Damned Souls and Fiery Oceans - Early Views Of Earth`s Core
"We know more about the stars high above our heads, than about earth just below our feet."
Leonardo da Vinci
Leonardo da Vinci
There is some truth in da Vinci´s words, as for a long time the interior of earth was a mysterious place, supposedly the reign of demons and place of eternal damnation. Italian poet Dante Alighieri (1265-1321) imagined a core of ice, an allegoric image, far away from the sun and divine light where the damned souls are entrapped in eternal ice.
German Jesuit Athanasius Kircher (1602–1680) imagined earth´s section in his "Mundus Subterraneus" (1664-1665) as crossed by veins of water and fire. The water would feed springs and rivers, the fire the volcanic mountains – but apart practical observations Kircher´s worldview was influenced also by religious-philosophical considerations, the two opposite elements water and fire united in a perfect creation.
Leonardo da Vinci´s (1452-1519) approach was more rational, even if inspired by the idea that earth worked a bit like a human body, just blood replaced by water. Water, so da Vinci, eroded, transported and deposited sediments, connecting mountains with the sea. He imagined earth filled by an immense underground ocean, sections of the superficial crust sinking into it would explain the formation of mountains.

James Hutton (1726-1797) recognized the importance of magmatic rocks on earth. To explain the large quantities of volcanic rocks on earth´s surface and the energy needed to melt rocks, Plutonists proposed a molten interior, even if it is was not clear if molten rocks form most of earth or were to be found in only large magmatic chambers, distributed in the upper layers of earth.

French science-fiction author Jules Gabriel Verne (1828 - 1905) based his novel "A Journey to the Center of the Earth" (1864) on the science of his time. In his novel Verne uses the hollow conduit of the Icelandic volcano Snæfellsjökull to venture inside earth, an idea supported by the geologic models of volcanoes proposed at the time - a single or a series of magma chamber(s) with conduits connecting them to the surface. Geologists assumed that during an eruption the magma reservoir becomes empty and large voids and caverns were left behind.
Fig.4. Geological section, published in the book "Einführung in die Erdbeben- und Vulkankunde Süditaliens" (1914), shows the anatomy of a stratovolcano, with a main conduit, various lateral dikes and a large sill connected to the magma reservoir.
The Spanish adaptation of Verne´s novel "The Fabulous Journey to the Center of the Earth"/ Where Time Began" (1976) summarizes best the problems geologists faced all this time:
"-Gentleman, the truth is that all our theories are just that, theories. None of us has the least idea of how the earth was really formed. Because the distance between the earths crust and its core is over 6.500 kilometres, and no men has ever descended to a depth of more than 3 miles. So it's obvious, we will never have a glimmer of true knowledge, until we are able to reach a depth of at least a 100 leagues.
- What's your opinion Professor Lindenbrook?
- Well gentlemen, at one point at least I agree with Professor Christophe, the materials of the geologists are not charts, chalk and chatter, but the earth itself. We should never know the truth, until we are able to make that journey, and see for ourselves."

Of Dragons and Geology
Johann Jakob Scheuchzer (1672-1733)
was a Swiss physician, but also quite interested in travels and natural
sciences. He published his observations on the culture and natural

What's in a name? - Mineralogy
It may seems strange, but Romans didn´t know minerals, despite crystals of quartz were well known and various famous mines of gold, silver and lead date back to these times, but so they didn´t know "mines". Roman naturalist used the term "metallum", derived from the Greek language, to describe both real metals as non-metallic minerals like salt, sulphur or gemstones. “Ad metallum damnare” was therefore the punishment to work in mines to extract rocks and metals. Only in medieval times the term “metalliarum” or “metallum”/“metullum” refers in specific to real metallic elements, like gold and iron, as mines where such ores are found.
The modern term and use of the word "mine" derives probably from the celtic word “meini”, may referring to both the ore as the mine, as still in medieval Latin the word “minera/minora” can be used to describe the metal as the galleries where it´s found. For sure the word “minae” referring to mining activities, can be found in documents dating back to 1143.
From medieval mines the word will later give to "the minerals" their name and finally to the "study of minerals" - mineralogy.

