He left the fissure and picked up the spear. This had fallen out when the bird had ripped out the flesh around it. He jabbed threateningly at the eagle, which glared, hissed, and then screamed at him. Wolff shouted back and slowly backed away from the bird. It advanced with short slow steps, rolling slightly. Wolff stopped, yelled again, and jumped at the eagle. Startled, it leaped back and screamed again.

Wolff resumed his cautious retreat, but this time the eagle did not go after him. Only when the curve of the mountain took the predator out of view did Wolff resume climbing. He made sure that there was always a place to dodge into if the bird should come after him. However, no shadow fell on him. Apparently the eagle had wanted only to protect its food.

The middle of the next morning, he came across another gworl. This one had a smashed leg and was sitting with its back against the trunk of a small tree. It brandished a knife at a dozen red and rangy hoglike beasts with hooves like those of mountain goats. These paced back and forth before the crippled gworl and grunted in their throats. Now and then one made a short charge, but stopped a few feet away from the waving knife.

Wolff climbed a boulder and began throwing rocks at the hooved carnivores. A minute later, he wished he had not drawn attention to himself. The beasts clambered up the steep boulder as if stairs had been built for them. Only by rapid thrusting with the spear did he manage to push them back down on the ledge below. The flint tip dug into their tough hides a little but not enough to seriously hurt them.

Squealing, they landed on the rock below, only to scramble back up toward him. Their boar-tusks slashed close to him; a pair almost snipped one of his feet. He was busy trying to keep them from swarming over him when a moment came when all were on the ledge and none on the boulder. He dropped his spear, lifted a rock twice the size of his head, and hurled it down on the back of a boar. The beast screamed and tried to crawl away on its two undamaged front legs. The pack closed in on his paralyzed rear legs and began eating them. When the wounded beast turned to defend himself, he was seized by the throat. In a moment he was dead and being torn apart.

Wolff picked up his spear, climbed down the other side of the rock, and walked to the gworl. He kept an eye upon the feeders, but they did no more than raise their heads briefly to check on him before resuming their tearing at the carcass.

The gworl snarled at Wolff and held its knife ready. Wolff stopped far enough away so that he could dodge if the knife were thrown. A splinter of bone stuck out from the ravaged leg below the knee. The eyes of the gworl, sunk under the pads of cartilage on its low forehead, looked glassy.

Wolff had an unexpected reaction. He had thought that he would at once and savagely kill any gworl he came across. But now he wanted to talk to him. So lonely had he become during the days and nights of climbing that he was glad to speak even to this loathsome creature.

He said, in Greek, "Is there any way in which I can help you?"

The gworl spoke in the back-of-the-throat syllables of its kind and raised the knife. Wolff started walking toward it, then hurled himself to one side as the knife whished by his head. He retrieved the knife, then walked up to the gworl and spoke to him again. The thing grated back, but in a weaker voice. Wolff, bending over to repeat his question, was struck in the face with a mass of saliva.

That triggered off his hate and fear. He rammed the knife into the thick neck; the gworl kicked violently several times and died. Wolff wiped the knife on the dark fur and looked through the leather bag attached to the gworl's belt. It contained dried meat, dried fruit, some dark, hard bread, and a canteen with a fiery liquor. Wolff was not sure about where the meat came from, but he told himself that he was too hungry to be picky. Biting into the bread was an experience; it was almost as hard as stone but, when softened with saliva, tasted like graham crackers.

Wolff kept on climbing. The days and nights passed with no more signs of the gworl. The air was as thick and warm as at sea level, yet he estimated that he must be at least 30,000 feet up. The sea below was a thin silver girdle around the waist of the world.

That night he awakened to feel dozens of small furry hands on his body. He struggled, only to find that the many hands were too strong. They gripped him fast while others tied his hands and feet together with a rope that had a grassy texture. Presently he was lifted high and carried out onto the stone apron before the small cave in which he had slept. The moonlight showed several score bipeds, each about two and a half feet high. They were covered with sleek gray fur, mouselike, but had a white ruff around their necks. The faces were black and pushed in and resembled a bat's. Their ears were enormous and pointed.

Silently, they rushed him over the apron and into another fissure. This opened to reveal a large chamber about thirty feet wide and twenty high. Moonlight bored through a crack in the ceiling and revealed what his nose had already detected, a pile of bones with some rotting flesh. He was set down near the bones while his captors retreated to one corner of the cave. They began talking, or at least twittering, among themselves. One walked over to Wolff, looked at him a moment, and sank onto his knees by Wolff's throat. A second later, he was gnawing at the throat with tiny but very sharp teeth. Others followed him; teeth began chewing all over his body.

It was all done in a literally deadly silence. Even Wolff made no noise beyond his harsh breathing as he struggled. The sharp little pains of the teeth quickly passed, as if some mild anaesthetic were being released into his blood.

He began to feel drowsy. Despite himself, he quit fighting. A pleasant numbness spread through him. It did not seem worthwhile to battle for his life; why not go out pleasantly? At least his death would not be useless. There was something noble in giving his body so that these little beings could fill their bellies and be well-fed and happy for a few days.

A light burst into the cave. Through the warm haze, he saw the batfaces leap away from him and run to the extreme end of the cave, where they cowered together. The light became stronger and was revealed as a torch of burning pine. An old man's face followed the light and bent over him. He had a long white beard, a sunken mouth, a curved sharp nose, and huge supraorbital ridges with bristling eyebrows. A dirty white robe covered his shrunken body. His big-veined hand held a staff on the end of which was a sapphire, large as Wolff's fist, carved in the image of a harpy.

Wolff tried to speak but could only mutter a tangled speech, as if he were coming up out of ether after an operation. The old man gestured with the staff, and several of the batfaces detached themselves from the mass of fur. They scurried sideways across the floor, their slanted eyes turned fearfully toward the old man. Quickly, they untied Wolff. He managed to rise to his feet, but he was so wobbly that the old man had to support him out of the cave.

The ancient spoke in Mycenaean Greek. "You'll feel better soon. The venom does not last long."

"Who are you? Where are you taking me?"

"Out of this danger," the old man said. Wolff

pondered the enigmatic answer. By the time that his mind and body were functioning well again, they had come to another entrance to a cave. They went through a complex of chambers that gradually led them upward. When they had covered about two miles, the old man stopped before a cave with an iron door. He handed the torch to Wolff, pulled the door open, and waved him on in. Wolff entered into a large cavern bright with torches. The door clanged behind him, succeeded by the thud of a bolt shooting fast.
