A tendril of the strange fragrance spiralled up from the great stone block. Kenton felt it caress his face like a coaxing hand.He had been aware of that fragrance-an alien perfume, subtly troubling, evocative of fleeting unfamiliar images, of thought-wisps that were gone before the mind could grasp them-ever since he had unsheathed from its coverings the thing Forsyth, the old archaeologist, had sent him from the sand shrouds of ages-dead Babylon.Once again his eyes measured the block-four feet long, a little more than that in height, a trifle less in width. A faded yellow, its centuries hung about it like a half visible garment. On one face only was there inscription, a dozen parallel lines of archaic cuneiform; carved there, if Forsyth were right in his deductions, in the reign of Sargon of Akkad, sixty centuries ago. The surface of the stone was scarred and pitted and the wedge shaped symbols mutilated, half obliterated.Kenton leaned closer over it, and closer around him wound the scented spirals clinging like scores of tendrils, clinging like little fingers, wistful, supplicating, pleading--Pleading for release! What nonsense was this he was dreaming? Kenton drew himself up. A hammer lay close at hand; he lifted it and struck the block, impatiently.The block answered the blow!It murmured; the murmuring grew louder; louder still, with faint bell tones like distant carillons of jade. The murmurings ceased, now they were only high, sweet chimings; clearer, ever more clear they rang, drawing closer, winging up through endless corridors of time.There was a sharp crackling. The block split. From the break pulsed a radiance as of rosy pearls and with it wave after wave of the fragrance-no longer questing, no longer wistful nor supplicating.Jubilant now! Triumphant!Something was inside the block! Something that had lain hidden there since Sargon of Akkad, six thousand years go!The carillons of jade rang out again. Sharply they pealed, then turned and fled back the endless corridors up which they had come. They died away; and as they died the block collapsed; it disintegrated; it became a swirling, slowly settling cloud of sparkling dust.The cloud whirled, a vortex of glittering mist. It vanished like a curtain plucked away.Where the block had been stood-a ship!It floated high on a base of curving waves cut from lapis lazuli and foam-crested with milky rock crystals. Its hull was of crystal, creamy and faintly luminous. Its prow was shaped like a slender scimitar, bent backward. Under the incurved tip was a cabin whose seaward sides were formed, galleon fashion, by the upward thrust of the bows. Where the hull drew up to form this cabin, a faint flush warmed and cloudy crystal; it deepened as the sides lifted; it gleamed at last with a radiance that turned the cabin into a rosy jewel.In the center of the ship, taking up a third of its length, was a pit; down from the bow to its railed edge sloped a deck of ivory. The deck that sloped similarly from the stern was jet black. Another cabin rested there, larger than that at the bow, but squat and ebon. Both decks continued in wide platforms on each side of the pit. At the middle of the ship the ivory and black decks met with an odd suggestion of contending forces. They did not fade into each other. They ended there abruptly, edge to edge; hostile.
