Étiquette : Leonardo
Uccello, Donatello, Verrocchio and the art of military command. An inquiry into the key events and artistic achievements that created the Renaissance. By Karel Vereycken, Paris.
If there is still a lot to say, write and learn about the great geniuses of the European Renaissance, it is also time to take an interest in those whom the historian Georgio Vasari condescendingly called « transitional figures ».
How can one measure the contributions of Pieter Bruegel the Elder without knowing Pieter Coecke van Aelst? How can we value Rembrandt’s work without knowing Pieter Lastman? How did Raphaelo Sanzio innovate in relation to his master Perugino?
In 2019, an exceptional exhibition on Andrea Del Verrocchio (1435-1488), at the National Gallery in Washington, D.C., highlighted his great achievements, truly inspiring outbursts of great beauty that his pupil Leonardo da Vinci (1452-1519) would theorize and put to his greatest advantage.
The sfumato of Leonardo ? Verrochio is the pioneer, especially in the blurred features of portraits of women made with mixed techniques (pencil, chalk and gouache).
The joy of discovery
Leafing through the catalog of this exhibition, my joy got immense when I discovered (and to my knowledgne nobody else seems to have made this observation before me) that the enigmatic angel the viewer’s eye meets in Leonardo’s painting titled The Virgin on the Rocks (1483-1486) (Louvre, Paris), besides the movement of the body, is grosso modo a visual “quote” of the image of a terra cotta high relief (Louvre, Paris) attributed to Verrochio and “one of his assistants”, possibly even Leonardo himself, since the latter was training with the master as early as age seventeen ! The finesse of its execution and drapery also reminds us of the only known statue of Da Vinci, The Virgin with the laughing Child.
Many others made their beginnings in Verrocchio’s workshop, notably Lorenzo de Credi, Sandro Botticelli, Piero Perugino (Raphael’s teacher) and Domenico Ghirlandaio (Michelangelo’s teacher).
Coming out of the tradition of the great building sites launched in Florence by the great patron of the Renaissance, Cosimo de Medici for the realization of the doors of the Baptistery and the completion of the dome of Florence by Philippo Brunelleschi (1377-1446), Verrocchio conceived his studio as a true “polytechnic” school.
In Florence, for the artists, the orders flowed in. In order to be able to respond to all requests, Verrocchio, initially trained as a goldsmith, trained his students as craftsman-engineer-artists: drawing, calculation, interior decoration, sculpture, geology, anatomy, metal and woodworking, perspective, architecture, poetry, music and painting. A level of freedom and a demand for creativity that has unfortunately long since disappeared.
The Ghiberti legacy
In painting, Verrocchio is said to have begun with the painter Fra Filippo Lippi (1406-1469). As for the bronze casting trade, he would have been, like Donatello, Masolino, Michelozzo, Uccello and Pollaiuolo, one of the apprentices recruited by Lorenzo Ghiberti (1378-1455) whose workshop, starting from 1401, over forty years, will be in charge of casting the bronze bas-reliefs of two of the huge doors of the Baptistery of Florence.
Others suggest that Verrocchio was most likely trained by Michelozzo, the former companion of Ghiberti who said up shop with Donatello. As a teenager, Donatello had accompanied Brunelleschi on their joint expeditions to Rome to investigate the legacy of Greek and Roman art, and not only the architectural legacy.
In reality, Verrocchio only perpetuated and developed the model of Ghiberti’s « polytechnic » studio, where he learned the art. An excellent craftsman, Ghiberti was also goldsmith, art collector, musician and humanist scolar and historian.
His genius is to have understood the importance of multidisciplinarity for artists. According to him « sculpture and painting are sciences of several disciplines nourished by different teachings ».
The ten disciplines that he considered important to train artists are grammar, philosophy, history, followed by perspective, geometry, drawing, astronomy, arithmetic, medicine and anatomy.
You can discover, says Ghiberti, only when you managed to isolate the object of your research from interfering factors, and you can discover by detaching oneself from a dogmatic system;
Anticipating the type of biomimicry that will characterize Leonardo thereafter, Ghiberti affirms that he sought:
Ghiberti, who was familiar with some of the leading members of the circle of humanists led by Salutati and Traversari, based his own reflexions on optics on the authority of ancient texts, especially Arabic. He wrote:
Deliberately ignored (but copied) by Vasari, Ghiberti’s Commentaries are a real manuel for artists, written by an artist. Most interestingly, it is by reading Ghiberti’s Commentaries that Leonardo da Vinci became familiar with important Arab contributions to science, in particular the outstanding work of Ibn al Haytam (Alhazen) whose treatise on optics had just been translated from Latin into Italian under the title De li Aspecti, and is quoted at length by Ghiberti in his Commentario Terzio. Author A. Mark Smith suggests that, through Ghiberti, Alhazen’s Book of Optics
Ghiberti’s comments are not extensive. However, for the pupils of his pupil Verrocchio, such as Leonardo, who didn’t command any foreign language, Ghiberti’s book did make available in italian a series of original quotes from the roman architect Vitruvius, arab scientists such as Alhazen), Avicenna, Averroes and those european scientists having studied arab optics, notably the Oxford fransciscans Roger Bacon, John Pecham and the Polish monk working in Padua, Witelo.
