Flann Mainistrech (active c. 1014 to 1056) is well-attested in medieval and early modern Gaelic manuscripts and in early printed works on Irish history as an authority on history and literary tradition. He appears to have been an ecclesiastical scholar, based at Monasterboice (modern Co. Louth, Ireland), but potentially operating within wider ecclesiastical and political networks.
Almost fifty texts or fragments of texts, mostly poems, are at some point attributed to him. Their subject-matter includes the regnal history of early medieval Irish kingdoms, legendary material on Ireland and the Gaels’ more distant past, universal and classical history, hagiography, and genealogical traditions. In addition, various sources are extant that concern Flann Mainistrech as a character. Most imply that he was considered a pre-eminent authority; some go further and provide impressionistic sketches of his scholarship and locate him in certain social or political settings.
