Chapter 1
Vinci, 1452-1464

Leonardo da Vinci had the good fitness to be innate out of wedlock. Otherwise, he would have been approaching to turn a notary, like the firstborn legitimate sons in his family stretching back at slightest 5 generations.

His family roots can be traced to the early 1300s, when his great-great- great-grandfather, Michele, used as a notary in the Tuscan mountain city of Vinci, about seventeen miles west of Florence.* With the arise of Italy’s trading economy, notaries played an critical role sketch up blurb contracts, land sales, wills, and other authorised papers in Latin, mostly garnishing them with chronological references and literary flourishes.

* Leonardo da Vinci is infrequently wrongly called “da Vinci,” as if that were his last name rather than a descriptor definition “from Vinci.” However, the use is not as gross as some purists proclaim. During Leonardo’s lifetime, Italians increasingly began to regularize and register the use of patrimonial surnames, and many of these, such as Genovese and DiCaprio, subsequent from family hometowns. Both Leonardo and his father, Piero, frequently appended “da Vinci” to their names. When Leonardo changed to Milan, his crony the justice producer Bernardo Bellincioni referred to him in essay as “Leonardo Vinci, the Florentine.”

Because Michele was a notary, he was entitled to the honorific “Ser” and so became famous as Ser Michele da Vinci. His son and grandson were even some-more successful notaries, the latter apropos a chancellor of Florence. The next in line, Antonio, was an anomaly. He used the honorific Ser and married the daughter of a notary, but he seems to have lacked the da Vinci ambition. He mostly spent his life vital off the deduction from family lands, tilled by sharecroppers, that constructed a medium volume of wine, olive oil, and wheat.

Antonio’s son Piero finished up for the enervation by ambitiously posterior success in Pistola and Pisa, and then by about 1451, when he was twenty-five, substantiating himself in Florence. A agreement he notarized that year gave his work residence as “at the Palazzo del Podestà,” the magistrates’ building (now the Bargello Museum) confronting the Palazzo della Signoria, the chair of government. He became a notary for many of the city’s monasteries and eremite orders, the town’s Jewish community, and on at slightest one arise the Medici family.

On one of his visits back to Vinci, Piero had a attribute with an unwed internal rancher girl, and in the open of 1452 they had a son. Exercising his little-used notarial handwriting, the boy’s grandfather Antonio available the birth on the bottom of the last page of a cover that had belonged to his own grandfather. “1452: There was innate to me a grandson, the son of Ser Piero my son, on the 15th day of April, a Saturday, at the third hour of the night [about 10 p.m.]. He bears the name Leonardo.”

Leonardo’s mom was not deliberate worth mentioning in Antonio’s birth footnote nor in any other birth or benediction record. From a taxation request 5 years later, we learn only her first name, Caterina. Her temperament was prolonged a poser to complicated scholars. She was suspicion to be in her mid-twenties, and some researchers speculated that she was an Arab slave, or maybe a Chinese slave.

In fact, she was an orphaned and bankrupt sixteen-year-old from the Vinci area named Caterina Lippi. Proving that there are still things to be rediscovered about Leonardo, the art historian Martin Kemp of Oxford and the archival researcher Giuseppe Pallanti of Florence constructed justification in 2017 documenting her background.

Born in 1436 to a bad farmer, Caterina was orphaned when she was fourteen. She and her tot hermit changed in with their grandmother, who died a year later, in 1451. Left to deflect for herself and her brother, Caterina had a attribute in Jul of that year with Piero da Vinci, then twenty-four, who was distinguished and prosperous.

There was little odds they would marry. Although described by one progressing biographer as “of good blood,” Caterina was of a opposite social class, and Piero was substantially already pledged to his future wife, an suitable match: a sixteen-year-old named Albiera who was the daughter of a distinguished Florentine shoemaker. He and Albiera were marry within eight months of Leonardo’s birth. The marriage, socially and professionally fitting to both sides, had likely been arranged, and the dowry contracted, before Leonardo was born.

Keeping things neat and convenient, shortly after Leonardo was innate Piero helped to set up a matrimony for Caterina to a internal rancher and kiln worker who had ties to the da Vinci family. Named Antonio di Piero del Vaccha, he was called Accattabriga, which means “Troublemaker,” yet opportunely he does not seem to have been one.

Leonardo’s consanguine grandparents and his father had a family residence with a tiny garden right next to the walls of the palace in the heart of the encampment of Vinci. That is where Leonardo may have been born, yet there are reasons to consider not. It competence not have been available or suitable to have a profound and then breast-feeding rancher lady vital in the swarming da Vinci family home, generally as Ser Piero was negotiating a dowry from the distinguished family whose daughter he was formulation to marry.