How Charles Darwin Classified His Minerals And Rocks
In an autobiographic note Charles Darwin remembers a childhood wish:
“It was soon after I began collecting stones, i.e., when 9 or 10, that I distinctly recollect the desire I had of being able to know something about every pebble in front of the hall door–it was my earliest and only geological aspiration at that time.“
Also during later school years Darwin remains interested in chemistry and minerals, however he laments that “I continued to collecting minerals with much zeal, but quite unscientifically – all that I cared was a new named mineral, and I hardly attempted to classify them.” As a medicine student at Edinburgh University (1825-1827) Darwin frequented various courses on natural sciences, also lectured by mineralogist Professor Robert Jameson, however he considered Jameson´s lectures as „incredibly dull“. Nevertheless Darwin seems to have used frequently Jameson´s „Manual of Mineralogy“ for his private studies, as it is one of the most heavily annotated books in his library. Jameson´s manual uses physical properies, like color and especially the degree of hardness, introduced by German mineralogist Carl Friedrich Christian Mohs in 1822-1824, for mineral identification. Darwin adopts this “visual characterization” approach, so he often describes rocks based on the well visible physical properties, referring to mineral texture or colors, using terms like “porphyry”, for rocks with large, well visible, crystals, "greystone" or “greenstone”, a general name for greenish-dark magmatic rocks (today classified as dolerite-basalt).
In summer of 1831 Darwin joined a field trip of professor Adam Sedgwick, geologizing in Wales. Darwin was interested in acquiring the basics of geological field work, structural geology and rock classification. Twenty pages of notes made by Darwin during this tour are still today preserved – in his autobiography he will later remember: “This tour was of decided use in teaching me a little how to make out the geology of a country...”
When Darwin returned to Shrewsbury, August 29th, a letter from Captain Robert FitzRoy was offering him a position as gentlemen companion on board of the brig Beagle, ready to set sail from Plymouth in December 1831.

Darwin used the remaining time to exercise mineral identification with the blowpipe (heating a mineral you then observe the chemical redactions and modifications of the specimen to identify it or its composing elements) and muriatic (hydrochloric) acid, useful to distinguish between carbonatic and siliceous rocks
On board of the Beagle Darwin could rely on a complete library for mineral identification, like "A selection of the Geological Memoirs" (1824), including a mineral chart by French geologist A. Brongniart. These manuals use properties like color, hardness, form, but also taste and odour for mineral identification. Darwin got for himself a goniometer, to measure angles of crystal-faces, a not easy to use tool in the field but Darwin proudly remarks "Hornblende determined by myself with goniometer".
Especially interesting are classification charts based on the color of a specimen. "Werner's nomenclature of colors”, published in 1821 by Patrick Syme (1774-1845), is a book displaying a chart and description of various colors to be compared with the colors of minerals, animals and plants. Darwin used this book to describe snakes, rocks and even the "beryl blue" glaciers.

Fig.1. Page from "Werner's nomenclature of colors”, the book was brought on board of the Beagle by Darwin himself.
It is curious to note that Darwin not only used a mineral classification scheme based on the work of German mineralogist Mohs. He adopted also the geological terms used mostly by German geologists, like Alexander von Humboldt, to describe the rocks observed in the field. Darwin will become especially interested in volcanic rocks.
Darwin´s final advice published in 1839 for collecting rocks has value still today (even if Darwin himself admitted he didn´t follow it always):
"Put a number on every specimen, and every fragment of a specimen; and during the very same minute let it be entered in the catalogue, so that if hereafter its locality be doubted, the collector may say in good truth, “Every specimen of mine was ticketed on the spot." Any thing which is folded up in paper, or put into a separate box, ought to have a number on the outside (with the exception perhaps of geological specimens), but more especially a duplicate number on the inside attached to the specimen itself."
Fig.2. Page with rock-classification from Jameson 1821 (influenced strongly by the work of German geologists), Darwin will himself adopt "German" terms like "Amygdaloid" to describe basaltic lava flows observed on the volcanic islands visited during the voyage of the Beagle.