Finally, in 1412, Ghiberti, while busy coordinating all the works on the Gates of the Baptistry, was also the first Renaissance sculptor to cast a life-size statue in bronze, his Saint John the Baptist, to decorate Orsanmichele, the house of the Corporations in Florence.
Lost wax casting
However, in order to cast bronzes of such a size, the artists, considering the price of metal, would use the technique known as “lost wax casting”.
This technique consists of first making a model in refractory clay (A), covered with a thickness of wax corresponding to the thickness of the bronze thought necessary.
The model is then covered with a thick layer of wet plaster (B) which, as it solidifies, forms an outer mold. Finally, the very hot molten bronze, pored into the mold it penetrates by rods (J) provided for this purpose, will replace the wax.
Finally, once the metal has solidified, the coating is broken. The details of the bronze (K) are then adjusted and polished (L) according to the artist’s choice.
This technique would become crucial for the manufacture of bells and cannons. While it was commonly used in Ifé in Africa in the 12th century for statuary, in Europe it was only during the Renaissance, with the orders received by Ghiberti and Donatello, that it was entirely reinvented.
In 1466, after the death of Donatello, it was Verrocchio’s turn to become the Medici’s sculptor in title for whom he produced a whole series of works, notably, after Donatello, his own David in bronze (Bargello National Museum, Florence).
If with this promotion his social ascendancy is certain, Verrocchio found himself facing the greatest challenge that any artist of the Renaissance could have imagined: how to equal or even surpass Donatello, an artist whose genius has never been praised enough?
This being said, let us now approach the subject of the art of military command by comparing four equestrian monuments:
- Roman Emperor Marcus Aurelius on the Capitoline square in Rome (175 AD) ;
- Paolo Uccello’s fresco of John Hawkwood in the church of Santa Maria del Fiore in Florence (1436);
- Erasmo da Narni, known as “Gattamelata” (1446-1450), casted by Donatello in Padua.
- Bartolomeo Colleoni by Andrea del Verrocchio in Venice (1480-1488).
Equestrian statues appeared in Greece in the middle of the 6th century B.C. to honor the victorious riders in a race. From the Hellenistic period onward, they were reserved for the highest state figures, sovereigns, victorious generals and magistrates. In Rome, on the forum, they constituted a supreme honor, subject to the approval of the Senate. Apart from being bronze equestrian statues, each one is placed in a place where their troops fought.
While each statue is a reminder of the importance of military and political command, the way in which this responsibility is exercised is quite different.
Marcus Aurelius in Rome
Marcus Aurelius was born in Rome in 121 A.D., into a noble family of Spanish origin. He was the nephew of the emperor Hadrian. After the death of Marcus Aurelius’ father, Hadrian entrusted him to his successor Antonin. The latter adopts and gives him an excellent education. He was initiated early in philosophy by his master Diognetus.
Interested in the stoics, he adopted for a while their lifestyle, sleeping on the ground, wearing a rough tunic, before he was dissuaded by his mother.
He went to Athens in 175 A.D. and became a promotor of philosophy. He helps financially the philosophers and the rhetoricians by granting them a fixed salary. Concerned with pluralism, he supported the Platonic Academy, the Lyceum of Aristotle, the Garden of Epicurus and the Stoic Portico.
On the other hand, during his reign, persecutions against Christians were numerous. He saw them as troublemakers – since they refused to recognize the Roman gods, and as fanatics.
Erected in 175 A.D., the statue was entirely gilded. Its location in antiquity is unknown, but in the Middle Ages it stood in front of the Basilica of St. John Lateran, founded by Constantine, and the Lateran Palace, then the papal residence.
In 1538, Pope Paul III had the monument of Marcus Aurelius transferred to the Capitol, the seat of the city’s government. Michelangelo restored the statue and redesigned the square around it, one of the fanciest in Rome. It is undoubtedly the most famous equestrian statue, and above all the only one dating back to ancient Rome that has survived, the others having been melted down into coins or weapons…
If the statue survived, it is thanks to a misunderstanding: it was thought that it represented Constantine, the first Roman emperor to have converted to Christianity at the beginning of the 4th century, and it was out of the question to destroy the image of a Christian ruler.