Instead, according to fable and the internal traveller industry, Leonardo’s hearth may have been a gray mill reside lodge next to a farmhouse two miles up the highway from Vinci in the adjacent community of Anchiano, which is now the site of a tiny Leonardo museum. Some of this skill had been owned given 1412 by the family of Piero di Malvolto, a close crony of the da Vincis. He was the godfather of Piero da Vinci and, in 1452, would be a godfather of Piero’s baby son, Leonardo—which would have finished clarity if Leonardo had been innate on his property. The families were very close. Leonardo’s grand father Antonio had served as a declare to a agreement involving some tools of Piero di Malvoto’s property. The records describing the sell contend that Antonio was at a circuitously residence personification backgammon when he was asked to come over for that task. Piero da Vinci would buy some of the skill in the 1480s.

At the time of Leonardo’s birth, Piero di Malvoto’s seventy-year-old widowed mom lived on the property. So here in the community of Anchiano, an easy two-mile walk from the encampment of Vinci, vital alone in a farmhouse that had a run-down lodge next door, was a widow who was a devoted crony to at slightest two generations of the da Vinci family. Her decayed lodge (for taxation functions the family claimed it as uninhabitable) may have been the ideal place to preserve Caterina while she was pregnant, as per internal lore.

Leonardo was innate on a Saturday, and the following day he was baptized by the internal clergyman at the bishopric church of Vinci. The baptismal rise is still there. Despite the resources of his birth, it was a immeasurable and open event. There were 10 godparents giving witness, including Piero di Malvoto, distant some-more than the normal at the church, and the guest enclosed distinguished internal gentry. A week later, Piero da Vinci left Caterina and their tot son behind and returned to Florence, where that Monday he was in his bureau notarizing papers for clients.

Leonardo left us no criticism on the resources of his birth, but there is one delicious reference in his notebooks to the favors that inlet bestows on a adore child. “The man who has retort aggressively and uneasily will furnish children who are irked and untrustworthy,” he wrote, “but if the retort is finished with good adore and enterprise on both sides, the child will be of good intellect, witty, lively, and lovable.” One assumes, or at slightest hopes, that he deliberate himself in the latter category.

He apart his childhood between two homes. Caterina and Accattabriga staid on a tiny plantation on the hinterland of Vinci, and they remained accessible with Piero da Vinci. Twenty years later, Accattabriga was operative in a kiln that was rented by Piero, and they served as witnesses for any other on a few contracts and deeds over the years. In the years following Leonardo’s birth, Caterina and Accattabriga had 4 girls and a boy. Piero and Albiera, however, remained childless. In fact, until Leonardo was twenty-four, his father had no other children. (Piero would make up for it during his third and fourth marriages, having at slightest eleven children.)

With his father vital generally in Florence and his mom nurturing a flourishing family of her own, Leonardo by age 5 was essentially vital in the da Vinci family home with his leisure-loving grandfather Antonio and his wife. In the 1457 taxation census, Antonio listed the dependents staying with him, including his grandson: “Leonardo, son of the pronounced Ser Piero, non legittimo, innate of him and of Caterina, who is now the lady of Achattabriga.”

Also vital in the domicile was Piero’s youngest brother, Francesco, who was only fifteen years older than his nephew Leonardo. Francesco hereditary a adore of country convenience and was described in a taxation request by his own father, in a pot-calling-the-kettle way, as “one who hangs around the villa and does nothing.” He became Leonardo’s beloved uncle and at times broker father. In the first book of his biography, Vasari creates the revelation mistake, after corrected, of identifying Piero as Leonardo’s uncle.


As Leonardo’s well-attended benediction attests, being innate out of nuptials was not a means for open shame. The nineteenth-century informative historian Jacob Burckhardt went so distant as to tag Renaissance Italy “a golden age for bastards.” Especially among the statute and superb classes, being deceptive was no hindrance. Pius II, who was the pope when Leonardo was born, wrote about visiting Ferrara, where his welcoming party enclosed 7 princes from the statute Este family, among them the reigning duke, all innate out of wedlock. “It is an unusual thing about that family,” Pius wrote, “that no legitimate successor has ever hereditary the principate; the sons of their mistresses have been so much some-more advantageous than those of their wives.” (Pius himself fathered at slightest two deceptive children.) Pope Alexander VI, also during Leonardo’s lifetime, had mixed mistresses and deceptive children, one of whom was Cesare Borgia, who became a cardinal, commander of the pope armies, an employer of Leonardo, and the theme of Machiavelli’s The Prince.

For members of the center classes, however, illegitimacy was not as straightforwardly accepted. Protective of their new status, merchants and professionals shaped guilds that enforced dignified strictures. Although some of the guilds supposed the deceptive sons of their members, that was not the case with the Arte dei Giuduci e Notai, the princely (founded in 1197) guild of judges and notaries to which Leonardo’s father belonged. “The notary was a approved declare and scribe,” Thomas Kuehn wrote in Illegitimacy in Renaissance Florence. “His honesty had to be above reproach. He had to be someone entirely in the mainstream of society.”

