There is a category of historical death that I would describe as "too specific to have been invented by a later chronicler." The general pattern of a general pattern death, the drowning, the poisoning, the battlefield wound, can be embroidered later by the tradition. The very specific cause of death, including the kind of detail that would not occur to a hagiographer inventing a more meaningful exit, tends to be more reliable. What follows are seven deaths that fall into this category. Each of them is attested by contemporary or near-contemporary sources. None of them is the kind of death anyone would invent on purpose.
1. Aeschylus (died 456 BC, by tortoise)
The Athenian playwright Aeschylus, author of the Oresteia and one of the three great tragedians of the classical period, died at Gela in Sicily in 456 BC. The circumstances, according to Valerius Maximus, Pliny the Elder, and the Byzantine encyclopedist the Suda, were as follows: an eagle, having caught a tortoise and needing a hard surface on which to drop the animal to break its shell, mistook the playwright's bald head for a suitable rock. Aeschylus was killed by the impact.
The story is plausible. Lammergeyer vultures, which are present in the Mediterranean, are in fact documented as habitually dropping tortoises on rocks to crack the shells. The birds do occasionally mis-identify pale objects as rocks. Aeschylus is reported by other sources to have been bald. Whether this specific incident is what killed him is of course not something we can now verify. What can be said is that his contemporaries and near-contemporaries, who would have had every reason to invent a more dignified death for one of their cultural heroes, did not do so. The tortoise is, in that sense, evidentiary.
2. Heraclitus (died c. 475 BC, by dung)
The pre-Socratic philosopher Heraclitus of Ephesus, famous for the doctrine of universal flux and for being, by the accounts of his contemporaries, almost impossible to live with, retired in his later years to a mountain in Ionia where he subsisted on plants. He developed dropsy — in modern terms, probably congestive heart failure producing edema. According to Diogenes Laërtius, he consulted the local physicians by posing them a riddle rather than asking directly for treatment. They failed to solve it. Heraclitus then treated himself by burying his body in cow dung, on the theory that the heat would draw out the excess moisture.
Reports differ on what happened next. One version has him unable to extract himself and eaten by dogs. Another has him simply dying from the combination of the illness and the treatment. Either way, the specific detail of the self-treatment by dung burial is the kind of thing that no admirer would have invented. Diogenes Laërtius was writing centuries after Heraclitus, but he was drawing on local traditions that had little motivation to produce this particular story.
3. Attila the Hun (died 453 AD, by nosebleed)
Attila, king of the Huns and at the time of his death the most feared military figure in Europe, died on the night of his wedding to a Germanic woman named Ildico, in his encampment on the Hungarian plain. According to the Gothic historian Jordanes, writing in the 550s from earlier sources, Attila had been drinking heavily at the wedding feast. He retired to the bridal tent with Ildico. In the morning, when his guards became concerned that he had not emerged, they broke in. Attila was dead in the bed, covered in blood. Ildico was sitting in the corner, weeping, uninjured.
The specific medical cause, according to Jordanes, was a ruptured blood vessel in the nose. Attila, drunk and lying on his back, had drowned in his own blood. The modern reading, which tends to credit the account, is that an esophageal varix or a peptic ulcer hemorrhage was the actual cause. Attila's heavy drinking is well-attested. The specific mechanism — drowning in blood from a nosebleed on one's wedding night — is not the kind of death a Gothic historian would invent for a feared Hunnic king. They would give him a battlefield. They did not.
4. Sigurd the Mighty (died c. 892 AD, by severed head)
Sigurd Eysteinsson, the second Earl of Orkney, fought a successful campaign in northern Scotland against a local chieftain named Máel Brigte. According to the Orkneyinga saga, composed approximately three centuries after the events but drawing on earlier oral tradition, Sigurd tied Máel Brigte's severed head to his saddle as a trophy. Riding home, the head jolted against Sigurd's leg. One of Máel Brigte's teeth, which protruded from his mouth, cut Sigurd's calf. The wound became infected. Sigurd died within weeks.
The saga is not a contemporary document, and there is a reasonable argument that the story is embellished. But the mechanism, tetanus or septicemia from a puncture wound caused by a dead mouth, is medically plausible. It is precisely the kind of infection that would have been untreatable in the period. The detail of the tooth is specific enough that it is hard to read it as pure invention. If a saga-composer wanted to make Sigurd's death meaningful, a battlefield death would have served better than a posthumous tooth.
