The Brazen Serpent

Venice, Italy

"The Brazen Serpent" is an 18th-century painting by Giambattista Tiepolo, now located in Venice's Galleria dell'Accademia. Originally painted in the 1730s as a thirteen-meter frieze for a church on Giudecca island, the artwork showcases Tiepolo's innovative approach to painting light and perspective at a massive scale.

On the surface

A very long, narrow painting at the Accademia. People writhing around a bronze snake on a pole. Hard to make out from below.

Right beneath

The painting was designed for a spot so high above viewers that Tiepolo used steep perspective to make figures lean out of the frame — and his 'shorthand' technique of placing bright highlights next to deep shadows let him work faster than any rival.

The hidden story

A cure made of bronze

Moses lifts a metallic snake high above a crowd of suffering people. Giambattista Tiepolo painted this massive scene around 1732 for the church of Santi Cosma e Damiano in Venice. The story comes from the biblical Book of Numbers. God sent a plague of venomous snakes to punish the Israelites for complaining during their desert journey. Moses forged this bronze serpent and set it on a pole. Anyone bitten by a real snake survived if they looked at the bronze one.

Painted for the rafters

This canvas measures nearly thirteen meters long but stands only two meters high. Tiepolo designed this unusual shape to fit high on a church wall above the choir stalls. Because the painting sat so far above the viewer, he used a steep perspective. The figures seem to lean out over the edge of the frame. Earlier today at the Frari, you saw cityscapes built from thousands of tiny wood fragments. Tiepolo worked in the opposite way. He used massive, sweeping brushes to cover vast surfaces in record time.

The shorthand of a master

If you look closely at the clouds or the fabric, you see bold, jagged streaks of paint. Tiepolo was famous for his speed. He often finished large frescoes and canvases faster than other artists could even sketch them. He used a technique called shorthand. He did not blend every color perfectly on the canvas. Instead, he placed bright highlights right next to deep shadows. From a distance, your eye blends these marks together. This creates the shimmering light and sense of movement that define the Venetian Rococo style.

Healing through the gaze

The painting focuses on the act of looking as a form of physical and spiritual rescue. Every figure in the crowd reacts differently to the bronze icon. Some reach out in desperation while others collapse from the venom. For the monks who originally prayed beneath this frieze, the bronze serpent represented a prophecy of the cross. They believed that looking at the serpent saved the body, just as looking at Christ saved the soul. Tiepolo captured that tension through the chaotic tangle of limbs and snakes at the bottom of the frame.