Ancient Stories Provided An Early Warning About Potential Seattle Earthquakes
Oral tradition played – and still plays – an important role in many
societies. The subjects of these stories range from fantastic fairy
tales to myths, tales based on real persons, places or historic events.
But interestingly enough, these stories may also represent attempts to
record and transfer knowledge of past geological catastrophes as a
warning from generation to generation. Read On...
How Volcanic Eruptions Inspired Artists
As diplomat in France, from 1776-1785, Benjamin Franklin noted in 1783 a strange, grey-bluish mist covering the sky above Europe. Franklin speculated that the cloud was some sort of volcanic dust, may transported from the wind from the Katla, famous Icelandic volcano, to the European mainland. In fact in June 1783 the Laki on Iceland had erupted, one of the largest volcanic eruptions in historic times with worldwide effects on earth´s atmosphere, climate and history.
But volcanic dust also influenced art and poetry.
A surprisingly colourful sunset inspired Norwegian artist Edvard Munch (1863-1944) to his famous painting “The Scream”. A distorted figure seems to be petrified screaming in pain, the red background reinforces the despair and agony. Munch himself noted:
"I was walking along the road with two friends - then the Sun set - all at once the sky became blood red - and I felt overcome with melancholy. I stood still and leaned against the railing, dead tired - clouds like blood and tongues of fire hung above the blue-black fjord and the city. My friends went on, and I stood alone, trembling with anxiety. I felt a great, unending scream piercing through nature."
Exceptional sunsets were observed above Oslo and in many other cities worldwide in the years 1885-92. The New York Times reports on November 28, 1883:
"Soon after 5 o’clock the western horizon suddenly flamed into a brilliant scarlet, which crimsoned sky and clouds. People in
the streets were startled at the unwonted sight and gathered in little groups on all the corners to gaze into the west. Many thought that a great fire was in progress
....People were standing on their steps and gazing from their windows as well as from the streets to wonder at the unusual sight. The clouds gradually deepened to a bloody red hue, and a sanguinary flush was on the sea…"

....People were standing on their steps and gazing from their windows as well as from the streets to wonder at the unusual sight. The clouds gradually deepened to a bloody red hue, and a sanguinary flush was on the sea…"
The red-glowing sunsets were caused by volcanic ash, dispersed in the higher atmospheric layers the fine particles scattered the sunlight especially effective during sunset.
August 1883 the volcanic island of Krakatoa in Indonesia had annihilated itself in a gigantic eruption. Ash, volcanic dust and gases were send in the higher atmospheric layers, high above clouds and rain the particles would stay for years there, inspiring artists and poets, like English poet Alfred, Lord Tennyson (1809-1892):
"Had the fierce ashes of some fiery peak
Been hurl’d so high they ranged about the globe?
For day by day, thro’ many a blood-red eve...
The wrathful sunset glared..."
Munch however was not the first painter to be inspired by the range of sky-colors caused by a volcanic eruption. Famous English landscape painter William S. Turner (1775-1851) was so impressed by the sunsets in the years 1815-16 that he produced an entire series of paintings, showing the changes observed in the sky for almost one year (Turner will also go on painting more volcano-related paintings).
In April 1815 the Tambora, also on Indonesia, had erupted, the largest volcanic eruptions in modern times. Also here volcanic particles and dust were injected in the stable stratosphere, scattering for years to come the sunlight and painting the sky in wonderful reddish, orange, bluish-violett colors, an inspiring and haunting view.

“The sun fades away, the land sinks into the sea,the bright stars disappear from the sky,
as smoke and fire destroy the world,
and the flames reach the sky.”

The true treasure of the North
GOLD! GOLD! GOLD! found in the Klondike river in the Yukon territory, Alaska. The news spread like wildfire, fueling the last great gold-rush of the United States in 1896-99.
Fig.1." The Prisoner of White Agony Creek" (2008).
Also French businessman Loicq de Lobel decided in 1898 to try his luck in the new world. Even if not directly interested in searching for gold, he hoped to make a living by selling equipment to the prospectors. So the family de Lobel, his wife and four children, following the famous Chilkoot Trail ventured into the northern wilderness, first by feet and later by boat. To distract herself from the perils of the voyage, de Loicq´s wife, which name is not recorded, botanized along the way. She collected for the very first time specimens of the endemic lady's-slipper orchid, Astralagus, bearberry, Epilobium, arnica and a blue-flowering bellflower.
“… everywhere there were nice flowers, at our arrival at Glenora we found lots of flowering plants...”
The de Lobel family lived for a time in the Yukon territory, then moved to the Aleuten Islands, to finally return to France. The Klondike Gold Rush ended as suddenly as it began, only few found great riches and fortune. However the collected plants by the de Lobel became known as “Klondike River Herbarium” and represents still today a unique botanic treasure.

