The Swerve (3 page)

Though most evident in works of art, the change from one way of perceiving and living in the world to another was not restricted to aesthetics: it helps to account for the intellectual daring of Copernicus and Vesalius, Giordano Bruno and William Harvey, Hobbes and Spinoza. The transformation was not sudden or once-for-all, but it became increasingly possible to turn away from a preoccupation with angels and demons and immaterial causes and to focus instead on things in this world; to understand that humans are made of the same stuff as everything else and are part of the natural order; to conduct
experiments
without fearing that one is infringing on God’s jealously guarded secrets; to question authorities and challenge received doctrines; to legitimate the pursuit of pleasure and the avoidance of pain; to imagine that there are other worlds beside the one that we inhabit; to entertain the thought that the sun is only one star in an infinite universe; to live an ethical life without reference to postmortem rewards and punishments; to contemplate without trembling the death of the soul. In short, it became possible—never easy, but possible—in the poet Auden’s phrase to find the mortal world enough.

There is no single explanation for the emergence of the Renaissance and the release of the forces that have shaped our own world. But I have tried in this book to tell a little known but exemplary Renaissance story, the story of Poggio Bracciolini’s recovery of
On the Nature of Things
. The recovery has the virtue of being true to the term that we use to gesture toward the cultural shift at the origins of modern life and thought: a re-naissance, a rebirth, of antiquity. One poem by itself was certainly not responsible for an entire intellectual, moral, and social transformation—no single work was, let alone one that for centuries could not without danger be spoken about freely in public. But this particular ancient book, suddenly returning to view, made a difference.

This is a story then of how the world swerved in a new direction. The agent of change was not a revolution, an implacable army at the gates, or landfall on an unknown continent. For events of this magnitude, historians and artists have given the popular imagination memorable images: the fall of the Bastille, the Sack of Rome, or the moment when the ragged seamen from the Spanish ships planted their flag in the New World. These emblems of world-historic change can be deceptive—the Bastille had almost no prisoners; Attila’s army quickly withdrew from the imperial capital; and, in the Americas, the truly
fateful
action was not the unfurling of a banner but the first time that an ill and infectious Spanish sailor, surrounded by wondering natives, sneezed or coughed. Still, we can in such cases at least cling to the vivid symbol. But the epochal change with which this book is concerned—though it has affected all of our lives—is not so easily associated with a dramatic image.

When it occurred, nearly six hundred years ago, the key moment was muffled and almost invisible, tucked away behind walls in a remote place. There were no heroic gestures, no observers keenly recording the great event for posterity, no signs in heaven or on earth that everything had changed forever. A short, genial, cannily alert man in his late thirties reached out one day, took a very old manuscript off a library shelf, saw with excitement what he had discovered, and ordered that it be copied. That was all; but it was enough.

The finder of the manuscript could not, of course, have fully grasped the implications of its vision or anticipated its influence, which took centuries to unfold. Indeed, if he had had an intimation of the forces he was unleashing, he might have thought twice about drawing so explosive a work out of the darkness in which it slept. The work that the man held in his hands had been laboriously copied by hand for centuries, but it had long rested uncirculated and perhaps uncomprehended even by the solitary souls who copied it. For many generations, no one spoke of it at all. Between the fourth and the ninth centuries, it was cited fleetingly in lists of grammatical and lexicographical examples, that is, as a quarry of correct Latin usage. In the seventh century Isidore of Seville, compiling a vast encyclopedia, used it as an authority on meteorology. It surfaced again briefly, in the time of Charlemagne, when there was a crucial burst of interest in ancient books and a scholarly Irish monk named Dungal carefully corrected a copy. But, neither debated nor disseminated, after each of these fugitive appearances
it
seemed to sink again beneath the waves. Then, after lying dormant and forgotten for more than a thousand years, it returned to circulation.

The person responsible for this momentous return, Poggio Bracciolini, was an avid letter writer.
³
He penned an account of the event to a friend back in his native Italy, but the letter has been lost. Still, it is possible, on the basis of other letters, both his own and those of his circle, to reconstruct how it came about. For though this particular manuscript would turn out from our perspective to be his greatest find, it was by no means his only one, and it was no accident. Poggio Bracciolini was a book hunter, perhaps the greatest in an age obsessed with ferreting out and recovering the heritage of the ancient world.

The finding of a lost book does not ordinarily figure as a thrilling event, but behind that one moment was the arrest and imprisonment of a pope, the burning of heretics, and a great culturewide explosion of interest in pagan antiquity. The act of discovery fulfilled the life’s passion of a brilliant book hunter. And that book hunter, without ever intending or realizing it, became a midwife to modernity.

IN THE WINTER
of 1417, Poggio Bracciolini rode through the wooded hills and valleys of southern Germany toward his distant destination, a monastery reputed to have a cache of old manuscripts. As must have been immediately apparent to the villagers looking out at him from the doors of their huts, the man was a stranger. Slight of build
¹
and clean-shaven, he would probably have been modestly dressed in a well-made but simple tunic and cloak. That he was not country-bred was clear, and yet he did not resemble any of the city and court dwellers whom the locals would have been accustomed to glimpse from time to time. Unarmed and unprotected by a clanging suit of armor, he was certainly not a Teutonic knight—one stout blow from a raw-boned yokel’s club would have easily felled him. Though he did not seem to be poor, he had none of the familiar signs of wealth and status: he was not a courtier, with gorgeous clothes and perfumed hair worn in long lovelocks, nor was he a nobleman out hunting and hawking. And, as was plain from his clothes and the cut of his hair, he was not a priest or a monk.

