Was Napoleon Bonaparte Jewish, or Even Descended from the Moors?

It has become possible recently to identify Napoleon’s dna from samples taken from male descendants of his brothers. Napoleon’s dna is unusual and distinctive, and—interestingly—turns out to be an example of Haplogroup E1b1b1c1, a group of Levantine origin, which suggest that Napoleon Bonaparte’s ultimate male descent was from ancient Phoenecian traders, or Sephardic Jews, or possibly even from the Moors, which did not keep him having blond hair as young man (which later darkened) and grey-blue eyes.

The flag of Corsica features a Moor’s Head, referring to the island’s medieval invasion by the Saracens.

If your Y-dna is from Haplogroup E1b1b1c1, you will want to drop by the Napoleon DNA Project to compare your own results.

Viking Hoard Found by Metal Detector in Silverdale, Lancashire

Archaeology, England, Treasure, Vikings

line

Australian News:


Darren Webster was meant to be going back to work after dropping his son off at home when, on a whim, he stopped by a field and decided to have a quick forage with his metal detector.

Within 20 minutes he made a discovery that was to introduce a new name to the turbulent history of medieval England.

One of the objects in a hoard of silver buried one metre down in the earth was a coin marked with the name of Airedeconut, thought to refer to Harthacnut, a previously unrecorded Viking king powerful enough to have his own currency in 10th-century Northumbria.

Mr Webster, who has a stone tile workshop in Yealand Conyers, Lancashire, said that he had permission to search in the field near his home in Silverdale but did not choose it for any particular reason.

“My machine was telling me that I’d found some kind of silver. So I was slightly disheartened when I saw a lead pot. It was as I was lifting it that silver pieces started falling out of it.”

Once the lead container had been prised open there were 201 silver objects, including 27 coins, ten arm-rings, six brooch fragments, two finger rings, a fine wire braid and 14 ingots.

There were also 141 fragments of metal known as hacksilver, which would have been used for barter.

Gareth Williams, curator of early medieval coins at the British Museum, where the discovery was announced yesterday, said that the hoard would have been worth a midsized herd of cows in the 10th century, and would probably fetch a “high five-figure sum” today.

The exact value will be determined by a panel of experts in the spring, when museums will be allowed to bid for it. The Lancaster City Museum has already expressed an interest.

Under the Treasure Act, Mr Webster will be awarded half the value of the hoard, and the remainder will be given to the owner of the field, who has asked to remain anonymous.

Why someone hid a small fortune is a mystery, but burying treasure is usually an attempt to keep valuables safe in uncertain times.

“It is a period of political instability,” said Dr Williams. “The Vikings of Dublin were expelled and came to the North of England. There was also the Battle of Tettenhall, on the outskirts of Wolverhampton, where several northern kings were killed.”

—————————————
Telegraph:


The hoard was placed in a lead box and buried underground at a time when the Anglo-Saxons were attempting to wrest control of the north of the country from the Vikings.

Yesterday, the central London museum unveiled the hoard, the fourth largest ever found, which included Anglo-Saxon, Anglo-Viking, German and Islamic coins.

In total there were 201 silver objects, including the 27 coins which date the burial around 900AD, around the time the Vikings had been expelled from Dublin and were fighting the Anglo-Saxons to keep control of the north of England.

It also includes also coins from the time of Alfred the Great, who reigned from 871 to 899, and from the Viking kingdom of Northumbria.

One silver denier, bears the name Charles. Others bear the name Airdeconut, a Viking ruler in northern England.

Officials said the inscription Airdeconut, appeared to be an attempt to represent the Scandinavian name Harthacnut.

They said this was because many Vikings had converted to Christianity within a generation of settling in Britain.

On the other side were the words DNS (Dominus) REX, which was arranged in the form of a cross.

“The design of the coin relates to known coins of the kings Siefredus and Cnut, who ruled the Viking kingdom of Northumbria around AD900, but Harthacnut is otherwise unrecorded,” a museum spokesman said.

“It is a very significant find. It is a very large haul and it is the fourth large Viking find in the UK. Because it is recently discovered there is lots of research to be done.”

Experts believe the hoard, which also includes 10 arm rings, two finger rings, 14 ingots, six brooch fragments and a fine wire braid which may have been worn as a necklace, could have been buried by a Viking warrior before he went into battle.

