The Book of Fermoy (Irish : Leabhar Fhear Maí, aka RIA MS 23 or the Book of Roche, leabhar de Róiste) is a medieval Irish text dated to the 14th to 16th century AD. [1]



The book was written in the Irish language in the fifteenth century by several scribes. The 238 pages contain numerous tales, histories, and biographies. [1] 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.
