Engraved Pigments Point to Ancient Symbol Tradition

Engraved pigments point to ancient symbolic tradition
Incisions on ochre from a South African cave suggest modern human behavior emerged around 100,000 years ago (Image: Geometric patterns incised on pieces of ancient pigment, such as these 100,000-year-old finds, may reveal the surprisingly ancient origins of modern human behavior.Credit: Courtesy of C.

Scientists excavating a Stone Age cave on South Africa’s southern coast have followed a trail of engraved pigments to what they suspect are the ancient roots of modern human behavior.
Analyses of 13 chunks of decorated red ochre (an iron oxide pigment) from Blombos Cave indicate that a cultural tradition of creating meaningful geometric designs stretched from around 100,000 to 75,000 years ago in southern Africa, say anthropologist Christopher Henshilwood of the University of the Witwatersrand in Johannesburg and his colleagues. Their report appears online and in an upcoming Journal of Human Evolution.
Much debate surrounds the issue of when and where language, religion, symbolic decorations and other facets of modern human behavior originated. Researchers such as Henshilwood hypothesize that modern human behavior developed gradually in Africa, beginning more than 100,000 years ago. Others posit that a brain-boosting genetic mutation around 50,000 years ago fostered modern behavior in Africa. Some researchers suspect that behavioral advances first appeared in Europe, Asia and Africa at that later time.
Possible examples of symbolic behavior from around 100,000 years ago — such as proposed human burials in the Middle East and pigment use in Africa — have been controversial.
"What makes the Blombos engravings different is that some of them appear to represent a deliberate will to produce a complex abstract design," Henshilwood says. “We have not before seen well-dated and unambiguous traces of this kind of behavior at 100,000 years ago.”
Further studies need to confirm that the ancient incisions were not the result of, say, slicing into ochre with stone tools in order to remove powder quickly, cautions anthropologist Curtis Marean of Arizona State University in Tempe, who studies ancient human behavior at another South African cave (SN: 10/20/07, p. 243). [Anyone looking at the patterns scored into the small pigment stones would probably conclude otherwise. One would not have to score a specific geometric pattern into a pigment stone in order to remove colored pigment to mix paint. Any way of pulverizing pigment off the stone would do, including just making gouges. This is just common sense.]
Even if the Blombos pigments contain intentional designs, fully modern human behavior — such as the use of figurative art (SN: 6/20/09, p. 11) — didn’t emerge until tens of thousands of years later, contends archaeologist Nicholas Conard of the University of Tuebingen, Germany. [Hmmm, could this contention possibly have anything to do with the fact that, for instance, the Willendorf Venus was found in Germany, and dates to c. 35,000 years ago?]
Henshilwood and study coauthor Francesco d’Errico of the University of Bordeaux I in Talence, France, disagree. In their view, the Blombos pigments bear intentionally fashioned designs that held some sort of meaning and were passed down the generations for 25,000 years. Thus, the two researchers say, it’s likely that a 100,000-year-old society already steeped in symbolic behavior originally produced the ochre engravings.
In 2002, Henshilwood’s team described evidence of symbolic engravings on two other ochre pieces from Blombos Cave. Those 77,000-year-old finds were excavated in 1999 and 2000.
Engraved chunks of pigment in the new analysis were unearthed during the same excavations. Specimens came from either of three sediment levels with estimated ages of 72,000 years, 77,000 years and 100,000 years.
A microscopic analysis indicates that ochre designs were made by holding a piece of pigment with one hand while impressing lines into the pigment with the tip of a stone tool. On several pieces, patterns covered areas that had first been ground down.
Geometric patterns on the ochre pieces include cross-hatched designs, branching lines, parallel lines and right angles. [See images at beginning of article].
Pigment powder had also been removed from many of the recovered ochre chunks. Incised patterns may have served as models for pigment designs applied to animal skins or other material, the scientists speculate.
Excavations of Blombos Cave sediment from before 100,000 years ago have begun. “The discovery of more, and perhaps even more striking, engravings is very possible,” Henshilwood says. [That remains to be seen...]

