With a choking gurgle, the guard staggered to his feet. He dropped his sword with a clatter to clutch at the blade buried in his throat. Then he teetered forward and plunged off the platform. Conan had to fend off his falling body to keep from being knocked off the ladder himself. The guard struck the floor of the chamber with a thud. A strangled shriek was cut off by the crunch of a pair of dragon's jaws. From below., sounds of another reptilian feast wafted up.
Breathing hard, Conan hauled himself up to the platform and sat down on the edge with his booted feet dangling. The last hour had seen him through some of the closest calls of an adventurous life.
Some dragons remained at the foot of the ladder, gazing hopefully up at him. Little by little they trailed away. Those that had failed to fill their bellies from the recent windfalls resumed their circle around the bright spot in the center of the floor. Presently, with a whistle and a thump., another mutilated corpse fell down the shaft, to be pounced upon and squabbled over by the scaly reception committee.
Having recovered from his exertions, Conan got up and explored. Behind the platform was a tunnel closed by a bronze grille. Beyond the grille, steps led up into the gloom. The grille opened at Conan's touch. Inside this gate was a large recess in the wall, and in this recess a gigantic bronze wheel was mounted. The spokes projected beyond the rim to form handles, so that it resembled, on a larger scale, one of the tiller wheels that Conan had seen on large Zingaran galleons. The wheel was thick with the green, waxy coating of verdigris. It must have stood there for ages since last being turned.
Conan frowned in thought. His gaze wandered to the huge bronze doors across the chamber, beyond the circle of ghoulishly waiting dragons. Why should those doors have been put there in the first place? They must have cost the folk of Ptahuacan a tremendous lot of labor to install. Presumably, a passage led from the other side of them to the world above. But all they were good for was to loose the horde of dragons upon the citizens. Why should the hierarch wish any such thing?
The answer came to Conan's mind with a snap. The dragons served a double purpose. Not only did they dispose of the remains of the sacrificial victims., but also they served as a last-ditch secret weapon, in case the downtrodden populace should rise in rebellion against the priesthood.
And how were they opened? Conan could not be sure, but his glance strayed back to the ancient bronze wheel.
Out in the square, the sacrifice to Xotli must be taking place. Perhaps it had been going on for hours. The square would be packed with people, with the place of honor, nearest to the dragon gates, reserved for the priestly hierarchy. A glorious plan took form in Conan's brain...
Conan stepped through the grille and confronted the wheel. He drew a deep breath, set his burly shoulders to it, and put a surge of strength behind it. Metal groaned under pressure. Conan's boots slid and grated on the stone floor.
He relaxed, took several deep breaths, and tried again. The sinews writhed across his back and shoulders. Somewhere on the other side of the wall, tortured metal squeaked and groaned. Dust and dislodged particles of dirt pattered down. The wheel moved a fingerbreadth, then a fingerbreadth more, with a shriek of metal forced into motion after aeons of inactivity.
Again Conan strained at the wheel., gripping the spokes so fiercely that it almost seemed as if his white-knuckled fingers would sink into the bronze. He heaved until the blood pounded in his temples and roared in his ears. The wheel lurched and revolved several inches. Within the wall somewhere, ponderous counterweights boomed into motion.
Across the chamber, a crack of light appeared between the valves of the great bronze door.
Another heave, and the motion of the wheel became suddenly easier. From beyond the wall came the growl and rumble of the ancient mechanism, forced into motion after so many quiet centuries.
The crack between the doors widened. With a clank of engaging machinery, the wheel began to spin of its own accord, faster and faster. The valves of the bronze door swung wide on screaming hinges. The dragons, which had been peering and shuffling about uneasily as these unaccustomed noises came to their ears, turned toward the opening doors.
Beyond the doors, a steep ramp led up, then turned sharply out of sight. Light came down from above - good, strong daylight. Conan inferred that another pair of doors at the top of the ramp had opened at the same time. These must be in the base of the pyramid or in one of the buildings surrounding the square.
As Conan, gasping for breath, collapsed over the wheel, the dragons, emitting excited bellows, waddled through the open doors. With claws scraping and slipping on the ramp, they poured up the slope and out of sight. From the dark mouths of the tunnels that opened into the chamber, more dragons appeared, roused from their long slumbers by the noise of the mechanism and the roars of their fellows. These joined the procession up the ramp, until forty-odd of the creatures had passed out of sight on their way to the upper world whence a sudden chorus of horrified shrieks wafted faintly down into the chamber.
Still panting, Conan lay against the bottom of the bronze wheel, waiting for his heart to slow down from its wild pounding and smiling grimly through his stiff, gray beard.
CHAPTER NINETEEN
THE CRYSTAL TALISMAN
The horror from the primal slime lived on
to slake its fiendish lust,
When bright Atlantis fell to dust
beneath the trampling hooves of time.
- The Visions of Epemitreus
As Conan heaved on the great bronze wheel in the passage below the square of the pyramid, a crack appeared in the painted plaster that covered the vertical wall of the bay in the side of the pyramid. The plaster broke into fragments which showered down on the pavement at the feet of the drumming, chanting priests. The bronze doors, which the plaster had masked, groaned and squealed as they swung slowly outwards, even as their mates, the similar doors in the chamber of the dragons below, were opening.
The chant died away to silence as the priests backed away from the opening door valves. They stared at one another; questions flew back and forth. Behind the priests, the thousands of Antillians, from the humble artisans standing in the square to the nobility on the tiers of benches, also shifted uneasily. They stood on tiptoe, peered, and questioned.
On top of the pyramid, the sacrificer paused in the midst of his sacrifices, just as he was about to decardiate the stout foreign ruffian with the graying reddish beard. He leaned over and shouted down a question, which was lost in the gathering hubbub.
A tremendous hiss came from the dark interior behind the opening doors. Out into the sunlight shambled the first of the dragons to reach the top of the ramp - fifty feet of slate-gray scales, waddling briskly on bowed, muscular legs and splayed., long-toed feet. Its raised head swiveled from side to side as its great, green eyes, their pupils contracted to slits by the glare, took in the scene around it. From the tip of its long, crocodilian snout, a yard of pink, forked tongue flicked out.
Screaming, the ranks of the chanting priests broke. The priests fought their way into the crowd of common An-tillians, who in turn surged away from the doors. In the panic push, men and women were thrown down and the life was trampled out of them.