These strictures had an upside. Illegitimacy liberated some talented and free-spirited immature men to be artistic at a time when creativity was increasingly rewarded. Among the poets, artists, and artisans innate out of nuptials were Petrarch, Boccaccio, Lorenzo Ghiberti, Filippo Lippi, his son Filippino, Leon Battista Alberti, and of march Leonardo.

Being innate out of nuptials was some-more formidable than merely being an outsider. It combined an ambiguity of status. “The problem with bastards was that they were partial of the family, but not totally,” wrote Kuehn. That helped some be, or forced them to be, some-more brave and improvisational. Leonardo was a member of a middle-class family but apart from it. Like so many writers and artists, he grew up feeling a partial of the universe but also detached. This dilapidation extended to inheritance: a multiple of opposing laws and paradoxical justice precedents left it misleading either a son innate out of nuptials could be an heir, as Leonardo was to find out in authorised battles with his stepbrothers many years later. “Management of such ambiguities was one of the hallmarks of life in a Renaissance city-state,” explained Kuehn. “It was associated to the some-more distinguished creativity of a city like Florence in the humanities and humanism.”

Because Florence’s guild of notaries barred those who were non legittimo, Leonardo was means to advantage from the note-taking instincts that were inbred in his family birthright while being free to pursue his own artistic passions. This was fortunate. He would have finished a bad notary: he got wearied and dreaming too easily, generally when a plan became slight rather than creative.


Another upside for Leonardo of being innate out of nuptials was that he was not sent to one of the “Latin schools” that taught the classics and humanities to well-groomed determined professionals and merchants of the early Renaissance. Other than a little training in blurb math at what was famous as an “abacus school,” Leonardo was generally self-taught. He mostly seemed defensive about being an “unlettered man,” as he dubbed himself with some irony. But he also took honour that his miss of grave drill led him to be a footman of knowledge and experiment. “Leonardo da Vinci, disscepolo della sperientia,” he once sealed himself. This agnostic opinion saved him from being an coadjutor of normal thinking. In his notebooks he unleashed a blast at what he called the pretentious fools who would calumniate him for this:

I am entirely wakeful that my not being a man of letters may means certain haughty people to consider that they may with reason censure me, alleging that we am a man but learning. Foolish folk! … They strut about puffed up and pompous, embellished out and ornate not with their own labors, but by those of others…. They will contend that given we have no book training we can't scrupulously demonstrate what we enterprise to describe—but they do not know that my subjects need knowledge rather than the difference of others.

Thus was Leonardo spared from being lerned to accept dry Scholasticism or the Gothic dogmas that had amassed in the centuries given the decrease of exemplary scholarship and strange thinking. His miss of bend for management and his eagerness to plea viewed knowledge would lead him to qualification an experimental ensue for bargain inlet that foreshadowed the systematic process grown some-more than a century after by Bacon and Galileo. His process was secure in experiment, curiosity, and the ability to marvel at phenomena that the rest of us frequency postponement to contemplate after we’ve outgrown the consternation years.

To that was combined an heated enterprise and ability to observe the wonders of nature. He pushed himself to know shapes and shadows with opposite precision. He was quite good at divining movement, from the motions of a fluttering wing to the emotions flickering opposite a face. On this substructure he built experiments, some conducted in his mind, others with drawings, and a few with earthy objects. “First we shall do some experiments before we ensue further,” he announced, “because my goal is to deliberate knowledge first and then with logic show given such knowledge is firm to work in such a way.”

It was a good time for a child with such ambitions and talents to be born. In 1452 Johannes Gutenberg had just non-stop his edition house, and shortly others were using his moveable-type press to imitation books that would commission unschooled but shining people like Leonardo. Italy was commencement a singular forty-year duration during which it was not wracked by wars among its city-states. Literacy, numeracy, and income were rising dramatically as energy shifted from patrician landowners to civic merchants and bankers, who benefited from advances in law, accounting, credit, and insurance. The Ottoman Turks were about to capture Constantinople, unleashing on Italy a emigration of journey scholars with bundles of manuscripts containing the ancient knowledge of Euclid, Ptolemy, Plato, and Aristotle. Born within a year of Leonardo were Christopher Columbus and Amerigo Vespucci, who would lead an epoch of exploration. And Florence, with its sepulchral businessman difficulty of status-seeking patrons, had turn the cradle of Renaissance art and humanism.