The collection of 10 bracelets and other jewellery are thought to have been worn to signify rank of the influential owner.

Dr Gareth Williams, the curator of early medieval coins at the museum, said: “Some of the coins reinforce the things we already know but with some of them it fills in the gaps where we didn’t even know we had gaps.

“It is always great when you get a new piece of evidence. This is the first new medieval King for at least 50 years and the first Viking King discovered since 1840. It is a very exciting find.”

It was found in September by Darren Webster, 39 using a metal detector on land around Silverdale, in north Lancashire.

Löwenmensch Reconstructed

Archaeology, Art, Löwenmensch

line

The Aurignacian culture of the Upper Paleolithic (Late Old Stone Age) flourished between 45,000 and 35,000 years ago (or so we think, theories of carbon dating are subject to revision).

The Aurignacians are generally awarded the title of being our earliest genuinely human ancestors in Europe on the basis of artistic achievement. It was they who produced the Hohle-Fels Venus, the Chauvet cave paintings, and the Stadel cave Löwenmensch (“Lion Man”), all powerfully moving, but cryptic and fundamentally incomprehensible to us, artistic expressions.

The last object, the Löwenmensch, was discovered in a cave in the Swabian Alps in 1939. WWII resulted in its being neglected for 30 years, but eventually scholar attention arrived. The fragments were assembled, and interpreted. First, as a deity or a shaman representing a lion god, later as (Gawd help us!) a “cave lioness” and an icon of Stone Age Feminism.

Near the end of the last century, a few more pieces were discovered, so scientists are now in the process of removing earlier “restored” bits and having a go at reassembling the original artifact absent recent interpolations. The results will be very interesting.

Scientists Find Probable Amerindian DNA in Iceland

DNA, History, Iceland, Indians, Vikings

line

The discovery of a new mitochondrial DNA (mtDNA) subclade (C1e) in Iceland of Haplogroup C, characteristic of population groups found in Northeast Asia and of Amerindians is identified in a new paper in the American Journal of Physical Anthropology as likely evidence of the presence in Iceland of matrilineal descent from American Indians encountered by Viking explorers of North America around the year 1000 A.D.

Abstract


Although most mtDNA lineages observed in contemporary Icelanders can be traced to neighboring populations in the British Isles and Scandinavia, one may have a more distant origin. This lineage belongs to haplogroup C1, one of a handful that was involved in the settlement of the Americas around 14,000 years ago. Contrary to an initial assumption that this lineage was a recent arrival, preliminary genealogical analyses revealed that the C1 lineage was present in the Icelandic mtDNA pool at least 300 years ago. This raised the intriguing possibility that the Icelandic C1 lineage could be traced to Viking voyages to the Americas that commenced in the 10th century. In an attempt to shed further light on the entry date of the C1 lineage into the Icelandic mtDNA pool and its geographical origin, we used the deCODE Genetics genealogical database to identify additional matrilineal ancestors that carry the C1 lineage and then sequenced the complete mtDNA genome of 11 contemporary C1 carriers from four different matrilines. Our results indicate a latest possible arrival date in Iceland of just prior to 1700 and a likely arrival date centuries earlier. Most surprisingly, we demonstrate that the Icelandic C1 lineage does not belong to any of the four known Native American (C1b, C1c, and C1d) or Asian (C1a) subclades of haplogroup C1. Rather, it is presently the only known member of a new subclade, C1e. While a Native American origin seems most likely for C1e, an Asian or European origin cannot be ruled out.

1500-Year-Old Bronze Buckle Fragment Found in 1000-Year-Old Alaska Eskimo House

The fragment of leather on the broken bronze buckle was carbon-dated to 600 A.D.

A University of Colorado Bouilder archeology team excavating a 1000-year-old Inupiat Eskimo house at Cape Espenberg on Alaska’s Seward Peninsula found a partial bronze artifact resembling a buckle, which is apparently even older.

Bronze-casting is a technology not known ever to have existed in any New World culture, so the artifact was presumably made in Asia and reached Alaska by some unknown early system of trade.

Viking Sunstone Made Navigation Possible on Cloudy Days

History, Navigation, Science, Vikings

line


A piece of Iceland spar.

A paper published on Tuesday in Proceedings of the Royal Society A: Mathematical Physical & Engineering Sciences may offer the explanation of how Viking mariners a thousand years ago were able to navigate the North Atlantic between Europe and the Old World, traveling great distances by sea in high latitudes in which cloudy weather frequently denied visibility of the sun.

