THE ANGLO-SAXON RUNIC POEM
Hence oferhyrned, "with great horns," ofer being intensive as in vv. 29, 71, oferceald, oferleof.
þorn, so in all AS. Runic alphabets and in most of the OHG. derivatives (cf. v. Grienberger, Ark. f. n. F. xv. p. 1 ff.). þ was adopted into the AS. book-hand and persisted throughout the ME. period, the last trace of it surviving in the archaistic ye (for the).
The Scandinavian alphabets, however, have þurs (cf. AS. þyrs, a giant), and the Salzburg Codex Gothic thyth, which have no connection with each other or with AS. þorn.Os (Salzb. AS. os) < *ansuz, a god (cf. Jordanes, c. xiii., Gothi…proceres suos, quorum quasi fortuna vincebant, non puros homines, ted Ansis, id est semideos, vocaverunt, and the ON. óss), the name of A in the original alphabet. Cf. A(n)suᵹisalas of the Kragehul lance-shaft. But original a seldom remained in AS., and the character became the English Runic letter for æ (æsc). Accordingly a ligature of A and N was invented to express the ō, which arose from -an- followed by þ or s. Later, when the name of the original letter had become æðel, os was used for o in all cases, whatever might have been their origin.
Os is a common element in AS. personal names, e.g. Oswald, Oswine, etc.; cf. A(n)suᵹisalas above, and its Gen. pl. esa used in the charm wið færstice (G.-W. i. 318)gif hit wære esa gescot oððe hit wære ylfa gescot
oððe hit wære hægtessan gescot, nu ic willan þin helpan.