Neither the date nor the circumstances of the commission are known.
But the presence of a defeated enemy under the right foreleg of the horse (attested by medieval testimonies and since lost), the emperor’s gesture and the shape of the saddle cloth, unusual in the Roman world, make us to belief that the statue commemorated Marcus Aurelius’ victories, perhaps on the occasion of his triumph in Rome in 176, or even after his death. Indeed, his reign (161-180) was marked by incessant wars to counter the incursions of Germanic or Eastern peoples on the borders of an Empire that was now threatened and on the defensive.
The horse, while not that large, but looking powerful, has been sculpted with great care and represented with realism. Its nostrils are strongly dilated, its lips pulled by the bit reveal its teeth and tongue.
One leg raised, he has just been stopped by his rider, who holds the reins with his left hand. Like him, the horse turns his head slightly to the right, a sign that the statue was made to be seen from that side. Part of his harness is preserved, but the reins have disappeared.
The size of the athletic rider nevertheless dominates that of a powerful horse that he rides without stirrups (accessories unknown to the Romans). He is dressed in a short tunic belted at the waist and a ceremonial cloak stapled on the right shoulder. It is a civil and not a military garment, adapted to a peaceful context. He is wearing leather shoes held together by intertwined straps.
The statue is striking for its size (424 cm high) and for the majesty it exudes. Without armor or weapons, eyes wide open and without emotion, the emperor raises his right arm. His authority derives above all from the function he embodies: he is the Emperor who protects his Empire and his people by punishing their enemies without mercy.
The fresco by Paolo Uccello
In 1436, at the request of Cosimo de’ Medici, the young Paolo Uccello was commissioned to paint a fresco depicting John Hawkwood (1323-1394), the son of an English tanner who had become a warlord during the Hundred Years’ War in France and whose name would be Italicized into Giovanno Acuto.
Serving the highest bidder, especially rival Italian cities, Hawkwood’s company of mercenaries was no slouch.
In Florence, although it may seem paradoxical, it was the humanist chancellor Coluccio Salutati (1331-1406) who put Hawkwood at the head of a regular army in the service of the Signoria.
This approach is not unlike that of Louis XI in France, who, in order to control the skinners and other cutthroats who were ravaging the nation, did not hesitate to discipline them by incorporating them into a standing army, the new royal army.
The humanists of the Renaissance, notably Leonardo Bruni (1370-1440) in his De Militia (1420), became aware of the curse of using mercenaries in conflicts and of the fact that only standing army, i.e. a permanent army formed of professionals and even better by citizens and maintained by a state or a city could guarantee a lasting peace.
Although Hawkwood faithfully protected the city for 18 years, his ugly “professionalism” as a mercenary was not unanimously accepted, to the point of inspiring the proverb “Inglese italianato è un diavolo Incarnato” (« An Italianized Englishman is a devil incarnate »).
Petrarch denounced him, Boccaccio tried in vain to mount a diplomatic offensive against him, St. Catherine of Sienna begged him to leave Italy, Chaucer met him and, no doubt, used him as a model for The Knight’s Tale (The Canterbury Tales).
All this will not prevent Cosimo, a member of the humanist conspiracy and a great patron of the arts, returning from exile, from wanting to honor him. But in the absence of the bronze equestrian statue (which had been promised to him…), Florence, will only offer him a fresco in the nave of Santa Maria del Fiore, that is to say under right under the cupola of the Duomo.
From the very beginning, Paolo Uccello’s fresco seems to have stirred quite a controversy. A preparatory drawing in the collections of Florence’s Uffizi Museum indicates the commander, more armed, taller, and, with his horse in a more military position. Uccello had originally depicted Hawkwood as « more threatening », with his baton raised and horse « at the ready ».
A recent ultraviolet study confirms the fact that the painter had originally depicted the condottiere armed from head to toe. In the final version, he wears a sleeveless jacket, the giornea, and a coat; only his legs and feet are protected by a piece of armor. The final version presents a less imposing rider, less warlike, more human and more individualized
In the dispute, it was not Uccello who was considered faulty, but his sponsors. Moreover, the painter was quickly given the task of redoing the fresco in a way deemed “more appropriate”.
Unfortunately, there is no record of the debates that must have raged among the officials of the church fabric (Opera Del Domo). What is certain is the fact that in the final version, visible today, the condottiere has been transformed from a warlord running a gang of mercenaries, into the image of philosopher-king whose only weapon is his commanding staff. At the bottom of the fresco, we can read in Latin: “Giovanno Acuto, British knight, who was in his time held as a very prudent general and very expert in military affairs.”
The position of the horse and the perspective of the sarcophagus have been changed from a simple profile to a di sotto in su view.
