No visitor to Florence can miss the gilded bronze reliefs decorating the Porta del Paradiso (Gates of Paradise), the main gate of the Baptistery of Florence right in front of the Cathedral of Santa Maria del Fiore surmounted by Filippo Brunelleschi’s splendid cupola.
In this article, Karel Vereycken sheds new light on the contribution of Arab science and Ghiberti’s crucial role in giving birth to the Renaissance.
The Baptistery, erected on what most Florentines thought to be the site of a Roman temple dedicated to the Roman God of Mars, is one of the oldest buildings in the city, constructed between 1059 and 1128 in the Florentine Romanesque style. The Italian poet Dante Alighieri and many other notable Renaissance figures, including members of the Medici family, were baptized in this baptistery.
During the Renaissance, in Florence, corporations and guilds competed for the leading role in design and construction of great projects with illustrious artistic creations.
While the Arte dei Lana (corporation of wool producers) financed the Works (Opera) of the Duomo and the construction of its cupola, the Arte dei Mercantoni di Calimala (the guild of merchants dealing in buying foreign cloth for finishing and export), took care of the Baptistery and financed the embellishment of its doors.
The Gates of Paradise
The Baptistry, an octagonal building, has four entrances (East, West, North and South) of which only three (South, North and East) have sets of artistically important bronze doors with relief sculptures. Three dates are key : 1329, 1401 and 1424.
- In 1329, the Calimala Guild, on Giotto‘s recommendation, ordered Andrea Pisano (1290-1348) to decorate a first set of doors (initialy installed as the East doors, i.e. seen when one leaves the Cathedral, but today South). These consist of 28 quatrefoil (clover-shaped) panels, with the 20 top panels depicting scenes from the life of St. John the Baptist (the patron of the edifice). The 8 lower panels depict the eight virtues of hope, faith, charity, humility, fortitude, temperance, justice, and prudence, praised by Plato in his Republic and represented during the XVIth century by the Flemish humanist painter and reader of Petrarch, Peter Brueghel the Elder. Construction took 8 years, from 1330 till 1338.
- In 1401, after having narrowly won the competition with Brunelleschi, the 23 year old and inexperienced young goldsmith Lorenzo Ghiberti (1378-1455), is commissioned by the Calima Guild to decorate the doors which are today the North Gate. Ghiberti cast the bronze high reliefs using a method known as lost-wax casting, a technique that he had to reinvent entirely since it was lost since the fall of the Roman Empire. One of the reasons Ghiberti won the contest, was that his technique was so advanced that it required 20 % less (7 kg per panel) bronze than that of his competitors, bronze being a dense material far more costly than marble. His technique, applied to the entire decoration of the North Gate, as compared to his competitors, would save some estimated 100 kg of bronze. And since in 1401, with the plague regularly hitting Florence, economic conditions were poor, even the wealthy Calimala took into account the total costs of the program.
The bronze doors are comprised of 28 panels, with 20 panels depicting the life of Christ from the New Testament. The 8 lower panels show the four Evangelists and the Church Fathers Saint Ambrose, Saint Jerome, Saint Gregory, and Saint Augustine. The construction took 24 years.
- In 1424, Ghiberti, at age 46, was given—unusually, with no competition—the task of also creating the East Gate. Only in 1452 did Ghiberti, then seventy-four years old, install the last bronze panels, since construction lasted this time 27 years! According to Giorgio Vasari (1511-1574), Michelangelo Buonarroti (1475-1564) later judged them « so beautiful they would grace the entrance to Paradise ».
Over two generations, a bevy of well paid assistants and pupils were trained by Ghiberti, including exceptional artists, such as Luca della Robbia, Donatello, Michelozzo, Benozzo Gozzoli, Bernardo Cennini, Paolo Uccello, Andrea del Verrocchio and Ghiberti’s sons, Vittore and Tommaso. And over time, the seventeen-foot-tall, three-ton bronze doors became an icon of the Renaissance, one of the most famous works of art in the world.
In 1880, the French sculptor Auguste Rodin was inspired by it for his own Gates of Hell on which he worked for 38 year
Of utmost interest for our discussion here is the dramatic shift in conception and design of the bronze relief sculptures that occurred between the North and the East Gates, because it reflects how bot the artist as well as his patrons used the occasion to share with the broader public their newest ideas, inventions and exciting discoveries.
The themes of the North Gate of 1401 were inspired by scenes from the New Testament, except for the panel made by Ghiberti, « The Sacrifice of Isaac », which had won him the selection competition the same year. To complete the ensemble, it was therefore only logical that the East Gate of 1424 would take up the themes of the Old Testament.
Originally, it was the scholar and former chancellor of Florence Leonardo Bruni (1369-1444) who planned an iconography quite similar to the two previous doors. But, after heated discussions, his proposal was rejected for something radically new. Instead of realizing 28 panels, it was decided, for aesthetic reasons, to reduce the number of panels to only 10 much larger square reliefs, between borders containing statuettes in niches and medallions with busts.
Hence, since each of the 10 chapters of the Old Testament contains several events, the total number of scenes illustrated, within the 10 panels has risen to 37 and all appear in perspective :
- Adam and Eve (The Creation of Man)
- Cain and Abel (Jalousie is the origin of Sin)
- Noah (God’s punishment)
- Abraham and Isaac (God is just)
- Jacob and Esau
- David (Good commandor)
- Solomon and the Queen of Sheba
The general theme is that of salvation based on Latin and Greek patristic tradition. Very shocking for the time, Ghiberti places in the center of the first panel the creation of Eve, that of Adam appearing at the bottom left.
After the first three panels, focusing on the theme of sin, Ghiberti began to highlight more clearly the role of God the Savior and the foreshadowing of Christ’s coming. Subsequent panels are easier to understand. One example is the panel with Isaac, Jacob and Esau where the figures are merged with the surrounding landscape so that the eye is led toward the main scene represented in the top right.
Many of the sources for these scenes were written in ancient Greek, and since knowledge of Greek at that time was not so common, it appears that Ghiberti’s “theological advisor” was Ambrogio Traversari (1386-1439), with whom he had many exchanges.