Schoolgirls clinch victory in national chess championship
Published Date: 11 June 2009
By Richard Marsden
BRAINY schoolgirls from South Yorkshire tested their tactics and concentration to the limit to win a national chess championship.
Evie Hollingworth, aged 14, and Megumi Parbrook, 11, from Sheffield, Francesca Fozard, 13, from Barnsley, and Anna Cunningham, 11, from Rotherham, made up two-thirds of the victorious under 14s girls Yorkshire team.
They were joined by Rebekah Brown, 14, from Leeds, and Amy Greenhough, 13, from Bradford, to win the day-long contest in Leicestershire.
Opponents were from Lincolnshire, Worcestershire, Kent, and reigning eight-times champions Surrey.
The competition involved three rounds of games lasting almost two hours each. Yorkshire got off to a stunning start, winning every match in the first round and remaining undefeated in the second with four wins and two draws.
Going into the last round, the team was two points ahead of Kent and after losing two games, it came down to a nailbiting finish resting on the result of the last game – Yorkshire against Kent.
Delighted team manager John Hipshon said: "It was a thrilling and tense finish. A victory for either player would have resulted in their team taking the title but our player kept her cool under pressure and won.
"It was a very tough competition at a high standard. To come away with the trophy is a real achievement."

Goddess Alive!
Well - knock me off my chair with a feather! The current issue (Issue No. 15 - Spring/Summer 2009) starts with a short piece (online) featuring what sure looks like a rock carving of a fecund female, popularly known as a "Venus": The Acheulian Ancient Mother: The Oldest Goddess in the World. Take a look!
The thing is, "[T]he figurine was found between two layers of volcanic ash, the upper one 232,000 and the lower one 800,000 years old."
Okay - so you're thinking this HAS to be wrong. And so did I - except earlier today (one of those synchronicity things that regularly crops up in my life), I just happened to briefly read at Science Daily (don't have a url) that so-called "modern man" dates back to about 200,000 years ago. So much for Cro-Magnon Man appearing 35,000 years ago like I was taught in high school years ago. Ha!
So, it is entirely possible that this little "Venus," beautifully shaped using the natural properties of the stone on which she was carved, is as old as "modern man," and possibly even older - much older. What is even more intriguing is that this discovery raises the possibility that the "hominids" who lived in this area where the Venus was found had enough cognitive abilities to create art that predated by far, the oldest representations of "art" of which we are aware; this was something of which the experts say only "modern man" was capable.
I need to do more research on this intriguing find from the Golan Heights in 1981.

Update: Shira Evans and Computer Labs for Kids
Here is the latest on Shira Evans' Foundation, Computer Labs for Kids, that provides free laptop computers and training on how to use them to underprivileged children around the world. I'm summarizing in my own words:
The Egypt trip has, unfortunately, been cancelled. However, thanks to a friend that Shira knows through ICC (Internet Chess Club), Shira will next be travelling to Portugal and she is very excited about this new project. I can't wait to hear about it.
You can follow Shira's projects at Facebook, where she posts her videos and updates on her projects. You can also find her videos at You Tube.
Shira wants to play a game of chess with me on ICC! LOL! All the years I was reporting on Shira's results at the various tournaments she played in as an American chess femme, all those emails we exchanged, it never occurred to me that Shira didn't realize that I am the worst chess player in the entire world and, quite possibly, the entire Universe. I'm nearly certain I didn't represent myself to her as a great WGM, for instance :))) Geez - I don't even have an account at ICC!
Oh oh, panic time...
Hmmm, okay, I just had a hot flash in my brain (I still occasionally get them even though I'm post-menopausal for nearly 10 years now). Would you pay $$$ to see me get my newly-toned and much trimmer butt handed to me on a chessboard by Ms. Shira? All $$$ would be donated directly to Computer Labs for Kids.
Well, just a thought. Who can I get as a trainer...

