Chapter 15 The Chain

The work went on through the night, and the night had no end in it that a man could measure by the stars. They worked in rotations of the ordered kind that Maro set and enforced with the flat of his voice: an hour in the shaft, where the heat came up through the floor and the breath of the mountain moved against the working stones, and an hour in the stair, where the air was no better but the heat was a hand lower, and an hour drawn up in the store chamber with the water and the cracked bread and the dust that had been in the world since the first speaking. The chain ran the whole length of it, hands to hands in the dark, and the stones came up out of the order of the notches and went down into the neck of the throat, each one seating against the last with the clay and ash mortar pressed into the gaps by hands that had never expected to build anything that would outlast them. Caius read the placement from the archive at the head of the stair, and Livia read the breath of the mountain at the rim of the shaft, and between them they set the cadence of the line. The third stone turns a hand's width against the second, so that the master notch of the fourth will seat true. The crack seals from the south face. The clay is packed wet and bakes dry in the heat of the throat, and it will hold what it holds. It was engineering, Corvinus thought, standing in the line with his hands full of the first builders' stone, and it had a cold beauty to it, the beauty of a machine taken up out of the dark after a thousand years and set to work for the exact purpose it had been made for and never served. The bad air came up the stair in the small hours, as Livia had said it would. A man at the head of the line folded without a word, and the line took him out with the practiced reach of men who had done it before, and Caius found the vent the carvings marked above the stair and worked the stopper of it with a crowbar until the foul air moved through, and the work went on. Twice more the line stopped for a man folded on the steps. Twice more the work resumed. It was near the hours of the second watch that the flaw showed itself. The last of the store row had been taken up, and the stones that remained for the closing of the neck were the two that the notches of the archive did not cover, the two that the first builders had cut overlong or the mountain's own movement had warped from true, and they did not seat in the neck the way the line before them had seated. The gap at the south face of the throat would not come shut, and the breath of the mountain came through it in a drawn whistle, higher and thinner than the throat had spoken since the first stone was set. Publius was at the bottom of the line, where he had been since the first stone, planted at the lip of the shaft like a harbor wall, and he looked at the gap with the settled patience of a man who had wedged worse in worse places. "It will take a shim," he said. "The stone will not meet the face of the neck on its own. We cut a wedge of the basalt from the store wall and drive it into the seat, and the overlong stone becomes a true stone." "There is no wedge in the store," Maro said. "The store rows are spent." "Then we take it from the stair," Publius said. "There is a step that is sound, and the soundness is not needed below the seventh riser, and the seventh riser will hold the wall of the throat better empty than it holds us open." He came out of the shaft, and the heat came off him like the heat off a forge, and he took the crowbar back down the passage and worked the block out of the stair that he had marked on the way down. Sextus was in the neck when it happened. The young one had taken the place at the head of the line for the closing, the place that moved the fastest and thought the least, and the chain was passing the overlong stone down to him through the last yard of the shaft when the shim block came in at an angle from the stair, driven by a man working in the dark above the heat and the noise, and the notch of the seating missed its mark by a hand's width that nobody saw. A stone of fifty pounds, delivered in the dark to a seat that had shifted a finger's width, does not whisper about its intention. It speaks. Publius saw it go, saw the angle of the delivery, saw Sextus's shoulders braced under the weight of a thing that had suddenly ceased to be a tool and become a falling slab, and he moved across the neck of the shaft the way a heavy man can move once in a lifetime, when the thing he loves is a hand's breadth from the ground. He took it against the chest, and the breath went out of him in a single sound, and he held the hull of the overlong stone against the face of the neck with the weight of his body and the last of his strength while the chain steadied and the shim was driven and the stone seated true, and only then did the harbor wall of Publius, the once-legionary, the former prisoner, the man who had said he remembered what it meant to be a legionary, go down in the ash of the store floor with his chest caved and the mountain's heat coming up off him like the breath of a forge. They carried him up the stair and the passage and into the deep chamber, and they laid him in the mineral gold where the water ran, and Corvinus knelt beside him with the water skin, and Publius looked at him with a calm that had been in his face since the first week, when the tribune had come to the jail with bread and water and a way out. "I was a legionary again," Publius said. His voice was a whisper, but it was clear. "That's the whole of it. That's all I ever wanted back." He looked at the gold of the mineral walls, which was the lamplight and the mountain, and he was dead before the water reached his lips. Corvinus stayed with him into the grey of the morning, and he wrote the name in the book when the light came, and the garrison buried the once-prisoner on the ridge above the buried town, in the row that was beginning to form there, with the stones of the god's outer work over him. No speech was made. The work was not finished. They went back down the stair. Maro took Publius's place at the bottom of the chain, and the last stone of the store was cut to the measure of the closed neck and driven home, and the clay and ash were packed, and the second mouth of the mountain, which had drawn the breath of the god for a thousand years, was closed to the span of a drawn thread. The silence that came up out of the shaft was the loudest thing Corvinus had heard in his life. The heat was still there, pressing up through the seated stones, but the movement was gone. The mountain no longer breathed through its second mouth. Livia came to the rim of the throat and held her lamp above the sealed neck, and the flame stood straight and tall in the dead-still air, and she looked at it for a long count before she spoke. "It is done," she said. "The work of the first builders is finished. The god has one mouth now, and he will speak through it. We have until the sky burns, and it will not be long. The breath was drawn down to a thread when we closed it. The god has been waiting for this door, Tribune. He has been holding the whole of his breath for it. We go up now, and we bring everyone down into the deep chamber, and we seal the door of the passage behind us, and we wait." The call went up through the passages, and the column began to move down into the warmth of the deep chamber, out of the upper air, down the long slope of the rock-cut way toward the gold of the mineral walls and the sound of the water. And as the last of the column came down and the passage door was barred behind them, the ground began, very gently, in the deep of the world, to shake. The mountain had stopped breathing. And every man who had ever lived at the foot of a mountain knew what the silence meant.