Traversari was a close friend of Nicolas of Cusa (1401-1464), a protector of Piero della Francesca (1412-1492) and a key organizer of the Ecumenical Council of Florence of 1438-1439, which attempted to put an end to the schism separating the Church of the East from that of the West.
The bronze reliefs, known for their vivid illusion of deep space in relief, are one of the revolutionary events that epitomize the Renaissance. In the foreground are figures in high relief, which gradually become less protruding thereby exploiting the full illusionistic potential of the stiacciato technique later brought to its high point by Donatello. Using this form of “inbetweenness”, they integrate in one single image, what appears both as a painting, a low relief as well as a high relief. Or maybe one has to look at it another way: these are flat images traveling gradually from a surface into the full three dimensions of life, just as Ghiberti, in one of the first self-portraits of art history, reaches his head out of a bronze medal to look down on the viewers. The artist desired much more than perspective, he wanted breathing space!
This new approach will influence Leonardo Da Vinci (1452-1517). As art historian Daniel Arasse points out :
At the beginning of the 15th century, several theoretical approaches existed and eventuall contradicted each other. Around 1423-1427, the talentful sculptor Donatello, a young collaborator of Ghiberti, created his Herod’s Banquet, a bas-relief in the stiacciato technique for the baptismal font of the Siena Baptistery.
In this work, the sculptor deploys a harmonious perspective with a single central vanishing point. Around the same time, in Florence, the painter Massacchio (1401-1428) used a similar construction in his fresco The Trinity.
As we will see, Ghiberti, starting from the anatomy of the eye, opposed such an abstract approach in his works as well as in his writings and explored, as early as 1401, other geometrical models, called « binocular ». (see below).
Then, as far as our knowledge reaches, in 1407, Brunelleschi had conducted several experiments on this question, most likely based on the ideas presented by another friend of Cusa, the Italian astronomer Paolo dal Pozzo Toscanelli (1397-1482), in the latter’s now lost treaty Della Prospettiva. What we do know is that Brunelleschi sought above all to demonstrate that all perspective is an optical illusion.
Finally, it was in 1435, that the humanist architect Leon Baptista Alberti (1406-1472), in his treatise Della Pictura, attempted, on the basis of Donatello’s approach, to theorize single vanishing point perspective as a representation of a harmonious and unified three-dimensional space on a flat surface. Noteworthy but frustrating for us today is the fact that Alberti’s treatise doesn’t contain any illustrations.
However, Leonardo, who read and studied Ghiberti’s writings on, would use the latter’s arguments to indicate the limits and even demonstrate the dysfunctionality of Alberti’s “perfect” perspective construction especially when one goes beyond a 30 degres angle.
In the Codex Madrid, II, 15 v. da Vinci realizes that « as such, the perspective offered by a rectilinear wall is false unless it is corrected (…) ».
Perspectiva artificialis versus perspectiva naturalis
Alberti’s “perspectiva artificialis” is nothing but an abstraction, necessary and useful to represent a rational organization of space. Without this abstraction, it is fairly impossible to define with mathematical precision the relationships between the appearance of objects and the receding of their various proportions on a flat screen: width, height and depth.
From the moment that a given image on a flat screen was thought about as the intersection of a plane cutting a cone or pyramid, a method emerged for what was mistakenly considered as an “objective” representation of “real” three dimensional space, though it is nothing but an “anamorphosis”, i.e. a tromp-l’oeil or visual illusion.
What has to be underscored, is that this construction does away with the physical reality of human existence since it is based on an abstract construct pretending:
- that man is a single eyed cyclops;
- that vision emanates from one single point, the apex of the visual pyramid;
- that the eye is immobile;
- that the image is projected on a flat screen rather than on a curved retina.
Slanders and gossip
The crucial role of Ghiberti, an artist which “Ghiberti expert” Richard Krautheimer mistakenly presents as a follower of Alberti’s perspectiva artificialis, has been either ignored or downplayed.
Ghiberti’s unique manuscript, the three volumes of the Commentarii, which include his autobiography and which established him as the first modern historian of the fine arts, is not even fully translated into English or French and was only published in Italian in 1998.
Today, because of his attention to minute detail and figures « sculpted » with wavy and elegant lines, as well as the variety of plants and animals depicted, Ghiberti is generally presented as “Gothic-minded”, and therefore “not really” a Renaissance artist!
Giorgio Vasari, often acting as the paid PR man of the Medici clan, slanders Ghiberti by saying he wrote « a work in the vernacular in which he treated many different topics but arranged them in such a fashion that little can be gained from reading it. »
Admittedly, tension among humanists, was not uncommon. Self-educated craftsmen, such as Ghiberti and Brunelleschi on the one side, and heirs of wealthy wool merchants, such as Niccoli on the other side, came from entirely different worlds. For example, according to a story told by Guarino Veronese in 1413, Niccoli greeted Filippo Brunelleschi haughtily: « O philosopher without books, » to which Filippo replied with his legendary irony: « O books without philosopher ».
For sure, the Commentarii, are not written according to the rhetorical rules of those days. Written at the end of Ghiberti’s life, they may have simply been dictated to a poorly trained clerk who made dozens of spelling errors.
The Commentarii does reveal a highly educated author and a thinker having profound knowledge of many classical Greek and Arab thinkers. Ghiberti was not just some brilliant handcraft artisan but a typical “Renaissance man”.
In dialogue with Bruni, Traversari and the “manuscript hunter” Niccolo Niccoli, Ghiberti, who couldn’t read Greek but definitely knew Latin, was clearly familiar with the rediscovery of Greek and Arab science, a task undertaken by Boccaccio’s and Salutati’s “San Spirito Circle” whose guests (including Bruni, Traversari, Cusa, Niccoli, Cosimo di Medici, etc.) later would convene every week at the Santa Maria degli Angeli convent. Ghiberti exchanges moreover with Giovanni Aurispa, a collaborator of Traversari who brought back from Byzantium, years before Bessarion, the whole of Plato’s works to the West.
