Certainly, had Dr Clarke been stung by the furia
infernalis at the moment that he expressed his disbelief of its existence, one
would be almost tempted to think that the worm possessed, along with its other
infernal attributes, that of knowledge, and had punished the Doctor for his
scepticism.
Henry D.
Inglis - A Personal Narrative of a Journey Through Norway, Part of Sweden, and the
Islands and States of Denmark
Can a tiny
creature that doesn't even exist inflict agonising pain and even death upon its
human victims? Ordinarily, I would say no - but the history (and mystery) of
the virtually forgotten yet decidedly bizarre micro-assassin documented here is
anything but ordinary.
Carl von Linné
(1707-1778), or Carolus Linnaeus, the Latinised version of his name by which he
became known throughout the scientific world, was the Swedish botanist who
famously devised the Linnaean nomenclatural system of classification by which
all species of organism are given a formal binomial name, and are categorised
in an ascending series of taxonomic echelons, from species, genera, and
families, up through orders, classes, phyla (though this particular echelon was
not among his originals), and kingdoms. However, a bizarre incident that
occurred one day early in his career almost brought it, and, indeed, his entire
life, to a premature end, and resulted in his making a rare but significant
error.

In 1728, while
still a student, an impoverished Linnaeus was lodging at the home of the
eminent Swedish scientist Kilian Stobaeus, professor of physics and botany at the
University of Lund, but he was keen to amass his own herbal, so he spent much
time out in this region's marshes, collecting and classifying botanical
specimens. On the fateful day in question, Linnaeus was visiting an area just
outside Lund in search of more specimens when suddenly he felt something sting
his neck.
Rather than assuming
the unseen culprit to be some type of insect, however, Linnaeus later deemed it
to be a tiny slender worm, because he had been made aware of such a creature
from local rural lore. Although it did not appear to have a specific name, this
worm was said to be carried on the wind from overhanging vegetation, was
extremely venomous, and was armed with a spike at one end that injected the
venom, after which the worm swiftly burrowed deep within its victim's flesh,
the combined effects of its venom and its burrowing activity resulting not only
in agonising pain but actual death if not treated rapidly.
And sure enough, within a very short space of time Linnaeus's neck and also one
arm had become so greatly inflamed, with the supposed worm apparently buried too
deeply in his flesh for him to extricate it, that by the time he had managed to
make his way back home his very life had become severely endangered. Happily,
however, the swiftly-administered expertise of Stobaeus and a physician called
Dr Schnell – who incised Linnaeus's arm from armpit to elbow - proved
sufficient to quell the worm's dire effects, and Linnaeus recovered.

Naturae, 10th edition, 1758, title page (public domain)
Nevertheless,
the experience had such a profound effect upon him that when he published in
two volumes (in 1758 and 1759 respectively) the tenth, ground-breaking edition
of his taxonomic magnum opus, Systema Naturae, Linnaeus included a
formal description and exceedingly apt binomial name for his diminutive but
deadly vermiform assailant and would-be assassin. He dubbed it Furia
infernalis, the hellish fury worm, after the Furies.
Also known as
the Erinyes, these were a terrifying trio of ancient, Underworld goddesses from
Greek mythology that meted out merciless vengeance, relentless punishment, and inescapable
retribution to sinners on Earth until they finally died in torment. The
best-known story featuring the Furies is their persecution of Orestes (a
dramatic scene captured by several artists down through the centuries), after
he had killed his mother Clytemnestra following his shocking discovery that she
had murdered his father Agamemnon, the king of Mycenae and leader of the
combined Greek forces during the Trojan War, after he had returned home to
Greece following the end of the war.

Included within
the Vermes (Worms) section of his work, Linnaeus's description in Latin of Furia
infernalis reads in English as follows:
Body thread-like, of equal thickness throughout. On
both sides of its body it has a single row of closely-pressed recurved stings.
Habitat: northern marshes of Bothnia and Sweden. Worst
of all: falling from the sky onto the bodies of animals, it quickly penetrates,
killing with atrocious pain within a quarter of an hour.

