But she spake not the truth, for in her heart she was evil and the heart of Merlin was good, and that which is evil will always hate that which is good. Wherefore, though Vivien lusted for the knowledge of necromancy, and though she spake so lovingly with her lips, yet in her spirit she both feared and hated Merlin because of his wisdom. For she wist right well that, except for the enchantment of that ring which he wore, Merlin would not love her any longer in that wise. Wherefore she said in her heart, “If Merlin teaches me all of his wisdom, then the world cannot contain both him and me.”

Merlin teacheth magic to Vivien.

Now Merlin abided with Vivien in that place for a year and a little more, and in that time he taught her all of magic that he was able to impart. So at the end of that time he said unto her, “Vivien, I have now taught thee so much that I believe there is no one in all of the world who knoweth more than thou dost of these things of magic which thou hast studied in this time. For not only hast thou such power of sorcery that thou canst make the invisible elements take form at thy will, and not only canst thou transform at thy will one thing into the appearance of an altogether different thing, but thou hast such potent magic in thy possession that thou mayst entangle any living soul into the meshes thereof, unless that one hath some very good talisman to defend himself from thy wiles. Nor have I myself very much more power than this that I have given to thee.”

So said Merlin, and Vivien was filled with great joy. And she said in her heart, “Now, Merlin, if I have the good fortune to entangle thee in my spells, then shalt thou never behold the world again.”

Vivien setteth a feast for Merlin.

Now, when the next day had come, Vivien caused a very noble feast to be prepared for herself and Merlin. And by means of the knowledge which Merlin had imparted to her she produced a certain very potent sleeping-potion which was altogether without taste. This potion she herself infused into a certain noble wine, and the wine she poured into a golden chalice of extraordinary beauty.

So when that feast was ended, and whiles she and Merlin sat together, Vivien said, “Master, I have a mind to do thee a great honor.” And Merlin said, “What is it?” “Thou shalt see,” said Vivien. Therewith she smote her hands together and there immediately came a young page unto where they were, and he bare that chalice of wine in his hand and gave it unto Vivien. Then Vivien took the chalice and she went to where Merlin sat and kneeled down before him and said, “Sir, I beseech thee to take this chalice and to drink the wine that is within it. For as that wine is both very noble and very precious, so is thy wisdom both very noble and very precious; and as the wine is contained within a chalice of priceless cost, so is thy wisdom contained within a life that hath been beyond all value to the world.” Therewith she set her lips to the chalice and kissed the wine that was in it.

Then Merlin suspected no evil, but he took the chalice and quaffed of the wine with great cheerfulness.

Merlin is overcome by the wine that Vivien giveth him.

After that, in a little, the fumes of that potent draught began to arise into the brains of Merlin and it was as though a cloud descended upon his sight, and when this came upon him he was presently aware that he was betrayed, wherefore he cried out thrice in a voice, very bitter and full of agony, “Woe! Woe! Woe!” And then he cried out, “I am betrayed!” And therewith he strove to arise from where he sat but he could not.