Amy R. Bloch, in her well researched study Lorenzo Ghiberti’s Gates of Paradise, Humanism, History, and Artistic Philosophy in the Italian Renaissance (2016), writes that « Traverari and Niccoli can be tied directly to the origins of the project for the Gates and were clearly interested in sculptural commissions being planned for the Baptistery. On June 21, 1424, after the Calima requested from Bruni his program for the doors, Traversari wrote to Niccoli acknowledging, in only general terms, Niccoli’s ideas for the stories to be included and mentioning, without evident disapproval, that the guild had instead turned to Bruni for advice. »
Ghiberti’s patron, sometimes advisor, and close associate was Palla Strozzi (1372-1462), who, besides being the the richest man in Florence with a gross taxable assets of 162,925 florins in 1427, including 54 farms, 30 houses, a banking firm with a capital of 45,000 florins, and communal bonds, was also a politician, a writer, a philosopher and a philologist whose library contained close to 370 volumes in 1462.
Just as Traversari and Bruni, Strozzi learned Latin and studied Greek under the direction of the Byzantine scholar Manuel Chrysoloras, invited to Florence by Salutati.
Ghiberti’s close relationship with Strozzi, writes Bloch, « gave him access to his manuscripts and, as importantly, to Strozzi’s knowledge of them. »
But there was more. « The relationship between Ghiberti and Palla Strozzi was so close that, when Palla went to Venice in 1424 as one of two Florentine ambassadors charged with negociating an alliance with the Venetians, Ghiberti accompanied him in his retinue. »
Strozzi was known as a real humanist, always looking to preserve peace while strongly opposing oligarchical rule, both in Florence as in Venice.
In fact it was Palla Strozzi, not Cosimo de’ Medici, who first set in motion plans for the first public library in Florence, and he intended for the sacristy of Santa Trinita to serve as its entryway. While Palla’s library was never realized due to the dramatic political conflict knows as the Albizzi Coup that led to his exile in 1434, Cosimo who got a free hand to rule over Florence, would make the library project his own.
A bold statement
Ghiberti begins the Commentarii with a bold and daring statement for a Christian man in a Christian world, about how the art of antiquity came to be lost:
Ghiberti understood the importance of multidisciplinarity for artists. According to him, “sculpture and painting are sciences of several disciplines nourished by different teachings”.
In book I of his Commentarii, Ghiberti gives a list of the 10 liberal arts that the sculptor and the painter should master : philosophy, history, grammar, arithmic, astronomy, geometry, perspective, theory of drawing, anatomy and medecine and underlines that the necessity for an artist to assist at anatomical dissections.
As Amy Bloch underscores, while working on the Gates, in the intense process of visualizing the stories of God’s formation of the world and its living inhabitants, Ghiberti’s engagement « stimulated in him an interest in exploring all types of creativity — not only that of God, but also that of nature and of humans — and led him to present in the opening panel of the Gates of Paradise (The creation of Adam and Eve) a grand vision of the emergence of divine, natural, and artistic creation. »
The inclusion of details evoking God’s craftmanship, says Bloch, « recalls similes that liken God, as the maker of the world, to an architect, or, in his role as creator of Adam, to a sculptor or painter. Teh comparison, which ultimately derives from the architect-demiurge who creates the world in Plato’s Timaeus, appears commonly in medieval Jewish and Christian exegesis. »
Philo of Alexandria wrote that man was modeled « as by a potter » and Ambrose metaphorically called God a « craftsman (artifex) and a painter (pictor) ». Consequently, if man is « the image of God » as says Augustine and the model of the « homo faber – man producer of things », then, according to Salutati, « human affairs have a similarity to divine ones ».
The power of vision and the composition of the Eye
Concerning vision, Ghiberti writes:
Now, any serious scholar, having worked through Leonardo’s Notebooks, who then reads Ghiberti’s I Commentarii, immediately realizes that most of Da Vinci’s writings were basically comments and contributions about things said or answers to issues raised by Ghiberti, especially respecting the nature of light and optics in general. Leonardo’s creative mindset was a direct outgrowth of Ghiberti’s challenging world outlook.
In Commentario 3, 6, which deals with optics, vision and perspective, Ghiberti, opposing those for whom vision can only be explained by a purely mathematical abstraction, writes that “In order that no doubt remains in the things that follow, it is necessary to consider the composition of the eye, because without this one cannot know anything about the way of seeing.” He then says, that those who write about perspective don’t take into account “the eye’s composition”, under the pretext that many authors would disagree.
Ghiberti regrets that despite the fact that many “natural philosophers” such as Thales, Democritus, Anaxagoras and Xenophanes have examined the subject along with others devoted to human health such as “Hippocrates, Galen and Avicenna”, there is still so much confusion.
Indeed, he says, “speaking about this matter is obscure and not understood, if one does not have recourse to the laws of nature, because more fully and more copiously they demonstrate this matter.”
Avicenna, Alhazen and Constantine
Therefore, says Ghiberti:
This is quite a statement! Here we have “the” leading, founding figure of the Italian and European Renaissance with its great contribution of perspective, saying that to get any idea about how vision functions, one has to study three Arab scientists: Ibn Sina, Ibn al Haytham and Qusta ibn Luqa ! Cultural Eurocentrism might be one reason why Ghiberti’s writings were kept in the dark.
Ibn al-Haytham (Alhazen) made important contributions to opthalmology and improved upon earlier conceptions of the processes involved in vision and visual perception in his Treatise on Optics (1021), which is known in Europe as the Opticae Thesaurus. Following his work on the camera oscura (darkroom) he was also the first to imagine that the retina (a curved surface), and not the pupil (a point) could be involved in the process of image formation.
Avicenna, in the Canon of Medicine (ca. 1025), describes sight and uses the word retina (from the Latin word rete meaning network) to designate the organ of vision.
Later, in his Colliget (medical encyclopedia), Ibn Rushd (Averroes, 1126-1198) was the first to attribute to the retina the properties of a photoreceptor.
Avicenna’s writings on anatomy and medical science were translated and circulating in Europe since the XIIIth century, Alhazen’s treatise on optics, which Ghiberti quotes extensively, had just been translated into Italian under the title De li Aspecti.
