In universal amethyst again.
There, wild cathedrals, with light-splintering spires,
Shone like a dream in the Eternal mind
And changed as earth and sea and heaven must change.
Over them soared a promontory, black
As night, but in the deepening gulf beyond,
Far down in that vast hollow of violet air,
Winding between the huge Plutonian walls,
The semblance of a ruined city lay.
Dungeons flung wide, and palaces brought low,