Bearing in mind
that he had not actually seen the worm that attacked him, however, how could
Linnaeus provide such a precise if concise morphological description of it? In
fact, he based his account on two entirely separate sources. One of these
(referenced by him in his account) was a then-unpublished paper on the fury
worm, again written in Latin, but authored this time by a former pupil,
naturalist Dr Daniel C. Solander, which utilised testimony from various local
victims of supposed fury worm attacks as well as traditional rural lore
concerning it.
Solander had originally
submitted his paper to Acta Upsaliensia (the transactions of the Royal
Society of Sciences at Uppsala Academy) during the 1750s, but due to a break in
the publishing of this journal that lasted from 1751 to 1772 it did not appear
in print until 1773, within the inaugural volume of the rebooted Nova Acta Regiae
Societatis Scientiarum Upsaliensis.

Linnaeus's
second source of information was a local peasant. This was the person who had told
him that the cause of his injury had been a specific type of worm, one that is
carried on the wind and penetrates the flesh of anything that it lands upon.
Moreover, this same peasant subsequently brought to him a dead specimen of a
tiny vermiform creature that he claimed was one such worm. However, the
specimen was so dried and desiccated that its taxonomic identity is unlikely to
have been readily discerned, and it does not appear to have been retained, so
no modern-day reappraisal of it is possible.
The respective
publications of Linnaeus and Solander attracted appreciable interest in the
scientific world, especially in view of Linnaeus's eminent standing by then and
his direct experience with this small but potentially lethal creature. As a
result, a wide range of additional publications featuring it began to appear,
some of which provided interesting local information as well as additional
accounts from persons claiming to have been victims of its formidable actions –
as now presented here in what is the most comprehensive documentation of the
fury worm ever compiled.

Scriven after J. Opie, 1825 (public domain)
The fury worm
was supposedly native to northern Sweden, Lapland and Bothnia (both of these regions
being shared between Sweden and Finland), and Russia. One of the most
remarkable cases supposedly involving this creature featured the famous English
traveller-naturalist Dr Edward D. Clarke, due to the extraordinary coincidence
that formed part of it, as recorded by Clarke in his multi-volume opus Travels
in Various Countries in Europe, Asia and Africa (1810-1819). Journeying
towards the Swedish town of Sundswall in late June 1799:
A remarkable circumstance happened to the author, just before his
arrival at this place [Sundswall], upon the first of July. He had been reading the
life of Linnaeus, in the open travelling waggon, as he
proceeded on the route; and was giving an account to his companion of the
marvellous manner in which that celebrated naturalist had nearly lost his life,
in consequence of being wounded by a worm, said
to have fallen from the air — Furia infernalis; expressing, at the same
time, his incredulity, as to the existence of such an animal, and, of course,
his disbelief of the fact. At this moment, he was himself attacked in the same
extraordinary manner, and perhaps by the same creature. A sharp pain, preceded
by slight irritation, took place in his left wrist. It was confined, at first,
to a small dark point, hardly visible; and which he supposed to proceed from
the sting of a gnat. Presently, it became so severe, that the whole of the left
arm was affected, quite to the shoulder, which, as well as the joints of the
elbow and fingers, became benumbed. The consequence might have been more
serious, if he had not resorted to a mode of cure pointed out by the inhabitants;
namely, a poultice of curd; to which he added the well-known Goulard
lotion, prepared from the acetite of lead.
(Cheese or curd
poultices are traditionally claimed to reduce inflammation - but although this
has not been scientifically confirmed, modern-day athletes have been known to
resort to using them in the treatment of such conditions.)
Reindeer,
a sizeable herd of which was supposedly killed by Furia in 1823 (public
domain)
Nor were humans
the only victims of the injurious if invisible fury worm. In a paper surveying
this mystifying mini-beast, published by the Edinburgh New Philosophical
Journal in 1827, Arthur de Capell Brooke claimed:
It appears, that the Furia does not confine its attacks to
the human race, but that cattle, and the rein-deer in particular, are exposed
to it. In 1823, the Laplanders are stated to have suffered so greatly in their
herds, that 5000 head died from the sling of this creature; and that even the
wolves and other animals, that preyed upon the dead carcases, caught the
infection, and died with the same symptoms. A Laplander, who possessed 500
deer, on perceiving the destruction among them, thought it best to kill the
whole herd; but so quickly did its ravages spread, that, before he could
accomplish his purpose, they all died. Great numbers of cattle and sheep were
likewise destroyed by its attacks, and it fell, in some degree, upon the human
species, a few having become victims to it. A young girl, who was shearing some
sheep, that had died from the attack of the Furia, felt, while thus
employed, a sudden pain in one of her fingers, which rapidly increased, and, on
examining the part, she found a small puncture like the prick of a needle; her
master, who was by, had the presence of mind to cut the finger off on the
spot, and it was the means of saving her life.
