Book of Fermoy

The Book of Fermoy (Irish: Leabhar Fhear Maí, aka RIA MS 23 E 29 or the Book of Roche, leabhar de Róiste) is a medieval Irish text dated to the 14th to 16th century AD.

[1] The majority of the book consists of a compendium of poems, historical tracts and genealogies related to the medieval Roche family compiled in the 1450s and 1460s.

[2] The book was written in the Irish language in the fifteenth century by several scribes.

[2] James Henthorn Todd acquired the work in 1858 - he suggested the title "Book of Roche" would be equally applicable to the work on account of the large quantity of content relating to the history of the Roche Family of Fermoy; one "David [Mór] son of Maurice son of John Roche" is mentioned in the text as a patron of one set of scribes.

[2] (according to Todd 1868) Contents include "Legend of Mór Mumham", including "Elopement of Ruithcearna with Cuana mac Cailcin" Schedule of rents
