L. M. Hollander, The Old Norse God Óðr in The Journal of English and Germanic Philology, Vol. 49, No. 3 (Jul., 1950)
Against this theory, Falk raised the objections that the name of Óðr is not instanced in early Old Norse and that any transition Adonis>Óðr would call for etymological justification; also, that the meaning ‘raging, mad’ ill agrees with the character of Baldr. To account, then, for the name of Óðr, Falk calls attention to a passage in Martianus Capella’s (early 5th century) poem De nuptiis Philologie et Mercurii, translated into Old High German by Notker Labeo. There, in the hymn to the sun god, the sun god is celebrated under his various names; last, as Biblius Adon. This is glossed by Notker as Biblius cantans. In other words, Notker interprets Adon as αδων, present participle of Attic αιδω ‘to sing.’ This, Falk surmises, may have been the common medieval interpretation of the name of Adonis; which, then, translated into Old Norse, would be Óðr; which as a noun also signifies ‘song, poetry.’
