A better known of a 2 is Nennius, the student of Elvodugus. Elvodugus is ordinarily identified sustaining a bishop Elfoddw of Gwynedd, who convinced a rest of the Welsh part of Celtic Christianity to celebrate Easter on a same date when the more Catholics in Britain in AD 768, and is late stated per Annales Cambriae to have died within 809. This Nennius is traditionally stated when getting sleep in the early 9th century, and is identified around of these class action of manuscripts of the Historia Brittonum as the author of that act. A careful scholarship of professor David N. Dumville on this text has instead shown that the manuscripts that make this claim come from an exemplar dating to the later eleventh century, far later than the exemplars of other versions of this manuscript — as well as over two hundred years after this Nennius is supposed to have lived. But, a total of historiographer however refer to the creator of either the original text of the Historia Brittonum, or even even this specific recension, when Nennius, or pseudo-Nennius.

the more Nemnivus, or even Nennius, is mentioned inside a Welsh manuscript of the ninth century. Inside response to the supercilious accusation of the Saxon scholar that the Britons had no alphabet of their own, this Nemnivus is said to develop invented an alphabet on the fly sequentially to refute this insult. A alphabet Nemnivus is said to keep around invented is preserved in that manuscript, & according to Nora K. Chadwick it is derived from the Old English futhark or runic writing. "Indeed the names given to some of his letters seem to show evidence of an actual knowledge of their Saxon names," Chadwick concludes.

A few conclude that these 2 numbers come a equivalent person. Others argue that drawing such a guide is non warranted, since Nennius, a student of Elvodugus, is arguably fictitious, & since a histories of each Wales & Britainside on top the cycle in wonder come quite uncomplete.
