Having passed the night in this cruel perturbation, the Caliph at daybreak retired to his tent, where, without taking the least sustenance, he continued to doze till the dusk of evening began again to come on.  He then resumed his vigils as before, and persevered in observing them for many nights together.  At length, fatigued with so successless an employment, he sought relief from change.  To this end he sometimes paced with hasty strides across the plain, and, as he wildly gazed at the stars, reproached them with having deceived him; but, lo! on a sudden the clear blue sky appeared streaked over with streams of blood, which reached from the valley even to the city of Samarah.  As this awful phenomenon seemed to touch his tower, Vathek at first thought of re-pairing thither to view it more distinctly, but feeling himself unable to advance, and being overcome with apprehension, he muffled up his face in his robe.

Terrifying as these prodigies were, this impression upon him was no more than momentary, and served only to stimulate his love of the marvellous.  Instead, therefore, of returning to his palace, he persisted in the resolution of abiding where the Indian vanished from his view.  One night, however, while he was walking as usual on the plain, the moon and the stars at once were eclipsed, and a total darkness ensued; the earth trembled beneath him, and a voice came forth, the voice of the Giaour, who, in accents more sonorous than thunder, thus addressed him:  “Wouldest thou devote thyself to me?  Adore then the terrestrial influences, and abjure Mahomet.  On these conditions I will bring thee to the palace of subterranean fire; there shalt thou behold in immense depositories the treasures which the stars have promised thee, and which will be conferred by those Intelligences whom thou shalt thus render propitious.  It was from thence I brought my sabres, and it is there that Soliman Ben Daoud reposes, surrounded by the talismans that control the world.”

The astonished Caliph trembled as he answered, yet in a style that showed him to be no novice in preternatural adventures:  “Where art thou? be present to my eyes; dissipate the gloom that perplexes me, and of which I deem thee the cause; after the many flambeaux I have burnt to discover thee, thou mayst at least grant a glimpse of thy horrible visage.”

“Abjure, then, Mahomet,” replied the Indian, “and promise me full proofs of thy sincerity, otherwise thou shalt never behold me again.”

The unhappy Caliph, instigated by insatiable curiosity, lavished his promises in the utmost profusion.  The sky immediately brightened; and by the light of the planets, which seemed almost to blaze, Vathek beheld the earth open, and at the extremity of a vast black chasm, a portal of ebony, before which stood the Indian, still blacker, holding in his hand a golden key that caused the lock to resound.

“How,” cried Vathek, “can I descend to thee without the certainty of breaking my neck? come, take me, and instantly open the portal.”
