James Wilson praises a new translation of Sir Gawain and the Green Knight by John Ridland, calling it a “startling success.”
Most translators have either abandoned the [loose alliterative lines of the original] altogether or tried to replicate its alliterative movement in hopes of conveying its harsh, Germanic energy. Ridland, in contrast, renders the poem in loose iambic heptameter, thereby giving us a form that sounds both native and natural to our ear. He also introduces sporadic and spritely alliteration to preserve a hint of the poem’s exotic roughness.
He offers an excerpt, which you might compare with this translation (from the first stanza of part two):
a year turns full turn, and yields never a like;
the form of its finish foretold full seldom.
For this Yuletide passed by, and the year after,
and each season slips by pursuing another:
after Christmas comes crabbed Lenten time,
that forces on flesh fish and food more simple.
