Guide by Henry Wadsworth Longfellow

It refers to the Teufelsbrücke, a stone arch bridge in the Schöllenen Gorge of Switzerland that spans the Reuss River along the St. Gotthard Pass route. According to local legend, the Devil constructed the bridge in return for the soul of the first being to cross it. Longfellow visited Switzerland, and this bridge is featured in his dramatic poem Christus: A Mystery (1872).

It’s an excerpt from Christus: A Mystery, Longfellow's lengthy dramatic poem released in 1872. The complete work is split into three sections: The Divine Tragedy, The Golden Legend, and The New England Tragedies. This particular scene is found in The Golden Legend, which takes place in medieval Europe.

That brevity is the whole joke. The guide has just given a long, excited speech about how terrifying and supernatural the gorge looks, and Lucifer — who is literally hiding under the bridge — simply laughs. He doesn’t need to explain himself. His presence confirms the legend, and his amusement at the tourists’ dramatic descriptions is the punchline.

Here, "cataract" refers to a large, powerful waterfall — specifically, the Reuss River's torrent as it crashes down through the Schöllenen Gorge. This term is an older literary expression for a waterfall of such magnitude and force, setting it apart from a gentle cascade.

The eight-line stanza uses an ABABCDCD rhyme scheme: Bridge / ridge, chasm / spasm, deep / cracked (a near-rhyme), cataract / steep (another near-rhyme). Longfellow maintains a brisk pace with the rhymes, matching the guide's lively, theatrical energy.

Christus: A Mystery is crafted as a dramatic poem — it resembles a play, complete with character names and stage directions, but it's designed for reading instead of performance. This approach allows Longfellow to introduce Lucifer into the scene without shifting into narration, preserving the intensity and theatricality of the moment.

Both at once, which is what makes it work. The guide's speech creates a truly eerie atmosphere — the gorge sounds frightening. But Lucifer's laugh at the end adds a layer of dark comedy. Longfellow is exploring the contrast between the tourist's theatrical delivery and the real supernatural presence just beneath the surface.

On the surface, it's about nature — particularly the awe-inspiring power of a mountain gorge and waterfall. However, it also delves into themes of fear (the chasm, the tumultuous water), the eerie presence of evil in our world, and how humans craft stories to make sense of intimidating landscapes. The Devil's laugh adds a touch of dark comedy, highlighting the contrast between how things seem and how they truly are.
