Faith and Madness

Justinian's 529 imperial edict prohibited pagans from teaching philosophy or law. Damascius — the last head of the Academy — closed the institution and led six other senior philosophers east to seek asylum at the Sasanian court of Khosrow I. They returned to Roman territory three years later under a clause of the 532 Treaty of Eternal Peace that guaranteed their legal protection. Theodosius I's 391 decree had earlier closed the pagan temples (the Serapeum at Alexandria was destroyed under it) but did not specifically close the Athenian schools.

The Saint Vitus shrine at Saverne in the Vosges was the recognised late-medieval European pilgrimage destination for *Sankt-Veit-Tanz* — Saint Vitus's dance — the religious-medical category for involuntary collective dancing afflictions. The Strasbourg authorities transported the surviving dancers in carts to the shrine over several weeks; the dancing substantively ended over the following month, probably more from the separation of affected individuals from each other and from the original triggering environment than from the religious intervention itself. Frau Troffea, the initial Strasbourg dancer, was not executed; her later fate is not documented.

The President's mistress Marguerite Steinheil was in the office; she escaped via a back staircase before the household discovered him. The official press release described the death as 'cerebral congestion' — true in the most literal possible sense. Faure's political project had been to consolidate French presidential authority, partly in opposition to the campaign to clear Alfred Dreyfus's name; his death within months of the case's climax was politically convenient for the Dreyfusard side. Steinheil resurfaced a decade later, on trial for two murders. She was acquitted.

Pope Clement VI banned the flagellants in the bull *Inter sollicitudines* on 20 October 1349. The movement had become a parallel religious authority distributing forgiveness without clerical mediation, and was increasingly anti-clerical and anti-Jewish in its public performances. The papal ban was substantively effective: the public movement collapsed across most of Europe within six months. Underground successor movements continued through the 14th and 15th centuries (Konrad Schmid's Thuringian heretics being the best-documented), but the public organised processions ended. Charles IV had no doctrinal authority. The Council of Constance was 65 years later (1414–1418).

Joan was captured by Burgundian forces in May 1430 and sold to the English. The English wanted her dead but needed cover, so she was tried by an English-aligned ecclesiastical court at Rouen on charges of heresy and cross-dressing. She was burned in Rouen's marketplace on 30 May 1431. She was 19. A 1456 retrial — convened by the king whose coronation she had made possible — formally rehabilitated her. She was canonised as a saint in 1920, almost 500 years later. The Spanish Inquisition was founded in 1478 and had nothing to do with her.

Wittenberg, in Saxony, was the small university town where Luther taught theology. The Castle Church (the *Schlosskirche*) had a notice-board door used for academic announcements; that's where the theses went, in standard Latin academic format. The nailing-to-the-door story is contested — the actual mechanism may have been mailing the theses to the archbishop — but the 31 October 1517 date is solid. The proceeds from indulgence sales Luther was protesting were being used to rebuild St Peter's. Cologne Cathedral is medieval but irrelevant; the Frauenkirche in Munich is 15th-century but had nothing to do with the Reformation.

Two confirmed survivors. **Louis-Auguste Cyparis** was a young black labourer in the city dungeon awaiting trial for assault; the thick stone walls of his underground cell shielded him from the worst of the pyroclastic flow. He survived for four days with severe burns before rescuers reached him. **Léon Compère-Léandre** was a shoemaker whose house sat on the extreme eastern edge of the city, at the limit of the surge's lethal range. Cyparis later joined Barnum & Bailey's Circus as a sideshow attraction; he died in the United States in 1929. Compère-Léandre stayed on Martinique and died there in 1936.