Yahoo News explains:


Before the invention of the magnetic compass, navigating with a sundial would have been difficult, particularly on overcast days. Ancient Viking lore suggests that they had a magical tool to find the sun, even when the star was hidden.

Researchers have now discovered the crystal that would have made such a magical apparatus possible. The Vikings could have used a common calcite crystal, called an Icelandic spar, to find the sun in the high latitudes where they would have had to battle long twilights and cloudy skies to navigate. This special “sunstone” could find the direction of the sun even when it was out of view because it plays a trick with the light.

“The Vikings could have discovered this, simply by choosing a transparent crystal and looking through it through a small hole in a screen,” study researcher Guy Ropars wrote in an email to LiveScience. “The understanding of the complete mechanism and the knowledge of the polarization of light is not necessary.”

To use the crystal, the Vikings would have held the stone up to the center of the sky (from their perspective). When sunlight hits the crystal, that light gets polarized and broken into an “ordinary” and an “extraordinary” beam.

On a clear day, the Vikings would have rotated the crystal until the two beams lined up. Since these two beams line up and have the same brightness at only one angle, by noting where the sun is when this happens the Vikings could establish a reference point that could be used even when the sun wasn’t visible.

There are several other types of crystal that have this same property, but they wouldn’t have been too useful because they aren’t as clear or as common, the researchers said. The Icelandic spar that the researchers analyzed is very common along the coasts of Iceland, and is also common today in Brazil and Mexico.

While none of these Icelandic spar crystals has been found in a Viking settlement, one was recently discovered in an Elizabethan shipwreck from 1592 in the English Channel.

Guy Ropars, Gabriel Gorre, Albert Le Floch, Jay Enoch and Vasudevan Lakshminarayanan, “A depolarizer as a possible precise sunstone for Viking navigation by polarized skylight:”

Summary


Viking navigation from Norway to America in the northern latitudes remains a mystery for physicists, historians and archaeologists. Polarimetric methods using absorbing dichroic crystals as polarizers to detect a hidden Sun direction using the polarized skylight have led to controversies. Indeed, these techniques may lack in sensitivity, especially when the degree of polarization is low. Here, we demonstrate theoretically and experimentally that using the transparent common Iceland spar as a depolarizer, the Vikings could have performed a precise navigation under different conditions. Indeed, when simply rotated, such a birefringent crystal can completely depolarize, at the so-called isotropy point, any partially polarized state of light, allowing us to guess the direction of the Sun. By equalizing the intensities of the ordinary and extraordinary beams at the isotropy point, we show that the Sun direction can be determined easily, thanks to a simple sensitive differential two-image observation. A precision of a few degrees could be reached even under dark crepuscular conditions. The exciting recent discovery of such an Iceland spar in the Alderney Elizabethan ship that sank two centuries before the introduction of the polarization of light in optics may support the use of the calcite crystal for navigation purposes.

Another Paper Featuring Conclusions Unfavorable to AGW Assassinated

Climategate, Global Warming, Science, Soon-Baliunas 2003 Paper, Spencer-Braswell 2011 Paper, University of East Anglia CRU

Those of us who remember the Climategate scandal of 2009, when Russian Intelligence released damaging emails exchanged between Phil Jones, head of the University of East Anglia’s Climate Research Center and other principal figures like Penn State’s Michael Mann, will recall Jones promising Mann on July 8, 2004, that he and Kevin Trenberth (of the US National Center for Atmospheric Research) would keep dissenting papers out of the next IPCC report by hook or by crook:

“I can’t see either of these papers being in the next IPCC report. Kevin and I will keep them out somehow — even if we have to redefine what the peer-review literature is!”

A year earlier one of Phil Jones’ emails addressed to a wider group of colleagues promised a boycott of the Journal Climate Research, guilty of publishing an important paper by Willie Soon and Sallie Baliunas of the Harvard–Smithsonian Center for Astrophysics injurious to the cause of Warmism, if the editor responsible was not replaced.

March 11, 2003—“I will be emailing the journal to tell them I’m having nothing more to do with it until they rid themselves of this troublesome editor.”

