Leibniz's Unicorn
Otto von Geuricke was not a fool. During his lifetime he was
a philosopher, diplomat, Mayor of Magdeburg for thirty-one years, and a
respected scientist and inventor. It was for his work the last two capacities
that he is probably best remembered. Geuricke invented the vacuum pump and
performed public experiments with it that made him a welcome member of the
European scientific elite. With that resume, it might surprise modern readers
to find him calmly describing a unicorn in his main scientific work before
moving on to more important topics.
His description is short. In its entirety, it reads:
It happened in the year 1663 in Quidlinberg, that on the Mountain the common people call Zeunickenberg, where lime is mined, inside the rock a unicorn skeleton was found. The rear portion of the body, as is common in a beast, lay back, head up, but, extending lengthwise from the brow was a horn, the thickness of a human leg, and so in proportion to the length of almost five cubits. Primarily through ignorance, the skeleton of the animal was broken and extracted in pieces. Together with the head with the horn and some ribs, spine, and bones, were given to the Reverend head abbess of the place.
The passage gives no indication whether Geuricke ever saw
the bones himself, though he had plenty of opportunity to do so. Quedlinberg is
less than thirty miles from Magdeburg and much of Guricke's technical
innovation was aimed at making mining safer and more efficient, so he must have
visited the mining regions. However, there is nothing in his writings to
indicate that he ever looked further into the story. Guericke was an important
enough scientist that his books were read and discussed by the scientific elite
all over Europe. The Quedlinberg unicorn was mentioned a few times over the
next few years and would have been forgotten except for the fact that the great
Gottfried Wilhelm von Leibnitz repeated the story and produced a drawing of the
skeleton.
In the years 1691-3, Leibniz was working on a geological
history of that part of Germany as a Michener-style prologue to his history of
the house of Brunswick and their lands. A large part of his work dealt with
fossils. The presence of entire strata of salt water seashells on high ground
disturbed and intrigued Seventeenth Century natural philosophers. Leibniz
catalogued and analyzed the shells in his region. Following that, he looked at
some of the other difficult organic remains buried in the mountains. Buried
ivory was right at the top of the list.
Buried ivory had several names, one of the most common, at
least to people who spoke Latin, was "unicornu fossili"--fossil
unicorn. At that time, the word "fossil" was evolving from its
original meaning of "something from the ground" into its modern
meaning of "petrified organic matter." Another transformation
happening at the time had to do with the word "unicorn." The belief
in, and giving a damn about, the animal unicorn peaked during the Renaissance.
Unicorn horn was a protection against poisons and a universal antidote should
you be poisoned. No one was anyone unless someone wanted them dead. Unicorn
horn’s medical powers were not limited to poison. It was also useful in
treating “Scurvy, Old Ulcers, Dropsie, Running Gout, consumptions,
Distillations, Coughs, Palpitation of the Heart, Fainting Fits, Convulsions,
Kings Evil, Rickets in Children, Melancholly or Sadness, The Green Sickness,
Obstructions, and all Distempers proceeding from a Cold Cause." Fragments
of unicorn horn were worth more than their weight in gold. A complete horn was
worth more than a medium sized town.
Its very success doomed the unicorn. Nothing about the
unicorn could stand up to extended scrutiny. From one side, physicians
questioned the idea of a universal antidote. Nature was composed of pairs of
opposites, hot vs. cold, wet vs. dry. How could the same medicine counteract a
wet poison and also a dry poison? Naturalists hunted the world for the unicorn
animal and found hints and claims, but no actual unicorns. By the late
Seventeenth Century, faith in the existence of an actual unicorn animal was
fading fast. Several different writers demonstrated that the straight spiral
horn, so beloved by medieval artists, actually came from a sea animal caught in
the icy waters surrounding Greenland. Other pieces of unicorn horn were shown
to be walrus tusks, elephant ivory, or cheaper substances such teeth and bones
of farm animals. The last great hope for unicorn believers was fossil ivory.
Finding ivory in the ground was pretty amazing. Guericke adhered to the belief
that it actually grew there. Not that it was a plant, but that it was real
ivory created by some generative power within the earth. If fossil ivory had
such had such a wonderful origin, crediting it with diverse medical powers was
no great stretch of the mind.
When Leibniz repeated Guericke’s story, he made it clear
that, in his opinion, unicornu fossili was the remains of real animals. What’s
more he was sure it was the remains of known animals. He allowed that in rare
cases it might ivory of elephants washed into the North by the Biblical deluge,
but he confident that in most cases it was the remains of walruses and narwhals
that had lived there when the shoreline of the North Sea was far to the south
of its present location. Still, Guericke was a man of impeccable reputation and
the story was an interesting one. Following his recounting of the story as told
by Guericke, Leibniz added: “The same has been reported to me. An illustration
was added which it is not inappropriate to submit here.”