Hattin, on 4 July 1187. The Crusader army marched through Galilean summer drought to relieve Tiberias; Saladin manoeuvred them onto the waterless Horns of Hattin and destroyed them in a single day. Most of the surviving Templars and Hospitallers were executed; the captured True Cross was carted off. Jerusalem surrendered to Saladin in October. Manzikert was 1071, a century earlier. Damietta was a Crusader target in the Fifth and Seventh Crusades but never the decisive engagement. Acre's fall in 1291 was the end of the Crusader states — also significant, but more than a century after Hattin.

Nineteen people were hanged on Gallows Hill between 10 June and 22 September 1692. **Giles Corey**, the only American ever to die under *peine forte et dure* (heavy stones laid on the chest until death), was pressed to death on 19 September after refusing to enter a plea — he wanted his property to pass to his sons rather than be forfeit to the colony. Several additional accused died in prison awaiting trial. **No one was burned at the stake**: burning was a European punishment for witchcraft and heresy; the English-American colonial courts hanged. The trials ended in October 1692 when Governor William Phips dissolved the Court of Oyer and Terminer.

Synesius was made Bishop of Ptolemais in 410 AD by the Patriarch Theophilus of Alexandria — the same Theophilus who had destroyed the Serapeum nineteen years earlier. He accepted only on the explicit condition that he could keep his wife, his philosophical views (he did not believe in the literal resurrection of the body), and his hunting. He governed the see for three years before dying of an unidentified illness around 413. Hypatia was murdered by an Alexandrian mob two years later, in 415.

Urban II preached the First Crusade at the Council of Clermont. Gregory VII is the pope of the Investiture Controversy — he made Emperor Henry IV stand barefoot in the snow at Canossa in 1077. Innocent III, a century after Urban, was the pope of the catastrophic Fourth Crusade that sacked Constantinople in 1204 instead of going to Jerusalem. Clement V, two centuries later, was the Avignon pope who suppressed the Knights Templar in 1312.

Clement VI banned the *Brethren of the Cross* — the flagellants — in October 1349. The movement had grown into a parallel religious authority, distributing forgiveness without clerical mediation and producing several anti-clerical and increasingly anti-Jewish pogroms across the Rhineland in 1348–49. Clement himself spent the worst of the Black Death sitting in a chamber between two large fires on his physician's instructions and survived. Charles IV was the secular ruler of the Holy Roman Empire but had no jurisdiction over Catholic doctrinal questions. The Patriarch of Constantinople led the Eastern Orthodox church — separate institution since 1054. The University of Paris was a theological authority but did not issue binding decrees.

Maestlin was the senior Tübingen astronomer from 1583 to 1631. He officially taught the Ptolemaic system in public lectures and in his standard textbook, while privately teaching Copernicus to selected advanced students in tutorial. Kepler's 1596 *Mysterium Cosmographicum* — the first explicit Copernican defence by his generation — was dedicated to Maestlin. Melanchthon was a Lutheran reformer of the previous generation, died 1560. Tycho Brahe never went to Tübingen and was substantively hostile to Copernicus. Galileo was three years younger than Kepler and never taught him.

*Mass psychogenic illness* is the term preferred in current WHO and American Psychiatric Association literature. The older terms — *mass hysteria*, *collective madness*, *epidemic conversion disorder* — are now considered partially or wholly stigmatising. The clinical pattern is consistent across the seven-century case series: an outbreak of physical symptoms (dancing, twitching, fainting, laughing, etc.) that spreads through a connected social group under sustained collective anxiety or stress, cannot be explained by organic pathology, and self-limits when the affected individuals are separated from each other or from the triggering environment.

Heiberg traveled to the library of the Metochion of the Holy Sepulchre in Istanbul in 1906 after seeing a single photographic reproduction of a few pages of the prayer book. He identified the underwriting as Archimedean within hours, photographed substantial portions of the manuscript, and published the substantive content in 1910. The manuscript disappeared during the First World War, resurfaced at a Christie's auction in 1998, and was bought by a anonymous private collector for $2 million. The collector loaned it to the Walters Art Museum in Baltimore, where multispectral imaging recovered substantially more of the underwriting than Heiberg's photographs had captured. Schliemann excavated Troy, not Constantinople libraries. T. L. Heath translated Greek mathematical works but didn't find the palimpsest.