The Soon-Baliunas paper is described by Wikipedia as having “reviewed 240 previously published papers and tried to find evidence for temperature anomalies in the last thousand years such as the Medieval warm period and the Little Ice Age. It concluded that ‘Across the world, many records reveal that the 20th century is probably not the warmest or a uniquely extreme climatic period of the last millennium.’ ”

The upshot of the 2003 Climate Research publication of a paper challenging the Warmist Industry consensus was a successful crackdown by Phil Jones and his allies.

Climate Research’s chief editor, Hans von Storch, was persuaded to torpedo the offending paper in the same journal which had published it: The review process had failed. An unworthy paper had been published which did not adequately taken into account opposing arguments. The editorial policy of board editor Chris de Frietas responsible for its publication was insufficiently rigorous.

Storch then announced in the same editorial that he intended to impose a new regime giving himself final say on any paper’s publication. The publisher refused to accept the proposed dictatorship, and Storch and four other editors subsequently resigned in a thorough bloodbath.

Universal denials were issued concerning reports that Messrs. Jones, Mann, and Trenberth had been responsible for all this. Storch publicly denied that the fix had been put in. It was just a case of “a bad paper.”

Well, what do you know? Here we are in 2011, and it’s déjà vu all over again.

This time the paper is by Roy Spencer and William D. Braswell and is titled On the Misdiagnosis of Climate Feedbacks from Variations in Earth’s Radiant Energy Balance. The paper appeared in Remote Sensing in July.

Fox News identified the new paper’s significance in the world of climate science:


Has a central tenant of global warming just collapsed?

Climate change forecasts have for years predicted that carbon dioxide would trap heat on Earth, and increases in the gas would lead to a planet-wide rise in temperatures, with devastating consequences for the environment.

But long-term data from NASA satellites seems to contradict the predictions dramatically, according to a new study.

“There is a huge discrepancy between the data and the forecasts that is especially big over the oceans,” said Dr. Roy Spencer, a research scientist at the University of Alabama in Huntsville and U.S. science team leader for the Advanced Microwave Scanning Radiometer—basically a big thermometer flying on NASA’s Aqua satellite.

“The satellite observations suggest there is much more energy lost to space during and after warming than the climate models show,” he said. The planet isn’t heating up, in other words.

But, what do you know? Instead of another important paper challenging one Anthropogenic Global Warming’s central tenets, we have another case of the editor of the same journal in which the dissenting paper appeared, reversing course, denouncing the recently published paper, and resigning!

Warmist Peter Gleick reports triumphantly in Forbes:


The staggering news today is that the editor of the journal that published the paper has just resigned, with a blistering editorial calling the Spencer and Braswell paper “fundamentally flawed,” with both “fundamental methodological errors” and “false claims.” That editor, Professor Wolfgang Wagner of the Vienna University of Technology in Austria, is a leading international expert in the field of remote sensing. In announcing his resignation, Professor Wagner says “With this step I would also like to personally protest against how the authors and like-minded climate sceptics have much exaggerated the paper’s conclusions in public statements.”

In his editorial resignation, Professor Wagner says the paper was reviewed by scientific experts that in hindsight had a predetermined bias in their views on climate that led them to miss the serious scientific flaws in the paper, including “ignoring all other observational data sets,” inappropriate influence from the “political views of the authors,” and the fact that comparable studies had already been refuted by the scientific community but were ignored by the authors. He summarizes:

    In other words, the problem I see with the paper by Spencer and Braswell is not that it declared a minority view (which was later unfortunately much exaggerated by the public media) but that it essentially ignored the scientific arguments of its opponents. This latter point was missed in the review process, explaining why I perceive this paper to be fundamentally flawed and therefore wrongly accepted by the journal. This regrettably brought me to the decision to resign as Editor-in-Chief―to make clear that the journal Remote Sensing takes the review process very seriously.

Isn’t it amazing? For the second time in under a decade, some feckless scientific journal has published a paper offering conclusions deeply injurious to AGW, and again, in otherwise unprecedented reversals, the journal’s editor has attacked his own journal’s paper ex post facto for alleged lack of rigor and for purportedly failing to do justice to its opponent’s arguments, and resigned.

Presumably, we can look forward momentarily to the next development: the denials by Wolfgang Wagner that Messrs. Jones, Mann, and Trenberth, and the other principals of the Catastrophist Industry had anything to do with any of this.

I would say it is remarkable that, even after their exposure in 2009, the Global Warming gangsters still have the chutzpah, along with the remaining prestige and power, to successfully arrange the strangling in the cradle of significant dissenting publications, smearing their adversaries with accusations of bad science and lack of rigor.

