A 14th-century poem shaped plague history for 700 years

For centuries, historians have traced the Black Death's path across Asia using a single source: a poetic story written in Aleppo in 1348. The problem is, it was never meant to be a historical record.

Researchers at the University of Exeter have now traced a widespread misconception about how the plague spread to this one misunderstood text — a literary form called a maqāma, essentially an Arabic poem meant to entertain, not document. In Ibn al-Wardi's version, the plague becomes a trickster character wandering from China through Central Asia to the Mediterranean over 15 years. Somewhere along the way, later historians stopped reading it as fiction and started treating it as fact.

How a Story Became Science

The confusion began in the fifteenth century when Arab chroniclers started quoting Ibn al-Wardi's narrative as if it were an eyewitness account. European historians followed suit. By the time modern geneticists entered the picture, the "Quick Transit Theory" — the idea that the bacterium traveled over 3,000 miles in just a few years — had become the dominant explanation for how the plague reached Europe so quickly.

But the genetic evidence doesn't quite fit the timeline. The bacteria almost certainly originated in Central Asia, yet the speed required to match Ibn al-Wardi's narrative seems unrealistic. "All roads to the factually incorrect description of the spread of the plague lead back to this one text," explains historian Nahyan Fancy. "It's like it is in the centre of a spider's web of myths about how the Black Death moved across the region."

The irony is sharp: a creative work designed to help people process unimaginable loss became the foundation for how we understand one of history's greatest catastrophes.

What the Poem Actually Tells Us

This doesn't make Ibn al-Wardi's maqāma worthless — it just means we've been reading it wrong. The text reveals something far more human than a travel itinerary: it shows how people living through the plague tried to make sense of it. The personification of plague as a wandering trickster, the dark humor woven through the narrative, the structure itself — these were coping mechanisms. Creative expression as a way to hold onto some control when everything else was collapsing.

Historians now recognize that at least three plague-themed maqāmas were written in 1348-49 alone, all intended to be performed or read aloud in a single sitting. They were communal experiences, shared stories that helped communities process collective trauma. In that context, they're phenomenal historical documents — just not about epidemiology.

Rewriting the Record

Freeing Ibn al-Wardi's poem from the burden of literal truth opens space for other questions. Historians can now look back at earlier, less famous epidemics — Damascus in 1258, Kaifeng in 1232-33 — and ask how communities remembered those crises, and how those memories shaped later understanding of the Black Death itself. The plague didn't travel in a straight line across a map. It moved through human memory, through stories, through the ways people chose to remember and retell their own survival.

What started as a correction to the historical record is becoming something deeper: a reminder that the stories we tell about catastrophe matter as much as the facts of catastrophe itself.
