The Ghent Altarpiece has been known by various names since its creation. Artworks were rarely given specific titles until hundreds of years later. Most of the titles by which artworks are known today were given by art historians to facilitate reference. In Flemish, the altarpiece is known as Het Lam Gods, “The Lamb of God.” It has also been referred to by nicknames, such as The Mystic Lamb or simply and perhaps perceptibly, considering the frequency with which it has been imperiled, The Lamb.
Jan van Eyck painted The Mystic Lamb between 1426 and 1432, a tumultuous time in European history. King Henry V of England married Catherine of France, then died two years later. Joan of Arc was executed in the midst of the raging Hundred Years’ War. Brunelleschi began to build the dome of the cathedral of Florence, Santa Maria del Fiore. Donatello’s marvelous Saint George statue had recently been completed, a work that would influence sculpture much as The Ghent Altarpiece would influence painting. The very year that The Lamb was begun, Masaccio painted his celebrated Brancacci Chapel in Florence, which became a pilgrimage point for artists in subsequent centuries—what van Eyck did for panel painting, and Donatello did for sculpture, Masaccio did for wall painting. Soon after the completion of The Lamb, Leon Battista Alberti wrote his influential Treatise of the Art of Painting, mathematically and theoretically codifying the artistic rendition of perspective. A decade later, Gutenberg invented printing with movable type.
The fame of the altarpiece comes from its artistic beauty and interest—and also its importance to the history of art. This importance was constantly reasserted through the centuries, as one generation after another of artists, writers, and thinkers extolled the virtues of the painting, from Giorgio Vasari to Gotthold Ephraim Lessing to Erwin Panofsky to Albert Camus.
The painting both enchants the eye and provokes the mind. Elements of the work, such as the microscopically detailed crown that sits at God’s feet, are painted with raised, textural strips of real gold leaf, which catch the light like sparks on the painting’s surface. Beyond the dazzle, the painting is filled with disguised symbols linked to Catholic mysticism. It exhibits detail far greater than any of the works of van Eyck’s painter predecessors. The personalization of human figures, the stark naturalism of inanimate objects like that gilded, jewel-encrusted crown, forecast movements such as Realism by four hundred years.
In considering how to situate The Ghent Altarpiece in the history of art, one might pursue two different arguments, each of them convincing. One might argue that The Ghent Altarpiece was the last artwork of the Middle Ages, or one might state that this was the first painting of the Renaissance.
It was the last artwork of the Middle Ages because the form of the frame, the painted architecture, and the figures are Gothic in style. The extensive gilding, an effect added later by a gilder after the artist had completed his work, is also a Gothic characteristic. The gold makes the painted figures leap off the panels, lending them a halo of light and a striking delineation against the gilded sea behind them. Actual gold leaf, pounded so thin that it would disintegrate if touched by an oily fingertip, was applied by static electricity. A badger-fur brush was rubbed in the gilder’s own hair, creating static strong enough to pick up the gold leaf, which was affixed to the gesso by egg-white glue. Gilding would be dropped in favor of naturalistic landscaped background later in the fifteenth century, so its selective presence suggests an allegiance to the medieval style. The mastery of perspective, as well as the integration into the painting of Neoplatonic artistic theory, the preferred philosophy of the Humanists who sparked the Renaissance, are all absent. This was, therefore, the last major artwork of the Middle Ages.
And yet one might easily argue that the masterpiece represents the first painting of the Renaissance. Though there is gilding, the work also abounds with naturalistic landscapes and backgrounds, characteristic of postmedieval painting. The altarpiece was created during the height of Humanism: the rediscovery of classical Hebrew and Greek texts, and the particular idolization of the ancient Athenians. Its realism, unprecedented in the Middle Ages, was inspired by this Humanism. Part of the Renaissance Humanist philosophy was an empowerment of human capability and human lives. Only someone who embraced the value of humanity would bother to create an artwork full of such loving detail. During this era of the Christianization of pagan art and ideas, works of art reflected an attempt to reconcile the dominant Catholic religion with the contradictory philosophies and science expressed in newly discovered and translated classical texts. This Christianization of pagan imagery is integral to The Mystic Lamb. The fact that this painting was, in the decades after its creation, the most famous painting in the world among painters, and the fact that it effectively established the new artistic medium of the Renaissance, oil painting, demonstrate how it directly shaped Renaissance art and iconography.
