The, so called, 'Annals of Clonmacnoise' are a 17th century translation, into Elizabethan style English, of an Irish chronicle (which shares a common ancestor with the 'Annals of Tigernach'), beginning with the creation and ending in 1408. The translation was completed, by one Connell Mageoghagan, in 1627. The "ould Irish booke" Connell was working from was in poor condition. Some pages were missing, and others completely undecipherable. In the dedication, to his brother (dated 20th April, 1627), he writes that the book: Connell highlights a fate which uninterested owners might allow to befall their old volumes - possibly not one that would spring to the modern mind: Maybe the (presumably, early 15th century) "ould Irish booke" and the original manuscript of Connell's translation ended up as tailors measures, since both are now lost.
