Durability3

By the side of the caravan road a heavy cross had been planted, and on this grim tree a man hung, nailed there by iron spikes through his hands and feet. Naked but for a loin-cloth, the man was almost a giant in stature, and his muscles stood out in thick corded ridges on limbs and body, which the sun had long ago burned brown. The perspiration of agony beaded his face and his mighty breast, but from under the tangled black mane that fell over his low, broad forehead, his blue eyes blazed with an unquenched fire. Blood oozed sluggishly from the lacerations in his hands and feet.
…
A red lust for vengeance swept away the thought. Curses ebbed fitfully from the man's lips. All his universe contracted, focused, became incorporated in the four iron spikes that held him from life and freedom. His great muscles quivered, knotting like iron cables. With the sweat starting out on his graying skin, he sought to gain leverage, to tear the nails from the wood. It was useless. They had been driven deep. Then he tried to tear his hands off the spikes, and it was not the knifing, abysmal agony that finally caused him to cease his efforts, but the futility of it. The spike-heads were broad and heavy; he could not drag them through the wounds. A surge of helplessness shook the giant, for the first time in his life. He hung motionless, his head resting on his breast, shutting his eyes against the aching glare of the sun.
A beat of wings caused him to look, just as a feathered shadow shot down out of the sky. A keen beak, stabbing at his eyes, cut his cheek, and he jerked his head aside, shutting his eyes involuntarily. He shouted, a croaking, desperate shout of menace, and the vultures swerved away and retreated, frightened by the sound. They resumed their wary circling above his head. Blood trickled over Conan's mouth, and he licked his lips involuntarily, spat at the salty taste.
Thirst assailed him savagely. He had drunk deeply of wine the night before, and no water had touched his lips since before the battle in the square, that dawn. And killing was thirsty, salt-sweaty work. He glared at the distant river as a man in hell glares through the opened grille. He thought of gushing freshets of white water he had breasted, laved to the shoulders in liquid jade. He remembered great horns of foaming ale, jacks of sparkling wine gulped carelessly or spilled on the tavern floor. He bit his lip to keep from bellowing in intolerable anguish as a tortured animal bellows.
The sun sank, a lurid ball in a fiery sea of blood. Against a crimson rampart that banded the horizon the towers of the city floated unreal as a dream. The very sky was tinged with blood to his misted glare. He licked his blackened lips and stared with bloodshot eyes at the distant river. It too seemed crimson with blood, and the shadows crawling up from the east seemed black as ebony.
In his dulled ears sounded the louder beat of wings. Lifting his head he watched with the burning glare of a wolf the shadows wheeling above him. He knew that his shouts would frighten them away no longer. One dipped— dipped—lower and lower. Conan drew his head back as far as he could, waiting with terrible patience. The vulture swept in with a swift roar of wings. Its beak flashed down, ripping the skin on Conan's chin as he jerked his head aside; then before the bird could flash away, Conan's head lunged forward on his mighty neck muscles, and his teeth, snapping like those of a wolf, locked on the bare, wattled neck.
Instantly the vulture exploded into squawking, flapping hysteria. Its thrashing wings blinded the man, and its talons ripped his chest. But grimly he hung on, the muscles starting out in lumps on his jaws. And the scavenger's neck-bones crunched between those powerful teeth. With a spasmodic flutter the bird hung limp. Conan let go, spat blood from his mouth. The other vultures, terrified by the fate of their companion, were in full flight to a distant tree, where they perched like black demons in conclave.
Ferocious triumph surged through Conan's numbed brain. Life beat strongly and savagely through his veins. He could still deal death; he still lived. Every twinge of sensation, even of agony, was a negation of death.