April 18, 1906: San Francisco´s Wicked Ground
“O, promised land
O, wicked ground
Build a dream
Tear it down
O, promised landO, wicked ground
Build a dream
Tear it down
What a wicked ground
Build a dream
Watch it all fall down”
“San Andreas Fault”
Sailors on board of the “Wellington“, just entering the bay of San Francisco, noted something unusual in the early morning hours of April 18, 1906. The captain reported later that the ship “shivered and shook like a springless wagon on a corduroy road” even if the sea was as “smooth as glass.“
Clarence Judson was swimming near Ocean Beach when he suddenly was pulled by a strong current into the sea. He made it back to the shacking shores.
“I tried to run to where I left my shoes, hat and bathrobe ... but I guess I must have described all kinds of figures in the sand.“
“I tried to run to where I left my shoes, hat and bathrobe ... but I guess I must have described all kinds of figures in the sand.“
In Washington Street, police sergeant Jesse Cook observed a terrifying spectacle:
“The whole street ... It was as if the waves of the ocean were coming towards me, ...[]... Davis Street split right open in front of me, []… A gaping trench. . . about six feet deep and half full of water. Suddenly ...[]... the walls of the building began to shake. Before I could get into the shelter of the doorway the walls had actually fallen inward.“
George Davidson, professor for Geography, woke up from the tumult coming from the streets. He grabbed his watch on the desk and noted the length of a first quake – 60 seconds – followed by a second – again 20 to 40 seconds long. His observations – 5:12am in the morning – will later be used to determinate the official time of the great earthquake of San Francisco. Many people were still asleep and killed in their beds, those who escaped gathered in the streets. Despite the earthquake, most of the city seemed still intact and surprisingly quiet.
In 1906 San Francisco was already considered a great, but also corrupt, city with more than 400.000 inhabitants. Thanks to the discovery of gold in the rivers of California the city was quickly expanding into its surroundings. It was an important gateway to the Pacific and a modern trade place. The newest technology in film equipment was available in the shops. The earthquake of San Francisco will become the first natural disaster of this magnitude to be so well documented by photographs and film footage (even in color).
However, most buildings in San Francisco were poorly constructed and made of wood. San Francisco had burned to the ground six times in the past century and experienced strong earthquakes in 1865 and 1868, when 30 people were killed.
Police sergeant Jesse Cook was the first person to report a fire in a grocery in Clay Street. An hour later there were already fifty fires spotted in the entire city. The firefighters realized horrified that the water pipes in the underground were broken and the hydrants useless. The resulting firestorm will burn three days and will destroy 90 percent of the 28.000 buildings in San Francisco.
Journalist Arnold Genthe will take one of the most famous photos in history.
“I found that my hand cameras had been so damaged by the falling plaster as to be rendered useless. I went to Montgomery Street to the shop of George Kahn, my dealer, and asked him to lend me a camera. “Take anything you want. This place is going to burn up anyway.” I selected the best small camera, a 3A Kodak Special. I stuffed my pockets with films and started out….”

In Jackson Street, the owner of the “Hotaling´s Whiskey” distillery decides to fight the flames. He pays 80 men to sprinkle 5.000 barrels of whiskey with water pumped out from the sewer system. Later he will mock all those who claim that the earthquake was sent by god by coining a new advertising slogan for his company.
“If, as some say, God spanked the town, for being over frisky – why did He burn the churches down and save Hotaling´s Whiskey?“
Army troops were soon ordered into the city to help the firefighters and prevent panic and looting. Despite the fact that martial law was never proclaimed, the major authorized policeman and soldiers to shoot looting persons – “Obey orders or get shot” was the grim warning on the signboards.
Guion Dewey, a businessman from Virginia, wandering the streets of downtown San Francisco minutes after the quake, experienced the best and worst of human behavior, as he later wrote in a letter to his mother:
“I saw innocent men shot down by the irresponsible militia. I walked four miles to have my jaw set. A stranger tried to make me accept a $10 gold piece. I was threatened with death for trying to help a small girl drag a trunk from a burning house, where her father and mother had been killed. A strange man gave me raw eggs and milk . . . (the first food I had had for twenty-two hours). I saw a soldier shoot a horse because its driver allowed it to drink at a fire hose which had burst. I had a Catholic priest kneel by me in the park as I lay on a bed of alfalfa hay, covered with a piece of carpet, and pray to the Holy Father for relief for my pain. . . . I saw a poor woman, barefoot, told to “Go to Hell and be glad for it” for asking for a glass of milk at a dairyman’s wagon; she had in her arms a baby with its legs broken. I gave her a dollar and walked with her to the hospital. . . .I was pressed into service by an officer, who made me help to strike tents in front of the St. Francis Hotel when the order was issued to dynamite all buildings in the vicinity to save the hotel. I like him and hope to meet him again. When he saw I was hurt, which I had not told him, not yet having been bandaged, he took me to his own tent and gave me water and brandy and a clean handkerchief.“
The earthquake and the firestorms killed an estimated 3.000 to 4.000 people, destroyed 28.000 buildings and the infrastructure of the entire city. However, thanks to a quick rebuilt, just three years later most of San Francisco looked as if the earthquake never happened.
Seismology was still a young scientific discipline at the time of the earthquake in San Francisco. Worldwide there were only 96 seismographs operating, none of these in California. In the aftermath of the disaster, only three days later, the Governor of California announced the formation of the State Earthquake Investigation Commission, led by geologist Andrew C. Lawson of the University of California.
The commission focused on the San Andreas Rift, a nearby valley until then considered of minor interest and mapped geologically only in short sections. For two years Lawson and his team followed the rift, mapping ponds, streams and hills on foot and horseback. They recognized that the rift follows almost the entire coastline of California for more than 1.000 kilometers. During the April 18, earthquake, almost 480 kilometers of this large fault suddenly ruptured, displacing large sections horizontally, not vertically, as geologists had previously believed to be the source of earthquakes. The commission discovered that earthquakes can be generated also along so-called strike-slip faults.
The epicenter of the earthquake was at first located at the point with the largest observed displacement on land. However, today the epicenter is believed to be situated in the Pacific Ocean, in accordance with the seismic waves coming from the sea as observed by the first eyewitnesses.
The results of the scientific investigation of the San Francisco earthquake led Henry Fielding Reid, a geology professor at Johns Hopkins University in Maryland, to propose a new theory regarding the origin of earthquakes, later dubbed the “theory of elastic rebound“. Reid’s hypothesis will have a revolutionary impact on the young science of seismology.

