It was oftenest at this point, that my restless memory recoiled before the impenetrable darkness which forbade it to see further—­to see on to the last evening, to the fatal night.  It was oftenest at this point, that I toiled and struggled back, over and over again, to seek once more the lost events of the End, through the events of the Beginning.  How often my wandering thoughts thus incessantly and desperately traced and retraced their way over their own fever track, I cannot tell:  but there came a time when they suddenly ceased to torment me; when the heavy burden that was on my mind fell off; when a sudden strength and fury possessed me, and I plunged down through a vast darkness into a world whose daylight was all radiant flame.  Giant phantoms mustered by millions, flashing white as lightning in the ruddy air.  They rushed on me with hurricane speed; their wings fanned me with fiery breezes; and the echo of their thunder-music was like the groaning and rending of an earthquake, as they tore me away with them on their whirlwind course.

Away! to a City of Palaces, to measureless halls, and arches, and domes, soaring one above another, till their flashing ruby summits are lost in the burning void, high overhead.  On! through and through these mountain-piles, into countless, limitless corridors, reared on pillars lurid and rosy as molten lava.  Far down the corridors rise visions of flying phantoms, ever at the same distance before us—­their raving voices clanging like the hammers of a thousand forges.  Still on and on; faster and faster, for days, years, centuries together, till there comes, stealing slowly forward to meet us, a shadow—­a vast, stealthy, gliding shadow—­the first darkness that has ever been shed over that world of blazing light!  It comes nearer—­nearer and nearer softly, till it touches the front ranks of our phantom troop.  Then in an instant, our rushing progress is checked:  the thunder-music of our wild march stops; the raving voices of the spectres ahead, cease; a horror of blank stillness is all about us—­and as the shadow creeps onward and onward, until we are enveloped in it from front to rear, we shiver with icy cold under the fiery air and amid the lurid lava pillars which hem us in on either side.

A silence, like no silence ever known on earth; a darkening of the shadow, blacker than the blackest night in the thickest wood—­a pause—­then, a sound as of the heavy air being cleft asunder; and then, an apparition of two figures coming on out of the shadow—­two monsters stretching forth their gnarled yellow talons to grasp at us; leaving on their track a green decay, oozing and shining with a sickly light.  Beyond and around me, as I stood in the midst of them, the phantom troop dropped into formless masses, while the monsters advanced.  They came close to me; and I alone, of all the myriads around, changed not at their approach.  Each laid a talon on my shoulder—­each raised a veil which was one hideous net-work of twining worms.  I saw through the ghastly corruption of their faces the look that told me who they were—­the monstrous iniquities incarnate in monstrous forms; the fiend-souls made visible in fiend-shapes—­Margaret and Mannion!