The pest is stated to have been confined to Russian and Swedish
Lapland, and did not spread higher than Muonioniska. Norwegian Lapland
fortunately was not visited with this calamity; and, in order to prevent it
from being introduced, all furs, during the year of its prevalence, were
forbidden to be purchased*.
(*I have since ascertained, that, in consequence of the alarm excited
by the reported ravages of the Furia, an edict was actually issued from
the Amtmand [Ambassador] of Finmark [a county of Norway], prohibiting the
introduction of all furs into the country during that year.)
Back in 1804,
the Reverend William Bingley had included the following details in Vol. 3 of
his Animal Biography:
Only one species [of Furia], the Furia
infernalis, has been hitherto discovered. In Finland, Bothnia, and the
northern provinces of Sweden, the people were often seized with an acute pain,
confined to a mere point, in the face, or other exposed part of the body, which
afterwards increased to a most excruciating degree, and sometimes, even within
a few hours after its commencement, proved fatal. This disorder was more particularly
observed in Finland, especially about marshy places, and always in autumn. At
length it was discovered that the pain instantly succeeded something that
dropped out of the air, and almost in a moment penetrated and buried itself in
the flesh. On more accurate attention, the Furia was detected as the cause. It
is about half an inch in length, and of a carnation colour, often black at the
apex. It creeps up the stalks of sedge-grass, and shrubs in the marshes, whence
it is often carried off by the wind; and if the naked parts of the skin of any
person happen to be directly in its course it immediately adheres, and buries
itself within. The first sensation is said to be like that arising from the
prick of a needle, this is succeeded by a violent itching of the part, soon
after acute pain, a red spot and gangrene, at last an inflammatory fever,
accompanied with swoonings. In the course of two days, at the farthest, death
follows, unless the worm be extracted immediately, which is very difficult to
be done. The Finlanders say, however, that a poultice of curds, or cheese, will
allay the pain, and entice the animal out. Perhaps the most effectual method
is carefully to dissect between the muscles where it had entered, and thus
extract it with the knife.
This is a
particularly notable account inasmuch as it includes not only a very
eyecatching body colouration (carnation) for the fury worm but also a size for
it (half an inch) that if accurate should again be readily visible to the naked
eye. Yet in spite of that, eyewitness descriptions of this creature were generally
conspicuous only by their absence. Nor does there appear to be a single illustration of a fury worm dating back to the time when it was being reported. Clearly, something was very amiss here, and it would not be much longer before scientists began to realise this, and to reflect upon the Furia case in a new and more discerning manner, as will be seen.
Portrait
of Prof. Peter S. Pallas by Tardier (public domain)
In 1800, an
extensive account on the subject of Furia as originally written by no
less an authority than the eminent German-born Russian zoologist and botanist
Prof. Peter S. Pallas had been reprinted in the Philosophical Magazine,
edited by Alexander Tilloch. The most important section of Pallas's account, also
featuring some of the afore-mentioned Dr Solander's findings concerning the
fury worm as given in his Latin paper, reads as follows:
According to his observations, the extensive fens in
the northern part of Bothnia are the principal seat of this destructive insect,
and the tumours it produces have been remarked chiefly by the inhabitants of
these districts or those who travel through them. In men, this disease
generally attacks those parts of the body which are exposed to the air, such as
the hands, arms, neck, etc. A prick like that of a needle is first felt, after
which a black speck is seen in the place, and a violent itching ensues. This is
soon after followed with extreme pain, a red spot is produced, and the neighbouring
parts are inflamed. As the disease increases, the parts become more irritated
and painful, and the patients are seized with an inflammatory fever,
accompanied with fits of fainting and delirium, which, often carries them off
in the course of a few days, and sometimes of a few hours. Some, however, get
over this fever, but are affected in the injured part with malignant and tedious
sores, which often remain incurable during their whole lives.
