The Awntyrs off Arthure at the Terne Wathelyn
This is what to terrible W has to say about it (I can't be bothered to type anything myself):
The Awntyrs off Arthure at the Terne Wathelyne (The Adventures of Arthur at Tarn Wadling) is an Arthurian romance of 702 lines written in Middle English alliterative verse. Despite its title, it centres on the deeds of Sir Gawain. The poem, thought to have been composed in Cumberland in the late 14th or early 15th century, survives in four different manuscripts from widely separated areas of England.

Bare was the body and blak to the bone,
Al biclagged in clay uncomly cladde.
Hit waried, hit wayment as a woman,
But on hide ne on huwe no heling hit hadde.
Hit stemered, hit stonayde, hit stode as a stone,
Hit marred, hit memered, hit mused for madde.8
Agayn the grisly goost Sir Gawayn is gone;
He rayked oute at a res, for he was never drad.
Drad was he never, ho so right redes.
On the chef of the cholle,
A pade pikes on the polle,
With eighen holked ful holle
That gloed as the gledes.
Al glowed as a glede the goste there ho glides,
Umbeclipped in a cloude of clethyng unclere,
Serkeled with serpentes all aboute the sides -
To tell the todes theron my tonge wer full tere.9
The burne braides oute the bronde, and the body bides;10
Therefor the chevalrous knight changed no chere.
The houndes highen to the holtes, and her hede hides,
For the grisly goost made a grym bere.
The grete greundes wer agast of the grym bere.
The birdes in the bowes,
That on the goost glowes,
Thei skryke in the skowes
That hatheles may here.