It is now recognized that Andrea del Verrocchio, whose best known pupil was Leonardo da Vinci (1452-1517) was himself one of Ghiberti’s pupils. Unlike Ghiberti, who mastered Latin, neither Verrocchio nor Leonardo mastered a foreign language.
What is known is that while studying Ghiberti’s Commentarii, Leonardo had access in Italian to a series of original quotations from the Roman architect Vitruvius and from Arab scientists such as Avicenna, Alhazen, Averroes and from those European scientists who studied Arab optics, notably the Oxford Fransciscans Roger Bacon (1214-1294), John Pecham (1230-1292) and the Polish monk working in Padua, Erazmus Ciolek Witelo (1230-1275), known by his Latin name Vitellion.
As stressed by Professor Dominque Raynaud, Vitellion introduces the principle of binocular vision for geometric considerations.
He gives a figure where we see the two eyes (a, b) receiving the images of points located at equal distance from the hd axis.
He explains that the images received by the eyes are different, since, taken from the same side, the angle grf (in red) is larger than the angle gtf (in blue). It is necessary that these two images are united at a certain point in one image (Diagram).
Where does this junction occur? Witelo says: « The two forms, which penetrate in two homologous points of the surface of the two eyes, arrive at the same point of the concavity of the common nerve, and are superimposed in this point to become one ».
The fusion of the images is thus a product of the internal mental and nervous activity.
The great astronomer Johannes Kepler (1571-1630) will use Alhazen’s and Witelo’s discoveries to develop his own contribution to optics and perspective. “Although up to now the [visual] image has been [understood as] a construct of reason,” Kepler observes in the fifth chapter of his Ad Vitellionem Paralipomena (1604), “henceforth the representations of objects should be considered as paintings that are actually projected on paper or some other screen.” Kepler was the first to observe that our retina captures an image in an inverted form before our brain turns it right side up.
Out of this Ghiberti, Uccello and also the Flemish painter Jan Van Eyck, in contact with the Italians, will construct as an alternative to one cyclopic single eye perspective revolutionary forms of “binocular” perspective while Leonardo and Louis XI’ court painter Jean Fouquet will attempt to develop curvilinear and spherical space representations.
In China, eventually influenced by Arab optical science breakthrough’s, forms of non-linear perspective, that integrate the mobility of the eye, will also make their appearance during the Song Dynasty.
Ghiberti will add another dimension to perspective: light. One major contribution of Alhazen was his affirmation, in his Book of Optics, that opaque objects struck with light become luminous bodies themselves and can radiate secondary light, a theory that Leonardo will exploit in his paintings, including in his portraits.
Already Ghiberti, in the way he treats the subject of Isaac, Jacob and Esau (Figure), gives us an astonishing demonstration of how one can exploit that physical principle theorized by Alhazen. The light reflected by the bronze panel, will strongly differ according to the angle of incidence of the arriving rays of light. Arriving either from the left of from the right side, in both cases, the Ghiberti’s bronze relief has been modeled in such a way that it magnificently strengthens the overall depth effect !
While the experts, especially the neo-Kantians such as Erwin Panofsky or Hans Belting, say that these artists were “primitives” because applying the “wrong” perspective model, they can’t grasp the fact that they were in reality exploring a far “higher domain” than the mere pure mathematical abstraction promoted by the Newton-Galileo cult that became the modern priesthood ruling over “science”.
Much more about all of this can and should be said. Today, the best way to pay off the European debt to “Arab” scientific contributions, is to reward not just the Arab world but all future generations with a better future by opening to them the “Gates of Paradise”.

By Karel Vereycken
Some friends asked me to elaborate on the following:
It is sometimes said that the introduction of Plato in the context of the Councils of Ferrara and Florence (1439) “triggered the explosion of the Italian Renaissance”.
And of the great humanist, the German Cardinal-philosopher Cusanus, it is said that he “brought to Florence Bessarion and Plethon, who were both Greek scholars of Plato and brought the entire works of Plato which had been lost in Europe for centuries”.
At the same time, goes the narrative, “the Medicis financed a crash program to translate the works of Plato. This excitement made the Italian Renaissance what it became”.
While Plato’s ideas and the renewal of greek studies did play a major role in triggering the European Renaissance, the preceding affirmations, as we shall document here, require some refinement.
Was the Italian Renaissance “triggered” by the Council of Florence?
Not really. It was rather –40 years earlier–, the “Greek language revival project” project of Coluccio Salutati (1332-1406), who would become the chancellor of Florence and invite the Greek scholar Manuel Chrysoloras (1355-1415) to his city, that “triggered” a revival of Greek and Hebrew studies, which in return lead to the unification of the churches at the Council of Florence (1439).
The idea had regained interest from Petrarch and Boccaccio, which Salutati admired. Along with Dante Alighieri (1265-1321), it is undoubtedly the Italian poet Petrarch (1304-1374) who best embodies the ideals guiding the humanists of the Renaissance.
All his life, it is said, Petrarch tried to
rediscover the very rich teaching of classical authors in all disciplines and, starting from this sum of knowledge, most often scattered and forgotten, to revive and pursue the research that these authors had begun.
After following his parents to Avignon, Petrarch studied in Carpentras where he learned grammar, then in Montpellier, rhetoric, and finally in Bologna, where he spent seven years at the school of jurisconsults.
However, instead of studying law, which in those days paved the way to a brilliant career, Petrarch secretly read all the classics hitherto known, including Cicero and Virgil, despite the fact that his father occasionally burned his books.
Petrarch and Barlaam of Samara
Under the pontificate of Benedict XII, Petrarch tried to learn Greek language with the help of a learned monk of the Order of St. Basil, Barlaam of Seminara (1290-1348), known as Barlaam the Calabrian, who came to Avignon in 1339 as ambassador of Andronic III Paleologus in an unsuccesful attempt to put an end to the schism between the Orthodox and Catholic Churches.
A philosopher, theologian and mathematician, Barlaam, while having limited knowledge of Greek and Latin, was one of the first to wish that the study of the Greek language and philosophy be reborn in Europe.
