From The Black Book of Carmarthen
[Arthur]: What man is the porter?
[Glewlwyd]: Glewlwyd Mighty-grip.
Who asks it?
[Arthur]: Arthur and Cei the Fair.[Glewlwyd]: Who comes with you?
[Arthur]: The best men in the world.[Glewlwyd]: To my house you will not come
unless you deliver them.[Arthur]: I shall deliver them
and you will see them.
Wythnaint, Elei,
and Sywyon, these three;
Mabon son of Modron,
servant of Uther Pendragon,
Cystaint son of Banon,
and Gwyn Godybrion;
harsh were my servants
in defending their rights.
Manawydan son of Llyr,
profound was his counsel.
Manawyd carried off
shields pierced and battle-stained.
And Mabon son of Mellt
stained the grass with blood.
And Anwas the Winged
and Lluch of the Striking Hand,
they were defending
on the borders of Eidyn.
A lord would protect them;
my nephew would give them recompense.
Cei would entreat them
as he struck them by threes.
When the grove was lost
cruelty was suffered.
Cei would entreat them
while he cut them down[Cei (?)]: Though Arthur was but playing,
blood was flowing
in the hall of Afarnach
fighting with a hag.
He pierced the cudgel-head

On the mount of Eidyn
they fought Dog-heads;
by the hundred they fell.[Arthur]: They fell by the hundred
before Bedwyr the Fine-sinewed

fierce was his nature
with sword and shield.
Vain was an army
compared to Cei in battle.
He was a sword in battle;
he pledged with his hand.
He was a resolute chieftain
of a host for the country’s good.
Bedwyr and Bridlaw,
nine hundred to listen,
six hundred to disperse
would his attack be worth.
The servants that I had,
it was better when they were alive.
Before the lords of Emrys
I saw Cei in haste;
prince of plunder,
the tall man was hostile.
His revenge was heavy;
his anger was sharp.
When he drank from the buffalo horn
he would drink for four;
when he came into battle
he would strike like a hundred.
Unless it were God who did it.
Cei’s death could not be achieved.
Cei the Fair and Llachau,
they made slaughter
before the pain of the blue-tipped spears.
In the uplands of Ysafngwn
Cei pierced nine witches.
Cei the Fair went to Anglesey
to destroy lions;
his shield was small
against the Clawing Cat.
When people ask
who pierced the Clawing Cat.
(nine score warriors would fall for its food,)
nine score champions