Clash of the Titans: The Science behind the Iceberg that sank the Titanic
The tragedy of the “unsinkable” Titanic
– lost in the cold water of the Atlantic – became part of history and
pop culture, but the story of the main culprit that caused the disaster
is mostly forgotten and only vague descriptions and some photos exists
of the supposed iceberg(s). One famous photography taken from board of the cable ship “Minia“,
one of the first ships to reach the area in search for debris and
bodies, shows a tabular iceberg, an unusual shape for icebergs in the
northern Atlantic. The crew found debris and bodies floating in the
vicinity and the captain assured that this was the only iceberg near the
point of the collision. However most surviving Titanic testimonies
described later the infamous iceberg with a prominent peak or even two.

The passengers on the ship “Prinz Adalbert”, still unaware of the
disaster of the previous night, reported later to have noted a “red
smear” at the waterline of the white iceberg.

one of the first ships to reach the area in search for debris and
bodies. The crew found debris and bodies floating in the vicinity of the
depicted iceberg and the captain assured that this was the only iceberg
near the scene of the collision (after Titanic & Nautical Resource Center).

Another iceberg, photographed five days later from board of the German
ship “Bremen”, claimed to be the Titanic iceberg based on the vicinity
to the location of the disaster and the description of the iceberg
according to survivors. An "authentic"
photography of the iceberg that sank theTitanic was worth
a lot of money for the eager press, this also explain why so many photographs of icebergs were taken at the time.
Fig.6. Photography
taken from board of the ship “Birma” of the same iceberg as seen by the
passengers of the “Carpathia” (see also Fig.2.) – the first ship to approach the scene of
the disaster and save the surviving passengers of the Titanic – and
published at the time in the “Daily Sketch”. This iceberg has in fact
some remarkable similarities to the iceberg as described by survivors of
the disaster.
Despite the question if one of the photos shows really the culprit iceberg, the remarkably number of spotted icebergs emphasizes the notion that in 1912 a quite impressive number of these white titans reached such southern latitudes.

The icebergs encountered in the North
Atlantic originate mainly from the western coasts of Greenland, where
ice streams deliver large quantities of ice in the fjords which lead to
the Baffin Bay. Every year ten-thousand of small and large pieces of ice drop from the front of the glaciers and are pushed by the West Greenland Current slowly
to northern latitudes, far away from ship routes. Following first the
coast of Greenland this current is diverted by the Canadian coast to the
south, forming the Labrador Current that circumnavigates Newfoundland and delivers the iceberg to the warm Gulf Stream.
A more than 5.000km long journey full of obstacles and incessant
erosion by the sun, the water and the waves. Only estimated 1 to 2% of
large icebergs will, after a period of 1-3 years, reach latitude 45°N,
crossing one of the most important route for ships of the entire
Atlantic Ocean.