The many clear memory Leonardo had of his decline was one he available fifty years later, when he was study the moody of birds. He was essay about a hawk-like bird called a kite, which has a split tail and superb prolonged wings that concede it to soar and glide. Observing it with his standard acuity, Leonardo viewed precisely how it non-stop its wings and then widespread and lowered its tail when it landed. This worried a memory from when he was a baby: “Writing about the kite seems to be my destiny given among the first recollections of my infancy, it seemed to me that, as we was in my cradle, a kite came to me and non-stop my mouth with its tail and struck me several times with its tail inside my lips.” Like much of what came from Leonardo’s mind, there was substantially some anticipation and fabulism in the brew. It is tough to suppose a bird actually alighting in a cradle and meddling open a baby’s mouth with its tail, and Leonardo appears to acknowledge this by using the word “it seemed to me,” as if it were maybe partly a dream.

All of this—a childhood with two mothers, an mostly absent father, and a dreamlike verbal confront with a fluttering tail—would yield good provender for a Freudian analyst. And it did—from Freud himself. In 1910 Freud used the kite story as the substructure for a brief book, Leonardo da Vinci and a Memory of His Childhood.

Freud got off to a stumbling start by using a bad German interpretation of Leonardo’s note that incorrectly called the bird a vulture rather than a kite. This sent him into a prolonged tangential reason about the symbolism of vultures in ancient Egypt and the etymological attribute of the difference for vulture and mother, all of which was irrelevant and, Freud after admitted, embarrassing. Leaving aside the bird mix-up, the categorical bearing of Freud’s research was that the word for tail in many languages, including Italian (coda), is jargon for “penis” and that Leonardo’s memory was associated to his homosexuality. “The conditions contained in the fantasy, that a vulture non-stop the mouth of the child and forcefully belabored it with its tail, corresponds to the thought of fellatio,” Freud wrote. Leonardo’s restricted desires, he speculated, were channeled into his hectic creativity, but he left many works unprepared given he was inhibited.

These interpretations have stirred some harmful critiques, many famously by art historian Meyer Schapiro, and they seem, at slightest to me, to exhibit some-more about Freud than about Leonardo. Biographers should be cautious about psychoanalyzing someone who lived 5 centuries earlier. Leonardo’s dreamlike memory may have simply reflected his lifelong seductiveness in the moody of birds, which is how he framed it. And it does not take a Freud to know that passionate drives can be sublimated into aspiration and other passions. Leonardo pronounced so himself. “Intellectual passion drives out sensuality,” he wrote in one of his notebooks.

A better source for discernment into Leonardo’s infirm impression and motivations is another personal memory he recorded, this one about hiking nearby Florence. The correlation concerned chancing on a dim cove and introspective either he should enter. “Having wandered some stretch among murky rocks, we came to the mouth of a good cavern, in front of which we stood some time, astonished,” he recalled. “Bending back and forth, we tried to see either we could learn anything inside, but the dim within prevented that. Suddenly there arose in me two discordant emotions, fear and desire—fear of the melancholy dim cave, enterprise to see either there were any miraculous thing within.”

Desire won. His unstoppable oddity triumphed, and Leonardo went into the cave. There he discovered, embedded in the wall, a hoary whale. “Oh strong and once-living instrument of nature,” he wrote, “your immeasurable strength was to no avail.” Some scholars have insincere that he was describing a anticipation travel or riffing on some verses by Seneca. But his cover page and those surrounding it are filled with descriptions of layers of hoary shells, and many fossilized whale skeleton have in fact been detected in Tuscany.

The whale hoary triggered a dim prophesy of what would be, via his life, one of his deepest forebodings, that of an baleful deluge. On the next side of the piece he described at length the mad energy once held by the long-dead whale: “You lashed with swift, branching fins and split tail, formulating in the sea remarkable tempests that buffeted and submerged ships.” Then he incited philosophical. “Oh time, quick criminal of all things, how many kings, how many nations hast thou undone, and how many changes of states and of resources have happened given this opposite fish perished.”

By this indicate Leonardo’s fears were about a area distant opposite from whatever dangers competence be sneaking inside the cave. Instead they were driven by an existential dismay in the face of the mortal powers of nature. He began scribbling rapidly, using a silverpoint on a red-tinted page, describing an canon that starts with water and ends with fire. “The rivers will be deprived of their waters, the earth will no longer put onward her greenery; the fields will no some-more be embellished with fluttering corn; all the animals, anticipating no fresh weed for pasture, will die,” he wrote. “In this way the cultivatable and cultivatable earth will be forced to finish with the component of fire; and then its surface will be left burnt up to dust and this will be the finish of all conceivable nature.”

The dim cove that Leonardo’s oddity compelled him to enter offering up both systematic discoveries and talented fantasies, strands that would be interwoven via his life. He would weather storms, literally and psychologically, and he would confront dim recesses of the earth and soul. But his oddity about inlet would always propel him to try more. Both his fascinations and his forebodings would be voiced in his art, commencement with his depiction of Saint Jerome painful nearby the mouth of a cove and culminating in his drawings and papers about an baleful deluge.
