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.'
