As we gazed away beyond the city, across the sandy desert, the aerial tableaux mirrored above appeared to be the reflection of a flat, black rock of colossal dimensions, rising high and inaccessible like a wall, and descending sheer into dark, deep water, upon the surface of which its gloomy image was reflected as in a mirror. The spot, weird and lonely, was devoid of every vestige of herbage or any living thing, and as I looked upon it in wonderment, impressed by its weirdness, Azala suddenly grasped my arm, exclaiming excitedly,—
“Behold! that black pool! See, it is the Lake of the Accursed! Many times hath its image been revealed unto us in the sky. Remark it carefully, for of a verity am I convinced that in this vision we have a key to the Secret. At that spot must thou search if thou desirest to fathom the mystery.”
My eyes took in every detail of the ineffably dismal picture, the great, inhospitable face of dark granite seemingly so smooth that an eagle could scarce obtain a foothold, its rugged summit with one pointed crag, like a man’s forefinger, pointing higher than the rest towards the dark, lowering clouds that seemed to hang about it, and the Stygian blackness of the stagnant water at its gigantic base. But its sight told me nothing, for it was the reflected image of a scene I had never before gazed upon, a scene so unutterably dismal and dispiriting that I doubted whether any clue could there be found.
Cloud-pictures are of such frequent occurrence at Kano that it is known among the desert tribes as “The City of the Mirage.”
For a few moments the sky remained the mirror of this mystic picture; then gradually it faded into air. When it had entirely disappeared, Azala, uttering no word, drew the curtain again before the lattice as at the same instant Tiamo and the two slaves rose, bowing before their mistress. With quick, impatient gesture she motioned to them to leave, and I, marvelling greatly at the strange religio-magic and extraordinary mirage I had witnessed, followed her through the open curtain and up the stairs back to her own sweetly perfumed apartment.
But in that moment there occurred to me the solemn declaration I had so often heard in the mosque: “Whoso taketh Eblis for his patron beside Allah, shall surely perish with a manifest destruction.”