Both cases are sound. There is a scholarly tendency to want to categorize at all costs, inserting artworks into particular “-isms” and overlooking the organic history of art, the way various styles overlap and intertwine. But part of the pleasure and wonder of great art is its mystery, its elusive qualities that haunt and intrigue us. Rather than relegating The Ghent Altarpiece to the Middle Ages or the Renaissance, the painting can be viewed more accurately as the fulcrum between the Middle Ages and the Renaissance, in art as well as thought—and it is all the more interesting because of its hybrid nature.
What is it a painting of? This seemingly simple question has a complex answer. Most religious paintings of the fifteenth century were inspired by, or precisely illustrated, a particular passage in the Bible, the Apocrypha, or biblical commentaries. The Ghent Altarpiece refers to many biblical and mystical texts, but is a synthesis rather than a precise illustration of any one of them. One must excavate the various layers of theological references and iconography before linking together the individual pieces into a constellation.
Pictures of this period were often puzzles. They led the viewer through a maze and only hinted at what lay at the center. It has often been said that a great portrait should reveal a hidden secret about the person portrayed that the person would prefer remained secret—the artist is privy to it and weaves the secret into the pigment, hiding it in plain sight for determined viewers to find, if they know how to look.
What is subtle and enigmatic in portraiture is magnified in religious painting. The subtlety of the theme on which knowledgeable viewers may meditate was also considered an advantage. Mystical secrets of Catholicism were not for novices, but rather for those with extensive knowledge of the Bible and commentaries and also Greek and Latin pagan sources. For example, van Eyck’s contemporary, the Italian monk Fra Angelico, painted a small fresco in each cell in the monastery of San Marco in Florence. The cells for novice monks contain simple biblical scenes, easy to understand, provoking more of a gut reaction, such as sympathy, with a Crucifixion or a Pietà. The scenes depicted are increasingly complex in the cells that Fra Angelico painted for the elder monks. The levels of theological complexity culminate in difficult concepts such as the Holy Trinity, images that would require wisdom, experience, and extensive reading in order to understand fully.
In religious paintings for public spaces, too, what one might describe as “mystery paintings” were favored. They would often include varying levels of complexity, depictions of biblical scenes that are easily recognizable for the simpler viewers, alongside erudite images, which often contained hybrids of various theological texts, references to mythology or pagan ideas, and time-and-place-specific references, what we might call “inside jokes” today, which were obvious to contemporary viewers but are like a foreign language to a twenty-first-century audience.
There was also a pleasure in deciphering. In a time before the printing press, one of the great pleasures of an educated life was to contemplate pictures over the span of hours, months, or years. Works such as The Mystic Lamb had a religious function, decorating and referencing the Mass that took place in the church at the altar beneath
it. But they were also sources of intellectual and aesthetic pleasure, something to be debated with friends. Viewers showed their erudition by noting references in painting, by identifying the various philosophical concepts raised by the painting, and by discussing how various ideas and images might be woven together into a sum that reveals a greater truth. Renaissance art conveyed ideas in images, painted stories, and pictograms, artists toying with ways of presenting concepts through the inherently silent, mostly textless medium of painting. Faces, landscapes, still lifes, and bodies had to tell stories. The great artists could use this mute medium to plumb emotional and theological mysteries.