If this perspective is somewhat surrealistic and the pose of the horse, raising both legs on the same side, simply impossible, it remains a fact that Uccello’s fresco will set “the standards” of the ideal and impassive image of virtue and command that must embody the hero of the Renaissance: his goal is no longer to “win” a war (the objective of the mercenary), but to preserve the peace by preventing it (the objective of a philosopher-king or simply a wise head of state).
As such, one might say that Uccello’s fresco announces the “paradigm shift” marking the end of the age of perpetual feudal wars, to that of the Renaissance, that is to say to that of a necessary concord between sovereign nation-states whose security is indivisible, the security of one being the guarantee of the security of the other, a paradigm even more rigorously defined in 1648 at the Peace of Westphalia, when it made the agapic notion of the “advantage of the other” the basis of its success.
One historian suggests that the recommissioning of Uccello’s fresco was part of the « refurbishing » of the cathedral associated with its rededication as Santa Maria del Fiore by the humanist Pope Eugene IV in March 1436, determined to convince the Eastern and Western Churches to peacefully overcome their divisions and réunite as was attempted at the Council of Florence of 1437-1438 and for which the Duomo was central.
Interesting is the fact that Uccello’s fresco appeared at around the same time that Yolande d’Aragon and Jacques Coeur, who had his Italian connections, persuaded the French king Charles VII to put an end to the Hundred Years’ War by setting up a permanent, standing army.
In 1445, an ordinance was passed to discipline and rationalize the army in the form of cavalry units grouped into Compagnies d’Ordonnances, the first permanent army at the disposal, not of warlords or aristocrats, but of the King of France.
Donatello’s “Gattamelata” (1447-1453)
It was only some years later, in Padua, between 1447 and 1453, that Donatello would work on the statue of Erasmo da Narni (1370-1443), a Renaissance condottiere, i.e. the leader of a professional army in the service of the Republic of Venice, which at the time ruled the city of Padua. An important detail is that Erasmo was nicknamed “il Gattamelata”.
In French, « faire la chattemite » means to affect a false air of sweetness to deceive or seduce… Others explain that his nickname of “honeyed cat” comes from the fact that his mother was called Melania Gattelli or that he wore a crest (a helmet) in the shape of a honey-colored cat in battle…
The man was of humble origin, the son of a baker, born in Umbria around 1370. He learned to handle weapons from Ceccolo Broglio, lord of Assisi, and then, when he was in his thirties, from the captains of Braccio da Montone, who was known for recruiting the best fighters.
In 1427, Erasmo, who had the confidence of Cosimo de’ Medici, signed a seven-year contract with the humanist Pope Martin V, who wished to strengthen an army corps loyal to his cause with the aim of bringing to heel the lords of Emilia, Romagna and Umbria who were rebellious against papal authority.
He bought a huge suit of armor to reinforce his high stature. He was not an impetuous fighter, but a master of siege warfare, which forced him to take slow, thoughtful and progressive action. He spied on his prey for a long time before trapping it.
In 1432, he captured the fortress of Villafranca near Imola by cunning alone and without fighting. The following year he did the same to capture the fortified town of Castelfranco, thus sparing his soldiers and his treasure.
Those who were unable to grasp his tactics, accused him of being a coward for “running away” from the front-line, not realizing, that on a given moment, this was part of the tactics of his winning strategy.
He was a prudent captain, with a very well-mannered troop, and he was careful to maintain good relations with the magistrates of the towns that employed him. He obtained the rank of captain-general of the army of the Republic of Venice during the fourth war against the Duke of Milan in 1438 and died in Padua in 1443. Following his death, the Venetian Republic gave him full honors and Giacoma della Leonessa, his widow, commissioned a sculpture in honor of her late husband for 1650 ducats.
The statue, which represents the life-size condottiere, in antique-style armor and bareheaded, holding his commanding staff in his raised right hand, on his horse, was made by the lost-wax method. As early as 1447, Donatello made the models for the casting of the horse and the condottiere. The work progresses at full speed and the work is completed in 1453 and placed on its pedestal in the cemetery that adjoins the Basilica of Padua.
Brilliant for his cunning and guile, Gattamelata was a thoughtful and effective fighter in action, the type of leader recommended by Machiavelli in The Prince, and which appears in the sixteenth century by François Rabelais in his account of the “Picrocholine wars”.
Not the brute power of weapons, but the cunning and the intelligence will be the major qualities that Donatello will make appear powerfully in his work.
Contrary to Marcus Aurelius, it is not his social status that gives the commander his authority, but his intelligence and his creativity in the government of the city and the art of war. Donatello had an eye for detail. Looking at the horse, we see that it is a massive animal but far from static. It has a slow and determined gait, without any hesitation.
