 One man known to have appreciated alliterative verse during the time it was still being composed was Robert Thornton, a 15th-century landowner from North Yorkshire.Thornton's efforts in copying these poems, for the use of himself and his family, resulted in the preservation of several valuable works.The first alliterative poem after the "Brut" for which a date can be established is "Wynnere and Wastoure", which from internal evidence is usually dated to around 1352, though the Alexander A and B fragments have been suggested to be as early as 1340.