Leibniz never finished his history. In fact he never went
any further than writing the geological preface. Both the text and the drawing
sat in his papers until 1749, over thirty years after his death. In that year,
Ludwig Scheidt, the librarian of the house of Brunswick, edited the treatise into
chapters and had the drawings Leibniz had collected engraved onto printing
plates. The result was published in Latin and German as Protogaea, or A
Dissertation on the Original Aspect of the Earth and the Vestiges of Its Very
Ancient History in the Monuments of Nature. The unicorn appeared on the same
page as the tooth of a mammoth (referred to as that of a “marine animal”) and
carried the caption “Image of a skeleton excavated near Quedlinberg.”
The image and description have gone on to become quite
famous. While the bizarreness of the image has a lot to do with that fame, the
image has a valid claim to being a significant milestone in paleontology. Science
writers often call it the first paleontological reconstruction. To call it
that, requires a few qualifiers. Every time a medieval parish priest laid out
some large bones and imagined his village had discovered a giant, he was making
a paleontological reconstruction of sorts. What made the Quedlinberg unicorn
special was that published and directed at a scientifically literate audience.
But that’s not the whole story of the Quedlinberg unicorn. Over
the years, both Guericke and Leibniz have been credited as the artists. Guericke
is an unlikely source. His book was well illustrated and, if he found the story
interesting enough to add to his book, it seems that he would have used the
illustration if he had had it in his possession. Leibniz is definitely not the
artist. He explicitly says he received the drawing from an unnamed person whose
account backed up Guericke’s. As I mentioned above, Leibniz and Guericke was
not the only writers to draw attention to the story. The most interesting publication
happened in 1704, while Leibniz was still alive. In a catalog and commentary on
the great collections of Europe, Michael Bernard Valentini published a version
of the reconstruction. Valentini wrote that the illustration was based on a sketch
by Johann Mäyern, a counselor at Quedlinberg. Valentini’s illustration is of
much lower quality than Leibniz’s. Was Mäyern Leibniz’s other source or was
there a third drawing that they both copied? Unless Mäyern’s original drawing
shows up, we will probably never know.

In the early Twentieth Century, the Austrian paleontologist Othenio
Abel took an interest in the Quedlinberg unicorn. Abel had already casually mentioned
the story in several of his books before he decided to get serious and try to
figure out what the skeleton really was. They actual bones had long since
disappeared and no other drawings or descriptions had ever been made of them.
The best evidence he had to work with was Leibniz’s drawing. Abel immediately recognized
that this not a single skeleton that had been reassembled in a whimsical
manner. The bones came from at least two individuals and two different species.
The skull is that of a woolly rhinoceros. The teeth, scapulae, and vertebrae
are from a mammoth. Most of the spine has been reassembled backwards and upside
down. What at first glance look like ribs are really dorsal spines that are
part of the individual vertebrae. The loop at the bottom is the first cervical
vertebra. And the horn; what is the horn? It’s too long to be a walrus tusk and
too wide to be a narwhal tooth, Leibniz’s preferred explanation for fossil
ivory. Rhinoceros horns are not made of bone or ivory. They’re made of keratin,
the material as hair and finger nails. It’s unlikely that the learned burgers
of Quedlinberg would have mistaken that for a unicorn horn. That leaves a
mammoth tusk, which easily meets the length and width requirements. It takes a
little more speculation to explain its being straight and not curved. There are
two possibilities here. One is that the tusk was badly enough broken up that
the people who reassembled it had the freedom to make it any shape they wanted.
The other possibility is that it came from a different kind of extinct
elephant, such as the palaeoloxodon, a species that went extinct about 15,000
years before the mammoth and that had much straighter tusks.
There is a cave near Quedinberg called the Einhornhöhle or
Unicorn Cave. Even before the gypsum miners on Zeunickenberg found their strange
skeleton, the locals had been bringing bones out the local caves and selling
them to apothecaries as “genuine” unicorn horn. This explains why the Quedlinberg
burgers had unicorn on their minds as they tried to make sense out of a pile of
broken bones. No doubt, someone had the idea of getting in on the unicorn
trade. But the price of unicorn horn was crashing in the late Seventeenth
Century and any plans they might have had never came to fruition. Leibniz
visited the area in 1686 and crawled through several caves, but didn’t find any
unicorns, which explains his noncommittal tone when he repeated Guericke’s
story six years later.
