The Ghent Altarpiece- Art History and Significance Explained

What Is the Ghent Altarpiece?

The Ghent Altarpiece is a large polyptych painted by the Flemish brothers Jan van Eyck and Hubert van Eyck between 1432 and 1432. It sits in Saint Bavo's Cathedral in Ghent, Belgium, and it's one of the most important artworks from the early Northern Renaissance.

Its official name is "Adoration of the Mystic Lamb" (Lam Gods in Dutch). The altarpiece consists of 12 panels that fold together like doors. When closed, they show simple Annunciation scenes. When open, they reveal a dazzling display of saints, angels, and God himself.

You might hear people call it the Saint Bavo's Altarpiece or just the Ghent Altarpiece. Same thing. Don't let the naming confuse you.

The Van Eyck Brothers: Who Made This Thing?

Jan van Eyck was the primary artist behind the Ghent Altarpiece. His brother Hubert likely started the work before dying sometime before 1426. Jan finished it alone, and the piece was installed in Saint Bavo's Cathedral in 1432.

Jan van Eyck was one of the first artists to master oil painting as a medium. He used layer upon layer of oil paint to create depth and luminosity that tempera simply couldn't achieve. The Ghent Altarpiece showcases this technique at its finest.

Hubert van Eyck's exact contribution is debated. Some historians think he painted little of the actual work. Others argue he designed much of it. Jan signed the piece alone with the phrase "painted by Jan van Eyck." Whether this was ego or honesty, nobody knows for sure.

The Panels: What You'll Actually See

When Closed

The outside panels show the Annunciation. The Virgin Mary receives news from Gabriel that she'll bear God's son. It's painted in grisaille—basically gray to look like stone carvings. This was common for altarpiece exteriors.

When Open

The interior is where things get insane. The top register (when open) shows:

• Upper left: Adam and Eve, nude and anatomically detailed
• Upper center: God the Father surrounded by angels
• Upper right: The Virgin Mary as Queen of Heaven
• Upper far right: Angel playing music

The lower register shows the Adoration of the Mystic Lamb. Thousands of figures—including saints, martyrs, and Christian soldiers—gather around a lamb bleeding into a chalice on an altar. The lamb represents Christ. The gathering represents the heavenly Jerusalem.

There's a fountain in the background with water flowing toward the lamb. Scholars argue endlessly about what this means. Probably baptism or salvation. Nobody agrees.

The Art Historical Significance

The Ghent Altarpiece matters for several reasons:

• It pushed oil painting forward. Van Eyck's layering technique created textures and light effects that changed how artists worked. Other painters spent the next century copying his methods.
• It showed extreme realism for its time. The faces are individual, not generic. The landscape behind the lamb is detailed and believable. This wasn't common in 1432.
• It's enormous. The altarpiece measures about 11 by 15 feet when open. For its time, this was massive.
• It combines religious narrative with artistic virtuosity. The piece wasn't just devotional—it was meant to show off the wealth and taste of its patrons.

Art historians often cite the Ghent Altarpiece as the beginning of oil painting as a serious art form. That might be an exaggeration, but it's not far off.

The Just Judges Panel: The One That's Missing

Here's where it gets complicated. The altarpiece originally had 12 panels. Today, it has 11. The Just Judges panel was stolen in 1934 and has never been recovered.

Arsène Goedertier, a wealthy Belgian, hired thieves to steal the panel during a heist. The thieves left a note demanding a ransom. The Catholic Church paid. But they received only part of the panel. The rest vanished.

Goedertier died in 1934. On his deathbed, he reportedly told his lawyer that the panel was in a glass of water. Nobody found it. The lawyer died in 1960, taking the secret to his grave.

A copy of the Just Judges panel now occupies the original's spot. It was painted by copyists working from old photographs and descriptions. It's close but not the same.

The Stolen Years: World War I and World War II

The altarpiece has been stolen more than once. During World War I in 1914, German soldiers looted the altarpiece and shipped it to Germany as war spoils. It was recovered in 1919 after the war ended.

During World War II, the Nazis stole it again. This time, Allied forces tracked it down in an Austrian salt mine. The altarpiece was hidden among stolen treasures from across Europe. It was returned to Belgium in 1945.

Church officials got tired of this. After WWII, they moved the original panels to the Royal Museum of Fine Arts of Belgium for safekeeping. The cathedral kept the copies. This arrangement lasted until 1986.

Today, the altarpiece stays in Saint Bavo's Cathedral under climate-controlled conditions. The panels were restored multiple times, and a major restoration in 2019-2020 cleaned centuries of varnish and grime.

UNESCO Status

The Ghent Altarpiece became a UNESCO World Heritage Site in 2009. It's listed under "Flemish Béguinages," which also includes several other sites in Belgium. The altarpiece is the main attraction of this designation.

How to See the Ghent Altarpiece Today

Saint Bavo's Cathedral is open to visitors. You can see the altarpiece in person, though parts of it may be under restoration at any given time.

If you can't make it to Belgium, high-resolution digital scans exist online. The Closer to Van Eyck project digitized the entire altarpiece in extraordinary detail. You can zoom in on individual brushstrokes from your couch.

Ghent Altarpiece vs. Other Van Eyck Works

Why This Altarpiece Still Matters

The Ghent Altarpiece survived wars, theft, and centuries of neglect. It's still standing in the same cathedral where it was installed in 1432. That's remarkable.

It matters because it shows what oil painting could do when pushed to its limits. It matters because it tells a religious story that millions of people still connect with. It matters because it's one of the few early Renaissance pieces that stayed where it was meant to be.

You can argue about symbolism, attribution, and restoration. But standing in front of it, the thing is simply breathtaking. The light seems to come from within the paint itself. After 600 years, that's still something.