Apparently in 1912 icebergs were spotted remarkably often in this region and various hypotheses tried to explain
this “anomaly”. The years before 1912 were characterized by mild
winters in Europe and possibly the northern Atlantic. It was therefore
speculated that the (relative) warm temperatures increased the melting rate and activity of the calving glaciers on Greenland.
Also a strengthened Labrador Current, pushing cold water and icebergs much more to the south, was proposed to explain the ice field that in the cold night 100 years ago forced various ships to stop along the Atlantic route.
Both hypotheses are based on the recorded values of Sea Surface Temperature (see this diagram by the Woods Hole Oceanographic Institution), which show an alternation of a warm and cold period in 1900-1920.
A recent hypothesis – promoted by NG – proposes that an exceptional high tide prevented much of the larger icebergs to run, as normally would happen, on ground along the coasts of Baffin Bay. However considering that this tide occurred just some months before (January 1912) and the average velocity of an iceberg is low (0,7km/h~0,6mph), the Titanic iceberg had to take a straight course to arrive in time for his rendezvous with history – April 14, 1912.

Based on iceberg counts along the shores
of Labrador and later in the Atlantic, also the year 1912 don’t seem to
be necessarily such an anomalous event, but the disaster raised
considerably the interest (and maybe perception) of the public for
icebergs.

In the days after the disaster bypassing
ships encountered and photographed various icebergs. Some eyewitnesses
claim to have noted red paint on some of them; however there is no
conclusive evidence that one of these spotted white giants is really the
iceberg that sank the Titanic. At least some weeks later the culprit
iceberg, captured by the warm water of the Gulf Stream, melted and
disappeared forever into the Atlantic Ocean.

“I had a dream, which was not all a dream.
The bright sun was extinguish’d, and the stars
Did wander darkling in the eternal space,
Rayless, and pathless, and the icy earth
Swung blind and blackening in the moonless air;
Morn came and went – and came, and brought no day”

In the year 1816 Europe was slowly
recovering from the Napoleonic wars, ended just one year earlier. After
years of desperation and destruction people hoped for better times – but
the summer that came was rainy and cold and on the fields the crops did
not mature or rotted away, famine and diseases were the consequences.
Also the north-eastern states of the US experienced snowstorms and
frost in the middle of summer. The year 1816 has come to be known as the
“year without a summer.“
Fig.1. Development
of costs in the years 1816-17 of important articles of food in Europe.
Especially crops and bread, essential for the large and poor populations
on the continent, experienced a massive increase in costs due the
failed harvests. Meat was still a precious resource available only to a
limited group of persons at the time; the reduced livestock therefore
could still satisfy the demand (modified after ABEL 1974).
The strange behaviour of the weather was
unexplainable at the time. Nobody could imagine that the origins of the
strange phenomena were to be found on the opposite side of earth, where
an entire mountain had annihilated itself in the largest volcanic eruption of modern history.
The estimated 4.000m high volcano of Tambora on the island of Sumbawa in Indonesia erupted with an intensity of VEI 7 – 100x stronger than Mount St. Helens.
During the peak of eruption April 10, 1815 the mountain lost 1.300m
height and catapulted estimated two million tons of debris, particles
and sulphur components into the higher layers of the atmosphere. These
aerosols reduced the solar radiation on earth’s surface and influenced
worldwide weather patterns for years to come.
Thousands of people died by the direct effects of the four month lasting
eruption, like poisonous clouds and gas, large pyroclastic flows and
tsunamis. In the surrounding area of the volcano the vegetation was
killed and the soil poisoned for years. Many more suffered from the climatic effects and the aftermath of the eruption. Almost the entire northern
hemisphere, in a period with already cool climate, experienced an
ulterior drop of temperatures, famine and diseases spread over the
world.