Southern Germany at the time was prosperous. The catastrophic Thirty Years’ War that would ravage the countryside and shatter whole cities in the region lay far in the future, as did the horrors of our own time that destroyed much of what had
survived
from this period. In addition to knights, courtiers, and nobles, other men of substance busily traveled the rutted, hard-packed roads. Ravensburg, near Constance, was involved in the linen trade and had recently begun to produce paper. Ulm, on the left bank of the Danube, was a flourishing center of manufacture and commerce, as were Heidenheim, Aalen, beautiful Rothenburg ob der Tauber, and still more beautiful Würzburg. Burghers, wool brokers, leather and cloth merchants, vintners and brewers, craftsmen and their apprentices, as well as diplomats, bankers, and tax collectors, all were familiar sights. But Poggio still did not fit.

There were less prosperous figures too—journeymen, tinkers, knife-sharpeners, and others whose trades kept them on the move; pilgrims on their way to shrines where they could worship in the presence of a fragment of a saint’s bone or a drop of sacred blood; jugglers, fortune-tellers, hawkers, acrobats and mimes traveling from village to village; runaways, vagabonds, and petty thieves. And there were the Jews, with the conical hats and the yellow badges that the Christian authorities forced them to wear, so that they could be easily identified as objects of contempt and hatred. Poggio was certainly none of these.

To those who watched him pass, he must in fact have been a baffling figure. Most people at the time signaled their identities, their place in the hierarchical social system, in visible signs that everyone could read, like the indelible stains on a dyer’s hands. Poggio was barely legible. An isolated individual, considered outside the structures of family and occupation, made very little sense. What mattered was what you belonged to or even whom you belonged to. The little couplet Alexander Pope mockingly wrote in the eighteenth century, to put on one of the queen’s little pugs, could have applied in earnest in the world that Poggio inhabited:

I am his Highness’ dog at Kew;

Pray tell me, sir, whose dog are you?

The household, the kinship network, the guild, the corporation—these were the building blocks of personhood. Independence and self-reliance had no cultural purchase; indeed, they could scarcely be conceived, let alone prized. Identity came with a precise, well-understood place in a chain of command and obedience.

To attempt to break the chain was folly. An impertinent gesture—a refusal to bow or kneel or uncover one’s head to the appropriate person—could lead to one’s nose being slit or one’s neck broken. And what, after all, was the point? It was not as if there were any coherent alternatives, certainly not one articulated by the Church or the court or the town oligarchs. The best course was humbly to accept the identity to which destiny assigned you: the ploughman needed only to know how to plough, the weaver to weave, the monk to pray. It was possible, of course, to be better or worse at any of these things; the society in which Poggio found himself acknowledged and, to a considerable degree, rewarded unusual skill. But to prize a person for some ineffable individuality or for many-sidedness or for intense curiosity was virtually unheard of. Indeed, curiosity was said
²
by the Church to be a mortal sin. To indulge it was to risk an eternity in hell.

Who was Poggio, then? Why did he not proclaim his identity on his back, the way decent folks were accustomed to do? He wore no insignia and carried no bundles of merchandise. He had the self-assured air of someone accustomed to the society of the great, but he himself was evidently a figure of no great consequence. Everyone knew what such an important person looked like, for this was a society of retainers and armed guards and liveried servants. The stranger, simply attired, rode in the
company
of a single companion. When they paused at inns, the companion, who appeared to be an assistant or servant, did the ordering; when the master spoke, it became clear that he knew little or no German and that his native language was Italian.

If he had tried to explain to an inquisitive person what he was up to, the mystery of his identity would only have deepened. In a culture with very limited literacy, to be interested in books was already an oddity. And how could Poggio have accounted for the still odder nature of his particular interests? He was not in search of books of hours or missals or hymnals whose exquisite illuminations and splendid bindings made manifest their value even to the illiterate. These books, some of them jewel-encrusted and edged with gold, were often locked in special boxes or chained to lecterns and shelves, so that light-fingered readers could not make off with them. But they held no special appeal for Poggio. Nor was he drawn to the theological, medical, or legal tomes that were the prestigious tools of the professional elites. Such books had a power to impress and intimidate even those who could not read them. They had a social magic, of the kind associated for the most part with unpleasant events: a lawsuit, a painful swelling in the groin, an accusation of witchcraft or heresy. An ordinary person would have grasped that volumes of this kind had teeth and claws and hence have understood why a clever person might hunt them. But here again Poggio’s indifference was baffling.

The stranger was going to a monastery, but he was not a priest or a theologian or an inquisitor, and he was not looking for prayer books. He was after old manuscripts, many of them moldy, worm-eaten, and all but indecipherable even to the best-trained readers. If the sheets of parchment on which such books were written were still intact, they had a certain cash value, since they could be carefully scraped clean with knives, smoothed with talcum powder, and written over anew.
But
Poggio was not in the parchment-buying business, and he actually loathed those who scratched off the old letters. He wanted to see what was written on them, even if the writing was crabbed and difficult, and he was most interested in manuscripts that were four or five hundred years old, going back then to the tenth century or even earlier.
