When King Mark understood that, he let purvey for Sir Tristram a fair vessel, well victualled, and therein was put Sir Tristram, and Gouvernail with him, and Sir Tristram took his harp with him, and so he was put into the sea to sail into Ireland; and so by good fortune he arrived up in Ireland, even fast by a castle where the king and the queen was; and at his arrival he sat and harped in his bed a merry lay, such one heard they never none in Ireland before that time.

And when it was told the king and the queen of such a knight that was such an harper, anon the king sent for him, and let search his wounds, and then asked him his name. Then he answered, I am of the country of Liones, and my name is Tramtrist, that thus was wounded in a battle as I fought for a lady’s right. So God me help, said King Anguish, ye shall have all the help in this land that ye may have here; but I let you wit, in Cornwall I had a great loss as ever had king, for there I lost the best knight of the world; his name was Marhaus, a full noble knight, and Knight of the Table Round; and there he told Sir Tristram wherefore Sir Marhaus was slain. Sir Tristram made semblant as he had been sorry, and better knew he how it was than the king.