Dr. Solander was himself an eye-witness of a case of
this kind, and he mentions others which were related to him by persons worthy
of credit. The greater part of them occurred in the spring and summer, though
instances of this disease have been observed in winter. When the worm has penetrated
into the flesh, it is often impossible to save the patient even by cutting out
the affected part; but it sometimes happens that the small animal which is the
cause of the evil may be extracted with a pair of pincers, or the teeth, if the
proper means be employed immediately after the puncture is felt. When this is
done by cutting, the patient, if the worm has penetrated to a great depth, is
exposed to the most excruciating pain. Old women, who perform the operation of
cutting the flesh or extracting the worm with a variety of superstitious
practices, are accustomed to apply birch-tar to the wound, and then to bind it
up. In one case, the worm was extracted by the accidental application of
curdled milk or new cheese, and the patient cured in the course of six hours.
This remedy was afterwards repeated with success. When the patient dies, the
destructive insect, it is said, comes forth of its own accord from the
mortified part.
But in whatever manner it may come forth, it has
always the appearance of a very tender small worm, of the size of a hair, about
half an inch in length, of a flesh or whitish yellow colour, and often black
at the extremities. On each side it is armed with a single row of uncommonly
tender bristles standing backwards, which enable it to penetrate the flesh better;
and in all probability these bristles occasion that acute pain which is felt,
and prevent it from being extracted. No rings or indentations can be observed
on it; and, except the bristles, it has a great resemblance to the hair-worm.
This is the singular animal which Linnaeus has
admitted into his system under the very proper name of the Furia infernalis.
It is however hardly possible to suppose, with this naturalist, that the above
worm falls down from the atmosphere; for it will be difficult to explain by
what power it can raise itself into the air. But the wonder will cease if we
suppose that this worm may be borne aloft on bits of straw or the leaves of
trees, and may then be conveyed by the winds till it at length falls down on
the body of some animal.
In Pallas's
account, the terms 'insect' and 'worm' were used interchangeably, so 'insect'
was clearly being employed in a generic, non-entomological sense there.
However, the
tide of scientific opinion would soon be turning away from a vermiform identity
and toward some type of bona fide insect as the explanation for the malign yet
mysterious Furia, and one much-publicised case that greatly promoted
this change of heart was the following one. It appeared in a travelogue
entitled A Personal Narrative of a Journey Through Norway, Part of Sweden,
and the Islands and States of Denmark, first published in 1829 and whose
author originally used the pen-name Derwent Conway. In a later edition,
appearing in 1837, however, he reverted to his real name, Henry D. Inglis. After
documenting Dr Edward D. Clarke's injury supposedly caused by Furia back
in June 1799, Inglis presented a very pertinent observation of his own, made by
him during his journey through Norway:
Sitting one day, along with a peasant who had been my
guide to a trouting stream, upon a trunk of a tree, in some boggy ground,
covered with coarse grass, and here and there a few cranberry bushes, I saw a
very small fly of a gray colour, suddenly light upon the back of my companion's
hand, and as suddenly fall off. Immediately after he lifted up his hand,
complaining of acute pain; and there appeared a small blackish speck where I
had seen the insect alight. He immediately said he was bitten by a worm, and
made the utmost speed to reach a house where he might have a curd-poultice
applied. The hand and arm swelled and were much inflamed, and the man cried out
with the excessive pain. The moment I saw the hand, and heard the man complain
of acute pain, and say he was stung by a worm, I called to mind the
circumstance related of Dr Clarke; and from the subsequent symptoms,
application, and cure, I could have little doubt that both were stung by the
same creature. I am no naturalist; but I have thought it right to relate a fact
that came within my own observation, the value of which I leave to be estimated
by others. I would only add, that neither Dr Clarke, nor any one who has had a
poultice applied for the purpose of extracting the worm, have said that they saw
the worm when it was extracted.