A Different Kind of Fraud at the Brooklyn Museum
Blast from the Past: Those Las Vegas Showgirls "Do" Tessellations!
(Image: Tiled ceiling showing use of tessellated patterns, Shiraz, Iran).
Goddess' truth! As I was looking up the definition of onomatopoeia for the previous post about domestication of cats, I grabbed my trusty 30+ year old edition of Webster's Collegiate Dictionary off the bookshelf in the den and flipped it open as I settled it above my computer keyboard; it opened to pages 1204 and 1205. On the upper right hand side, page 1205, are the key words "tessellation (to) tethering."
When I saw "tessellation" I immediately thought of a Las Vegas Showgirls article that Isis and I put together many moons ago! Check it out:

For further information on the blow-your-mind subject of tessellations:
Lots of cool tessellation graphics at Tessellations.org
Refresher on what a tessellation is from Math Forum: What Is a Tessellation?
The word tessellation is derived from the Latin word for tile - "tesserae" - as in mosaic tiles. Although the art of creating amazing mosaics out of small bits of colored clay or stone tiles was known from before the Roman period, my recollection is that it was the Persians under Islamic rule who took the art to its highest form, creating intricate geometrical colored patterns out of myriad tesserae and larger glazed bricks. See, for instance, Iran: Visual Arts: History of Iranian Tile. New Evidence on Domestication of Cats
(Image: Bastet, from the Louvre Museum, 26th Dynasty, 664 - 332 BCE)
It's a lengthy article. Here are the key points summarized neatly at Scientific American Online:
- Unlike other domesticated creatures, the house cat contributes little to human survival. Researchers have therefore wondered how and why cats came to live among people.
- Experts traditionally thought that the Egyptians were the first to domesticate the cat, some 3,600 years ago.
- But recent genetic and archaeological discoveries indicate that cat domestication began in the Fertile Crescent, perhaps around 10,000 years ago, when agriculture was getting under way.
- The findings suggest that cats started making themselves at home around people to take advantage of the mice and food scraps found in their settlements.
- To get a bead on when the taming of the cat began, we turned to the archaeological record. One recent find has proved especially informative in this regard. In 2004 Jean-Denis Vigne of the National Museum of Natural History in Paris and his colleagues reported unearthing the earliest evidence suggestive of humans keeping cats as pets. The discovery comes from the Mediterranean island of Cyprus, where 9,500 years ago an adult human of unknown gender was laid to rest in a shallow grave. An assortment of items accompanied the body—stone tools, a lump of iron oxide, a handful of seashells and, in its own tiny grave just 40 centimeters away, an eight-month-old cat, its body oriented in the same westward direction as the human’s. Because cats are not native to most Mediterranean islands, we know that people must have brought them over by boat, probably from the adjacent Levantine coast. Together the transport of cats to the island and the burial of the human with a cat indicate that people had a special, intentional relationship with cats nearly 10,000 years ago in the Middle East. This locale is consistent with the geographic origin we arrived at through our genetic analyses. It appears, then, that cats were being tamed just as humankind was establishing the first settlements in the part of the Middle East known as the Fertile Crescent.
- Although the exact timeline of cat domestication remains uncertain, long-known archaeological evidence affords some insight into the process. After the Cypriot find, the next oldest hints of an association between humans and cats are a feline molar tooth from an archaeological deposit in Israel dating to roughly 9,000 years ago and another tooth from Pakistan dating to around 4,000 years ago. Testament to full domestication comes from a much later period. A nearly 3,700-year-old ivory cat [c. 1700 BCE] statuette from Israel suggests the cat was a common sight around homes and villages in the Fertile Crescent before its introduction to Egypt. [Baloney!] This scenario makes sense, given that all the other domestic animals (except the donkey) and plants were introduced to the Nile Valley from the Fertile Crescent. But it is Egyptian paintings from the so-called New Kingdom period—Egypt’s golden era, which began nearly 3,600 years ago [c. 1500 BCE - after the Hyksos were kicked out rulership]—that provide the oldest known unmistakable depictions of full domestication. These paintings typically show cats poised under chairs, sometimes collared or tethered, and often eating from bowls or feeding on scraps. The abundance of these illustrations signifies that cats had become common members of Egyptian households by this time.
[Well known associations of the lion with the ancient Egyptian Sun God, RA, and the association of the lioness or lion-headed goddess as one of the "Eyes of Ra" - Sekhmet, an aspect of equally ancient Goddess Het-Hert (Hathor) indicate a much older association between the ancient Egyptians and cats. As far as I am aware, both of these deities pre-date the founding of the dynastic period in ancient Egypt, c. 3500-3400 BCE and are therefore at least 5500 to 5400 years old, and quite possibly older. See, for instance, this information from the Louvre Museum indicating that the bones of a cat were discovered in a predynastic tomb dating to around 4000 BCE - that is, about 6000 years ago].
Gruesome Evidence of Inca Human Sacrifice
The Sardonic Grin
This article gives new meaning to a well-known but poorly understood phrase!

