King Arthur was at Caerlleon-upon-Usk; and one day he sat in his chamber, and with him were Owain the son of Urien, and Kynon the son of Clydno, and Kai the son of Kyner, and Gwenhwyvar and her handmaidens at needle-work by the window. And if it should be said that there was a porter at Arthur's palace, there was none. Glewlwyd Gavaelvawr was there, acting as porter, to welcome guests and strangers, and to receive them with honor, and to inform them of the manners and customs of the court, and to direct those who came to the hall or to the presence-chamber, and those who came to take up their lodging. In the centre of the chamber King Arthur sat upon a seat of green rushes, over which was spread a covering of flame-colored satin, and a cushion of red satin was under his elbow. Then Arthur spoke. "If I thought you would not disparage me," said he, "I would sleep while I wait for my repast; and you can entertain one another with relating tales, and can obtain a flagon of mead and some meat from Kai." And the king went to sleep. So Kai went to the kitchen and to the mead-cellar, and returned bearing a flagon of mead, and a golden goblet, and a handful of skewers upon which were broiled collops of meat. Then they ate the collops, and began to drink the mead.
