And the motions that they made, he saw, were definite harmonious patterns their dark figures traced upon the shining valley floor. Like the points of compasses, with stems invisible, and directed from the sky, their movements marked the outlines of great signatures of power—the sigils of the type of life they would evoke. It would come as a Procession. No individual outline could contain it. It needed for its visible expression—many. The descent of a group-soul, known to the worship of this mighty system, rose from its lair of centuries and moved hugely down upon them. The Ka, answering to the summons, would mate with sand. The Desert was its Body.

Yet it was not this that he had come to fix with block and pencil. Not yet was the moment when his skill might be of use. He waited, watched, and listened, while this river of half-remembered things went past him. The patterns grew beneath his eyes like music. Too intricate and prolonged to remember with accuracy later, he understood that they were forms of that root-geometry which lies behind all manifested life. The mould was being traced in outline. Life would presently inform it. And a singing rose from the maze of lines whose beauty was like the beauty of the constellations.

This sound was very faint at first, but grew steadily in volume. Although no echoes, properly speaking, were possible, these precipices caught stray notes that trooped in from the further sandy reaches. The figures certainly were chanting, but their chanting was not all he heard. Other sounds came to his ears from far away, running past him through the air from every side, and from incredible distances, all flocking down into the Wadi bed to join the parent note that summoned them. The Desert was giving voice. And memory, lifting her hood yet higher, showed more of her grey, mysterious face that searched his soul with questions. Had he so soon forgotten that strange union of form and sound which once was known to the evocative rituals of olden days?

Henriot tried patiently to disentangle this desert-music that their intoning voices woke, from the humming of the blood in his own veins. But he succeeded only in part. Sand was already in the air. There was reverberation, rhythm, measure; there was almost the breaking of the stream into great syllables. But was it due, this strange reverberation, to the countless particles of sand meeting in mid-air about him, or—to larger bodies, whose surfaces caught this friction of the sand and threw it back against his ears? The wind, now rising, brought particles that stung his face and hands, and filled his eyes with a minute fine dust that partially veiled the moonlight. But was not something larger, vaster these particles composed now also on the way?

Movement and sound and flying sand thus merged themselves more and more in a single, whirling torrent. But Henriot sought no commonplace explanation of what he witnessed; and here was the proof that all happened in some vestibule of inner experience where the strain of question and answer had no business. One sitting beside him need not have seen anything at all. His host, for instance, from Helouan, need not have been aware. Night screened it; Helouan, as the whole of modern experience, stood in front of the screen. This thing took place behind it. He crouched motionless, watching in some reconstructed ante-chamber of the soul's pre-existence, while the torrent grew into a veritable tempest.

Yet Night remained unshaken; the veil of moonlight did not quiver; the stars dropped their slender golden pillars unobstructed. Calmness reigned everywhere as before. The stupendous representation passed on behind it all.

But the dignity of the little human movements that he watched had become now indescribable. The gestures of the arms and bodies invested themselves with consummate grandeur, as these two strode into the caverns behind manifested life and drew forth symbols that represented vanished Powers. The sound of their chanting voices broke in cadenced fragments against the shores of language. The words Henriot never actually caught, if words they were; yet he understood their purport—these Names of Power to which the type of returning life gave answer as they approached. He remembered fumbling for his drawing materials, with such violence, however, that the pencil snapped in two between his fingers as he touched it. For now, even here, upon the outer fringe of the ceremonial ground, there was a stir of forces that set the very muscles working in him before he had become aware of it....

Then came the moment when his heart leaped against his ribs with a sudden violence that was almost pain, standing a second later still as death. The lines upon the valley floor ceased their maze-like dance. All movement stopped. Sound died away. In the midst of this profound and dreadful silence the sigils lay empty there below him. They waited to be in-formed. For the moment of entrance had come at last. Life was close.

And he understood why this return of life had all along suggested a Procession and could be no mere momentary flash of vision. From such appalling distance did it sweep down towards the present.

Upon this network, then, of splendid lines, at length held rigid, the entire Desert reared itself with walls of curtained sand, that dwarfed the cliffs, the shouldering hills, the very sky. The Desert stood on end. As once before he had dreamed it from his balcony windows, it rose upright, towering, and close against his face. It built sudden ramparts to the stars that chambered the thing he witnessed behind walls no centuries could ever bring down crumbling into dust.
