Breasts and buttocks, buttocks and breasts, a young man somewhere is chanting in a cockney accent, as if he were selling flowers on the set of My Fair Lady. Across the way I see a fat junior from my lit seminar sneaking into the crowd of sophomores, belly rocking. He's wearing nothing but a sandwich board that reads free test drive on the front and inquire within on the back. Finally I spot Charlie. He's already made his way to the other side of the circle, where Will Clay, another member of the EMT squad, is wearing a pith helmet flanked with beer cans. Charlie snags it off the top of his head and the two begin chasing each other through the courtyard until I can't see them anymore.

Laughter fades in and out. In the commotion, I feel a hand grab my forearm. Let's go.

Gil yanks me toward the outside of the circle. What now? Paul says.

Gil looks around, spotting proctors at every exit. This way, I tell them.

We near one of the dorm entrances and duck into Holder Hall. A drunk sophomore opens the door to her room and stands there, confused, as if we're the ones who are supposed to greet her. She sizes us up, then raises a bottle of Corona in her hand.

Cheers. She belches, then shuts the door just in time for me to see one of her roommates warming up by the fireplace, wearing nothing but a towel.

Come on, I say.

They follow me up a flight of stairs, where I bang loudly on one of the doors.

What are you doi- Gil begins.

But before he can finish, the door opens and I'm greeted by a pair of great green eyes. The lips below them open faintly at the sight of me. Katie is dressed in a tight Navy T-shirt and a pair of weathered jeans; her auburn hair is pulled back into a short ponytail. Before letting us in, she bursts out laughing.

I knew you'd be here, I say, rubbing my hands. When I step in and hug her, the embrace is warm and welcome.

A birthday suit for my birthday, she says, looking me up and down. Her eyes are glowing. So this is why you didn't call.

As Katie backs into the room I see Paul fixated on the camera in her hand, a Pentax with a telephoto lens almost as long as her forearm.

What's that for? Gil asks when Katie turns to put the camera on a bookshelf.

Taking shots for the Prince she says. Maybe they'll print one this time.

This must be why she's not running. Katie has been trying all year to get a photo on the front page of the Daily Princetonian but the seniority system has worked against her. Now she's turned the tables. Only freshmen and sophomores have rooms in Holder, and hers overlooks the entire courtyard.

Where's Charlie? she asks.

Gil shrugs, staring down through the window. Out there playing grab-ass with Will Clay.

Katie returns to me, still smiling. How long did it take you to plan this?

I falter.

Days, Gil improvises, when I can't think of a way to explain that this whole performance wasn't for her. Maybe a week.

Impressive, Katie says. The weathermen didn't know it would start snowing until this morning.

Hours, Gil revises. Maybe a day.

Her eyes never leave me. So let me guess. You need a change of clothes.

We need three.

Katie retreats to her closet and says, Must be pretty chilly out there. Looks like the cold was starting to get to you guys.

Paul looks at her as if she can't possibly mean what he thinks. Is there a phone I could use? he asks, gathering his wits.

Katie points at a cordless on the desk. I move across the room and press up against her, pushing her into the closet. She tries to shake me off, but when I press too hard, both of us fall onto the rows of shoes, high heels in all the wrong places. It takes a second to untangle ourselves, and I stand up expecting moans from Paul and Gil. But their focus is elsewhere. Paul is in the corner, whispering into the phone, while Gil peers out the window. At first I think Gil's looking for Charlie. Then I see the proctor in his line of sight, speaking into his radio as he approaches.

Hey, Katie, Gil says, we don't need matching outfits here. Anything works.

Relax, she says, coming back with handfuls of clothing on hangers. She lays out three pairs of sweatpants, two T-shirts, and a blue dress shirt I've been missing since March. It's the best I can do on short notice.

We throw ourselves into them. Suddenly, from the entryway downstairs, the hiss of a hand radio cuts the air. The outside door to the building thuds shut.

Paul hangs up the phone. I have to get to the library.

You guys go out the back, Katie says, voice quickening. I'll deal with it.

I take her hand as Gil thanks her for the clothes.

I'll see you later? she says to me, conjuring something in her eyes. It's a look that always comes with a smile now, because she can't believe I still fall for it.

Gil groans and drags me out the door by my arm. As we duck out of the building, I can hear Katie's voice calling down to the proctor.

Officer! Officer! I need your help…

Gil turns back, eyes trained on her room. When he sees the proctor arrive in the crosshairs of Katie's leaded window, his expression lightens. Before long, as we head into the piercing wind, Holder vanishes behind a curtain of snow. Campus is nearly empty as we descend toward Dod, and any residue of the tunnels' heat seems to radiate away, washed off in tiny beads of snow that roll from my cheeks. Paul walks slightly ahead of us, keeping a more purposeful pace. The entire time, he doesn't speak a word.

It was through a book that I met Paul. We probably would've met anyway at Firestone Library, or in a study group, or in one of the literature classes we both took freshman year, so maybe there's nothing special about a book. But when you consider that the one in question was five hundred years old, and that it was the same one my father had been studying before he died, the occasion somehow seems more momentous.

The HypnerotomachiaPoliphili, which in Latin means Poliphilo's Struggle for Love in a Dream, was published around 1499 by a Venetian man named Aldus Manutius. The Hypnerotomachia is an encyclopedia masquerading as a novel, a dissertation on everything from architecture to zoology, written in a style that even a tortoise would find slow. It is the world's longest book about a man having a dream, and it makes Marcel Proust, who wrote the world's longest book about a man eating a piece of cake, look like Ernest Hemingway. I would venture to guess that Renaissance readers felt the same way. The Hypnerotomachia was a dinosaur in its own time. Though Aldus was the greatest printer of his day, the Hypnerotomachia is a tangle of plots and characters connected by nothing but its protagonist, an allegorical everyman named Poliphilo. The gist is simple: Poliphilo has a strange dream in which he searches for the woman he loves. But the way it's told is so complicated that even most Renaissance scholars-the same people who read Plotinus while waiting for the bus-consider the Hypnerotomachia painfully, tediously difficult.

Most, that is, except my father. He marched through Renaissance historical studies to the beat of his own drum, and when the majority of his colleagues turned their backs on the Hypnerotomachia, he squared it in his sights. He'd been converted to the cause by a professor named Dr. McBee, who taught European history at Princeton. McBee, who died the year before I was born, was a mousy man with elephant ears and small teeth who owed all of his success in the world to an effervescent personality and a canny sense of what made history worthwhile. Though he wasn't much to look at, the little man stood tall in the world of the academy. Every year his closing lecture on the death of Michelangelo filled the largest auditorium on campus with spectators and left college men wiping their eyes and reaching for their handkerchiefs. Above all, McBee was a champion of the book that everyone else in his field ignored. He believed there was something peculiar about the Hypnerotomachia, possibly something great, and he convinced his students to search for the old book's true meaning.
