“HEREIN doth the adventure tell of a knight who was named Morien. Some of the books give us to wit that he was Perceval's son, and some say that he was son to Agloval, who was Perceval's brother, so that be was nephew unto that good knight. Now we find it written for a truth that Perceval and Galahad alike died virgin knights in the quest of the Holy Grail; and for that cause I say of Perceval that in sooth he was not Morien's father, but that rather was Morien his brother's son. And of a Moorish princess was he begotten at that time when Agloval sought far and wide for Lancelot, who was lost, as ye have read here afore.
I ween that he who made the tale of Lancelot and set it in rhyme forgat, and was heedless of, the fair adventure of Morien. I marvel much that they who were skilled in verse and the making of rhymes did not bring the story to its rightful ending...”
“...He was all black, even as I tell ye: his head, his body, and his hands were all black, saving only his teeth. His shield and his armour were even those of a Moor, and black as a raven.”
Morien translated by JESSIE WESTON
