Mapping the dead: an AI documentary scene of the Broad Street pump, 1854 (prompts)

This is the script and the exact prompt behind the Short about the Broad Street pump, London 1854. The scene is built from one true line, one prompt, one still image and one 10-second clip. Everything you see in the video is AI-generated: the images, the clips, the narration and Meo, the cat. The history is real.

The true line

> London, 1854. A doctor maps the dead, and the deaths cluster around one water pump.

A major cholera outbreak began in Soho on 31 August 1854. The physician John Snow plotted cases by address and found them clustered around the public pump on Broad Street (now Broadwick Street) at Cambridge Street. He took his evidence to the parish Board of Guardians on the evening of 7 September, and the pump handle was removed the next day. His printed map, with one black bar for each death, appeared in 1855.

Step 1: one true line

Start from a fact you can source. Here it is a place: one pump, and the deaths around it.

Step 2: the prompt

> 1854 London street map on a desk · black marks CROWDING ONE STREET · candle light · rain on the window · 9:16

Why it works: the capitalised words tell the model what the story is, and a map on a desk keeps the scene simple and the faces out of frame.

The full production prompt for the still:

> Vertical 9:16 photorealistic documentary still, 1080x1920. London 1854, night: a large hand-drawn street map spread on a wooden desk, many small black bar marks crowded around one street corner where a water pump symbol is drawn (no readable words), an inkwell and quill, candle light, rain on a dark window behind. Key subject in the zone 25%-62% from the top; bottom 25% calm low-detail ground. 35mm documentary film grain. No readable text, no letters, no numbers, no logos, no watermark; any people anonymous (from behind, silhouette or small, no clear faces).

Step 3: one still image

Generate one still and check it before you spend time on motion. Look for readable text that should not be there and marks that spread across the whole map instead of crowding one corner.

Step 4: ten seconds of motion

> A hand with a quill (only the hand) adds one more small black mark near the pump on the map, the candle flickers, rain runs down the window; static. No cuts, no faces, no text.

The Short also uses a street shot of the pump itself: Broad Street, Soho, London 1854 at dusk in light rain: an old cast-iron hand water pump on the pavement, a few anonymous Victorian people with buckets seen from behind, gas lamps, wet cobblestones, brick houses. Its clip: Rain falls, a figure from behind works the pump handle slowly, gas lamps flicker; slow push-in toward the pump.

Then: voice and sound

A calm narrator, rain, and the sound of a typewriter for the on-screen script.

Narration used in the Short

• London, 1854. A doctor maps the dead, and the deaths cluster around one water pump.
• Meo here, an AI. Four steps behind that shot.
• Step one, the true line. Removing that pump's handle became a famous moment in medicine.
• Step two, the prompt. A map on a desk, black marks crowding one street.
• Step three, one still. Candle light, ink, rain on the window.
• Step four, motion. A hand adds one more mark.
• The full script is in the description.

Sources

• Wikipedia: 1854 Broad Street cholera outbreak
• London Museum: John Snow, cholera and the Broad Street pump
• Linda Hall Library: John Snow

Death counts differ: 127 in the first three days and 420 by the end (Wikipedia), 500 in ten days (London Museum). Snow himself noted the outbreak may already have been declining before the handle was removed, so the "handle ended it" story is a simplification. I found no source for the weather that night, so the rain and the candle are a mood choice.
