The Beast of Gévaudan: what really killed people in 1760s France?

What happened in the Gévaudan, 1764–1767

The Gévaudan was a remote, poor upland province of south-central France, roughly today's Lozère. From June 1764 to June 1767, people there and in the neighbouring Vivarais, Rouergue and Auvergne were attacked by an animal, or animals, that the press called simply the Beast. The first recorded death, in June 1764, was a 14-year-old girl watching livestock. Most of the dead were women and children; in that pastoral country, minding the animals was often a child's job, done alone.

How many died depends on which attacks are counted. Graham Robb, summarising the record in the London Review of Books, puts the toll at about 60 by the end of 1765. National Geographic gives as many as 100 for the whole episode and notes that some sources go as high as 300. Whatever the figure, the attacks themselves are not legend: they are documented in official reports and letters and in the newspapers of the time, which is why historians treat them as fact.

The popular claim: a monster, a werewolf, a hyena

What made the Beast famous was the press. The Courrier d'Avignon alone printed 98 articles on it in 13 months; the Paris press followed, and the Public Domain Review counts the affair among the first news stories to go international. Beast of Gévaudan sightings were turned into posters and prints: a 1764 poster described a reddish creature as big as a donkey, a print compared it to a young bull, and another argued it was a hyena. The Seven Years' War had just ended, and a beast that nobody could kill became a national embarrassment. A dragoon captain, Jean-Baptiste Duhamel, raised thousands of local people for hunts in the autumn of 1764 and failed. Louis XV put up a reward worth about a year's pay for an ordinary man, sent the Normandy wolf hunter Jean-Charles d'Enneval in 1765, and finally sent his own lieutenant of the hunt, François Antoine.

On 20 September 1765 Antoine's party shot a large wolf near the royal abbey of Les Chazes. It was stuffed and shown at Versailles, and the court treated the matter as closed. The killings resumed within months. On 19 June 1767, during a hunt organised by the local Marquis d'Apcher, a hunter named Jean Chastel shot a big animal, and the attacks stopped. The silver bullet often credited to Chastel is a rumour, not a record.

The scientific explanation: Beast of Gévaudan evidence

So what was the Beast of Gévaudan? Neither body survives. What does survive are written descriptions, including a surgeon's examination of the Chazes wolf, recorded on 27 September 1765, and an official report on Chastel's animal dated 20 June 1767. In 2024 François-Louis Pelissier of the Muséum départemental du Var in Toulon compared those descriptions with modern measurements of wolves and dogs. Both animals had the dentition of a canid: the reports count 40 teeth in the Chazes animal, with two missing, and 42 in Chastel's. The main shearing teeth recorded for the 1767 animal are far bigger than any dog's in his comparison data and bigger than those of the modern wolves too; their nearest match is the giant wolves of the late Ice Age. The records put its weight at 109 livres, about 53 kilograms. Pelissier concludes that both were probably wolves, the 1767 animal most firmly.

That fits the historians. The historian Jay M. Smith, whose book Monsters of the Gévaudan was published by Harvard University Press in 2011, attributes the attacks to several large wolves. The Public Domain Review calls this the majority view among historians, borrowing Robb's description of the province as "infested with wolves". Pelissier adds that predatory wolf attacks on people, while very rare in France today, are documented elsewhere, in Italian records from the 15th to the 19th century and in 20th-century India, and that the injuries described in the Gévaudan match what wolves do.

What is still debated

Three things. The first is how many animals were involved. The killing went on after the 1765 wolf was shot, and the area covered was large; National Geographic notes that the spread of deaths may point to a pack, and Pelissier says the estimates, though contested, imply more than two animals.

The second is whether any of them was a wolf-dog hybrid. Several authors have argued for a hybrid, and Chastel's animal had at least one feature that can hint at mixed ancestry: a large heart-shaped white mark on its chest. Pelissier finds no combination of features that robustly supports the idea, but says it cannot be ruled out, because no remains survive to test it.

The third is a fringe of more exotic answers. The biologist Karl-Hans Taake has argued for an escaped young lion. Others have proposed a trained hyena, armoured thylacines, an extinct prehistoric carnivore, or a human killer working with an animal, which National Geographic says most experts consider too far-fetched. Since both examination reports describe the teeth of a canid, they tell against a cat or a hyena.

Common questions

Verdict

Was the Beast of Gévaudan real? Yes, and the Beast of Gévaudan explained comes down to one line: the killing was real, and the killers were animals, almost certainly wolves. The attacks are documented from 1764 to 1767; the two animals described in detail in official reports were canids, and the best available comparison of their teeth and bones points to unusually large wolves. What made them a beast was an eager press, an embarrassed monarchy and a frightened countryside. Real or Legend stamps this record confirmed: confirmed that the attacks happened and that real predators, not a monster, were responsible. How many wolves there were, and whether one was part dog, remains open.