In his Treatise On my own ignorance and that of many others (1367), Petrarch declared himself proud of his Greek manuscripts – and of his library in general – and expressed his deep admiration for Barlaam :
I have at home sixteen works of Plato. I don’t know if my friends have ever heard the titles […]. And this is only a small part of Plato’s work, for I have seen, with my own eyes, a large number of them, especially in the Calabrian Barlaam, a modern model of Greek wisdom who began to teach me Greek while I was still ignorant of Latin, and who might have done so successfully if death had not taken him away from me and hindered my honest plans, as usual.
In 1350, two years after Barlaam’s death, Petrarch met the son of a banker, Giovanni Boccaccio (1313-1375). The latter, like Petrarch, fell in love with the greek culture and language. In his youth, in Naples, he too had met Barlaam and learned a few words of Greek, meticulously copying alphabets and verses, adding the Latin translation and pronunciation indications.
Boccaccio and Leontius Pilatus
To increase his mastery of Greek, Boccaccio then called from Thessaloniki a disciple of Barlaam, Leontius Pilatus (died in 1366), an austere, ugly and very bad-tempered character. But this Calabrian lectured him on Homer’s Iliad and Odyssey and translated sixteen of Plato’s dialogues. How could one get angry with him?
Boccaccio offered him shelter and food for three years in his home and had a chair of Greek created for him in Florence, the firs time ever!
Unfortunately, Pilatus did not really master this language. Although posing as a native Greek, the man had poor knowledge of ancient Greek and his translations never got beyond the level of word-for-word. As for the lessons he gave Petrarch, they were so brutal that he disgusted him forever.
This did not prevent Pilatus, at the insistence of Boccaccio, from translating Homer‘s Iliad and Odyssey into Latin from a Greek manuscript sent to Petrarch by Nicolaos Sigeros, the Byzantine ambassador to Avignon.
Hence, history being what it is, it was thanks to this highly imperfect translation that Europe rediscovered one of the great founding works of its culture!
And on this fragile ground will rise a flame that will revolutionize the world.
Was it not I, » writes Boccaccio in his Genealogy of the Gods, « who had the glory and honor of employing the first Greek verses among the Tuscans? Was it not I who, through my prayers, led Pilatus to settle in Florence and who housed him there? I brought at my own expense copies of Homer and other Greek authors when none existed in Tuscany. I was the first of the Italians to whom Homer, in particular, was explained, and then I had him explained in public.
The hunt for manuscripts
What is important is that during these encounters Petrarch created a cultural network covering the whole of Europe, a network reaching into the East.
He then asked his relations and friends, who shared his humanist ideal, to help him find in their country or province, the Latin texts of the ancients that the libraries of abbeys, individuals or cities might possess. In the course of his own travels he found several major texts that had fallen into oblivion.
It is in Liege (Belgium) that he discovered the Pro Archia and in Verona, Ad Atticum, Ad Quintum and Ad Brutum, all by Cicero. During a stay in Paris, he got his hands on the elegiac poems of Propertius, then, in 1350, on a work by Quintilian. In a constant concern to restore the most authentic text, he subjected these manuscripts to meticulous philological work and made corrections by comparing them with other manuscripts. This is how he reconstructed the first and fourth decades of the Roman History of Titus Livius from fragments and restored some of Virgil’s texts.
These manuscripts, which he kept in his own library, later came out in the form of copies and thus became accessible to the greatest number of people. While acknowledging that the pagans lacked the « true faith, » Petrarch believed that when one speaks of virtue, the old and new worlds are not at war.
The « Circolo di Santo Spirito »
From the 1360s onwards, Boccaccio gathered a first group of humanists known as the « Circolo di Santo Spirito » (Circle of the Holy Spirit), whose name was borrowed from the 13th century Florentine Augustinian convent.
An embryonic form of a university, its Studium Generale (1284) was then at the heart of a vast intellectual center including schools, hospices and refectories for the needy.
Before his death in 1375, Boccaccio, who had recovered part of Petrarch’s library, bequeathed to the convent his entire collection of precious ancient books and manuscripts.
Then, in the 1380s and early 1390s, a second circle of humanists met daily in the cell of the Augustinian monk Luigi Marsili (1342-1394). The latter, who had studied philosophy and theology at the universities of Paris and Padua, where he came already into contact with Petrarch in 1970, rapidly became friends with Boccaccio. Hence, by attending the Cercle Santo Spirito from 1375 onwards, Coluccio Salutati in turn fell in love with Greek studies.
By inviting the Greek scholar Manuel Chrysoloras (1355-1415) to Florence to teach Ancient Greek, it was Salutati who gave the decisive impulse leading to the end of the schism between East and West and thus to the unification of the Churches, consecrated at the Council of Florence in 1439.
A century before Salutati, the English philosopher and scientist Roger Bacon (1214-1294), a Franciscan monk residing in Oxford, author of one of the first Greek grammars, already called for such a « linguistic revolution ».
As wrote Dean P. Lockwood in Roger Bacon’s Vision of the Study of Greek (1919):
Obviously, Greek was the master-key to the great storehouse of ancient knowledge, Hebrew and Arabic to lesser chambers. Furthermore, we must no forget that in Bacon’s day the superiority of the ancients was an indisputable fact. The modern world has outstripped the Greek and the Romans in countless ways ; the medieval thinkers were still climbing toward the Hellenic standard.
Three things were clear to Roger Bacon : the need of Greek, the contemporary ignorance of Greek, and the feasability of acquiring Greek. The same may be said of Hebrew, but Bacon rightly put Greek first. Bacon’s program was simple :
1. Seek out the native Byzantine Greeks resident in Europe, preferably grammarians. The latter were very few, of course, but might be found in the Greek monasteries of Southern Italy.
2. From these and from any other available source let Greek books be sought. If this program were to be carried out, Bacon confidently prophetized taht results would not be long in forthcoming.
Manuel Chrysoloras, arrived in winter 1397, an event remembered by one of his most famous pupils, the humanist scholar Leonardo Bruni (1369-1444) and later chancellor of Florence at the time of the Council of Florence, as a great new opportunity: there were many teachers of law, but no one had studied Greek in northern Italy for 700 years.
