This manuscript is a rare survival, written in the ninth and tenth centuries in Wales. The main text is a Latin poetic retelling of the Gospel narrative by the fourth-century poet Juvencus but around it, in blank spaces and even between the lines, are numerous notes and shorter texts in Old Welsh and Old Irish as well as Latin. In the top margin of this page and two others are some verses in Welsh which are believed to be the oldest surviving physical examples of poetry in Welsh. The manuscript was likely made in Wales, but the main scribe appears to have been Irish. He signed his work with the request, a"Araut dinuadu": "A prayer for Núadu".
