works. The manuscript of Gawain is known in academic circles as Cotton Nero A.x., following a naming system used by one of its owners, the 16th century Sir Robert Bruce Cotton, a collector of Medieval English texts. Before the Gawain manuscript came into Cotton's possession, it was in the library of Henry Savile in Yorkshire. Little is known about its previous ownership, and until 1824, when the manuscript was introduced to the academic community in a second edition of Thomas Warton's History, edited by Richard Price, it was almost entirely unknown. Even then, the Gawain poem was not published in its entirety until 1839, which is when it was given its present title. Now held in the British Library, it has been dated to the late 14th century, meaning the poet was a contemporary of Geoffrey Chaucer, author of The Canterbury Tales, though it is unlikely that they ever met, and the Gawain poet's English is considerably different from Chaucer's. The three other works found in the same manuscript as Gawain (commonly known as Pearl, Patience, and Cleanness or Purity) are often considered to be written by the same author. However, the manuscript containing these poems was transcribed by a copyist and not by the original poet. Although nothing explicitly suggests that all four poems are by the same poet, comparative analysis of dialect, verse form, and diction have pointed towards single authorship. What is known today about the poet is general. J.R.R. Tolkien and E.V. Gordon, after reviewing the text's allusions, style, and themes, concluded in 1925: The most commonly suggested candidate for authorship is John Massey of Cotton, Cheshire. He is known to have lived in the dialect region of the Gawain Poet and is thought to have written the poem St. Erkenwald, which some scholars argue bears stylistic similarities to Gawain. St. Erkenwald, however, has been dated by some scholars to a time outside the Gawain Poet's era. Thus, ascribing authorship to John Massey is still controversial and most critics consider the Gawain Poet an unknown. Verse form The 2,530 lines and 101 stanzas that make up Sir Gawain and the Green Knight are written in what linguists call the "Alliterative Revival" style typical of the 14th century. Instead of focusing on a metrical syllabic count and rhyme, the alliterative form of this period usually relied on the agreement of a pair of stressed syllables at the