Picquart was transferred to Tunisia in January 1897 to keep him away from Paris; he continued to pursue the Dreyfus case from there through his Paris lawyer. He was eventually arrested on fabricated charges of mishandling intelligence material in September 1898 and held at the Cherche-Midi military prison for eleven months. The Henry forgery confession of August 1898 destroyed the Army's institutional position; Picquart was released without trial. He was rehabilitated, promoted to brigadier general, and on 25 October 1906 appointed Minister of War — the same day Dreyfus's final rehabilitation was pronounced. He died in 1914 in a horseback-riding accident.

The Strasbourg authorities concluded — on the standard humoral medicine of the day — that the dancing was caused by 'hot blood,' which could be cured by yet more dancing until the bad blood was expended. They hired musicians, built two large stages on the central squares, and contracted with several local guildhalls to admit the dancers. It didn't work; the dancing continued into September, several dozen people died of strokes, heart attacks, and exhaustion, and the city eventually reversed course and sent the dancers to the shrine of Saint Vitus in the Vosges instead. The modern medical consensus is mass psychogenic illness, possibly aggravated by ergotism.

The Tanganyika laughter epidemic of 1962 affected 14 schools in the Bukoba District over about 18 months and around 1,000 students. The standard modern medical diagnosis is *mass psychogenic illness* — a real condition with a long European history (the medieval dancing plagues, the early-modern convent crises, the 1518 Strasbourg episode). The episode was published in the *Central African Journal of Medicine* in 1963 by the Mwanza district medical officer and is the best-documented modern case. There was no organic cause; the affected children were physically healthy.

The Aachen outbreak of summer 1374 followed a major Rhine flood and was the largest documented medieval dance mania. Several hundred people in each affected city danced for days or weeks. Some danced themselves to death. The geographic spread up the Rhine corridor matched the trade-and-pilgrimage routes; the medical interpretations at the time ranged from demonic possession (the Catholic Church's official line) to organised heresy (a popular alternative) to ergot poisoning from contaminated rye (the modern medical revision). The 1349 date was the Black Death year — the Strasbourg dance was almost two centuries later.

Kepler personally took on his mother's case, returned from his observatory at Linz multiple times to represent her, and wrote the surviving 128-page legal brief in his own hand. She was acquitted in October 1621 after fourteen months of formal trial proceedings and six years of accumulated accusations. The trial documents — including Kepler's brief and the prosecution's catalogue of complaints from neighbours — are some of the most complete surviving records of a 17th-century German witchcraft case. Katharina died six months after the acquittal, broken by the imprisonment. Galileo never wrote about her. The Catholic Church had limited authority in Lutheran Württemberg.

Maimonides served Saladin's vizier Al-Qadi al-Fadil and later Saladin's son Al-Afdal. His *Guide for the Perplexed* (c. 1190) is the major work of medieval Jewish philosophy. Avicenna had been dead for 130 years by then (980–1037) and lived in Persia, never Cairo. Averroes was a contemporary of Maimonides — also from Córdoba, also a doctor — but he stayed in Andalusia and served the Almohad rulers there. Al-Razi (c. 854–925) was even earlier, the great Persian physician and freethinker.

12 Hz. The photosensitive-trigger band for inducing seizures runs from about 5 Hz to about 30 Hz; 12 Hz is squarely in the most-provocative range. Most of the 685 hospitalised children did not actually have photosensitive epilepsy and did not experience seizures — they had mass psychogenic illness propagated through evening news coverage of the original cases. About 80–100 of the 685 had genuine photosensitive seizures; the remaining 500–600 had MPI. The TV Tokyo network suspended *Pokémon* for four months. International broadcasting standards subsequently limited flash rates to a maximum of three per second.
