CHINESE PICTOGRAPH PAINT CONTAINS HUMAN BLOOD:

How well a painted image will last on a cliff or boulder depends upon a number of factors. One factor, of course, is the kind of rock it is painted on, how hard or how soft? Another factor is the weather itself and the sites exposure to it. Is it directly in the Sun’s fading rays, is it in a location that is hit by rain, etc.? Another, and perhaps most important, factor is the composition of the paint itself. Is the pigment durable or fugitive? How thoroughly does the binder in the paint harden and hold on to the rock surface?

The images painted in one section of China have long mystified scientists with their clarity and appartent durability. “The Zuojiang Huashan Rock  Art Cultural Landscape was created over the course of nearly 700 years, between the fifth century BCE and the second century CE, by the Luoyue people – a matriarchal, hunter-fisher-gatherer society that lived in southern China. The images are found across 80 sites along a 260-kilometer stretch of river cliffs. Given that the area is battered by regular monsoons, the art is remarkably intact, especially compared with murals made hundreds of years later in other parts of the country.” (Sagar 2026) Normally, frequent monsoon rains would be thought to doom painted images to quick destruction.

These painted images, however, act very different – they are exceedingly durable. “The pigments are so firmly bonded to the bedrock that when peeling occurs, it is the limestone layer itself that detaches along with the pigments,” says Meng Wu, a chemist at Shandong University.  “The material stability of this art has long been an unsolved mystery.” (Sagar 2026)

“These paintings are bound to the rock so well that scientists had to use electric drills to scrape off samples for testing, which revealed that the paint contained lime, red clay, and blood from women who’d just given birth.” (Spitz 2026) The most surprising component of the paint used was blood, which came from both humans and animals. “The human portion contained two proteins that were linked to pregnancy, breastfeeding, and female reproductive biology. Therefore the team concluded that these proteins likely came from women who had very recently given birth, and that the blood came from routine postpartum bleeding.” (Spitz 2026) This is a likelihood, not a certainty, as the proteins in question are not totally unique to women and childbirth. Much of the durability of the red paint is due to the lime and red clay ingredients setting up in a reaction much like cement. Then, adding the proteins from blood, we can expect this to only enhance the durability of the paint.

As the Luoyue creators of this rock art are believed by historians to have been a matriarchal society, the use of postpartum blood in the paint may have had a deeply spiritual significance to the people. Therefore the act of creating the rock art may have also involved significant ritual contexts. At least that makes a great deal of sense.

CARVED IVORY BIRDS FROM HOHLE FELS CAVE:

Hohle Fels ('hollow rock') cave. Internet image, public domain.

For many years excavations have been underway at theh caves of the Ach Valley of the Swabian Jura, near Schelkiingen in southwestern Germany. These sites, particularly the caves Hohle Fels and Geissenklosterle, have produced an amazing number of carved ivory, antler and bone figurines along with other artifacts.

“The cave site of Hohle Fels was occupied during the Aurignacian period of prehistory (43,000 to 28,000 years before present), when early humans – thrived in Europe following the disappearance of the Neanderthals. These groups created an explosion of art, some of which had never been seen before in human history, including so-called Venus figurines, musical instruments, elaborate jewelry and cave paintings. Much of this art involved drawing and carving animals that the Aurignacian people would have seen on a day-to-day basis.” (Killgrove 2025)

Sculptures recovered from Hohle Fels include a small bird assumed to represent a water bird, animal figurines, a therianthrope known as the Lion Man, a flute (made from a vulture’s femur) and the famous Hohle Fels Venus. “The Hohle Fels bird is not the oldest figurative sculpture in Europe. That title has been taken by another discovery from the same cave in 2008: the Venus of Hohle Fels, a sculpture of a woman with exaggerated breasts and thighs, which was created 41,000 years ago.” (Killgrove 2025) On 18 July 2026 I published an article on RockArtBlog with the title “CLAVIFORM, VENUS OR STEATOPYGIA?” which questioned the enlarged buttocks seen on Paleolithic Venus figures and in some rock art, suggesting that it might represent the phenomenon of steatopygia.

Does this collection of work represent the beginning of figurative sculpture in Western civilization? Ewen Calloway suggest just that. “The entire collection of ivory carvings at Hohle Fels suggests that something very new was happening around 40,000 years ago in the south German mountains, as the people who created the Aurignacian culture invented types of figurative art and music akin to what we have today.” (Killgrove 2025)

These carvings strike the modern eye as extremely interesting, as if we have not changed that much in the period between their creation in the Aurignacian and now. “There’s something magical about these pieces,’ says Nicholas Conard, an archeologist at the University of Tubingen in Germany, who has led the excavation of Hohle Fels since the late 1990s. Conard argues that the artistic capabilities on display at Hohle Fels and nearby caves mark a shift in cognitive and cultural sophistication that might have helped these humans to flourish in ice-age Europe, when other groups vanished. He now hopes to test this theory by collecting ancient DNA from the Hohle Fels cave sediments.” (Callaway 2026) This would, at least, allow him to determine whether the carvings were made by modern humans, or our predecessors in Eutope.

