The tide moved faster, the draw of piled-up cycles urging it. He emerged upon the plateau, and met the cooler Desert air. His feet went crunching on the "desert-film" that spread its curious dark shiny carpet as far as the eye could reach; it lay everywhere, unswept and smooth as when the feet of vanished civilizations trod its burning surface, then dipped behind the curtains Time pins against the stars. And here the body of the tide set all one way. There was a greater strength of current, draught and suction. He felt the powerful undertow. Deeper masses drew his feet sideways, and he felt the rushing of the central body of the sand. The sands were moving, from their foundation upwards. He went unresistingly with them.

Turning a moment, he looked back at shining little Helouan in the blaze of evening light. The voices reached him very faintly, merged now in a general murmur. Beyond lay the strip of Delta vivid green, the palms, the roofs of Bedrashein, the blue laughter of the Nile with its flocks of curved felucca sails. Further still, rising above the yellow Libyan horizon, gloomed the vast triangles of a dozen Pyramids, cutting their wedge-shaped clefts out of a sky fast crimsoning through a sea of gold. Seen thus, their dignity imposed upon the entire landscape. They towered darkly, symbolic signatures of the ancient Powers that now watched him taking these little steps across their damaged territory.

He gazed a minute, then went on. He saw the big pale face of the moon in the east. Above the ever-silent Thing these giant symbols once interpreted, she rose, grand, effortless, half-terrible as themselves. And, with her, she lifted up this tide of the Desert that drew his feet across the sand to Wadi Hof. A moment later he dipped below the ridge that buried Helouan and Nile and Pyramids from sight. He entered the ancient waters. Time then, in an instant, flowed back behind his footsteps, obliterating every trace. And with it his mind went too. He stepped across the gulf of centuries, moving into the Past. The Desert lay before him—an open tomb wherein his soul should read presently of things long vanished.

The strange half-lights of sunset began to play their witchery then upon the landscape. A purple glow came down upon the Mokattam Hills. Perspective danced its tricks of false, incredible deception. The soaring kites that were a mile away seemed suddenly close, passing in a moment from the size of gnats to birds with a fabulous stretch of wing. Ridges and cliffs rushed close without a hint of warning, and level places sank into declivities and basins that made him trip and stumble. That indescribable quality of the Desert, which makes timid souls avoid the hour of dusk, emerged; it spread everywhere, undisguised. And the bewilderment it brings is no vain, imagined thing, for it distorts vision utterly, and the effect upon the mind when familiar sight goes floundering is the simplest way in the world of dragging the anchor that grips reality. At the hour of sunset this bewilderment comes upon a man with a disconcerting swiftness. It rose now with all this weird rapidity. Henriot found himself enveloped at a moment's notice.

But, knowing well its effect, he tried to judge it and pass on. The other matters, the object of his journey chief of all, he refused to dwell upon with any imagination. Wisely, his mind, while never losing sight of it, declined to admit the exaggeration that over-elaborate thinking brings. "I'm going to witness an incredible experiment in which two enthusiastic religious dreamers believe firmly," he repeated to himself. "I have agreed to draw—anything I see. There may be truth in it, or they may be merely self-suggested vision due to an artificial exaltation of their minds. I'm interested—perhaps against my better judgment. Yet I'll see the adventure out—because I must."

This was the attitude he told himself to take. Whether it was the real one, or merely adopted to warm a cooling courage, he could not tell. The emotions were so complex and warring. His mind, automatically, kept repeating this comforting formula. Deeper than that he could not see to judge. For a man who knew the full content of his thought at such a time would solve some of the oldest psychological problems in the world. Sand had already buried judgment, and with it all attempt to explain the adventure by the standards acceptable to his brain of to-day. He steered subconsciously through a world of dim, huge, half-remembered wonders.

The sun, with that abrupt Egyptian suddenness, was below the horizon now. The pyramid field had swallowed it. Ra, in his golden boat, sailed distant seas beyond the Libyan wilderness. Henriot walked on and on, aware of utter loneliness. He was walking fields of dream, too remote from modern life to recall companionship he once had surely known. How dim it was, how deep and distant, how lost in this sea of an incalculable Past! He walked into the places that are soundless. The soundlessness of ocean, miles below the surface, was about him. He was with One only—this unfathomable, silent thing where nothing breathes or stirs—nothing but sunshine, shadow and the wind-borne sand. Slowly, in front, the moon climbed up the eastern sky, hanging above the silence—silence that ran unbroken across the horizons to where Suez gleamed upon the waters of a sister sea in motion. That moon was glinting now upon the Arabian Mountains by its desolate shores. Southwards stretched the wastes of Upper Egypt a thousand miles to meet the Nubian wilderness. But over all these separate Deserts stirred the soft whisper of the moving sand—deep murmuring message that Life was on the way to unwind Death. The Ka of Egypt, swathed in centuries of sand, hovered beneath the moon towards her ancient tenement.

For the transformation of the Desert now began in earnest. It grew apace. Before he had gone the first two miles of his hour's journey, the twilight caught the rocky hills and twisted them into those monstrous revelations of physiognomies they barely take the trouble to conceal even in the daytime. And, while he well understood the eroding agencies that have produced them, there yet rose in his mind a deeper interpretation lurking just behind their literal meanings. Here, through the motionless surfaces, that nameless thing the Desert ill conceals urged outwards into embryonic form and shape, akin, he almost felt, to those immense deific symbols of Other Life the Egyptians knew and worshipped. Hence, from the Desert, had first come, he felt, the unearthly life they typified in their monstrous figures of granite, evoked in their stately temples, and communed with in the ritual of their Mystery ceremonials.

This "watching" aspect of the Libyan Desert is really natural enough; but it is just the natural, Henriot knew, that brings the deepest revelations. The surface limestones, resisting the erosion, block themselves ominously against the sky, while the softer sand beneath sets them on altared pedestals that define their isolation splendidly. Blunt and unconquerable, these masses now watched him pass between them. The Desert surface formed them, gave them birth. They rose, they saw, they sank down again—waves upon a sea that carried forgotten life up from the depths below. Of forbidding, even menacing type, they somewhere mated with genuine grandeur. Unformed, according to any standard of human or of animal faces, they achieved an air of giant physiognomy which made them terrible. The unwinking stare of eyes—lidless eyes that yet ever succeed in hiding—looked out under well-marked, level eyebrows, suggesting a vision that included the motives and purposes of his very heart. They looked up grandly, understood why he was there, and then—slowly withdrew their mysterious, penetrating gaze.

The strata built them so marvellously up; the heavy, threatening brows; thick lips, curved by the ages into a semblance of cold smiles; jowls drooping into sandy heaps that climbed against the cheeks; protruding jaws, and the suggestion of shoulders just about to lift the entire bodies out of the sandy beds—this host of countenances conveyed a solemnity of expression that seemed everlasting, implacable as Death. Of human signature they bore no trace, nor was comparison possible between their kind and any animal life. They peopled the Desert here. And their smiles, concealed yet just discernible, went broadening with the darkness into a Desert laughter. The silence bore it underground. But Henriot was aware of it. The troop of faces slipped into that single, enormous countenance which is the visage of the Sand. And he saw it everywhere, yet nowhere.