Connecticut Lion Came From South Dakota

The last confirmed (until now) mountain lion resident in the Northeastern United States was killed by a trapper in Somerset County, Maine in 1938.

Mountain lions are thought by the wildlife experts to have a habitat range of 50 to 350 square miles.

DNA tests demonstrate that a mountain lion which was struck and killed by a 2006 Hyundai Tucson SUV around 1:00 a.m. on June 11 on Wilbur Cross Parkway in the area of Exit 55 in Milford, Connecticut came from far away and seems to have set something of a record for mountain lion roaming.

Middletown (CT) Press:


The Connecticut Department of Energy and Environmental Protection said today that results of genetic tests show that the mountain lion killed in Milford in June made its way to the state from the Black Hills region of South Dakota and is an animal whose movements were actually tracked and recorded as it made its way through Minnesota and Wisconsin.

Genetic tests also show that it is likely that the mountain lion killed when it was hit by a car June 11 on the Wilbur Cross Parkway in Milford was the same one that had been seen earlier that month in Greenwich.

Gold earrings depicting the goddess Nike [Victory]. Hellenistic (Late 4th Century B.C), Varna Archaeological Museum, Varna, Bulgaria

Yesterday, a Facebook friend Ekaterina Ilieva Ilieva posted a photograph of these extraordinary Hellenistic portraits of the Greek goddess Nike in the form of earrings.

(The earrings can be seen worn today in a 0:26 video here.)

I wanted to quote a favorite passage of mine from Xenophon illustrating the importance of Nike to Greek soldiers in the same period, but Facebook’s programmed formatting truncated the quotation, so I’m making my intended comment into a blog post.

Xenophon’s Anabasis is an account of the Middle Eastern campaign of ten thousand Greek mercenaries employed by Cyrus the Younger in an attempt to wrest the throne of Persia from his brother Artaxerxes II in 401 B.C.

Xenophon’s account of the Battle of Cunaxa, which took place 70 km. north of Baghdad on the left bank of the Euphrates, contains reference to the Greeks invoking Nike in the watchwords selected before the battle.

Anabasis, A, 8.6-8.17.:

Κῦρος δὲ καὶ ἱππεῖς τούτου ὅσον ἑξακόσιοι, ὡπλισμένοι θώραξι μὲν αὐτοὶ καὶ παραμηριδίοις καὶ κράνεσι πάντες πλὴν Κύρου: Κῦρος δὲ ψιλὴν ἔχων τὴν κεφαλὴν εἰς τὴν μάχην καθίστατο. ...

καὶ ἐν τούτῳ τῷ καιρῷ τὸ μὲν βαρβαρικὸν στράτευμα ὁμαλῶς προῄει, τὸ δὲ Ἑλληνικὸν ἔτι ἐν τῷ αὐτῷ μένον συνετάττετο ἐκ τῶν ἔτι προσιόντων. καὶ ὁ Κῦρος παρελαύνων οὐ πάνυ πρὸς αὐτῷ στρατεύματι κατεθεᾶτο ἑκατέρωσε ἀποβλέπων εἴς τε τοὺς πολεμίους καὶ τοὺς φίλους.

ἰδὼν δὲ αὐτὸν ἀπὸ τοῦ Ἑλληνικοῦ Ξενοφῶν Ἀθηναῖος, πελάσας ὡς συναντῆσαι ἤρετο εἴ τι παραγγέλλοι: ὁ δ᾽ ἐπιστήσας εἶπε καὶ λέγειν ἐκέλευε πᾶσιν ὅτι καὶ τὰ ἱερὰ καλὰ καὶ τὰ σφάγια καλά.

ταῦτα δὲ λέγων θορύβου ἤκουσε διὰ τῶν τάξεων ἰόντος, καὶ ἤρετο τίς ὁ θόρυβος εἴη. ὁ δὲ [Κλέαρχος] εἶπεν ὅτι σύνθημα παρέρχεται δεύτερον ἤδη. καὶ ὃς ἐθαύμασε τίς παραγγέλλει καὶ ἤρετο ὅ τι εἴη τὸ σύνθημα. ὁ δ᾽ ἀπεκρίνατο: Ζεὺς σωτὴρ καὶ νίκη.

