Basilica of St. James

Prague, Czech Republic

The Basilica of St. James is a 17th-century church in Prague, Czech Republic, known for its dramatic Baroque facade. But just inside the door, a blackened, mummified human arm dangles from a chain, the alleged remains of a thief whose wrist was seized by a statue of Mary.

Prague's Baroque Stage

On the surface

The Basilica of St. James. A church on a narrow street just off Old Town Square.

Right beneath

Just inside the door, a blackened mummified human arm has hung from a chain for centuries — the alleged remains of a thief whose wrist was seized by a statue of Mary.

The hidden story

The patron of travelers

Saint James stands in the center of this swirling scene dressed as a humble traveler. He wears a wide-brimmed hat and carries a long walking staff tipped with a water gourd. During the Middle Ages, millions of people walked across Europe to visit his tomb in Spain. This relief captures the saint as the protector of all those weary pilgrims. The four figures around him are also travelers. They hold their own staves and look toward him for guidance on their dangerous journeys. Even the angels above join the movement by blowing trumpets to announce his presence.

Italian drama in Prague

A sculptor named Ottavio Mosto created this masterpiece in the late sixteen-hundreds. Mosto was famous for bringing Italian energy and emotion to the streets of Prague. Look at how the figures seem to spill out of the wall and into your space. He chose stucco instead of heavy stone to achieve these deep shadows and delicate folds. Stucco is a mix of lime, plaster, and sand. It is very soft and easy to mold before it hardens. This allowed Mosto to craft the tiny feathers on the angel wings and the bulging muscles in the pilgrims' legs.

The thief's heavy price

There is a gruesome physical relic hidden just inside the door to your right. A blackened, mummified human arm hangs from a high chain on the wall. Legend says a thief tried to steal the jewels from the altar inside. As he reached out, a statue of Mary grabbed his wrist and would not let go. The monks eventually had to cut the man's arm off to free him. You can still see the shriveled, leathery limb today. It dangles in the dim light as a warning to anyone with bad intentions. This strange, tactile piece of history makes the old stories of the church feel suddenly real.

Most visitors walk right past Basilica of St. James without ever knowing this.
