It was thus he came to trust in Duessa, a wicked witch, who one day led him to rest by a stream whose waters had the fatal effect of rendering every one who drank of them weak and powerless against all attacks of evil. The knight, then, resting by the stream, drank of its waters, and immediately his strength gave way, his blood ran slow, and a chill struck at the very root of his courage.

While lying in this feeble condition, a dreadful sound was heard, that seemed to shake the earth and cause the trees to tremble. Starting up, the knight began to collect his weapons and to don his armour in great haste. But before he could do so, before he had even got his shield in his hand, a hideous giant, more than three times the height of any mortal man, and so huge that the earth groaned under his weight, came stalking into sight. In his hand the giant Orgoglio bore a gnarled oak torn up from the forest, which he used both as staff and weapon, and when he saw the knight he raised this formidable cudgel and bore down upon him in a fury.

Alas! the Red-cross Knight was little able to sustain the combat. Unarmed, disgraced and inwardly dismayed by the power of the fatal waters, he could hardly wield his single blade.

The giant struck with a force that might overthrow a tower of stone, much more a defenceless man: but the knight watched carefully where the blows fell, and skilfully leapt out of their way, and thus for a time evaded them. But not for long: so furious were the blows that the wind they raised presently overthrew him and flung him stunned upon the ground.

The giant was not slow to see his advantage. He uplifted his powerful arm, and with one stroke would have made an end of his opponent had not Duessa interfered. She besought Orgoglio to spare the life of the Red-cross Knight and take only his liberty: and to this the giant consented on condition that Duessa would become his lady-love. He then raised the knight in his cruel arms and carried him in haste to his strong castle, where he threw him into its darkest dungeon.

Such was the tale the dwarf had to tell.

Una heard him patiently to the end, and strove to master her sorrow, but it only grew stronger the more she contended against it. At length, when the first passion of grief had worn itself out, she rose, and, attended by the dwarf, resolved to find her knight, alive or dead. But ever as she wandered through low dales, and over high hills and among thick woods, her grief broke forth from time to time as if from a wound that had not healed.

After a time Una and her dwarf chanced to meet a very noble-looking knight attended by a single follower.

These were none other than the great and good Prince Arthur and Timias his much loved squire. The armour of the Prince glittered from afar, and on his breast he wore a bauldric beset with precious stones, in the midst of which shone one shaped like a lady's head, which was of wondrous worth and was possessed of magic powers. By the bauldric hung the Prince's sword: its sheath was of ivory curiously wrought. The hilt and the buckle were of burnished gold and the handle was of mother-of-pearl. His helmet was also of gold and had a dragon for its crest: the wings of the dragon spread wide apart, while its head couched close upon the Prince's beaver, and its tail stretched low upon his back, and on the top of all was a tuft of divers coloured hair sprinkled with gold and pearls, and quivering in the sunlight. His shield was closely covered and might not be seen of mortal eyes, for it was made of pure and perfect diamond:—one massive piece cut solid from the rock, and no spear could pierce it nor any sword divide its substance.

And never did Prince Arthur reveal its brightness to any single foe, but if he wished to dismay huge monsters or daunt whole armies, then would he discover its exceeding brightness, and so discomfit them. No magic art or enchanter's word had power over it, and all things that were not what they seemed, faded away before its brightness. By it the Prince could blind the proud, turn men into stones, stones to dust, and dust to nought.
