Here he was not pursued by the demon spiders. But, hurrying on lest they or the mummy overtake him, he was soon halted by the rim of a great pit which filled the catacomb from wall to wall and was overwide for the leaping of man. The dog Ansarath, sniffing certain odors that arose from the pit, recoiled with a mad howling; and Nushain, holding the taper outstretched above it, discerned far down a glimmer of ripples spreading circle-wise on some unctuous black fluid; and two blood-red spots appeared to swim with a weaving motion at the center. Then he heard a hissing as of some great cauldron heated by wizard fires; and it seemed that the blackness boiled upward, mounting swiftly and evilly to overflow the pit; and the red spots, as they neared him, were like luminous eyes that gazed malignantly into his own….
So Nushain turned away in haste; and, returning upon his steps, he found the mummy awaiting him at the junction of the catacombs.
“It would seem, O Nushain, that you have doubted your own horoscope,” said the guide, with a certain irony. “However, even a bad astrologer, on occasion, may read the heavens aright. Obey, then, the stars that decreed your journey.”
Henceforward, Nushain followed the mummy without recalcitrance. Returning to the chamber in which stood the immense sarcophagus, he was enjoined by his guide to replace in its socket the black taper he had stolen. Without other light than the phosphorescence of the mummy’s cerements, he threaded the foul gloom of those profounder ossuaries which lay beyond. At last, through caverns where a dull dawning intruded upon the shadows, he came out beneath shrouded heavens, on the shore of a wild sea that clamored in mist and cloud and spindrift. As if recoiling from the harsh air and light, the mummy drew back into the subterrane, and it said:
“Here my dominion ends, and I must leave you to await the second guide.”
Standing with the poignant sea-salt in his nostrils, with his hair and garments outblown on the gale, Nushain heard a metallic clangor, and saw that a door of rusty bronze had closed in the cavern-entrance. The beach was walled by unscalable cliffs that ran sheerly to the wave on each hand. So perforce the astrologer waited; and from the torn surf he beheld erelong the emergence of a sea-blue merman whose head was half human, half apish; and behind the merman there hove a small black barge that was not steered or rowed by any visible being. At this, Nushain recalled the hieroglyphs of the sea-creature and the boat which had appeared on the margin of his nativity; and unrolling the papyrus, he saw with wonderment that the figures were both gone; and he doubted not that they had passed, like the mummy’s hieroglyph, through all the zodiacal Houses, even to that House which presided over his destiny; and thence, mayhap, they had emerged into material being. But in their stead now was the burning hieroglyph of a fire-colored salamander, set opposite to the Great Dog.
The merman beckoned to him with antic gestures, grinning deeply, and showing the white serrations of his shark-like teeth. Nushain went forward and entered the barge in obedience to the signs made by the sea-creature; and Mouzda and Ansarath, in faithfulness to their master, accompanied him. Thereupon the merman swam away through the boiling surf; and the barge, as if oared and ruddered by mere enchantment, swung about forthwith, and warring smoothly against wind and wave, was drawn straightly over that dim, unnamable ocean.
Half-seen amid rushing foam and mist, the merman swam steadily on before. Time and space were surely outpassed during that voyage; and as if he had gone beyond mortal existence, Nushain experienced neither thirst nor hunger. But it seemed that his soul drifted upon seas of strange doubt and direst alienation; and he feared the misty chaos about him even as he had feared the nighted catacombs. Often he tried to question the mer-creature concerning their destination, but received no answer. And the wind blowing from shores unguessed, and the tide flowing to unknown gulfs, were alike filled with whispers of awe and terror.
Nushain pondered the mysteries of his journey almost to madness; and the thought came to him that, after passing through the region of death, he was now traversing the grey limbo of uncreated things; and, thinking this, he was loath to surmise the third stage of his journey; and he dared not reflect upon the nature of its goal.
Anon, suddenly, the mists were riven, and a cataract of golden rays poured down from a high-seated sun. Near at hand, to the lee of the driving barge, a tall island hove with verdurous trees and light, shell-shaped domes, and blossomy gardens hanging far up in the dazzlement of noon. There, with a sleepy purling, the surf was lulled on a low, grassy shore that had not known the anger of storm; and fruited vines and full-blown flowers were pendent above the water. It seemed that a spell of oblivion and slumber was shed from the island, and that any who landed thereon would dwell inviolable forever in sun-bright dreams. Nushain was seized with a longing for its green, bowery refuge; and he wished to voyage no further into the dreadful nothingness of the mist-bound ocean. And between his longing and his terror, he quite forgot the terms of that destiny which had been ordained for him by the stars.
There was no halting nor swerving of the barge; but it drew still nearer to the isle in its coasting; and Nushain saw that the intervening water was clear and shallow, so that a tall man might easily wade to the beach. He sprang into the sea, holding his horoscope aloft, and began to walk toward the island; and Mouzda and Ansarath followed him, swimming side by side.
Though hampered somewhat by his long wet robes, the astrologer thought to reach that alluring shore; nor was there any movement on the part of the merman to intercept him. The water was midway between his waist and his armpits; and now it lapped at his girdle; and now at the knee-folds of his garment; and the island vines and blossoms drooped fragrantly above him.
Then, being but a step from that enchanted beach, he heard a great hissing, and saw that the vines, the boughs, the flowers, the very grasses, were intertwined and mingled with a million serpents, writhing endlessly to and fro in hideous agitation. From all parts of that lofty island the hissing came, and the serpents, with foully mottled volumes, coiled, crept and slithered upon it everywhere; and no single yard of its surface was free from their defilement, or clear for human treading.
Turning seaward in his revulsion, Nushain found the merman and the barge waiting close at hand. Hopelessly he re-entered the barge with his followers, and the magically driven boat resumed its course. And now, for the first time, the merman spoke, saying over his shoulder in a harsh, half-articulate voice, not without irony: “It would seem, O Nushain, that you lack faith in your own divinations. However, even the poorest of astrologers may sometimes cast a horoscope correctly. Cease, then, to rebel against that which the stars have written.”
The barge drove on, and the mists closed heavily about it, and the noon-bright island was lost to view. After a vague interim the muffled sun went down behind inchoate waters and clouds; and a darkness as of primal night lay everywhere. Presently, through the torn rack, Nushain beheld a strange heaven whose signs and planets he could not recognize; and at this there came upon him the black horror of utmost dereliction. Then the mists and clouds returned, veiling that unknown sky from his scrutiny. And he could discern nothing but the merman, who was visible by a wan phosphor that clung always about him in his swimming.
Still the barge drove on; and in time it seemed that a red morning rose stifled and conflagrant behind the mists. The boat entered the broadening light, and Nushain, who had thought to behold the sun once more, was dazzled by a strange shore where flames towered in a high unbroken wall, feeding perpetually, to all appearances, on bare sand and rock. With a mighty leaping and a roar as of blown surf the flames went up, and a heat like that of many furnaces smote far on the sea. Swiftly the barge neared the shore; and the merman, with uncouth gestures of farewell, dived and disappeared under the waters.
