§ =15. Theories on the metrical form of the alliterative line.= Notwithstanding their comparative scantiness, the Old High German fragments (_Hildebrandslied_, _Wessobrunner Gebet_, _Muspilli_ and two magical formulae, with a total of some 110 lines) formed the basis of the earliest theories of the laws of the accentuation and general character of the original alliterative line. They were assumed to have preserved the features of the primitive metre, and conclusions were drawn from them as to the typical form of the verse. When examined closely, the Old High German remains (and this is true also of the longer monuments in Old Saxon) are found to differ widely from Old Norse and Old English verse in one respect. While the general and dominating features of the line remain the same, the Old High German and Old Saxon lines are much longer than the Old Norse or Old English lines. In Old Norse or Old English the half line frequently contains no more than four syllables, in marked contrast to Old High German and Old Saxon, where the half line or section is considerably longer.
The first attempt at a theory of the metrical structure of the alliterative line was made by Lachmann. He based his theory on the form of verse created by Otfrid, in imitation of Latin models, which consists of a long line of eight accents, separated by leonine rhyme into two sections each of four accents alternately strong and weak.[17] The laws of the rhyming and strophic verse of Otfrid were applied by Lachmann to the purely alliterative verses of the Old High German _Hildebrandslied_, and this system of scanning was further applied by his followers to the alliterative verse of Old English, the true nature of which was long misunderstood on the Continent. In England itself a sounder view of the native alliterative verse was propounded by Bishop Percy as early as 1765, in his _Essay on the Metre of Pierce Plowman_ published along with his well-known _Reliques of Ancient English Poetry_, not to speak of the earlier writings of G. Gascoigne (1575) and James VI (1585). But the number and authority of some of Lachmann's followers are such that some detailed account of their theories must be given.[18]