Only one year later a detailed account of the catastrophe was published first in the “History of Java” (1817) by the English governor of Indonesia and naturalist Sir Thomas Stamford Bingley Raffles (1781-1826) and later incorporated in Lyell’s “Principles of Geology” (1850):
“Island of Sumbawa, 1815. – In
April, 1815, one of the most frightful eruptions recorded in history
occurred in the province of Tomboro, in the island of Sumbawa, about 200
miles from the eastern extremity of Java.
In the April of the year preceding the volcano had been observed in a state of considerable activity, ashes having fallen upon the decks of vessels which sailed past the coast. The eruption of 1815 began on the 5th of April, but was most violent on the 11th and 12th, and did not entirely cease till July. The sound of the explosions was heard in Sumatra, at the distance of 970 geographical miles in a direct line; and at Ternate, in an opposite direction, at the distance of 720 miles.
Out of a population of 12,000, in the province of Tomboro, only twenty-six individuals survived. Violent whirlwinds carried up men, horses, cattle, and whatever else came within their influence, into the air; tore up the largest trees by the roots, and covered the whole sea with floating timber. Great tracts of land were covered by lava, several streams of which, issuing from the crater of the Tomboro mountain, reached the sea. So heavy was the fall of ashes, that they broke into the Resident’s house at Bima, forty miles east of the volcano, and rendered it, as well as many other dwellings in the town, uninhabitable.
On the side of Java the ashes were carried to the distance of 300 miles, and 217 towards Celebes, in sufficient quantity to darken the air. The floating cinders to the westward of Sumatra formed, on the 12th of April, a mass two feet thick, and several miles in extent, through which ships with difficulty forced their way. The darkness occasioned in the daytime by the ashes in Java was so profound, that nothing equal to it was ever witnessed in the darkest night.
Although this volcanic dust when it fell was an impalpable powder, it was of considerable weight when compressed, a pint of it weighing twelve ounces and three quarters. “Some of the finest particles,” says Mr. Crawfurd, “were transported to the islands of Amboyna and Banda, which last is about 800 miles east from the site of the volcano, although the south-east monsoon was then at its height.” They must have been projected, therefore, into the upper regions of the atmosphere, where a counter current prevailed.
Along the sea-coast of Sumbawa, and the adjacent isles, the sea rose suddenly to the height of from two to twelve feet, a great wave rushing up the estuaries, and then suddenly subsiding. Although the wind at Bima was still during the whole time, the sea rolled in upon the shore, and filled the lower parts of the houses with water a foot deep. Every prow and boat was forced from the anchorage, and driven on shore.
The town called Tomboro, on the west side of Sumbawa, was overflowed by the sea, which encroached upon the shore so that the water remained permanently eighteen feet deep in places where there was land before. Here we may observe, that the amount of subsidence of land was apparent, in spite of the ashes, which would naturally have caused the limits of the coast to be extended.
The area over which tremulous noises and other volcanic effects extended, was 1000 English miles in circumference, including the whole of the Molucca Islands, Java, a considerable portion of Celebes, Sumatra, and Borneo. In the island of Amboyna, in the same month and year, the ground opened, threw out water, and then closed again.
In conclusion, I may remind the reader, that but for the accidental presence of Sir Stamford Raffles, then governor of Java, we should scarcely have heard in Europe of this tremendous catastrophe. He required all the residents in the various districts under his authority to send in a statement of the circumstances which occurred within their own knowledge; but, valuable as were their communications, they are often calculated to excite rather than to satisfy the curiosity of the geologist. They mention, that similar effects, though in a less degree, had, about seven years before, accompanied an eruption of Carang Assam, a volcano in the island of Bali, west of Sumatra; but no particulars of that great catastrophe are recorded.“

In the year 1725 the professor of medicine and personal physician of the bishop of the German town of Würzburg, Dr. Johann Bartholomäus Adam Beringer (1667-1738),
was approached by three chaps, who offered him the possibility to
purchase some strange stones they had found in the fields.
Beringer recognized the unique value of the discovery and paid a rich reward for these and further specimens. After a short time he possessed the greatest collection of stones displaying on the surface various bugs, molluscs, plants, birds, mammals, stars, suns and even Hebraic letters.
One year later, in 1726, Beringer published a monographic work with 14 sections and 21 plates depicting 204 specimens of his collection: the “Lithographia Wirceburgensis”, assuring the veracity of the stones as a divine miracle.
But then the scandal was revealed – the chaps admitted that the stones were artificially carved, incited by two peers of Beringer, the mathematician Jean Ignace Roderique (1697-1756) and the theologian Johann Georg von Eckhardt (1664-1730). The two scholars admitted that the fraud was their revenge for the presumptuous behaviour of Beringer and intended to expose his credulity and incompetence. The public was not amused by the childish behaviour of all the involved persons: The reputation of all the three scholars was ruined, Roderique and Eckhardt were forced to leave the city and Beringer tried to minimize the damage by destroying almost all of the printed copies and the printing plates of his book. He never recovered from the humiliation and died embittered years later.
Almost every student of earth sciences knows this or a similar version of the myth, often told in textbooks as warning of blind faith and argument from authority. The beautiful carved stones of limestone are today remembered as “Würzburger Lügensteine” – the infamous “lying stones of Würzburg“.