But that’s not all. A rigorous analysis shows that the proportions of the horse are of a “higher order” than those of the condottiere. Did Donatello make a mistake and make Erasmo too small and the horse too large? No, the sculptor made this choice to emphasize the value of Gattamelata who, thanks to his skills, is able to tame even wild and gigantic animals. In addition, the horse’s eyes show him as wild and untameable. Looking at him, one could say that it is impossible to ride him, but Gattamelata manages it with ease and without effort.
Because if you look at the reins in the hands of the protagonist, you will notice that he holds them in complete tranquility. This is another detail that highlights Erasmus’ powerful cunning and ingenuity.
Next, did you notice that one of the horse’s legs rests on a sphere? If this sphere (which could also be a cannonball, since Erasmus was a warrior) serves to give stability to Donatello’s composition as a whole, it also indicates how this animal of gigantic strength (symbolizing here warlike violence), once tamed and well used, allows the globe (the earthly kingdom) to be kept in balance.
Having told you about the horse, it is time to know more about the condottiere.
He has a proud and determined expression. The baton of command, which he holds in his hand, delicately touches the horse’s mane. The baton is not just a symbolic object; he may have received it in 1438 from the Republic of Venice.
Unlike Uccello’s fresco, Gattamelata is not dressed as a contemporary prince of commander, but as a figure beyond time embodying both the past, the present and the future. To capture this, Donatello, who takes care of every detail, has taken an ancient model and modernized it with incredible results. The details of the protagonist’s armor include purely classical motifs such as the head of Medusa, taken from Marcus Aurelius, in Greek mythology one of the three gorgons whose eyes had the power to petrify any mortal who crossed her gaze.
Although the helmet of Gattamelata would have allowed to identify him at eyesight, Donatello has discarded this option. With a helmet on his head, he would have been the symbol of a bloodthirsty warrior, rather than a cunning man. Even better, the absence of a helmet allows the artist to show us a fearless commander whose fixed gaze shows his determination. With the figure slightly bowed and legs extended, the sword in its scabbard placed at an angle, Donatello gives the illusion of an “imbalance” that reinforces in the viewer’s mind the idea that the horse is advancing with full strength.
Art historian John Pope-Hennessy is emphatic:
As a result, Gattamelata is not a remake of the “classical Greek or Roman sculpture” of a hero with a sculpted physique, but a kind of new man who succeeds through reason. The fact that the statue has such a high pedestal also has its reason. Placed at such a height, the Gattamelata does not “share” our own space. It is in another dimension, eternal and out of time.
Some thirty years later, between 1480 and 1488, Andrea del Verrocchio, after a contest, was selected to make a large bronze equestrian statue of another Italian condottiere named Bartolomeo Colleoni (1400-1475).
A ruthless mercenary, working for a patron one day and his rival the next day, he served from 1454 the Republic of Venice with the title of general-in-chief (capitano generale). He died in 1475 leaving a will in which he bequeathed part of his fortune to Venice in exchange for the commitment to erect a bronze statue to his honor in St. Mark’s Square.
The Venetian Senate agreed to erect an equestrian monument to his memory, while charging the costs to the widow of the deceased…
In addition, the Senate refused to erect it in St. Mark’s Square, which was, along with St. Mark’s Basilica, at the heart of the city’s life. The Senate therefore decided to interpret the conditions set by Colleoni in his last will and testament without contradicting them, choosing to erect his statue in 1479, not in St. Mark’s Square, but in an area further from the city center in front of the Scuola San Marco, on the campo dei Santi Giovanni e Paolo.
Although Verrocchio had started working on the project since 1482, it remained unfinished at his death in 1488. And it is, not as Verrocchio wished, his heir Lorenzo di Credi who will cast the statue, but the Venetian Alessandro Leopardi (who lost the contest to Verrocchio), who will not hesitate to sign it!
If the horse is in conformity with the typology of the magnificent horses composing the quadriga overseeing the Basilica of Saint Mark of Venice (Greek statuary of the IVth century BC brought back by the crusaders from Constantinople to Venice in 1204) and of the horse of Marcus Aurelius, its musculature is more nervously underlined and traced. Objectively, this statue is ideally more proportionate. There is also more fine detail, a result of new pre-sculpture techniques, making the work captivating and realistic to look at.
The sculpture overflows its pedestal. According to André Suarès quoted in The Majesty of Centaurs:
His baton of command is even metamorphosed into a bludgeon! But since it is not Verrocchio who finished this work, let us not blame the latter for the warlike fury that emanates from this statue.
Venice, a vicious slave-trading financial and maritime Empire fronting as a “Republic”, clearly took its revenge here on the beautiful conception developed during the Renaissance of a philosopher-king defending the nation-state.
