'What is it? What is the matter? Tell me thy sorrow that I may bear it with thee, or, it may be, help thee!' Then the king told her everything that had befallen him, and she stroked his hair the while.
'That is nothing to grieve about,' she said when the tale was finished. 'You have the best wife in Erin, and the best horse in Erin. Only do as I bid you, and all will go well.' And the king suffered himself to be comforted.
He was still sleeping when the queen rose and dressed herself, to make everything ready for her husband's journey, and the first place she went to was the stable, where she fed and watered the shaggy brown horse and put the saddle on it. Most people thought this saddle was of wood, and did not see the little sparkles of gold and silver that were hidden in it. She strapped it lightly on the horse's back, and then led it down before the house, where the king waited.
'Good luck to you and victories in all your battles,' she said, as she kissed him before he mounted. 'I need not be telling you anything. Take the advice of the horse, and see you obey it.'
So he waved his hand and set out on his journey, and the wind was not swifter than the brown horse—no, not even the March wind which raced it, and could not catch it. But the horse never stopped nor looked behind, till in the dark of the night he reached the castle of the king of the oak windows.
'We are at the end of the journey,' said the horse, 'and you will find the Sword of Light in the king's own chamber. If it comes to you without scrape or sound, the token is a good one. At this hour the king is eating his supper, and the room is empty, so none will see you. The sword has a knob at the end, and take heed that when you grasp it, you draw it softly out of its sheath. Now go! I will be under the window!'
Stealthily the young man crept along the passage, pausing now and then to make sure that no man was following him, and entered the king's chamber. A strange white line of light told him where the sword was, and crossing the room on tiptoe, he seized the knob, and drew it slowly out of the sheath. The king could hardly breathe with excitement lest it should make some noise and bring all the people in the castle running to see what was the matter. But the sword slid swiftly and silently along the case till only the point was left touching it. Then a low sound was heard, as of the edge of a knife touching a silver plate, and the king was so startled that he nearly dropped the knob.
'Quick! quick!' cried the horse, and the king scrambled hastily through the small window, and leapt into the saddle.
