"A painter in China once painted a hall;--
Such a web never hung on an emperor's wall;--
One half from his brush with rich colors did run,
The other he touched with a beam of the sun;
So that all which delighted the eye in one side,
The same, point for point, in the other replied.
"In thee, friend, that Tyrian chamber is found;
Thine the star-pointing roof, and the base on the ground:
Is one half depicted with colors less bright?
Beware that the counterpart blazes with light!"
