That part of Cornwall which was called the lands of Tintagel formed the kingdom of a prince named Mark, and he owed certain yearly tribute or truage to King Anguish of South Ireland. It befell one day that King Anguish sent a messenger, who came to King Mark as he sat in hall, and said: 'Sir king, my master bids me say that the truage which you owe unto him is unpaid for seven years past, and if it be not paid he will demand of you double the sum.' Now King Mark was a man of a mean and covetous mind, and he loved not to give money. Therefore, to put off the payment for a little while, he made answer thus: 'Tell your master that we will pay him no truage; and if your lord says he will have it, let him send a trusty knight of his land that will fight for his right, and we will find another to do battle with him.' When King Anguish heard the message he was wondrous wroth, and called into him the brother of his queen, Sir Marhaus, a good knight of prowess nobly proved, and, besides, a knight of the Round Table. The king craved of him to go and do battle for the truage due from Mark of Cornwall. 'Sir,' said Sir Marhaus, 'I will gladly go and do battle for you on this saucy king or his knight. I ween ye shall have your truage to the last groat, for I fear not the best knight of the Round Table, unless it be Sir Lancelot, and I doubt not King Mark hath no knight of such worth and prowess as I.' So in all haste Sir Marhaus set forth in a ship, and in a little while cast anchor fast by the shore where, on two high cliffs, the castle of Tintagel frowned upon the sea. When King Mark understood that so noble a knight as Sir Marhaus had come to do battle for the truage, he was full of sorrow, and wept as he looked upon the bags of gold in his treasure-chest. He knew of no knight of his court that durst face Sir Marhaus, and he feared much that he would have to part with his gold. Daily Sir Marhaus sent a message up to the castle gate, demanding payment of the truage, or that a knight should come forth to do battle against him. Then King Mark let make a proclamation through all the lands, that if a knight would fight to save the truage of Cornwall he should fare the better as long as he lived. But the days and weeks went by and no knight came forward. Then Sir Marhaus sent at the last a message which said, that if within a day and a night a champion for King Mark came not forward, he should depart. All that day King Mark was sore and ill of mind and haggard of face, and could never stay still, but was for ever faring with his barons to where he could look down upon the ship of Sir Marhaus, and see the knight waiting in his armour. Late in the afternoon, as the king stood thus, gnawing his nails for rage, and so hot and wrathful that none of his barons dare speak to him, there came two horsemen riding swiftly into the courtyard of the castle, and at the sound of their horses' feet King Mark turned eagerly.
