Knightly Legends of Wales

Then Arthur and the men of his household prepared to go and seek Owain; and their number was three thousand, besides their attendants. And Kynon, the son of Clydno, acted as their guide. And Arthur came to the castle where Kynon had been before; and when he came there the youths were shooting in the same place, and the yellow man was standing hard by. When the yellow man saw Arthur, he greeted him and invited him to the castle.

And Arthur accepted his invitation, and they entered the castle together. And, great as was the number of his retinue, their presence was scarcely observed in the castle, so vast was its extent. And the maidens rose up to wait on them; and the service of the maidens appeared to them all to excel any attendance they had ever met with; and even the pages who had charge of the horses were no worse served that night than Arthur himself would have been in his own palace.
