig m. Néill Móir ; the reigning Ó Conchobhair (Ó Conchobhair Ruadh) is Tadg (1426-41) m. Toirrdelbaig m. Aeda. The ms. is at present bound, and it is consequently impossible to make a definite statement as to the composition of the gatherings. They appear to be constituted as follows : ff. 1-6; 7-10; 11, 12 (single leaves); 13-20; 21-28; 29 (single leaf), 30-33, one leaf excised here; 34 (single leaf); 35-47 (fo. 41 being a single leaf, and ff. 35, 47 detached conjugates remounted on vellum); 48-49. Fo. 7 is very stained. Ff. 35 recto, 47 verso are so darkened that they must have formed the outer leaves of a ms. for a considerable time. The condition of ff. 48 recto, 49 verso suggests that these folios, too, formed the outer leaves of a ms. at one time. There are chasms in the ms. after ff. 29, 33. Blanks are ff. 11 verso, 12 verso, 35 recto, 47 verso, 49 verso. Between ff. 40, 41 is inserted a fragment of ms. bearing genealogical matter. Handwriting in (b) is lined in brown, with marginal prickings. The number of columns vary from one to seven (in the genealogical sections). The zoomorphic capitals which occur are rubricated and ochre has been applied.

The ms. at one time belonged to "Félim Mac lomhair" (see Marginalia). If "Domhnall Albanach" who signs his name on fo. 1, inf. marg. (ibid.), is the scribe of B.M. Egerton 93, we have here an indication of date; the identification however with Domhnall Albanach Ó Troightigh (fl. 1477) has not been proved. Bd. in half-calf, gilt-lettered on spine, "Leabhar Donn." Betham ms. Vol. lxxvi (see flyleaf). A rough list in English of contents stands on a front flyleaf.

Marginalia; illegible or unimportant jottings are omitted here.

11 , inf. marg. Mo chreach ón mo chreach, 1 q. Later hand. Reagent has been used here and on several of the marginalia, infra. Beneath is written in a hand apparently different from that on fo. 2, inf. marg., "Ag so leabar Felim Mic Iomiar."