5. King Charles II of Navarre (died 1387, by accidental ignition)
Charles II of Navarre, known in his own lifetime as Charles the Bad for reasons having to do with his political conduct rather than his death, was in declining health in the mid-1380s. His physicians prescribed a treatment of the period: linen bandages soaked in brandy and sulfur, wrapped around the king's body to warm his limbs. One night in January of 1387, an attendant using a candle to sew up a stray thread at the edge of the bandaging allowed the flame to touch the brandy-soaked cloth. The bandages ignited. The king was wrapped in them.
He survived the initial burning but died several days later, on January 1, 1387, from the injuries. The event is well-attested in Navarrese court records and in the Chronique du Religieux de Saint-Denys. The specificity of the mechanism (brandy, sulfur, candle, linen, attendant) is exactly the kind of detail no chronicler would fabricate. It is also a rare case where the medical treatment of the period was the immediate cause of death, which happened somewhat more often than the surviving records admit.
6. Franz Reichelt (died February 4, 1912, by coat-parachute)
Franz Reichelt was an Austrian-born tailor living in Paris who believed he had designed a garment that would function, in flight, as an effective parachute: a kind of long coat that would deploy into a canopy when the wearer fell. He had tested the design successfully, by his own account, on mannequins dropped from shorter heights. He had been denied permission by the Paris police to conduct a full-height test at the Eiffel Tower and had been dissuaded by friends and by his own earlier assistants from making the attempt personally.
On the morning of February 4, 1912, he arrived at the tower with permits that it is not clear he actually held. He brought with him two newsreel cameras and a Pathé photographer. He had told the authorities that he would be testing with a mannequin. On the platform, at the level of approximately 57 meters, he announced that he would be making the jump personally. He hesitated for approximately forty seconds. He jumped. The coat did not open. He struck the ground approximately five feet from the base of the tower and made a crater several centimeters deep. He was killed instantly.
The footage is extant. The newsreel cameras captured the entire jump. It is, as far as I am aware, the only documented case of a self-testing inventor's failed parachute fatality preserved in motion film. The film is widely available online. Viewers are warned.
7. Isadora Duncan (died September 14, 1927, by scarf)
Isadora Duncan, the American-born dancer who was in her lifetime one of the most famous performers in Europe, was fifty years old and living in Nice in the autumn of 1927. On the afternoon of September 14, she got into an Amilcar CGSS sports car, driven by a French-Italian mechanic named Benoît Falchetto, for what was apparently a test drive she was considering purchasing. She was wearing a long, hand-painted silk scarf, described by her friend Mary Desti as being of a length of approximately two meters. As the car accelerated, the trailing end of the scarf caught in the spokes of the rear wheel. Duncan was pulled violently from the seat. Her neck was broken instantly.
The event was covered extensively in the international press. Falchetto was not charged. The accident is often cited, perhaps unfairly, as an emblematic case of a life ended by its own theatrical apparatus. Duncan had once written, of her style of dress and its characteristic scarves, "Adieu, mes amis. Je vais à la gloire!" ("Farewell, my friends. I go to glory!") She was reported to have used this phrase, or something close to it, as she got into the car that afternoon. This specific last-words report may or may not be accurate (see elsewhere in this archive regarding the reliability of famous last words). The scarf is documented.
And the one that almost got invented
There is a eighth case I want to mention briefly, which is Pope Adrian IV, who is often said in popular accounts to have choked to death on a fly in a glass of wine in 1159. This is a story that appears in a few medieval sources, but the most reliable contemporary account, that of William of Newburgh, attributes his death to quinsy (a tonsillar abscess). The fly, plausibly, was added later — perhaps as a way of making a relatively undramatic death more memorable.
The distinction between the seven above and the Adrian story is that the seven are each attested with specificity that an inventor would not have supplied, while the Adrian fly is exactly the kind of detail an inventor would supply. The fly is symbolically resonant: the Pope brought low by a small thing, the mighty undone by the tiny. The turtle, by contrast, or the nosebleed, or the scarf in the wheel: these are too specific and too anticlimactic to be doing that kind of literary work. They are, as far as the historical record goes, what actually happened. Which is, in the end, often stranger than the stories we make up about it.
