Then, after a while, all became quiet and the dust slowly disappeared from the air, and, behold! there was the appearance of a marvellous castle such as no one there had ever beheld before, even in a dream. For the walls thereof were of ultramarine and vermilion and they were embellished and adorned with figures of gold, wherefore that castle showed in the moonlight like as it were a pure vision of great glory. Now Vivien beheld all that Merlin had accomplished and she went unto him and kneeled down upon the ground before him and took his hand and set it to her lips. And while she kneeled thus, she said, “Master, this is assuredly the most wonderful thing in the world. Wilt thou then teach me such magic that I may be able to build a castle like this castle out of the elements?” And Merlin said, “Yea; all this will I teach thee and more besides; for I will teach thee not only how thou mayst create such a structure as this out of invisible things, but will also teach thee how thou mayst, with a single touch of thy wand, dissipate that castle instantly into the air; even as a child, with a stroke of a straw, may dissipate a beautiful shining bubble, which, upon an instant is, and upon another instant is not. And I will teach thee more than that, for I will teach thee how to change and transform a thing into the semblance of a different thing; and I will teach thee spells and charms such as thou didst never hear tell of before.” Then Vivien cried out, “Master, thou art the most wonderful man in all of the world!” And Merlin looked upon Vivien and her face was very beautiful in the moonlight and he loved her a very great deal. Wherefore he smiled upon her and said, “Vivien, dost thou still hate me?” And she said, “Nay, master.” 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.” * * * * * [Sidenote: _Merlin teacheth magic to Vivien._]
