In his fortress-palace at Nankin sat the Emperor Shun-yuen. It was a torrid day of the year 750, and the Emperor was fretful. Surfeit of power, he was reflecting, did not spell content. On the contrary, like lesser surfeits, it discomposed. It was a natural paradox, perhaps, that his seeming so full should make life appear so empty. He could not, for all his omnipotence, both eat his cake and have it.

The Emperor drew his imperial yellow silk surtout querulously about him, and “wah’d” snappishly. What was wrong with everything? As the third or fourth of his dynasty—the Tang, now long matured in a peaceful despotism—he possessed the lordship of all the good that existed. And yet the good was not good enough—it was failing somehow to satisfy. And why? He wished, by the celestial dragon, that he could tell!

Shun-yuen, as the product and successor of warriors, of their kin but not of their kind, was really, had he known it, in the throes of a new birth. There was represented in him at the moment the line of demarcation between the forces of the blood and of the intellect. He stood far enough away from the spirit which had enthroned his dynasty to have developed wholly in the ameliorating atmosphere of the peace which that spirit had won for itself; and yet there survived in him a virility which vaguely aspired to new fields of conquest. Surely there was something yet to be gained from the world beside territory and power; surely to be constituted Emperor of the Sun was not to be condemned to eternal stagnation in its glare? The germ of unrecognised thoughts and aspirations moved in him like a wriggling indigestion.

Suddenly in some near corridor of the Palace there rose a sound of repressed but excited voices, awaking a sympathetic response in his own restlessness. He attributed the disturbance to the general agitation evoked by his condition, since any imperial distress was automatically reflected in the imperial household, which was constituted very much on the lines of a hive; and it was with a thrill of interest, therefore, that he observed the entrance and reverential approach of his Chamberlain Chung-chi, an official of the second rank of the opaque red button and the three peacock feathers in an agate tube.

“Speak,” said the Emperor, ready to chastise for a disappointment, but longing for something novel.

Chung-chi, prostrating himself at the imperial feet, and bowing his forehead nine times to the floor, raised his fat face and obeyed:

“Light of the day, and supreme effulgence, under One, of the entire universe, on whom once to gaze in thy quintessential splendour is to be condemned to perpetual blindness, know that there has been seized in the town a stranger capable of the impossible heresy of asserting that there is on the earth a power greater than the Emperor himself.”

Shun-yuen sat erect, a sudden excitement tingling in his veins.

“Bring this slave before us,” he said, “that we may face and wither him in his blasphemy.”

Chung-chi rose, backed from the presence, disappeared, and returned in a moment, ushering in a man under guard. The stranger, offering no obeisance, stood up calm and fearless before the Emperor.
