The "Pearl Poet," or the "Gawain Poet," is the name given to the author of Pearl, an alliterative poem written in 14th-century Middle English. Its author appears also to have written the poems Sir Gawain and the Green Knight, Patience, and Cleanness; some scholars suggest the author may also have composed Saint Erkenwald. Save for the latter (found in BL-MS Harley 2250), all these works are known from a single surviving manuscript, the British Library holding Cotton Nero A.x. This body of work includes some of the greatest poetry written in Middle English. The Pearl Poet remains unidentified. Some scholarship has argued to assign the poem to one John Massey, a member of the landed gentry from Cheshire. This attribution of the poems of Cotton Nero A.x is not widely accepted, however, reflected in the ongoing use of the labels "Pearl Poet" or "Gawain Poet."