On the aesthetic level, this mercenary smells like an animal. As a good observer, Leonardo warned us: when an artist represents a man entirely imprisoned by a single emotion (joy, rage, sadness, etc.), he ends up painting something that takes us away from the truly human soul. This is what we see in this equestrian statue.
If, on the contrary, the artist shows several emotions running through the figure represented, the human aspect will be emphasized. This is the case, as we have seen, with Donatello’s Gattamelata, uniting cunning, determination and prudence to overcome fear the face of threat.
Leonardo’s own, gigantic project to erect a gigantic bronze horse, on which he worked for years and developed new bronze casting techniques, unfortunately was never build, seen the hectic circumstances.
Finally, beyond all the interpretations, let us admire the admirable know-how of these artists. In terms of craft and skill, it generally took an entire life to become able to realize such great works, not even mentioning the patience and boundless passion required.
Up to us to bring it back to life !

Leonardo da Vinci’s « Viruvian Man ». Since we’re commemorating this year (2020) Leonardo Da Vinci, who died 500 years ago, many silly things are presented by fake scholars trying to make a real living.
Since I was introduced into the canon of proportions of the human body during my training as a professional painter and engraver, I want offer you some hints on how to look at what is called Da Vinci’s « Vitruvian man », a drawing currently on exhibit at the Da Vinci show at the Louvre in Paris.
Hence, as Leonardo underlines himself in his notebooks, adopting Cusanus wordings, it is only with the « eyes of the mind » that art becomes visible, because the « eyes of the flesh » are intrensically blind to it.
Canons of proportions
Europe, and Classical Greece, as everybody should know, emerged largely by absorbing several major discoveries accomplished much earlier by other civilizations. Much of it came from Asia, but African and especially Egypt, were key.
The very practice of mummification, a process which takes at least 60 days of work, made Egypt the key area of anatomical research.
As demonstrated by early Egyptian sculpture, the exact size of the entire adult human body is 7,5 times the size of the head. The size of a newborn is only four heads, that of a seven year old, six heads and that of a 17 years old adolescent, 7 heads.
If one subdivides the overall 7.5 proportion, for an adult, from the top of the head till the lowest part of the torso, one measures four heads, one till the nipples, one till the belly button and a fourth one till the lowest part of the pubis. Going up from the sole till the middle of the pelvis, one measures 3.5 heads: 2 heads till the knee and 1.5 till the middle of the pelvis. That brings the total till 7.5 heads for the entire length of the adult human body and it is proportional in the sense that people with smaller heads also have small bodies.
Polikleitos versus Lysippus
In the Vth Century BC, the Greek sculptor Polikleitos’ spear bearer (The “Doryphoros”) of Naples National Archeological Museum applied this most beautiful canon of proportions, known as the “Polikleitos canon”.
During the Renaissance, the nostalgics of the Roman Empire preferred another Greek canon, that of Greek sculptor Lysippus (4th Century BC), formalized by the Roman author, architect and civil engineer, Vitrivius (1st century BC).
Vitruvius only transcribed the prevalent taste of his epoch. Roman sculptors, in order to give an athletic and heroic look to the Emperors which they were portraying, adopting the canon of Lysippus, could reduce the head of their models to only an eight of the total length of the body. The trick was that by reducing the relative size of the head, the body looked more preeminent and powerful, something most emperors, who were often physical failures, appreciated and secured their popularity. Even extreme cases of 12 to 15 heads of body length appeared. In short, Public relations ruled at the detriment of science and truth.
Today’s comic strip drawers chose proportions according to purpose:
–For real life, 7.5 or “normal canon”
–For a movie star, 8 heads, with the “idealistic canon”;
–For a fashion magazine: 8.5 heads;
–For a comic book hero: 9 heads for the “heroic canon”
Text accompanying Leonardo DaVinci’s Vitruvian Man:
Vitruvius, the architect, says in his work on architecture that the measurements of the human body are distributed by Nature as follows that is that 4 fingers make 1 palm, and 4 palms make 1 foot, 6 palms make 1 cubit; 4 cubits make a man’s height. And 4 cubits make one pace and 24 palms make a man; and these measures he used in his buildings. If you open your legs so much as to decrease your height 1/14 and spread and raise your arms till your middle fingers touch the level of the top of your head you must know that the centre of the outspread limbs will be in the navel and the space between the legs will be an equilateral triangle.
The length of a man’s outspread arms is equal to his height.
