Belonging to this group are _William of Palerne_, _Joseph of Arimathie_, both belonging to the middle of the fourteenth century, the three editions of William Langland's _Vision concerning Piers Plowman_, of somewhat later date, and a few minor poems. The _Romance of the Chevelere Assigne_, written in the East Midland district, at the end of the fourteenth century, and the works of the Gawain-poet, viz. _Sir Gawain and the Green Knight_, _Cleanness_, _Patience_, and the _Legend of St. Erkenwald_ (Horstmann, _Altengl. Legenden_, 1881, p. 265), form the transition to another group of poems belonging to the North of England, but differing somewhat from the preceding with regard to their metre. The most important amongst these is Langland's great work, but it is at the same time most unequal in respect to its versification. In many passages, especially in the beginning of the several Passus, as they are called, the flow of the verses is very regular; in other passages the theses are frequently of such great length, and the arsis stands out so indistinctly, that the rhythm of the verse can only be made out with difficulty. Some examples taken from the B-text (c. 1377) may serve to illustrate this: Extended second hemistich (Type A): _To =b=óres and to =b=róckes | þat =b=réketh adòwn myne hégges._ vi. 31. _And so I =t=rówe =t=réwly | by þat men =t=élleth of chárite._ xv. 158. _Ac ȝut in =m=ány mo =m=áneres | =m=én offènden þe hóligòste._ xvii. 280. Extended first hemistich (Type A): _=L=éue him nòuȝt, for he is =l=écherous | and =l=íkerous of tónge._ vi. 268. _=L=áboreres þat haue no =l=ánde | to =l=ýue on but her hándes._ ib. 309. _'Now, by þe =p=éril of my soúle!' quod Pieres, | 'I shal a=p=éyre ȝou álle!'_ vi. 173. Such verses obviously contain only two beats in each hemistich, although at the same time some of the syllables forming the thesis may have a somewhat stronger accent than others. For as a rule such extended verses are succeeded by a normal line, clearly bringing out again the general four-beat rhythm, as is the case with the line (A + A) following immediately upon the last-mentioned example: _And =h=óuped after =h=únger | þat =h=érd hym atte fírste._ vi. 174. Type A is in _Piers Plowman_ the usual one, but the types C and BC frequently occur. In the following examples we have type C in the second hemistich: _And hadden =l=éue to =l=ye | al here =l=ýf áfter._ Prol. 49.
