With that came Sir Dinadan, and when he saw Sir Tristram wroth he list not to jape. Lo, said Sir Dinadan, here may a man prove, be a man never so good yet may he have a fall, and he was never so wise but he might be overseen, and he rideth well that never fell. So Sir Tristram was passing wroth, and said to Sir Persides and to Sir Dinadan: I will revenge me. Right so as they stood talking there, there came by Sir Tristram a likely knight riding passing soberly and heavily with a black shield. What knight is that? said Sir Tristram unto Sir Persides. I know him well, said Sir Persides, for his name is Sir Briant of North Wales; so he passed on among other knights of North Wales. And there came in Sir Launcelot du Lake with a shield of the arms of Cornwall, and he sent a squire unto Sir Briant, and required him to joust with him. Well, said Sir Briant, sithen I am required to joust I will do what I may; and there Sir Launcelot smote down Sir Briant from his horse a great fall. And then Sir Tristram marvelled what knight he was that bare the shield of Cornwall. Whatsoever he be, said Sir Dinadan, I warrant you he is of King Ban’s blood, the which be knights of the most noble prowess in the world, for to account so many for so many.