Thanks to Chrysoloras, Bruni and Pier Paolo Vergerio the Elder were able to read Aristotle and especially Plato in the original greek version.
Until then, in Europe, Christians knew the names of Pythagoras, Socrates and Plato by their reading of the church fathers Origen, St. Jerome and St. Augustine.
The latter, in his City of God, did not hesitate to affirm that the « Platonists », that is Plato and those who assimilated his teaching (Plato et qui eum bene intellexerunt), were superior to all other pagan philosophers.
As we have demonstrated elsewhere, in particular in our study on Raphael and the School of Athens, it is to a large extent Plato’s optimistic and Promethean philosophical approach, for whom knowledge comes above all from the capacity for hypothesis and not from the mere testimony of the senses as Aristotle claims, that clearly provided the sap that allowed the Renaissance tree to offer humanity so many wonderful fruits.
Traversari’s humanist circle
The most famous pupil of Chrysoloras was Ambrogio Traversari (1386-1439), who became general of the Camaldolese order. Today honored as a saint by his order, Traversari was one of the first to conceptualize the type of “Christian Humanism” that would be promoted by Nicolaus of Cusa (Cusanus) and later Erasmus of Rotterdam (who framed the concept of “Saint-Socrates”) and the latter’s admirer Rabelais, uniting Plato with the Holy Scriptures, and the fathers of the Church.
According to Vespasiano de Bisticci, the court historian of the Court of Urbino, Traversari had weekly working sessions on Plato and Greek philosophy at the Santa Maria degli Angeli convent with the crème de la crème of European humanism:
According to Vespasiano de Bisticci, the court historian of Urbino, Traversari led weekly work sessions on Plato and Greek philosophy at the Florentine Convent of Santa Maria degli Angeli with the cream of European humanism in the fields of literature, theology, science, politics, town and country planning, education and the fine arts. Among those :
- The German cardinal-philosopher Nicolas of Cusa (Cusanus);
- Paolo dal Pozzo Toscanelli, the great physician and cartographer, also friend and protector of Piero della Francesca and Leonardo da Vinci.
- The erudite manuscript collector Niccolò Niccoli, adviser to Cosimo the Elder, heir to the Medici’s industrial and financial empire. Considered at the time to be the richest man in the West, Cosimo was one of the patrons of the sculptor Donatello ;
- Aeneas Sylvius Piccolomini, the future humanist pope Pius II;
- Leonardo Bruni, the apostolic secretary of Pope Innocent VII and his three successors. He succeeded Coluccio Salutati at the chancellery of Florence (1410-1411 and 1427-1444).
- The Italian statesman Carlo Marsuppini, passionate about Greek Antiquity, and successor of Bruni as Chancellor of the Republic of Florence after the latter’s death in 1444.
- The philosopher, antiquarian and writer Poggio Bracciolini. After having advised no less than nine popes (!), he was appointed Chancellor of the Republic of Florence following the death of Marsuppini in 1453;
- The politician and ambassador Gianozzi Manetti. In love with ancient Greek and Hebrew, his circle includes l’humaniste Francesco Filelfo, le traducteur Palla Strozzi and Lorenzo Valla ;
Chrysoloras in Florence
Chrysoloras remained only a few years in Florence, from 1397 to 1400, teaching Greek, starting with the rudiments. He moved on to teach in Bologna and later in Venice and Rome. Though he taught widely, a handful of his chosen students remained a close-knit group, among the first humanists of the Renaissance. As said before, among his pupils were numbered some of the foremost figures of the revival of Greek studies in Renaissance Italy.
Aside from Bruni and Ambrogio Traversari, they included Guarino da Verona and the Florentine banker Palla Strozzi (1372-1462), later the friend and protector of the sculptor and translator Lorenzo Ghiberti. It is worth noting that Strozzi paid part of Chrysoloras’ salary and had the books necessary for the new teaching brought from Constantinople and Greece.
Chrysoloras went to Rome on the invitation of Bruni, who was then secretary to Pope Gregory XII. In 1408, he was sent to Paris on an important mission from the emperor Manuel II Palaeologus (1350-1425). In 1413, he went to Germany on an embassy to the emperor Sigismund, the object of which was to decide on the site for the church council that assembled at Constance in 1415. Chrysoloras was on his way there, having been chosen to represent the Greek Church, when he died that year.
Chrysoloras translated the works of Homer and Plato’s Republic from Greek into Latin. His Erotemata (Questions-answers) which was the first basic Greek grammar in use in Western Europe, circulated initially as a manuscript before being published in 1484.
Widely reprinted, it enjoyed considerable success not only among his pupils in Florence, but also among later leading humanists, being immediately studied by Thomas Linacre at Oxford and by Erasmus when he resided at Cambridge. It’s text became the basic manual used by pupils of the Three Language College set up by Erasmus in Leuven in 1515.
Traversari meets Chrysoloras during his two stays in Florence in the summer of 1413 and in January-February 1414, and the old Byzantine scholar is impressed by the bilingual culture of the young monk; he sends him a long philosophical letter in Greek on the theme of friendship. Ambrogio himself expresses in his letters the highest consideration for Chrysoloras, and emotion for the benevolence he showed him.
It should also be noted that the rich humanist scholar Niccolò Niccoli, a great collector of books, opened his library to Traversari and put him in constant contact with the scholarly circles of Florence (notably Leonardo Bruni, and also Cosimo de Medici, of whom he was advisor), but also of Rome and Venice.
In 1423, Pope Martin V sent two letters, one to the prior of the Convent of Santa Maria degli Angeli, Father Matteo, and the other to Traversari himself, expressing his support for the great development of patristic studies in this establishment, and especially for the work of translation of the Greek Fathers carried out by Traversari.
The Pope had in mind the negotiations he was conducting at the time with the Greek Church: at the beginning of 1423, his legate Antonio de Massa returned from Constantinople and brought back with him several Greek manuscripts which were to be entrusted to Traversari for translation: notably the Adversus Græcos by Manuel Calécas, and for the classics the Lives and Doctrines of the Illustrious Philosophers by Diogenes Laërtius, a text which circulated for a long time only in Traversari’s Latin translation.
