What was the title of J.R.R. Tolkien’s 1925 edition and translation of the medieval poem Sir Gawain?

J.R.R. Tolkien’s 1925 academic edition and translation is titled Sir Gawain and the Green Knight. He prepared it with E. V. Gordon, and the work was published by Oxford University Press.

The medieval poem is a Middle English Arthurian romance in which Sir Gawain accepts a supernatural challenge from the Green Knight. The poem explores courage, courtesy, honesty, temptation, and the pressure of maintaining a chivalric reputation. Tolkien’s scholarship made the difficult Middle English text more accessible to students and general readers.

Tolkien later produced a separate modern English translation with commentary, published after his death in a volume that also included Pearl and Sir Orfeo. This can create confusion between the 1925 scholarly edition and the later standalone translation. The Green Knight poem also influenced Tolkien’s own interest in medieval imagination, though it is not a Middle-earth story.