That’s not the end of the story. In the Nineteenth Century,
paleontologists explored the caves in the Harz Mountains and identified the
bones of dozens of species of Pleistocene mammals. In the Twentieth century,
the local governments realized the tourist potential of the caves and dug
comfortable entrance tunnels into them. There are several small museums in the
region proudly showing off the bones. There are several full sized models of
the unicorn on display. One of them guards the entrance to the Einhornhöhle. Tourist
shops sell paperweights and t-shirts adorned with Leibniz’s drawing. The Quedlinberg
unicorn lives on.

Another Unicorn and How I Came to Write the Book
The mammoth book grew out of an idea for a single blog post.
I love forbidden history and catastrophist books, such as those about Atlantis
and Velikovskyism. It doesn't take long when reading these to notice that the
all depend on a limited bits of evidence to prove vastly different theories.
Among the favorites are the Great Pyramid and frozen mammoths. Out of
curiosity, I decided one day to look at the history of mammoth discoveries to
figure out what was known at the times different Atlantis writers wrote since
it wouldn't be fair to criticize them for not knowing something that hadn't
been discovered yet. As the blog post got out of hand, it occurred to me that
this long essay could perhaps become a small book. I had four books on mammoths
at the time. I figured those four and a couple of books on paleontology would
be all I needed. I wasn't that serious about it; it was just an idea.
Just as the blog post had gotten out of hand, the essay
began to get out of hand. In each of the books I found discoveries and ideas
that I wanted to know more about. I began mining the bibliographies of those
four books. I found minor mistakes in them and differences of interpretation
that bothered me. I mined the bibliographies a little further. One day I
shelled out almost eighty bucks for a Nineteenth Century book and realized that
I was starting to get serious. Atlantis had vanished from the idea and it was
all about mammoths. About five years ago, I realized I really was writing a
book. When I began spending more and more time tracking down primary sources
for various bits of data and context, I realized I was also writing the
dissertation that had never happened when I dropped out of grad school.
And then I entered my translation phase. When I first got
serious, machine translation was still pretty iffy, but it's improved
dramatically over the last few years. Whereas I once groaned at the thought of
doing a few paragraphs of a modern language, I now think nothing of ten pages
of Latin. Naturally, this has meant digging into even more original sources.
Sometimes this means even when an English translation is available, I'll go to
the original to make sure I'm not missing anything. This is how I made my
latest discovery.
Gottfried Wilhelm von Leibniz is probably best known for
inventing calculus. But he was much more than a mathematician; he wrote about
philosophy, medicine, physics, linguistics, history, and politics; he tinkered
with lamps, clocks, pumps, and invented an adding machine; I've heard he mixed
the best Bloody Mary in all Germany and danced a mean Polka; he also took a
shot at geology and paleontology. In 1690, his patron, the Elector of Hanover,
commissioned him to write a history of the province of Brunswick. Leibniz chose
to start with the geological prehistory of the land as a background for the
human and dynastic history. He didn't get any further in his history. Thirty
years after his death, this essay was published under the title Protagea.
Leibniz's contribution to mammoth history appears in
Protagea. Leibniz recounted a story told originally by Otto Gericke, the
inventor of the vacuum pump, of the discovery of some unicorn bones near
Quedlinberg in the Harz Mountains. He also published a reconstruction of the
unicorn skeleton that he received from an unnamed second source. The teeth are
probably mammoth's teeth and the skull is probably from a woolly rhino, but the
horn, which was reassembled from pieces, is clearly a mammoth's tusk that was
straightened by the reconstructors. The unicorn drawing is a standard part of
mammoth lore.
I had read that Leibniz's text description was lifted from
Gericke's almost word for word. The "almost" got my attention.
Yesterday, I decided to compare the two to see if Leibniz had left out or
changed anything (he hadn't). Gericke's description is in his book on the
vacuum pump. Don't ask me why; that's just how they rolled in the Seventeenth
Century. Naturally, the book is in Latin, but so is the first edition of Protagea,
making a direct comparison possible. While hunting for the passage in Protagea
I came across a familiar word "mammotekoos"--mammoth bones. This word
appears two pages before the unicorn story but it has never been mentioned in any
previous book on mammoths.
I know of only one other mammoth writer who has mentioned Leibniz’s
mammotekoos, but not in the context of mammoths. Claudine Cohen, a French
historian of science, published The Fate of the Mammoth in 2002. About a third
of her book covers the same material that I'm covering. She uses Gericke and
Leibniz unicorn as the launching point for one of her chapters, but she missed
the mammotekoos. Ironically, in 2010 she edited and published an English
translation of Protogaea with commentary. In the chapter where mammotekoos
appears, she has a small footnote on the word. If she had written the Protagea
commentary before her mammoth book she would have been able comment on the
relevance of the word in the context of mammoths and all I would be able to do
would been to agree or disagree with what she said. Ha-ha, now I get to go
first.
