þe kny3t mad ay god chere
The knight made all with cheer,
and sayde quat schuld I wonde
And said what should I fear?
of destines derf and dere
If fate be foul or fair?
what may mon do bot fonde
What may man do but dare?

A 14th-century poem from an unknown author1 in Middle-English that as a standalone story is one of the best known medieval Arthurian tales. Its a very classic quest format, with a mysterious event propelling the2 knight Gawaine3 into a quest that seems both unfindable and unwinnable.

There are also other tellings of the story - The Greene Knight in rhyme, the very similar story in Sir Gawain and the Carle of Carlisle - and some more distantly similar stories that are attributed to other knights.

It’s not too long, and there’s several readable translations out there. Its fame also means it’s covered by several of the “greats” in medieval poetry translation - Tolkien, Armitage, etc.

It also had a recent film adaptation.

Footnotes

  1. Though often called the Gawain Poet for this piece or the Pearl Poet for another poem also believed to be authored by the same.

  2. Almost always headcannoned as young and uncertain from every case I’ve seen. There’s a few hints this lines up with the text, I think, but I think this emphasis probably says more about how we read it now. The story deals heavily with doubt and it’s really compelling to put ourselves in the shoes of an uncertain and untested knight.

  3. Despite his overwhelming popularity in the Middle Ages, this is probably the main (and even only) way he’s remembered today, when he’s remembered at all.