From the roots of the hair to the bottom of the chin is the tenth of a man’s height; from the bottom of the chin to the top of his head is one eighth of his height; from the top of the breast to the top of his head will be one sixth of a man. From the top of the breast to the roots of the hair will be the seventh part of the whole man. From the nipples to the top of the head will be the fourth part of a man. The greatest width of the shoulders contains in itself the fourth part of the man. From the elbow to the tip of the hand will be the fifth part of a man; and from the elbow to the angle of the armpit will be the eighth part of the man. The whole hand will be the tenth part of the man; the beginning of the genitals marks the middle of the man. The foot is the seventh part of the man. From the sole of the foot to below the knee will be the fourth part of the man. From below the knee to the beginning of the genitals will be the fourth part of the man. The distance from the bottom of the chin to the nose and from the roots of the hair to the eyebrows is, in each case the same, and like the ear, a third of the face.
Of course, Da Vinci’s exploration of the Vitruvian man doesn’t mean he approves or disapproves the stated fakery in proportions.
Soul or muscle?
It should be known that in Italy, the pure Roman taste has become trendy again following the discovery in 1506 of the statue of the Laocoon on the site of Nero’s villa in Rome. From that moment, artist will feel obliged to increase the volume of the muscular masses in order to appear as working « in Antique style ».
Although Leonardo never openly criticized this trend, it is hard not to think of Michelangelo’s frescoes in the Sistine Chapel, when the artist, seeking to raise the spirit to unequalled philosophical heights, advised painters: « do not give all the muscles of the figures an exaggerated volume » and « if you act differently, it is more a sort of representation of a sack of nuts that you will have achieved than to that of a human figure » (Codex Madrid II, 128r).
No doubt inspired by his friend, the architect Giacomo Andrea, in « The Vitruvian Man », Leonardo is above all interested by other harmonies: if a person extends his arms in a direction parallel to the ground, one obtains the same length as one’s entire height. This equality is inscribed by Leonardo in a square (symbol of the earthly realm). But if one stretches his arms and legs in a star shape, they are inscribed in a circle whose center is the navel. The location of the navel divides the body according to the golden ratio (in this example 5 heads out of a total of 8 heads, 5+3 being part of the Fibonnacci series: 1+2 = 3; 3+2 = 5; 5+3 = 8; 8+5 = 13; 13+8 = 21, etc.).
Leonardo clearly understood what the golden section really means: not a “magical” number in itself, but the reflexion of the dynamic of least action, the very principle uniting man (the square) with the creator and the universe (the circle).
So if you take a look, beware of what you see and especially what you don’t !

En 1992, j’ai réalisé une copie à taille réelle de la Vierge aux rochers, un des chefs-d’œuvre de Léonard de Vinci appartenant à la collection du Louvre.
La commanditaire, une enseignante habitant l’Est de la France, y tenait à titre pédagogique. Or, la ville où elle exerçait sa profession, n’avait pas de musée. Pour combler ce manque, elle installa plusieurs copies de maîtres anciens à son domicile.
C’est là qu’elle permettait à de nombreux enfants de vivre un de ces moments magiques qui font de notre existence un délice. Car dialoguer, lors d’un rendez-vous, avec un tableau d’une beauté extrême de Léonard, fait de nous des humains.
Pour des raisons divers, ma copie à fini à l’Eglise Saint-Laurent de Paris, proche de la gare de l’Est, où on peut l’admirer et où il garde à ce jour une bonne place pour tout ceux qui désirent prier et méditer.
En 1992, en m’attelant à copier avec précision cette œuvre, j’ai constaté une chose étrange qui n’a cessé de me troubler. En plus, les plus grand spécialistes de Léonard dont j’ai consulté les écrits (Martin Kemp, Carlo Pedretti ou encore Daniel Arasse), semblent tous avoir passé à coté d’une énorme « erreur » anatomique présent dans ce tableau. Certes, il est vrai qu’ils n’ont jamais copié des œuvres de ce type. Et évidemment, une fois identifiée, cette erreur ne quitte plus votre champs de vision ni votre esprit.
Les faits sont incontestables. Il s’agit d’une erreur anatomique majeure touchant l’ange situé à droite du tableau. Avant de préciser cette erreur, quelques mots sur l’œuvre comme un tout où cet ange joue un rôle majeur.
Le sens de l’œuvre
Le sujet de la Vierge aux rochers n’illustre aucun évènement spécifique des Évangiles et reste donc ouvert à toute interprétation. Il pourrait s’agir d’un évènement popularisé par le théologien du XIVe siècle Pietro Cavalca, quand saint Jean et le Christ enfant se sont retrouvés lors de la fuite de la sainte famille en Égypte.
L’ange serait alors l’archange Uriel qui, selon l’interprétation de Cavalca, protégeait l’enfant-ermite saint Jean. Or, Uriel, en hébreu lumière de Dieu, est l’ange qui apporte à l’humanité la connaissance et la compréhension du Divin.
