The "Gawain Poet" (/ˈɡɑːweɪn, ˈɡæ-, -wɪn, ɡəˈweɪn/ GA(H)-wayn, -win, gə-WAYN;[1][2] fl. late 14th century), or less commonly the "Pearl Poet",[3] is the name given to the author of Sir Gawain and the Green Knight, an alliterative poem written in 14th-century Middle English. Its author appears also to have written the poems Pearl, Patience, and Cleanness; some scholars suggest the author may also have composed Saint Erkenwald. Save for the last (found in BL-MS Harley 2250), all these works are known from a single surviving manuscript, the British Library holding 'Cotton MS' Nero A.x. This body of work includes some of the most highly-regarded poetry written in Middle English.
The Gawain Poet is unidentified. Various scholars[who?] have suggested that the poem is attributable to a member of the landed Massey family of Cheshire, and in particular John Massey of Cotton. This is not widely accepted, however, and the labels "Pearl Poet" or "Gawain Poet" are still preferred[citation needed].