It was following these undertakings that Traversari expressed his great interest in seeing the schism between the Latin and Greek Churches resolved. At the end of 1423, Niccolò Niccoli provides Traversari with an old volume containing the entire corpus of the ancient ecclesiastical canons, and the learned monk expresses in his correspondence with the humanist his enthusiasm for being able to immerse himself in the life of the then united ancient Christian Church, and in the process he translates into Greek a long letter from Pope Gregory the Great to the prelates of the East.
Arrival of Plato’s mind
Were Bessarion and Plethon the first to bring the entire works of Plato to Europe?
Not really. While John Bessarion did indeed bring his own collection of the “complete works of Plato” in 1437 to Florence, they had already been brought to Italy earlier, most notably in 1423 by the Sicilian Giovanni Aurispa (1376-1459), who was the teacher of Lorenzo Valla (another collaborator with whom Cusanus exposed the fraud of the “Donation of Constantine” and a major source of inspiration of Erasmus).
In 1421 Aurispa was sent by Pope Martin V to act as the translator for the Marquis Gianfrancesco Gonzaga on a diplomatic mission to the Byzantine emperor, Manuel II Palaiologos.
After their arrival, he gained the favor of the emperor’s son and successor, John VIII Paleologus (1392-1448), who took him on as his own secretary. Two years later, he accompanied his Byzantine employer on a mission to the courts of Europe.
On 15 December 1423, 16 years prior to the Council of Florence of 1439, Aurispa arrived in Venice with the largest and finest collection of Greek texts to reach the west prior to those brought by Bessarion. In reply to a letter from Traversari, he says that he brought back 238 manuscripts.
These contained all of Plato’s works, most of them hitherto unknown in the West.
Plato’s works so far were only known very partially. In Sicily, Henry Aristippus of Calabria (1105-1162) had translated in Latin Plato’s Phaedo and Meno dialogues as early as 1160.
Platonists (such as Petrarch, Traversari, Cusanus or Erasmus), have nothing to do and even violently opposed “Neo-platonist” (such as Plotinus, Proclus, Iamblicus, Marsilio Ficino and Pico della Mirandola) whose influence would create what could and should be called a “counter-Renaissance”. Already Leibniz strongly warned against the “neo-Platonists” demanding Plato be studied in his original writings rather than through his commentators, however brilliant they might be: “non ex Plotino aut Marsilio Ficino, qui mira semper et mystica affectantes diceren tanti uiri doctrinam corrupere.” [Plato should be studied, but “Not from Plotinus nor Marsilio Ficino, who, by always striving to speak wonderfully and mystically, corrupt the doctrine of so great a man. »]
George Gemisthos « Plethon »
Now, let us enter Plethon, who thought Plato and Aristotle could each one play their own role. George Gemistos « Plethon » (1355-1452), was a follower of the radical “neo-Platonist” Michael Psellos (1018-1080). Around 1410 Gemistos created a “neo-Platonic” academy in Mistra (near the site of ancient Sparta) and added “Plethon” to his name to make it resemble to Plato. He was also an admirer of Pythagoras, Plato, and the “Chaldean Oracles”, which he ascribed to Zoroaster.
Gemistos came for the first time to Florence when he was fifteen years old and became an authority in Mistra. So at the time of the Council the Emperor, John VIII Paleologus, knew they were going to face some of the finest minds in the Roman Church on their own soil; he therefore wanted the best minds available in support of the Byzantine cause to accompany him. Consequently, the Emperor appointed George Gemistos as part of the delegation. Despite the fact that he was a secular philosopher — a rare creature at this time in the West — Gemistos was renowned both for his wisdom and his moral rectitude. Among the clerical lights in the delegation were John Bessarion, Metropolitan of Nicaea, and Mark Eugenikos, Metropolitan of Ephesus. Both had been students of Gemistos in their youth. Another non-clerical member of the delegation was George Scholarios: both a future adversary of Gemistos and a future Patriarch of Constantinople as Gennadios II. Initially, Gemistos was opposed to the unity of the western and eastern churches.
Not assisting at every theological debate during the Council of Florence in 439, he went in town to give lectures to intellectuals and nobles on the essence of Plato and Neo-platonic philosophy. Plethon also brought with him the text of the “Chaldean Oracles” attributed to Zoroaster.
While most of Plethon’s writing were burned, since he was suspected of heresy, a large number of Plethon’s autograph manuscripts ended up in the hands of his former student Cardinal Bessarion. On Bessarion’s death, he willed his personal library to the library of San Marco in Venice (where over 4000 Greeks resided). Among these books and manuscripts was Plethon’s Summary of the Doctrines of Zoroaster and Plato. This Summary was a summary of the Book of Laws, which Plethon wrote inspired by Plato’s laws. The Summary is a mixture of polytheistic beliefs with neo-Platonist elements.
While John Bessarion (1403-1472), a real humanist, took part in the Council in Ferrara (1437) and Florence (1439), and as the representative of the Greek, signed the decree of the Florentine Union, he held nevertheless to the principle: “I honor and respect Aristotle, I love Plato” (colo et veneror Aristotelem, amo Platonem). For him Platonic thought would have the right of citizenship equal to Aristotelian thought in the Latin world only when it appeared in an irenic interpretation to Aristotelianism and as not in contradiction with Christianity, since only such an interpretation of Platonism could succeed at that time.
Cosimo di Medici and Ficino
Did the Medicis finance a crash program to translate the works of Plato?
In 1397, Giovannni « di Bicci » de’ Medici (1360-1429) founded the Medici Bank. Giovanni owned two wool factories in Florence and was a member of two guilds: the Arte della Lana and the Arte del Cambio.
In 1402, he was one of the judges on the jury that selected Lorenzo Ghiberti’s design for the bronzes for the doors of the Baptistery of Florence.
In 1418, Giovanni di Bicci, wishing to endow his family with their own church, entrusted Filippo Brunelleschi, future architect of the famous dome of the Cathedral of Santa Maria del Fioro, the Duomo, with the task of radically transforming the basilica church of San Lorenzo and ordered Donatello to execute the sculptures.
Politically, the Medici family did not come to power until 1434, three years before the Council of Florence and at a time when the Renaissance was already in full swing.
