The Black Death, and The Dancing Mania

In Short

This foundational work of historical pathology examines two distinct yet related phenomena: the 14th-century bubonic plague and the subsequent, centuries-long outbreaks of compulsive dancing. By synthesizing contemporary chronicles, medical observations, and environmental records, the author argues that mass psychological distress, religious fanaticism, and environmental shifts create "epidemics of the spirit" alongside biological ones. It has remained a significant study because it treats disease not merely as a clinical event, but as a reflection of the human condition, social structure, and the collective psychology of the Middle Ages.

The Story

The narrative begins with the catastrophic arrival of the Black Death in the mid-14th century, tracing its path from the Levant to Europe through the accounts of contemporary observers. The plague serves as the primary engine of the book’s opening act, illustrating how a biological contagion dismantled the social fabric. The author details the harrowing symptoms—spitting blood, rigor, and the eventual appearance of buboes—that decimated populations from London to Russia. He describes a world where the natural order seemed inverted, marked by failed crops, violent earthquakes, and meteors that fed a climate of apocalyptic terror. As the death toll climbed into the hundreds of thousands, the author captures the resulting moral collapse, showing how the fear of infection dissolved family bonds and prompted a desperate, often misguided, religious fervor.

From this foundation of collective trauma, the narrative transitions into the rise of the "dancing mania," or chorea. The author details how, in the wake of the plague’s devastation, entire populations became gripped by an uncontrollable impulse to dance, often lasting until the victims collapsed from exhaustion. He links these outbreaks to the festival of St. John the Baptist, suggesting that the "half-heathen, half-Christian" customs of the era provided the tinder for this psychological fire. The mania, he argues, was not merely a physical malady but a manifestation of deep-seated societal repression and religious hysteria.

The book then explores the specific variant known as tarantism in Italy, which local tradition attributed to the bite of a spider. The author systematically debunks the biological necessity of the spider bite, repositioning the phenomenon as a nervous disorder exacerbated by the social isolation of women and the influence of music. He chronicles the bizarre behaviors associated with the mania, such as an obsessive, violent attraction to specific colors—where a patient might suffer if deprived of a red cloth—and the eventual easing of symptoms through music and dance.

The arc concludes by comparing these historical eruptions of mass hysteria to more modern manifestations, including the "Barkers" and "Jumpers" observed at 19th-century American camp meetings. The author argues that regardless of the era or geography—whether in medieval Germany, Renaissance Italy, or the American frontier—the underlying mechanics of human contagion remain constant. The book ends on a somber, reflective note, suggesting that while science has advanced, the susceptibility of the human mind to collective frenzy and the "proteiform" nature of nervous disorders remain an enduring, if sobering, aspect of the human experience.

How It Unfolds

The arrival of contagion The author tracks the plague’s relentless march across Europe, emphasizing its "unexampled rapidity" and the resulting depopulation. He highlights the breakdown of civic life, as even the most sacred social ties crumbled under the weight of inevitable mortality.

The moral and religious response The narrative pivots to the psychological toll, documenting how the terror of the Black Death birthed both profound acts of charity and irrational violence. He details the tragic persecution of Jewish communities, who were scapegoated for the disaster through false accusations of poisoning the wells.

The emergence of the dancing mania Shifting to the aftermath, the author examines the involuntary, convulsive movements that seized the populace of Aix-la-Chapelle. He proposes that these outbreaks were a psychological byproduct of the "barbarous enthusiasm" and religious superstitions that defined the era.

The tarantism and the role of the senses The focus narrows to the Italian experience, where the author analyzes the intense, often eroticized, sensory cravings of the dancers. He demonstrates how these movements allowed the socially marginalized, particularly women, to find a cathartic release from their "miserable existence."

The synthesis of historical trauma In the final sections, the author draws parallels between medieval flagellants and modern religious revivals. He concludes that these phenomena are not mere historical curiosities, but consistent responses to periods of intense social, environmental, and spiritual instability.

The People

The book focuses less on individual protagonists and more on the collective "person" of history. The physicians of the 14th century emerge as central, though conflicted, figures. They struggle to reconcile the limitations of their medical knowledge with the undeniable reality of the plague, often relying on the era's prevalent astrological beliefs to explain the "astral influence" of planetary conjunctions. Though the author views their methods as outdated, he defends their intellectual integrity, arguing that they were as limited by their time as modern doctors will eventually be by theirs.

The suffering populace acts as the primary collective subject. Whether they are the terrified merchants casting their gold over convent walls or the hysterical dancers in the Italian streets, these figures are driven by a need to find meaning in an environment of total collapse. The women of Italy are highlighted as particularly significant; the author paints a sympathetic portrait of their "lonely" lives, suggesting that their participation in the dancing mania was a subconscious revolt against their lack of social agency. Finally, the figure of Paracelsus serves as a bridge between the medieval and the modern. As a physician who attempts to treat the mania with a mix of harsh discipline and psychological insight—such as the "mental remedy" of burning a wax effigy—he represents the transition toward understanding that the seat of such maladies is as much in the "heart and imagination" as in the body.

In Its Own Voice

"The mental shock sustained by all nations during the prevalence of the Black Plague is without parallel and beyond description."

The author sets the stage for his argument that the plague’s impact was as much psychological as it was biological.

"A nervous disorder that had arrived at so high a degree of development must have been long in existence, and doubtless had required an elaborate preparation by the concurrence of general causes."

This observation encapsulates the author’s theory that epidemics are the result of long-gestating social and environmental pressures.

"The 'Carnevaletto delle Donne' appeared most opportunely for those who were hysterical."

The author explains how the structures of Italian society provided a specific, ritualized outlet for the internal frustrations of women.

What It's Really About

The central argument posits that human health is inextricably linked to the state of civilization. The author contends that "epidemics" are not merely localized biological events but are instead "proteiform"—taking different shapes depending on the cultural, social, and spiritual environment of the age. He explores the tension between the physical body and the "all-conquering imagination," suggesting that when a society is subjected to extreme, prolonged stress, the collective nervous system becomes hypersensitive. The question underlying his inquiry is whether human nature has truly changed; he challenges the reader to consider if our own modern reactions to crisis are fundamentally different from the "barbarous enthusiasm" or the "superstitious horror" of the medieval period, or if we are merely wearing different masks for the same underlying human vulnerabilities.

Why Read It Today

Readers interested in the history of medicine, psychology, or the sociology of disaster will find this book remarkably prescient. The author writes with a blend of scientific curiosity and deep empathy, avoiding the clinical coldness that often characterizes historical medical texts. He approaches the "dancing mania" not with derision, but as a genuine puzzle of human psychology, treating the dancers as people struggling under the weight of their own era.

However, the reader should be prepared for the dense, 19th-century prose style. The author often relies on long, winding sentences and, at times, archaic medical classifications that require patience to navigate. The excerpts also reflect the period’s specific preoccupations, such as the reliance on astrology or the somewhat detached, analytical lens through which he views the suffering of the past. Despite these challenges, the book rewards the reader with a profound sense of continuity. It serves as a mirror for the present; while the specific "epidemics" of our age may differ, the author’s insistence that our bodies and minds are deeply responsive to the "general life which diffuses itself throughout the whole universe" feels as relevant today as it did when the book was first compiled. It is a work that reminds us that we are all, to some degree, products of the historical and social weather in which we live.
