"It matters not," interrupted the priest, impatiently. "It is enough that you are here, and, being a man, you have the privilege of the inner mysteries. And possibly a message may be awaiting you. Come."
He took Constans by the hand and drew him towards the vaulted entrance-way. There was no reasonable opportunity for protest, and before Constans was fully aware of what was happening he had been hurried through the passage and into a large, semi-darkened building that was filled with the rumble and clank of machinery in rapid motion. Constans, having recovered from the first surprise and his eyes becoming accustomed to the obscurity, looked about him with a dawning sense of comprehension.
In the middle of the hall was installed an enormous piece of machinery, a vast cylindrical construction revolving at great speed, and Constans became the more certain of its real nature as he proceeded to examine it in detail. He recalled the illustrations and diagrams that he had been poring over only the day before at the library building, and he was sure that this monster could be nothing else than an electric dynamo, and one of the very largest size, delivering as high as fifteen thousand horse-power of potential energy. But how to account for the chance that had preserved this mightiest of the Old-World forces? What miracle had been wrought to keep this soulless giant in life through so many years of darkness and of silence? Constans felt his head spinning; the consciousness of a fact so tremendous was overwhelming; to save himself he turned away from the dynamo proper and began looking about for the source of its mechanical energy. He found it in an odd-appearing motor, to which the dynamo was connected by the ordinary means of a shaft and belting.
The engine was simple enough in outward construction. All that could be seen was an apparatus consisting of two ten-foot tuning-forks of steel supported on insulated pedestals, and between them a disk of some unknown composition, mounted in a vertical plane and revolving at inconceivable velocity. The power was taken from the shaft of this revolving disk and reduced in speed by means of gear-wheels before being conveyed to the dynamo. The prongs of the big tuning-forks continued to vibrate strongly, and gave out in unison the loud, humming note that had originally attracted Constans's attention. It was undoubtedly, a form of motor whose power was derived from some secret property of vibratory bodies, a recondite subject to which his books alluded but obscurely. Yet in the years immediately preceding the Great Change the principle seems to have been reduced to practical utility. Here was the engine in actual operation, and whatever its source of fuel supply or the ultimate secret of its energy there could be no doubt about its production of power. It moved, it was alive, and Constans gazed upon it with fascinated eyes.
The priest had risen to his feet; he touched Constans lightly on the shoulder.
"The presence chamber," he said, in a whisper. "Come, that you may look upon the face of the Shining One; he will rejoice in knowing that there is left even one faithful in Doom."
He opened a door leading to a room at the left of the main hall and motioned Constans to enter. The door closed behind them and they stood in darkness. Then came the click of a switch-key, and out of the blackness faint lines of radiance appeared, changing slowly to a fiery brightness. And as the lines grew visible they resolved themselves into the semblance of a great and terrible face, the countenance of a man of heroic size with long hair. There was no suggestion of a body, only that majestic head crowned with hyacinthine locks and limned in lambent fire.
Constans felt his knees shaking under him, and involuntarily he prostrated himself; then again he heard the switch click, and the vision faded into nothingness.
There was the sound of a shutter being thrown back, and the daylight streamed in. He rose uncertainly to his feet and looked about him.
It was a small apartment, low-studded, with cement walls and a tiled floor. Near the door and fastened against the wall was a wooden framework, bearing a complicated arrangement of push-buttons and levers. Constans had seen its like pictured in his books, and he instantly conjectured it to be an electrical switch-board, designed to control and direct the current generated by the dynamo. On the opposite wall was suspended a thick sheet of some insulating substance—vulcanite—and fixed upon it was a net-work of wires in whose outlines he could distinguish the lineaments of the fiery face. Now he understood; it was simply a trick, the passing of a strong current of electricity through platinum wires until they became incandescent.