There can be no
doubt here that this classic fury worm scenario was actually elicited not by a
worm at all but rather by an insect, seemingly one of the countless tiny blood-sucking
ceratopogonids or biting midges belonging to the taxonomic order Diptera
(housing the true flies, gnats, and mosquitoes) that infest the marshy lands of
northern Scandinavia.

insect rearing (public domain)
Incidentally, one modern-day mention of Furia suggested a horse-fly as a possible identity. However, these particular insects have already been so familiar in their own right to farmers and other rural workers since the very earliest of times, due to their large, readily-visible, aggressive nature coupled with their adult females' only too well-known biting capability, that this seems exceedingly implausible.
Following on
from the pronouncements of such notable authorities as German physiologist Prof.
Johann F. Blumenbach and eminent Swedish worm specialist Prof. Karl A. Rudolphi
(widely credited as being 'the Father of Helminthology'), who had previously –
and publicly - professed serious doubt as to its reality, by the end of the
19th Century the fury worm had largely been dismissed by the scientific world
as non-existent, as fabulous as the unicorn, cyclops, and minotaur.
This was due in
no small way to the inescapable fact that despite its notoriety since
Linnaeus's near-fatal encounter, not a single example of his much-dreaded
vermiform assailant had ever been scientifically examined and verified. (It is
nowadays acknowledged that the alleged specimen brought to him by the peasant
had most likely been nothing more than an insect larva.) Indeed, even Linnaeus
himself had eventually come to doubt that the creature responsible for his
injury had been a worm, believing instead that the extreme severity of his affliction
had clouded his judgement when attempting to classify the culprit. Moreover,
despite generic claims appearing in several Furia documentations from
the late 1700s to the mid-1800s concerning how the worm had sometimes been
extracted from the flesh of its supposed victims, there never seemed to be any
first-hand accounts of the worm itself from witnesses present at such events.
Also by the late
1800s, increased medical knowledge had led to widespread recognition that
certain people (and individual animals) could exhibit hypersensitive responses
or allergic reactions to insect bites and stings, not to mention septic wounds
caused by bacteria or viruses, resulting in an array of highly alarming and
sometimes life-threatening symptoms corresponding accurately with those
described by Linnaeus and other supposed fury worm victims. Furthermore, they
can be incited even by insects as tiny and inconspicuous as biting midges of
the kind witnessed by Inglis (and which no doubt explained Linnaeus's attack
too – midges abound in marshy terrain). In stark contrast, not even the most
proficient medical practitioners had any concept of such phenomena back in
Linnaeus's time. Consequently, they were much more susceptible to believing in
the existence of a deadly worm fervently if falsely deemed real by local
peasants steeped in centuries of imaginative, unfounded folklore and groundless
superstition.
Interestingly,
some authorities during the 20th Century suggested that certain victims with
symptoms originally claimed to have been the work of the fury worm may actually
have been suffering from a version of anthrax, a deadly disease caused by the
bacterium Bacillus anthracis – as famously discovered by pioneering
German microbiologist Dr Robert Koch in 1875. Anthrax occurs in four versions –
inhalation, injection, intestinal, and cutaneous (skin), with the
last-mentioned one being the version proposed by supporters of an anthrax
explanation for fury worm symptoms. It occurs when endospores produced by the
bacterium enter a victim's skin via skin abrasions.

In reality,
however, this identity fails to provide a satisfactory solution to the fury
worm riddle. For whereas cutaneous anthrax does indeed produce an ulcer with a
black central dot recalling the black spot or speck that would appear shortly
after a supposed sting and penetration by a fury worm, it is usually painless,
in stark contrast to the excruciating pain suffered by victims of the alleged
worm. In addition, cutaneous anthrax is rarely fatal if treated, because the
infection is normally confined to the skin, whereas the effects of a supposed fury
worm sting and penetration used to spread swiftly through a victim's body and
cause severe, rapid swelling and inflammation – all of which is indicative of a
hyper-allergenic reaction to an insect sting or bite.