Ancient Death-Smile Potion Decoded?
James Owen for National Geographic News
June 2, 2009
Thousands of years before the Joker gassed comic book victims into a grinning death, Phoenician colonists on the island of Sardinia were forcing smiles on the faces of the dead.
Now scientists say they know just how the ancient seafaring traders created the gruesome smiles some 2,800 years ago—not with a toxic gas like Batman's nemesis but with a plant-based potion.
And someday that plant might be used to Botox-like effect, perhaps reducing rather than adding smile lines, the researchers speculate.
Ancient Death Grins
By the eighth century B.C., Homer had coined the term "sardonic grin"—"sardonic" having its roots in "Sardinia"—in writings referring to the island's ritual killings via grimace-inducing potion.
Elderly people who could no longer care for themselves and criminals "were intoxicated with the sardonic herb and then killed by dropping from a high rock or by beating to death," according to the new study.
For centuries the herb's identity has been a mystery, but study leader Giovanni Appendino and colleagues say they have discovered a sardonic grin-inducing compound in a plant called hemlock water-dropwort.
The white-flowered plant grows on celery-like stalks along ponds and rivers on the island, now part of Italy.
Modern Suicide, Ancient Mystery
About a decade ago, a Sardinian shepherd committed suicide by eating a hemlock water-dropwort, leaving a corpse with a striking grin.
The death spurred study co-author Mauro Ballero, a botanist at the University of Cagliari in Sardinia, to study every dropwort-related fatality on the island in recent decades.
For the new study, Ballero and colleagues detailed the molecular structure of the plant's toxin and determined how it affects the human body.
Study leader Appendino, an organic chemist from the UniversitĂ degli Studi del Piemonte Orientale in Italy, said, "The compound is highly toxic and causes symptoms similar to those described by the ancients for the sardonic smile, including facial paralysis."
Hemlock water-dropwort "was already known to contain neurotoxins and was the most likely candidate for the sardonic herb," Appendino said.
The hairy buttercup (aka the Sardinian buttercup) was also a candidate, but that plant doesn't grow in the damp places mentioned in ancient texts, nor does it make sense in terms of its toxic properties, Appendino said.
"Besides, Sardinia is the only place all over the Mediterranean where [hemlock water-dropwort] grows," he added.
A Better Botox?
A member of the deadly hemlock family, the herb is especially dangerous because of its fragrant smell and sweet-tasting roots.
"Generally poisonous plants are bitter or in some way repel people," Appendino said.
Hemlock water-dropwort "is only the second case I know of a toxic plant that is actually attractive to our senses. People might easily eat it in a potion," he added—or perhaps apply it in a lotion.
Appendino speculates that the plant may prove to have a cosmetic application.
"It relaxes the muscles," he said, "so it removes wrinkles."