The images in The Ghent Altarpiece are varied and theoretically diverse. The painting incorporates more than one hundred figures, many inscribed textual phrases, references and cross-references to biblical passages, apocryphal theologies, and even pagan mythology. Complicated symbolic works such as this one began with an overall iconographic plan that was designed by a scholar, a great theologian—rarely by the artist himself. The artist would be told the scheme of the painting, which figures should be included, which phrases, and perhaps even their relation to one another in the composition. It was up to the artist to execute the concept of the scholar. The more accomplished the artist, the less the art would be dictated to him.
In this case, Jan van Eyck was a relatively young up-and-comer. This would be his first major work for public display. Therefore he would have received a considerable amount of guidance. Under most circumstances, the implementation of individual concepts and the arrangement of figures were at the discretion of the artist, while the theme, any text, portraits of donors, and especially the number of figures would be expressed in the written contract. Painters were often paid by the number of faces they were asked to paint, so this was an important factor. The contract for The Ghent Altarpiece is lost, and we can only guess what it contained and how much of a free hand the artist was given in its conception. Likewise, no record remains of the scholar who designed the theme, although a probable candidate has been suggested. The scholar must have been inordinately well-read—a knowledgeable Humanist. One can imagine how difficult it must have been to summon up by memory or painstaking research the many phrases and cross-references employed in this work, without the benefit of a computer, a concordance, or even the access that the invention of printed type would provide twenty years later.
What may strike some viewers as a simple painting of a room is in fact a masterpiece of minute details, each with a specific liturgical or symbolic reference. Paintings of this period did not contain details without a reason. The enormous material expense of the purchase of smooth, flat panels, pricy pigments to make the paint, the wood-carved frames, and the cost and time of the artist’s work was so high that only the very wealthiest individuals and institutions—princes and kings and bishops and the wealthiest merchants—could commission art. Artists themselves could rarely afford the material to paint anything that had not been commissioned. It would be another two hundred years before the first artists began to paint “on spec,” in hopes of a sale through a gallery. Four hundred more years would pass before the first ready-mixed tubes of paint were available for purchase. In van Eyck’s day, artists created what they were paid for. Every detail was significant.
Art historians use iconography, the study of symbols in art, to determine the literary source that inspired paintings. Most religious works of the premodern period illustrate literary concepts or stories. Knowing the literary source reveals the theme of the painting, which might otherwise remain elusive. For religious works, the sources most often used are the Bible or The Golden Legend, the medieval biography of saints written circa 1260 by the monk Jacobus da Voragine, which was the second-most popular book (behind the Bible) through the Middle Ages and the Renaissance. A woman carrying her eyes on a silver platter might not have obvious meaning, until we know the literary source, The Golden Legend, and understand that the image comes from a biography of Saint Lucy, whose eyes were put out during her martyrdom.
A procession of the pantheon of saints, related to the All Saints sermon, moves slowly towards the Lamb on the altar at the center of a vast field. The theme of this central panel of The Ghent Altarpiece, called “The Adoration of the Mystic Lamb,” is drawn from The Golden Legend as well as the Revelation of Saint John. Therefore in the imagery of the altarpiece we find a series of interrelated theological themes, nested like Russian dolls, mutually referential while deepening the religious and iconographic mystery surrounding the painting. In the twenty-six individual scenes depicted across the twelve oak panels, we are presented with an A to Z of Christian mystical theology, from the Annunciation (Luke 1:26-28) to the Adoration of the Mystic Lamb in the final book of the New Testament, Revelation.
To unlock the mysteries of The Ghent Altarpiece, then, we must first approach its component parts, examining their content and symbolism and asking what the individual panels portray. Among its many mysteries are saints disguised as statues, floating prophets, and text written upside down.
When the altarpiece is closed, the verso (back) of eight of the panels is visible, illustrating the Mystery of the Incarnation. The panels are divided into two registers, each four panels across. The upper register depicts an open room in which the Annunciation takes place, the moment that God sends the angel Gabriel to tell Mary that she will bear the Son of God (Luke 1:28-38). This scene is painted across all four panels, with Old Testament prophets and sibyls floating above the painted “ceiling” of the Annunciation room.
