And after a while they found it was as Merlin said, for they came by and by upon one of those pathways and entered it and penetrated into the forest. And, lo! within that doleful woodland it was so dark that it appeared as though night-time had fallen, although it was bright daylight beyond the borders thereof, wherefore many of that party were very much afraid. But Merlin ever gave them good cheer and so they went forward upon their way. So, by and by, they came out at last from that place and into the open again, whereat they were greatly rejoiced and took much comfort. [Sidenote: _Merlin and Vivien comes to the Valley of Joyousness._] Now, by this time, the evening had come, very peaceful and tranquil, wonderfully beautiful. And in the centre of the valley was a small lake so smooth and clear, like to crystal, that it appeared like an oval shield of pure silver laid down upon the ground. And all about the margin of the lake were level meadows covered over with an incredible multitude of flowers of divers colors and kinds, very beautiful to behold. When Vivien saw this place she cried unto Merlin, “Master, this is, indeed, a very joyous valley, for I do not believe that the blessed meadows of Paradise are more beautiful than this.” And Merlin said, “Very well; let us go down into it.” So they went down and, as they descended, the night fell apace and the round moon arose into the sky and it was hard to tell whether that valley was the more beautiful in the daytime or whether it was the more beautiful when the moon shone down upon it in that wise. So they all came at last unto the borders of the lake and they perceived that there was neither house nor castle at that place. Now upon this the followers of Merlin murmured amongst themselves, saying, “This enchanter hath brought us hitherward, but how will he now provide for us that we may find a resting-place that may shelter us from the inclement changes of the weather. For the beauty of this spot cannot alone shelter us from rain and storm.” And Merlin overheard their murmurings and he said, “Peace! take ye no trouble upon that matter, for I will very soon provide ye a good resting-place.” Then he said to them, “Stand ye a little distance aside till I show ye what I shall do.” So they withdrew a little, as he commanded them, and he and Vivien remained where they were. And Vivien said, “Master, what wilt thou do?” And Merlin said, “Wait a little and thou shalt see.” Therewith he began a certain very powerful conjuration so that the earth began for to tremble and to shake and an appearance as of a great red dust arose into the air. And in this dust there began to appear sundry shapes and forms, and these shapes and forms arose very high into the air and by and by those who gazed thereon perceived that there was a great structure apparent in the midst of the cloud of red dust.
