as if it could hold the whole of the ocean. We were led through a small wooden door, then up a narrow spiraling staircase whose stone steps seemed numberless. Finally the staircase opened onto the roof, which was heavily slanted, an inverted V enclosed by stone parapets. The wind was gusting, rolling clouds across the sky; the view was spectacular, the city miniaturized, utterly dwarfed by the chapel. I forgot myself and climbed the slope, then walked along the ridge, letting the wind take me as I stared out at the expanse of crooked streets and stone courtyards.
“You’re not afraid of falling,” a voice said. I turned. It was Dr. Kerry. He had followed me, but he seemed unsteady on his feet, nearly pitching with every rush of wind.
“We can go down,” I said. I ran down the ridge to the flat walkway near the buttress. Again Dr. Kerry followed but his steps were strange. Rather than walk facing forward, he rotated his body and moved sideways, like a crab. The wind continued its attack. I offered him an arm for the last few steps, so unsteady did he seem, and he took it.
“I meant it as an observation,” he said when we’d made it down. “Here you stand, upright, hands in your pockets.” He gestured toward the other students. “See how they hunch? How they cling to the wall?” He was right. A few were venturing onto the ridge but they did so cautiously, taking the same ungainly side steps Dr. Kerry had, tipping and swaying in the wind; everyone else was holding tightly to the stone parapet, knees bent, backs arched, as if unsure whether to walk or crawl.
I raised my hand and gripped the wall.
“You don’t need to do that,” he said. “It’s not a criticism.”
He paused, as if unsure he should say more. “Everyone has undergone a change,” he said. “The other students were relaxed until we came to this height. Now they are uncomfortable, on edge. You seem to have made the opposite journey. This is the first time I’ve seen you at home in yourself. It’s in the way you move: it’s as if you’ve been on this roof all your life.”
A gust of wind swept over the parapet and Dr. Kerry teetered, clutching the wall. I stepped up onto the ridge so he could flatten himself against the buttress. He stared at me, waiting for an explanation.
“I’ve roofed my share of hay sheds,” I said finally.
“So your legs are stronger? Is that why you can stand in this wind?”
I had to think before I could answer. “I can stand in this wind, because I’m not trying to stand in it,” I said. “The wind is just wind. You could withstand these gusts on the ground, so you can withstand them in the air. There is no difference. Except the difference you make in your head.”
He stared at me blankly. He hadn’t understood.
“I’m just standing,” I said. “You are all trying to compensate, to get your bodies lower because the height scares you. But the crouching and the sidestepping are not natural. You’ve made yourselves vulnerable. If you could just control your panic, this wind would be nothing.”
“The way it is nothing to you,” he said.

I WANTED THE MIND of a scholar, but it seemed that Dr. Kerry saw in me the mind of a roofer. The other students belonged in a library; I belonged in a crane.
The first week passed in a blur of lectures. In the second week, every student was assigned a supervisor to guide their research. My supervisor, I learned, was the eminent Professor Jonathan Steinberg, a former vice-master of a Cambridge college, who was much celebrated for his writings on the Holocaust.
My first meeting with Professor Steinberg took place a few days later. I waited at the porter’s lodge until a thin man appeared and, producing a set of heavy keys, unlocked a wooden door set into the stone. I followed him up a spiral staircase and into the clock tower itself, where there was a well-lit room with simple furnishings: two chairs and a wooden table.
I could hear the blood pounding behind my ears as I sat down. Professor Steinberg was in his seventies but I would not have described him as an old man. He was lithe, and his eyes moved about the room with probing energy. His speech was measured and fluid.
“I am Professor Steinberg,” he said. “What would you like to read?”
I mumbled
