_on =f=lṓdes ǣ́ht =f=éor gewī́tan._ Beow. 42. In the type A the single alliteration of the first hemistich not unfrequently falls on the second accented syllable, such cases being distinguished, as A3 _þā́ wæs on =b=úrgum =B=ḗowulf Scýldinga._ Beow. 53. In types C and D the single alliteration of the first section must always fall on the first accented syllable which in these types is more emphatic than the second. In types B and E alliteration on the second arsis would bring the alliteration too near to the end of the hemistich, and is therefore rare. Double alliteration in the first hemistich occurs in all of the five types, and chiefly when the two accented syllables have equally strong accents. It is, therefore, least common in C × –́ | –́ × where the first arsis predominates over the second, and is most frequent in the strengthened hemistichs, in D, E, A2, and in the five-membered D* types, where it is the rule.[83] A third form of alliteration, though much less important and frequent than these two, occurs when the second accented syllable of the second hemistich shares in alliteration, in addition to the first accented syllable. There are then two different pairs of alliterative sounds distributed alternately between the two hemistichs. The commonest form of this double alliteration of the whole line is represented by the formula a b | a b, as _hwæt! we =G=ā́r=d=éna in =g=ḗar=d=águm._ Beow. 1. _=Sc=ýldes =é=aferan =Sc=édelandum =í=n._ Beow. 19. _=h=ílde=w=ǣ́þnum ond =h=éaðo=w=ǣ́dum._ Beow. 39; less commonly by the formula a b | b a: _þā =w=ǣ́ron =m=ónige þe his =m=ǣ́g =w=ríðon._ Beow. 2982. _=h=wī́lum for =d=úguðe =d=óhtor =H=rṓðgà̄res._ Beow. 2020; verses corresponding to the formula a a | b b are not found in early poetry. No doubt certain instances of this double alliteration may be accidental, but others seem intentional. The foregoing rules as to alliteration are strictly observed in the early and classic poetry, but in later times certain licences crept in. Three of these may be noticed. (i) The second accented syllable of the second hemistich is allowed to carry the alliteration instead of the first accented syllable, _=l=ā́stas =l=égde oððǽt hē ge=l=ǣ́dde._ Gen. 2536. (ii) Both accented syllables of the second hemistich alliterate with one accented syllable of the first hemistich,[84] _me =s=éndon tṓ þē =s=ǣ́men =s=nélle._ Byrhtnoth 29. (iii) The four accented syllables of the line all alliterate together, _=G=ódwine ond =G=ódwīg =g=ū̀de ne =g=ȳ́mdon._ Byrhtn. 192. In the majority of cases the same alliterative letter is not employed in two successive lines, but we find cases like
