“ H. Leo, in 1857, first tried to prove, from the runic letters forming the poet's name (in the three first poems above named) , that Cynewulf was a Northumbrian. He contended that the form should be Cynevôlf, although Dietrich pointed out that wulf, not wolf, is the Northumbrian form. On the assumption that Cynewulf is the author of the ‘Riddles,’ his northern origin is corroborated by the existence in a manuscript at Leyden of a riddle in Northumbrian dialect which is evidently one of the Exeter riddles (both in Sweet, Oldest English Texts, Early English Text Soc., 1885, p. 150) . ”
