Sir Gawain and the Green Knight is a great work of medieval literature. The story is considered to be verse romance. There are not many solid facts on the story. The story was composed in the second half of the fourteenth century. It is likely that Sir Gawain and the Green Knight was written around 1375. The author of the piece remains unknown, but we do know of the northwestern dialect of Middle English with which he wrote the poem. The unknown author also consciously wrote in an old-fashioned style. The author is usually referred to as the Gawain poet or the Pearl poet. Three poems were included with Sir Gawain and the Green Knight. "Pearl", "Patience", and "Purity" were all with Sir Gawain and the Green Knight in the same manuscript. This is the reason the author is named as the Pearl poet, in addition to the Gawain poet. All four poems were uniquely named Cotton Nero A.X. This is due to the manuscript's previous owner, Sir Robert Cotton. Cotton supposedly acquired the manuscript from Yorkshire bibliophile Henry Savile (1568-1617), but its whereabouts before then are unknown (Grolier). Sir Gawain and the Green Knight was first edited and published in 1839 by Madden, whose entire name in uncertain. He called the untitled poem Syr Gawayn and the Grene Knyyt. The poem did not receive much attention at all until the beginning of the twentieth century.
