Strasbourg, 1518: the dance that became a story of death

In the summer of 1518, people in Strasbourg began dancing in a way that alarmed the city. Its council recorded medical consultations, pilgrimages and a public ban. Centuries later an unnamed woman acquired the name “Frau Troffea”, and reports of many deaths appeared. This dossier follows the sources to separate the documented episode from the legend.

A city interrupted by moving bodies

Strasbourg, then a free city of the Holy Roman Empire, experienced an unusual disturbance in July 1518. People danced in a way that relatives, physicians and officials understood as an affliction rather than a celebration. There is no footage, individual clinical log or first-person account from every participant. There are, however, city orders, a letter to the bishop and accounts close to the event. They allow us to reconstruct the city’s responses without pretending to know each dancer’s movements.

The familiar name “dance of death” assumes an outcome that the closest records do not demonstrate. This episode is also distinct from the danse macabre, the medieval artistic motif in which Death leads people of different social ranks. The similar names have helped generate misleading imagery.

The first dancer was unnamed in the record

Accounts near the event speak of a woman who began dancing in mid-July and others who followed. 14 July comes from one chronicle tradition; a reconstruction of annals associated with Sebastian Brant gives 22 July. There is no secure opening-day register that settles the difference. Historian Élisabeth Clementz points out that the 1518 texts she examines (annals, a chronicle and the city’s reply to the bishop) never name the woman. They mention roughly fifty people affected.

“Frau Troffea”, a fixture of videos and articles, entered the story through a later route. Paracelsus wrote about a woman named Troffea but did not visit Strasbourg until 1526, years after the episode; the name appears in a posthumous edition of 1565. His account does not clearly place her in Strasbourg in the summer of 1518. Identifying her with the first dancer is a later inference, not the identity supplied by neighbours that July. The earliest dancer’s actions entered the record, but her name did not.

23 July: the council responds

On 23 July 1518, a commission of the city council issued deliberations catalogued at Strasbourg’s municipal archives as III 200/15. The same series includes instructions for sending affected people to the shrine of St Vitus at Hohlenstein, above Saverne in the Vosges. A Strasbourg museum exhibition gathered and translated these materials. Dated administrative acts establish that the episode happened; they do not automatically establish every detail added by writers centuries later.

Treatment followed contemporary understandings of the affliction. “St Vitus’s dance” was a label applied to different practices and conditions over time. In the Rhine region, pilgrims visited shrines associated with the saint; devotees could connect movement, prayer and relief. For officials, transporting people to a shrine and asking guilds to watch over members were practical forms of care and control. Reducing the entire episode to a city incapable of observation because of superstition misses the record.

25 July: a letter that complicates the idea of a curse

On 25 July, the council answered Bishop Wilhelm’s questions about the unusual illness. The letter survives under 12 J 1495 in the Bas-Rhin departmental archives. According to historical readings, officials said that the dancing had begun with one woman, that others followed, that those affected had been watched and that physicians had been consulted. The doctors described a natural disease linked to an astral configuration and seasonal heat: a theory of their time, not a valid modern diagnosis.

This is easily lost in modern retellings. Strasbourg’s officials did not simply declare demonic possession. Their letter combined observation, what counted as a natural explanation in 1518 and practical action; pilgrimage remained a religious response. Medicine and devotion coexisted. The dancing people, their families and the bishop might each have understood these measures differently.

2 August: banning public dance

The council altered course. An ordinance of 2 August 1518, signed by humanist and city secretary Sebastian Brant, banned public dancing and restricted instruments such as drums. The document is preserved as 1 MR 3, folio 72r. Later chronicles described stages in marketplaces, hired musicians and paid dancers helping sufferers “dance it out”. Those scenes chiefly come from later accounts, notably Daniel Specklin, and are not supported as firmly as the surviving order restricting dance.

A public ban does not reveal what caused the phenomenon. It shows that officials regarded the spectacle, the sound or the movement of groups as something they could regulate. Guilds were asked to care for their members. Reports of the episode diminish by late August and the following weeks; the fading record cannot tell us what happened to each dancer.

Fifty, two hundred, four hundred. And how many deaths?

The most repeated figures measure different things. The 1518 accounts emphasized by Clementz describe around fifty people. Later chronicles offer higher totals, including four hundred over several weeks; another gives roughly half that. No complete register of names allows a firm total or shows whether a figure refers to simultaneous or cumulative cases. The higher number belongs to a chronicle, not an unquestionable municipal count.

The death toll matters even more. Books and websites describe fifteen deaths a day, heart attacks and bodies in the streets. After examining near-contemporary texts and criticizing John Waller’s reconstructions, Clementz concludes that no contemporary author mentions deaths caused by the Strasbourg dance of 1518. Later writers, including Specklin, do mention deaths. That does not make deaths impossible; it does prevent us from stating their number or cause. “Dance of death” is a compelling title, not a recovered death register.

One event, many theories

Sixteenth-century physicians invoked heat and astral influence; pilgrims appealed to St Vitus; Paracelsus later offered a different account involving imagination and suggestion. In the twentieth century, ergot poisoning was proposed to explain movement and visions through a rye fungus. This is a retrospective hypothesis: no 1518 grain sample or exposure chain confirms it, and toxic convulsions do not by themselves describe weeks of socially patterned dancing.

John Waller argued for a collective response to hardship, expectation and shared belief. His interpretation is influential, but Clementz challenges both his placement of “Troffea” in Strasbourg and psychological scenes and deaths narrated without backing in the closest documents. Other scholarship foregrounds ritual dance, devotion, authority and the danger of attaching modern psychiatric diagnoses to unexamined people. A hypothesis can explain aspects of a context without becoming a medical finding for 1518.

The historical term “St Vitus’s dance” should not simply be equated with Sydenham chorea or Huntington disease. At different times those names were attached to involuntary movement; they do not establish that the people of Strasbourg shared either condition. The old term was broader and less stable than a modern diagnosis.

What the city left us

There is a concrete documentary trail: the 23 July deliberations, 25 July letter to the bishop and Brant’s 2 August ban. The Strasbourg museum exhibition dossier supplies shelfmarks and images of works used to study the period; no later engraving should be treated as a photograph of the outbreak. The documentary Les Danseurs Fous visits archives and interviews specialists, but its numbers also deserve checking against the documents.

The evidentiary boundary is clear. A collective dancing episode occurred and prompted action by Strasbourg’s government in 1518. The first woman’s identity, the precise number of participants, any single cause and the death toll have not been established by the records reviewed. The case is remarkable because we can watch a city attempt to observe, treat, regulate and explain something its language could barely contain, and because five centuries of retelling compel us to ask which document supports each detail.