I did consider
the possibility that the culprit for the fury worm's nefarious crimes was
conceivably a tick or a mite. Infected ticks of the genus Ixodes are vectors
of Lyme disease (caused by Borrelia bacteria), but its most common initial
symptom is a red rash that is neither itchy nor painful (unlike the acute inflammation
attributed to Furia), and these small blood-sucking arachnids are
ectoparasitic; they do not burrow inside their hosts' flesh like Furia
did.

and female Ixodes ricinus, a vector of Lyme disease – this photograph
shows the small male tick copulating with the much larger female tick (public
domain)
Conversely, many
mites are microscopic (explaining why Furia was never seen?) and, again
like Furia, some certainly do burrow into the skin of their much larger
hosts. The familiar skin ailments scabies and mange are caused by such
creatures. In addition, dust mites can induce allergic diseases that include
eczema, which can be quite severe in hypersensitive victims.
Also worth
noting is that the larvae of trombiculid chigger mites, which feed upon humans
skin flakes and in so doing are responsible for the red and notoriously itchy
skin rash known as trombiculosis or chigger bite, make contact with their
victims in a manner that is reminiscent of descriptions given in various Furia
accounts already documented here - as shown via the following excerpt from
Wikipedia's trombiculosis entry:
Chiggers are commonly found on the tip of blades of
grasses to catch a host, so keeping grass short, and removing brush and wood
debris where potential mite hosts may live, can limit their impact on an area.
Sunlight that penetrates the grass will make the lawn drier and make it less
favorable for chigger survival.
Chiggers seem to affect warm covered areas of the
body more than drier areas. Thus, the bites are often clustered behind the
knees, or beneath tight undergarments such as socks, underwear, or brassieres.
Areas higher in the body (chest, back, waist-band, and under-arms) are affected
more easily in small children than in adults, since children are shorter and
are more likely than adults to come in contact with low-lying vegetation and
dry grass where chiggers thrive.

(public domain)
Ordinarily,
therefore, I would suggest that perhaps a form of parasitic mite may have been
responsible for at least some cases attributed to the fury worm. However, I am
not aware of any that engender such uniquely devastating effects upon their
hosts as those induced by Furia, especially as the latter reputedly
achieved them via the action of just a single specimen, not even by several
simultaneously. So unless Furia was a species of inordinately hostile parasitic
mite that died out before its correct taxonomic identity could be scientifically
revealed, which seems highly unlikely, a mite is surely a very remote
explanation for it.
Equally, a single tiny worm blown by a wind current onto the skin of its human victim, then stinging and instantly burrowing deep within the victim's skin where it rapidly induces agonising pain and quite often death does not recall the lifestyle and modus operandi of any of the many different taxa of parasitic worm (which include tapeworms, thorny-headed worms, various flukes and nematodes, larval horsehair worms, tongue worms), despite their considerable variety of form and activity.
In any case, the
extreme rapidity of the virulent and sometimes fatal activity claimed for Furia
(Linnaeus himself alleged that it could kill a human in as little as 15 minutes)
clashes with a fundamental tenet of parasite evolution and success, which is to
keep its host alive and healthy for as long as possible while the parasite is
benefiting from their association. After all, if the host dies prematurely, the
parasite loses its nutrient supply, its home, and also in multi-host species
the opportunity for the next stage in its life cycle to transfer to its next
host. So how could Furia possibly benefit by killing its host so quickly
– and indeed, what benefit did it gain by burrowing beneath its victim's flesh
anyway? Remarkably, however, this basic question seems never even to have been
posed in any of the many Furia documentations that I have read, let
alone answered. To my mind, therefore, the fury worm as a parasite of any kind
(let alone an actual worm) exhibiting the extreme behaviour ascribed to it
makes no zoological sense at all.
As for the herds
of reindeer supposedly killed in Lapland by Furia, conversely, modern
science has revealed that a worm was indeed responsible for their deaths (such fatalities
still occur today), but it wasn't the fury worm. Instead, these deer were and still
are afflicted by neurocysticercosis – an infectious disease caused by the presence
in their brains of larvae from the pork tapeworm Taenia solium, which
can also affect humans. Here, the parasite does indeed kill its host, but not
before the parasite's larvae have had time to mature, so that they are ready to
enter their new host when it eats the meat of their present one.