ὁ δὲ Κῦρος ἀκούσας,—ἀλλὰ δέχομαί τε, ἔφη, καὶ τοῦτο ἔστω. ταῦτα δ᾽ εἰπὼν εἰς τὴν αὑτοῦ χώραν ἀπήλαυνε. καὶ οὐκέτι τρία ἢ τέτταρα στάδια διειχέτην τὼ φάλαγγε ἀπ᾽ ἀλλήλων ἡνίκα ἐπαιάνιζόν τε οἱ Ἕλληνες καὶ ἤρχοντο ἀντίοι ἰέναι τοῖς πολεμίοις.


Cyrus was with his bodyguard of cavalry about six hundred strong, all armed with corselets like Cyrus, and cuirasses and helmets; but not so Cyrus: he went into battle with head unhelmeted. ...

At this time the barbarian army was evenly advancing, and the Hellenic division was still riveted to the spot, completing its formation as the various contingents came up. Cyrus, riding past at some distance from the lines, glanced his eye first in one direction and then in the other, so as to take a complete survey of friends and foes;

when Xenophon the Athenian, seeing him, rode up from the Hellenic quarter to meet him, asking him whether he had any orders to give. Cyrus, pulling up his horse, begged him to make the announcement generally known that the omens from the victims, internal and external alike, were good.

While he was still speaking, he heard a confused murmur passing through the ranks, and asked what it meant. The other replied that it was the watchword being passed down for the second time. Cyrus wondered who had given the order, and asked what the watchword was. On being told it was “Zeus the Saviour and Victory,” he replied,

“I accept it; so let it be,” and with that remark rode away to his own position. And now the two battle lines were no more than three or four furlongs apart, when the Hellenes began chanting the paean, and at the same time advanced against the enemy.

Iceman’s Last Meal: Ibex

DNA, Iceman, Science

line


South Tyrol Museum of Archaeology photo

Science quotes, from a lecture given at the 7th World Congress on Mummy Studies, the latest findings concerning Europe’s oldest natural human mummy, found in September 1991 in the Ötztal Alps, near Hauslabjoch on the border between Austria and Italy and usually referred to as Ötzi or the Iceman.


Less than 2 hours before he hiked his last steps in the Tyrolean Alps 5000 years ago, Ötzi the Iceman fueled up on a last meal of ibex meat. That was the conclusion of a talk here last week at the 7th World Congress on Mummy Studies, during which researchers—armed with Ötzi’s newly sequenced genome and a detailed dental analysis—also concluded that the Iceman had brown eyes and probably wasn’t much of a tooth brusher.

The Iceman, discovered in the Italian Alps in 1991 some 5200 years after his death, has been a gold mine of information about Neolithic life, as researchers have extensively studied his gear—copper ax, hide and leather clothing, and accessories—and his body. Previous research on the Iceman’s meals focused on fecal material removed from his bowels. The contents showed that he dined on red deer meat and possibly cereal some 4 hours before his death.

But a team led by microbiologist Frank Maixner of the Institute for Mummies and the Iceman in Bolzano, Italy, recently reexamined computed tomography scans taken in 2005 and spotted, for the first time, the Iceman’s stomach. As the researchers reported at the meeting, the organ had moved upward to an unusual position, and it looked full. When they took a sample of the stomach contents and sequenced the DNA of the animal fibers they found, they discovered that Ötzi, just 30 to 120 minutes before his death, had dined on the meat of an Alpine ibex, an animal that frequents high elevations and whose body parts were once thought to possess medicinal qualities.

The new findings are “cutting edge” says Niels Lynnerup, a specialist in forensic medicine at the University of Copenhagen. “We are now inching our way to the last minutes of the Iceman.”

In a separate presentation, dentist Roger Seiler and anatomist Frank Rühli of the Centre for Evolutionary Medicine at the University of Zürich, examined the dental health of the Iceman, who probably died between the age of 35 and 40. Previously, researchers examining radiological images of his teeth discerned no trace of cavities or other dental problems. But the Swiss team created new three-dimensional images of the ancient traveler’s dentition. These showed that the Iceman suffered a blunt force trauma to two teeth—possibly a blow to the mouth—at least several days before his death and was plagued by both periodontal disease and cavities. The cavities, Seiler said in his talk, confirm that the Iceman ate a diet abounding in carbohydrates, such as bread or cereal, and reveal that he possessed a “heavy bacterial dose on these teeth.”
