Then the youth pricked forth upon a dappled grey horse of fours years old with a bridle of linked gold and gold upon his saddle. In his hand he bore two spears of silver with heads of steel; a war horn of ivory was slung over his shoulder, and by his side hung a golden sword. Before him were two brindled, white breasted greyhounds with strong collars of rubies around their necks, and the one that was on the left side bounded across to the right side, and the one on the right to the left, and like two sea swallows sported round him. And his horse cast up four sods with his four hooves, like four swallows in the air about his head, now above, now below. About him was a robe of purple, and an apple of gold was at each corner, and every one of the apples was of the value of 100 cows. And the blades of grass bent not beneath him, so light were his horse's feet as he journeyed toward the gate of Arthur's palace.