Almost every student of earth sciences knows this or a similar version of the myth, often told in textbooks as warning of blind faith and argument from authority. The beautiful carved stones of limestone are today remembered as “Würzburger Lügensteine” – the infamous “lying stones of Würzburg“.
However careful study of the still existing stones and the preserved
historic documents of the lawsuit that investigated the claims of fraud
at Beringer´s time depict a much more complicated “criminal case.”
Today 434 lying stones survive, 494 are
depicted in the Lithographia Wirceburgensis and Beringer himself claims
that he possessed more than 2.000. However considering the short period
in which the “discoveries” took place (less than one year) it seems more
reasonable to assume that this number is deliberately exaggerated.
Estimated 600 to 1.100 true lying stones seem a more plausible number.
Beringer affirms that he received or discovered the first stones in May of the year 1725. Between June and November he hired the two brothers Hehn, the chap Zänger and later a fourth person, which name is not recorded, to collect further stones on the presumed site of the first discovery.
Beringer began almost immediately to describe the various stones and ordered the printing plates for his book; he also published a preview of his work in October of 1725. Already then first doubts were cast on the veracity of the stones, but Beringer presented various witnesses that could testify that indeed the stones were found during the excavations on a hill near Würzburg. Johann Georg von Eckhardt, and later Jean Ignace Roderique, were send to investigate the site but couldn’t find any stone there. However they also couldn’t provide evidence to dismiss Beringer´s claims.
It is important to note that Beringer never affirmed that the stones were true petrifactions (as the petrified remains of organisms killed by the biblical flood) and he even states that the stones differ from the true petrifactions found in the hills near Würzburg. He discusses in great detail the various explanations proposed for the origin of petrifactions in the first chapters of “his” Lithographia (as a matter of fact the book is published as doctoral thesis under the name of one of Beringer´s students – Georg Ludwig Hueber – but his contribution is limited to an introduction of nine pages) and examines the various hypotheses, but dismiss all in favour of a literally “miracle”. God himself created these stones and the recognizable carving spurs (!) on the stones are only a trace of the power of god creating these figures.
In spring of 1726 Beringer received some rocks from the fourth chap, this time in fact fabricated by Roderique to reveal the artificial nature of the stones. The fraud is revealed, even in the presence of the bishop (the Lithographia is dedicated to him), but Beringer simply modifies some chapters of the Lithographia, still in press, claiming that it is now only proven that the last stones are fakes and the first generation is still evidence for (literally) god’s hand carving the rocks. Beringer is apparently so self-confident in his position that he initiates a process against the claims of fraud regarding his persona. In the process, that will last until after the publication of the Lithographia, the incriminated chaps will only admit to have sold the stones to Beringer, but not to have carved the figures. Considering the depictions of exotic animals and even Hebraic letters on the lying stones it is in fact difficult to image that people from a rural area with no naturalistic background would be able to execute such an elaborate hoax.
There is no doubt that the scholar Roderique manufactured some of the stones, however he arrived to Würzburg only in the winter 1725-1726, so he can not be responsible for the first generations of stones described by Beringer already in October of 1725. Roderique left Würzburg voluntarily in 1730, the revealed “scandal” had no influence on his career and he died as respected scholar and publisher years later. There is no evidence that Eckhart played a major role in the entire story, apart the first investigation of the supposed excavation site. Both Roderique and Eckhart had no need for revenge versus Beringer and were relatively unsuccessful in the attempt to discredit the lying stones, as they – or others, could never demonstrate that that the first stones were fakes.
But who then faked the first lying stones?
Beringer didn’t suffer too much from the supposed scandal, not only didn’t he even try to prevent the publication of the Lithographia after the first claims of fraud (there was still plenty of time left), but he retained his position and reputation. In 1767 even a second edition of the Lithographia was published with the original plates (not even touched by Beringer) of the first edition.
His hypothesis of divine intervention on the rocks was never ridiculed in a time when fossils were anyway considered the vestiges of a biblical flood. However it is true that after the newspapers revealed that it was possible to fake the stones (like done by Roderique) the lying stones could no longer be used to support uncritically the "divine crafted" hypothesis.
Only after Beringer´s death his strange behaviour, he remained unimpressed by all the claims of fraud, was interpreted by many authors as simple ignorance or even criminal stubbornness. But maybe he remained calm because he was sure that nobody could definitely prove that the first generations of stones were fakes, simply because he knew who carved the figures in the stones. Beringer had the naturalistic knowledge and probably also the contacts to professional craftsmen to perpetuate such an elaborate hoax – even if we never will know the entire truth, one fact is clear, the modern myth of the lying stones is itself a lie…
