From the perspective of verse form, the alliterative poetry of the later Middle Ages constitutes a very diverse corpus. The unrhymed poems of the alliterative revival show both continuities and discontinuities with Old English verse, with regard to alliterative patterning as well as rhythmical constraints. The introduction of rhyme created further formal variety, and encouraged alliterative poets to develop anisometric strophes, including bob‐and‐wheel stanzas.
