Final answer:
The work of the Gawain-Poet, Sir Gawain and the Green Knight, was written in the late 14th century, reflecting the Middle English alliterative tradition. The poem is a part of the Arthurian legend, which was also explored by Alfred Lord Tennyson in The Lady of Shalott.
Step-by-step explanation:
The anonymous Pearl-Poet, also known as the Gawain-Poet, is the unknown author of Sir Gawain and the Green Knight, which is renowned for its alliterative verse. This medieval chivalric romance is estimated to have been written in the late 14th century, specifically between 1375 and 1400. The work belongs to the alliterative tradition preserved during the Middle English period. This literary movement saw the revival of the alliterative verse form that was predominant in the Old English era before the Norman Conquest.
Sir Gawain and the Green Knight forms part of the rich Arthurian legends. These legends include well-known characters like King Arthur, Sir Lancelot, and Camelot, which are referenced in the works of many authors, including Alfred Lord Tennyson in his poem The Lady of Shalott. Tennyson published this poem in 1832, indicating a continued interest and adaptation of Arthurian motifs in English literature.