Alright, what is there to say about Leibniz and the word
mammotekoos? The context of his use is a passage about bones found in the caves
of the Harz Mountains. These caves are a treasure-trove for paleontologists.
Many of the caves contain bones of Pleistocene megafauna such as cave bears,
woolly rhinoceros, and mammoths. Leibniz took the, then common, position that
these bones had been washed there by the Biblical Deluge. He also held to a
less common idea that the North Sea had once extended as far south as the Harz Mountains.
This idea was necessary to explain seashells in lower strata. In Protagea, he
suggests that the latter could also be used as an explanation for unicorn horn
and other fossil ivory, in that they were probably really walrus tusks.
Here is the quote. It's a mix of Cohen's translation and a
little grammatical editing by me.
So there was nothing to stop foreign animals to be brought to us by the force of the waves, although I find elephants less believable because they could belong to the Rosmarus [walrus] I mentioned above. The teeth reportedly dug up in Mexico are perhaps of the same kind since no elephants are found in America today. I would say the same thing of those heavy teeth, like the bones of whales, called Mammotekoos by the Moscovites and attributed to the elephant, as Witsen reports. Yet, I will not obstinately deny that true elephant’s bones are sometimes found. Certainly, we have seen teeth and a part of the tibia and other bones taken from the Scharzfeld cave. No one could say whether they came from an elephant or similar animal; whether in the past they might have been more widely scattered throughout the world than today; whether their nature or the nature of the world had changed; or whether they had been moved from a far country by the rushing waters.
This passage is important in that Leibniz is the first
writer to bring together European fossil elephants, giant bones from the New World,
the majority of which would have been mastodons, and the Siberian mammoth and
recognize them as probably related species. Of course, his solution that they
were all walruses is wrong, but not unreasonable for the times. The Witsen Leibniz
mentions as his source for mammotekoos Nicholaes Witsen. Witsen knew ivory. As
a Dutch merchant he had been to the East Indies and to Africa where he had
purchased the tusks of both Asian and African elephants. He knew about Siberian
mammoth ivory because he had been to the markets of Moscow and interrogated the
ivory merchants there. In his book on Russia and Siberia, Noord en Oost
Tartarye, he recognized that mammoth ivory looked like real elephant ivory. He
wouldn't go so far as to say it really came from elephants only that, if it
did, it could only be because dead elephants were washed there by the Flood. Witsen
did not mention walruses, but he did say that most mammoth ivory came from the
Arctic coast. By the time of Witsen and Leibniz, Europeans had known about the
Russian ivory trade for over 150 years. Leibniz, who had not seen a mammoth
tusk, appears to have assumed that mammoth was no more than another name for
walrus. He was not the last to make that assumption. As late as thirty years
later, after whole tusks and other bones of mammoths had been carried to
Western Europe for examination, Theodore Hase could still publish a fifty-eight
page tract arguing that mammoth was another word for walrus.
This passage in Protagea offers something for Leibniz
scholars, though I'm not sure if it rises above the level of curious trivia or
not. Leibniz devotes quite a few pages to fossils so I'm sure everything I said
above about Leibniz’s attitudes regarding fossils has been said in the past;
only my emphasis on elephants and mammoths is original. The word mammotekoos is
a point that can be used to date that part of the Protagea. It is known that Leibniz
worked on his history through 1691-3. Witsen's Noord en Oost Tartarye was
published in 1692, placing Leibniz’s composition of that passage in the second
half of the period. If Leibniz had published Protagea as a separate volume as
soon as he finished it, his would have been only the third time any form of the
word mammoth had appeared in print.
This is why my book is taking so long. Not only have I spent
almost three years translating and retranslating primary sources and lost most
of another year due to personal crises, I also have these obsessive moments
when I'll spend two days analyzing a half of a paragraph. On the other hand,
it's this kind of obsessiveness that leads me to make new discoveries. Up above
where I said Protagea could have been the third time any form of mammoth had
appeared in print, the Oxford English Dictionary would tell you it would have
been the second, with Witsen as the first. I know of an earlier one. As far as
I know, I'll be the first person to draw attention to it. That alone should be a
good enough reason for you to buy several copies of the book when it comes out.
And now, since the original purpose of looking at Leibniz
was to comment on the Quedlinburg unicorn, I should get to work on that. I'll
post a partial rough draft with the amazing drawing later today or tomorrow.