Quite frankly, the
most reasonable, sensible explanation for the fury worm is that it was never
anything more than simply a convenient composite scapegoat, a non-existent 'bogeyman
worm' of strictly folkloric origin that rural Scandinavians would habitually
blame for any unexpected bite, sting, abscess, or other skin-sited ailment whose
origin they could not readily determine, whether that be a particular type of insect,
or arachnid, or tapeworm, or bacterium, etc. This would explain the marked inconsistency
of claims regarding the fury worm's supposed morphology, its sting's symptoms, and
the speed of their lethality, because in reality they had not originated from a
single inimical species at all, but instead from a whole range of them, yet wrongly
combined with each other in rural tradition and superstition to yield an
entirely fictitious composite, the fury worm.
In Pallas's
lengthy account of the fury worm presented earlier here, he stated that it
compared closely with a hair worm. Also known as horsehair worms or
nematomorphs and of worldwide distribution, these come in many different
species, and sizes - ranging from around 20 in to as lengthy as 6 ft, but no
more than 0.12 in across (and sometimes as little as 0.04 in). Inhabiting
ponds, streams, puddles, and even horse troughs (there are also some marine
species, as well as some semi-terrestrial ones), the adults are free-living,
whereas the larvae parasitise small arthropods. The most familiar horsehair
worms belong to the genus Gordius, and in the Vermes section of his Systema
Naturae (10th edition), Linnaeus placed Furia directly below his naming
and description of Gordius, thus emphasising their supposed similarity
as claimed by local testimony.
Providing a very
relevant precedent and caveat here, however, is that these same rural
Scandinavian peasants who believed in the fury worm and its dread stinging/flesh-burrowing
activity also seriously believed that Gordius was venomous too, yet in
reality it is entirely harmless. Equally, just as they were convinced that Furia
dropped down upon its victims directly from the sky or was carried to them on
the wind, they asserted that Gordius worms were actually hairs that had
originally been shed from the manes of horses but which then had spontaneously
come alive. In other words, there are good reasons indeed to treat their beliefs
and claims regarding Furia with grave suspicion.
The
common horsehair worm Gordius aquaticus (public domain)
The widespread
fallacy in rural Sweden that Gordius was venomous was exposed
scientifically as far back as the early 1820s by Prof. Anders Retzius, a
Swedish anatomist with a particular interest in Furia, as described in
1827 by Arthur de Capell Brooke in his earlier-cited Edinburgh New
Philosophical Journal paper:
…the Academy of Sciences at Stockholm, with an
anxious desire to discover the truth, has promised, on several occasions, a
considerable reward to whoever should lay before it a specimen of the animal
in question [Furia infernalis]; none, however, have been presented to
their notice, but what, upon examination, have been proved to be fictitious.
With this information I have been favoured by Mr Retzius of Stockholm, son of
the late distinguished naturalist [Prof. Anders Jahan Retzius]. This gentleman
has informed me, that he has himself made frequent searches to no purpose on
the borders of the Mäler, and other Swedish lakes, in the hopes of discovering
this formidable being; and he adds, that, with regard to the Gordius
aquaticus, or hair-worm, the bite of which has been supposed to be dangerous,
his own personal experience has convinced him, that it is perfectly harmless;
for, during the space of ten years, when he resided at Carlberg, as physician
of the military academy, he was daily accustomed to see the young cadets of the
establishment bathing in places where these animals were to be seen in
thousands, and yet no accident was ever the result.
Who knows, perhaps
the Scandinavian peasants' mistaken yet longstanding supposition that horsehair
worms were venomous may also have played an active role in their nurturing an even more
imaginative belief, in an even more deadly but this time entirely fictitious
version – which an erroneously-afflicted Linnaeus duly dubbed the fury worm.
And thus was a fable made fact, until medical science finally swept it into the
dustbin of discredited disease-mongers, alongside the tooth worm, the sweat
louse, and other comparably noxious yet equally non-existent pathological
ne'er-do-wells.

Remorse of Orestes', after killing Clytemnestra, surrounded and harassed by the
Furies, painted by William-Adolphe Bouguereau, 1862 (public domain)