Admittedly, Giovanni’s son and inheritor of his financial empire, Cosimo di Medici (1389-1464), known as the richest man of his epoch, became so inspired by Plethon that he acquired acomplete library of Greek manuscripts. He bought a copy of the Platonic Corpus (24 dialogues) from Plethon, and a copy of the Corpus Hermeticum of Hermes Trismegistus, acquired in Macedonia by an italian monk, Lionardo of Pistoia. Cosimo also decided to initiate a project to translate from the Greek into Latin, the totality of Plato’s works.
However, as said before, Leonardo Bruni (1369-1444), who after having been papal secretary became chancellor of the Florentine republic from 1427 till 1444, had already translated close to all of Plato’s works from Greek into Latin.
It should be underlined that the translator chosen by Cosimo was Marsilio Ficino (1433-99), the son of his personal physician and only five years old at the time of the Council of Florence in 1439. Cosimo had some severe doubts concerning Ficino’s capacities as translator. When the latter offers in 1456 his first translation, The Platonic Institutions, Cosimo asks him kindly not to publish this work and to learn first the Greek language… which Ficino learns then from Byzantine scholar John Argyropoulos (1415-1487), an Aristotelian pupil of Bessarion who rejected the Council of Florence’s epistomological revolution.
But seeing his age advancing and dispite his unfortunate descent into corruption, Cosimo finally gave him the post. He allocates him an annual stipend, the required manuscripts and a villa at Careggi, close to Florence, where Ficino would set up his “Platonic Academy” with a handful of followers, among which Angelo Poliziano (1454-94), Giovanni Pico della Mirandola (1463-1494) and Cristoforo Landino (1424-1498).
Ficino’s “Academy”, taking up the ancient neo-platonic tradition of Plotinus and Porphyry (as Ficino states himself) would organize each year a ceremonial banquet “neglected since one thousand two hundred years” on November 7, thought to be simultaneously the birthday of Plato and the day of his death.
After the dinner, the attendants would read Plato’s Symposium and then each of them would comment one of the speeches. The comments are demonstrations, without any real dialogue and void of the essence of real platonic thinking: irony. On top of that it is remarkable that most gatherings of Ficino’s academy were attended by the ambassador of Venice in Florence, notably the powerful oligarch Bernardo Bembo (1433-1519), father of “poet” cardinal Pietro Bembo, later special advisor to the evil Genovese “Warrior Pope” Julius II.
It was this alliance of the increasingly more degenerated Medici family, the Venetians Empire’s maritime slave trade and the neo-Platonists that gained dominant influence over the Curia of the Roman Catholic Church. The Medici’s clearly disliked Da Vinci (who never got an order from the Vatican and subsequently left Italy), and through their propaganda man Vasari made the world to belief that the Renaissance was their baby.
But before translating Plato, and at the specific demand of Cosimo, Ficino translated first (in 1462) the Orphic Hymns, the Sayings of Zoroaster, and the Corpus Hermeticum of Hermes Trismegistus the Egyptian (between 100 and 300 after BC).
It will be only in 1469 that Ficino will finish his translations of Plato after a nervousbreakdown in 1468, described by his contemporaries as a crisis of “profound melancholy”.
In 1470, and with a title plagiarized from Proclus, Ficino writes his “Platonic Theology or on the immortality of the Soul.” While completely taken in by esoteric neo-Platonism, he becomes a priest in 1473 and writes “The Christian Religion” without changing his neo-platonic pagan outlook, since he launches then an entire new series of translations of the neo-Platonists of Alexandria: he translates the fifty four books of Plotinus “Enneads”, Porphyry and Proclus.
Ficino, in his “Five Questions Concerning the Mind” explicitly attacks the Promethean conception of man:
Nothing indeed can be imagined more unreasonable than that man, who through reason is the most perfect of all animals, nay, of all things underheaven, most perfect, I say, with regard to that formal perfection that is bestowed upon us from the beginning, that man, also through reason, should be the least perfect of all with regard to that final perfection for the sake of which the first perfection is given. This seems to be that of the most unfortunate Prometheus. Instructed by the divine wisdom of Pallas, he gained possession of the heavenly fire, that is, reason. Because of this very possession, on the highest peak of the mountain, that is, at the very height of contemplation, he is rightly judged most miserable of all, for he is made wretched by the continual gnawing of the most ravenous of vultures, that is, by the torment of inquiry…” (…) “What do the philosophers say to these things? Certainly the Magi, followers of Zoroaster and Hostanes, assert something similar. They say that, because of a certain old disease of the human mind, everything that is very unhealthy and difficult befalls us…
The Florentine Neo-Platonic Academy, backed by the libido-driven Lorenzo de Medici (1449-1492) “The Magnificent”, will serve as a “Delphic” operation: defend Plato to better destroy him; praise him in such terms that he becomes discredited. And especially destroying Plato’s influence by opposing religion to science, at a point where Cusanus and his followers are succeeding to do exactly the opposite. Isn’t it bizarre that Cusa’s name doesn’t appear a single time in the works of Ficino or Pico della Mirandola, so overfed with all encompassing knowledge?
Lorenzo did protect artists such as Sandro Botticelli, whose Birth of Venus examplifies Lorenzo’s neo-platonic symbolism.
Infected with this evil neo-Platonism, Thomaso Inghirami (1470-1516), the chief librarian of pope Julius II, will accomplish nothing but this when dictating to the painter Raphaël the content of the Stanza in the Vatican some decades later.
Neo-platonic “melancholy”, which Albrecht Dürer went after in his famous engraving, will become the matrix for the romantics, the destructive virus affecting the symbolists and the so-called modern school. As for the revolution that Greek studies will bring about in the sciences, I refer you to our article on this website: 1512-2012: From Cosmography to Cosmonauts, Gerard Mercator and Gemma Frisius.
To conclude, here is a short list of translators, and I certainly forgot some of them, and their mastery of foreign languages. Even if some of them can’t be called « humanists », let’s thank them for everything they allowed us to discover. I’m profoundly convinved, that without them, man would certainly not have set foot on the Moon!