The panel on the left shows the angel Gabriel with a lily in hand, a flower that symbolizes Mary’s virginity and purity and that Gabriel means no harm. Gabriel speaks the words of the Annunciation, which have been painted in gold onto the panel, emanating from Gabriel’s mouth: Ave Gratia Plena Dominus Tecum (“Hail [Mary], full of Grace, the Lord salutes you”). Gabriel’s body fills the room, in which he seems to float rather than stand. The room itself is contemporary to the painting, not biblically accurate, with exposed wooden crossbeams on the ceiling and a naturalistic light source: sunlight flooding through the open windows, which casts Gabriel’s shadow against the back wall.
Mary kneels on the right-hand side of the upper register, receiving the annunciated words of Gabriel. Her response to Gabriel’s words, Ecce ancilla domini (“Behold the slave of the Lord”), is written upside down. This may seem odd, until we realize that this reply is not for us, but rather for God and the Holy Spirit. The Holy Spirit, above Mary’s head, and God, presumably high above in Heaven and gazing down at Mary on earth, would need the response to be inverted in order for the text to be clearly legible. This contrivance appeared with some frequency in northern Renaissance Annunciation paintings, most famously and first here. The Latin phrase uttered by Mary is often mistranslated as “Behold the hand-maiden of the Lord,” a politically correct alteration of the literal translation, in which Mary offers herself as a slave.
The Angel Gabriel approaches Mary with a lily in hand
The Holy Spirit, in the form of a dove, descends upon her, signaling her impregnation with the future Christ. Her hands are crossed on her chest in a gesture of humility. She kneels on the floor as a further reference to her humility—humilitas in Latin, meaning “close to the earth.” A gorgeously rendered glass decanter, through which the window sunlight is cast, alludes to a medieval theological explanation for how Mary could become pregnant with Jesus yet still be a virgin. The rationale was that if a ray of light can pass through glass without breaking it, then Mary can be a pregnant virgin. This unusual validation worked to quiet the murmuring masses in the Middle Ages. Even back then, virgin pregnancy sounded a bit suspect.
The prophet Micah is in the crawl space above Mary. He indicates a passage in the Old Testament, inscribed in a waving painted banner, in which he predicted the coming of the Jewish messiah, a prophecy that medieval Christian theology appropriated as a prediction of the coming of Christ: “Out of thee shall he come fo
rth unto me that is to be ruler in Israel.” Van Eyck, like many artists, enjoyed paying homage to past artworks by quoting visual references to them. He chose to pose Micah identically to the 1417 sculptural relief of God carved by Donatello for the niche above his revolutionary statue of Saint George, which was on the façade of the church of Orsanmichele in Florence. This statue was considered the most important sculpture of its time, and Florence became a point of pilgrimage for fellow artists, who traveled across Europe to admire Donatello’s work. The admiring artists often referenced his work in theirs. Such visual, formal references by one artist to another appear frequently, and they form an inside joke for art historians, who take perhaps inordinately great pleasure in recognizing such references. But in many cases, as in this instance, they also serve up a clue that would otherwise have eluded scholars.
Mary kneels as the Holy Spirit descends upon her in the Annunciation
There is no clear evidence that Jan van Eyck ever traveled to Italy. But he would have needed to see the Donatello relief in order to reference it in his own painting. Because Gutenberg had not yet invented moveable type, copies of an artwork, image, or text had to be made by hand, one at a time. In order to see an artwork, one had to travel to its location. Visual references such as this are strong indicators that the artist saw the referenced work in person.
The prophet Zechariah is also depicted in what appears to be the crawl space above the painted ceiling, beneath the rounded top of the panel. A fragment of his messianic prophecy is inscribed in Latin, on a banner swirling over his head: “Rejoice greatly, O daughter of Zion, shout out behold, thy King cometh unto thee” (Zechariah 9:9).