Seule figure à nous regarder de face, c’est par lui que nous « entrons » dans le tableau. C’est lui qui pointe son doigt sur un des enfants, plus précisément Saint-Jean Baptise agenouillé en prière devant l’enfant Jésus qui à son tour le bénit. La Vierge, au centre, a sa main droite posée sur l’épaule de Saint-Jean Baptiste qui lui semble sur le bord d’un relief. Elle le protège et le retient. Entretemps, elle garde sa main protectrice au-dessus de l’enfant Jésus qui lui, également au bord d’un précipice, est protégé à son tour par la main de l’ange qui nous regarde. L’ange nous met donc sur la « bonne piste » pour comprendre le sens que Léonard a voulu faire ressortir de l’œuvre qui s’éloigne un peu de celui de l’immaculé conception, souhaité par ses commanditaires.
Il pourrait également s’agir d’une interprétation philosophique personnelle de Léonard de Vinci. Dans l’iconographie médiévale et pré-renaissante, l’ange de l’annonciation se rend auprès de Marie pour lui signifier que son heure est venue. Or, ici, l’ange se retourne vers nous tout en indiquant qu’il découvre sur place un autre annonciateur : saint Jean Baptiste.
Ce dernier, saint patron de la ville de Florence, fut parfois associé à Platon. Les grands humanistes de l’époque, en effet, considérait que la philosophie de Platon, bien qu’avec des limites et des imperfections, préfigurait le message de l’Évangile. Pour eux, les « petites lumières » de l’Antiquité (païenne) annonçaient timidement la grande lumière de la Chrétienté. Or, saint Jean Baptiste, qui avait vécu comme Platon avant le Christ, avait lui aussi annoncé sa venue. Par analogie, l’image de saint Jean Baptiste, pourrait être une métaphore du platonisme christianisé qui fut la puissance fondatrice de toute la Renaissance européenne.
A un moment où le Vatican, avec saint Thomas d’Aquin, avait fait le choix calamiteux de privilégier Aristote dont la philosophie est diamétralement contraire avec l’Évangile, le tableau de Léonard n’a pu qu’apparaître comme une terrible provocation. Le Vatican semble d’ailleurs ne lui avoir jamais pardonné car contrairement à Raphaël ou Michel-Ange, des propagandistes égotiques dont le contenu philosophique était largement inférieur à celui exprimé par Léonard, le Vatican n’a jamais honoré De Vinci de la moindre commande, une des raisons pour son départ pour la France.
Lorsque l’on scrute avec attention, comme j’ai dû le faire pour réaliser ma copie conforme, la position anatomique de l’ange en bas à droite, l’on constate la chose suivante :
–Contrairement à l’impression initiale, l’ange n’est pas assis sur son fessier ;
–L’ange est agenouillé sur son genou gauche qu’on identifie sous le vêtement rouge ;
–Son genou droit est donc en hauteur derrière le corps de l’ange ;
–Par contre, son pied droit est posé au sol sur la végétation. Il est visible et on peut compter les orteils ;
–Par conséquent, avec son corps, et donc sa colonne vertébrale, dans cette position, le positionnement de la tête de l’ange, telle qu’elle est peinte, est strictement impossible. Pour un être « normal », cette tête doit s’inscrire dans la prolongation de la courbe que forme la colonne vertébrale, c’est-à-dire fortement s’incliner vers la gauche.
Comment l’expliquer ?
J’appelle cette erreur « fantastique » non pas parce qu’elle est digne d’un élève, une autre hypothèse plausible, mais parce qu’elle nous apprend quelque chose sur nous mêmes.
Deux pistent offrent des hypothèses pourquoi tant de gens « n’ont rien vu » :
1) D’abord personne n’en a parlé et des milliers de copies ont déjà été réalisées. Notez que la plus connue, réalisée à l’époque et actuellement dans la collection du National Gallery de Londres, bien qu’elle a changé le sens de l’œuvre en amputant la main de l’ange, tente discrètement d’estomper l’erreur dont nous parlons ;
2) L’amour rend aveugle. Nous sommes « bon public » et donc nous nous imposons une forme de cécité. Tout d’abord, puisqu’il s’agit de Léonard de Vinci, un des plus grands génies de tous les temps, surtout en anatomie ! Ensuite, la « gestalt » du tableau comme un tout est d’une telle puissance et d’une telle beauté, que nous « pardonnons » immédiatement toute erreur de ce type. Un peu comme lorsqu’un bon pianiste nous joue une sonate magnifique de Beethoven. Tant que l’interprète nous traduit avec fidélité l’intention sublime du compositeur, nous « n’entendons » pas telle ou telle fausse note. Et c’est pareil en peinture.