Now, new discoveries at Hohle Fels have made the news. During the  2025 field season, Alexander Janas, an archeologist at the Senckenberg Center for Human Evolution and Paleoenvironment in Tubinge, Germany, discovered two more miniature bird carvings thought to resemble ptarmigans. “This week, Janas and his colleagues announced their latest treasures: a pair of tiny bird figurines carved from mammoth ivory, and vulture bone flute fragments, discovered during the 2025 field season. The artifacts were unveiled at the Museum of Prehistory and Ice Age Art in Blaubeuren, Germany, on 29 July.” (Callaway 2026) These two new birds are indeed tiny, measuring 2 – 3 cm. each.

And, as I said above, we immediately find these birds charming. They are cute. What else might be waiting to be discovered?

CROATIAN CAVE ART IS THE FIRST KNOWN IN THE BALKANS:

Romuald's Cave, Croatia. Internet image, public domain.

A recent discovery has provided “the first evidence for Upper Paleolithic figurative rock art from the Balkan region. These findings expand the geographic distribution of Upper Paleolithic rock art beyond the limits of Western Europe, contribute to filling the ‘rock art gap’ in an understudied research area and illuminate the geographic complexity of early symbolic behavior and its implications for understanding the Upper Paleolithic cultural mosaic.” (Ruiz-Redondo et al. 2019) The mystery has been that humans (and pre-humans) certainly lived there so where is the art that they decorated caves with farther north and west?

Bison, Romuald's Cave, Croatia. Photograph by Ruiz Redondo, figure 3, page 302.

Cave art was unknown in the Balkans and this project wanted to look into that. “The study’s author Aitor Ruiz-Redondo, and archeologist at the University of Southampton in the U.K., started looking for cave art in the region as part of a French-funded project. Ruiz-Redondo and his colleagues surveyed more than 60 prehistoric caves and rock shelters across Bosnia and Herzegovina, Croatia, Montenegro and Serbia; Romualdova Cave was one of just two sites that had clear evidence of Paleolithic rock art.” (Gannon 2019) Not only did they demonstrate admirable patience and tenacity, I find it interesting that their efforts are reportedly French-funded.

Tracing of the ibex, vertical lines, and triangular element by Ruiz Redondo, figure 4, page 303B.

People lived there, people traveled there, so why had no art been discovered? “While these discoveries have significantly modified previous assumptions on the origins of art, important gaps remain in our understanding of Pleistocene symbolism. In particular, there are entire regions that have yielded very little evidence concerning the rock art of anatomically modern humans. The Balkan Peninsula represents one of these regions; no Upper Paleolithic rock art has been discovered in the area between the sites of Fumane in Italy and Coliboaia in Romania - a distance of approximately 1000km— with the exception of the non-figurative engravings at Badanj Cave in Bosnia-Herzegovina and a possible Paleolithic painting at Sela’cka 3 in Serbia. A number of hypotheses could explain this gap. It could be argued, for example, that while the Upper Paleolithic groups in this area created symbolic objects (including portable art and personal ornaments), they did not develop a rock art tradition. Moreover, geological and environmental conditions may explain the absence of rock art in Central and Eastern Europe.” (Ruiz-Redondo et al. 2019:298) All over the world ancient peoples had cave and rock art traditions, so it makes little sense to me to say that maybe “they did not develop a rock art tradition.”

The survey of Romuald's Cave turned up a total of 44 red-painted images divided into four panels, including two badly preserved anthropomorphs, one of which appears to have an erection. (Wikipedia)

One factor, of course, is that you do not usually find what you are not looking for. “In comparison to Western Europe, the lack of a well-established regional research tradition is an important factor in explaining the absence of Upper Paleolithic rock art sites in the area. This may explain, for instance, why fewer than 50 Upper Paleolithic sites have been discovered in the combined area of Croatia, Bosnia-Herzegovina, Serbia and Montenegro (approximately 210 000km2), whereas 235 sites have been documented in the French region of Dordogne alone - an area 23 times smaller (approximately 9000km2). The disparity in the number of rock art sites is surprising, as the Balkans were probably one of the main routes into Europe for anatomically modern humans. (Ruiz-Redondo et al. 2019:298) So why no more remaining art, humans leave traces behind everywhere they go?

"Although the precise chronology of the Romualdova Pe’cina art remains unknown, its discovery represents a milestone among recent developments in the study of Paleolithic art. This cave contains the first evidence of figurative Upper Paleolithic rock art on the Balkan Peninsula. Hence, these paintings enlarge the geographic distribution of European rock art significantly, once again calling into question the traditional paradigm that assumes Upper Paleolithic cave art to be a Western European phenomenon. The discovery establishes the presence of figurative rock art in South-eastern Europe, illuminating the symbolic culture of Upper Paleolithic Balkan populations and the potential links between them and Western European groups. While this research modifies our perception of the Upper Paleolithic cultures that inhabited the Balkans, these advances constitute only a small step towards understanding the implications of the spread of Upper Paleolithic rock art, and the cultural links between Western Europe and the Balkan Peninsula.” (Ruiz-Redondo et al. 2019:310)  This discovery adds fuel to the old saying that every answer you find raises at least two new questions.

Panel with anthropomorphs, Tracing by Ruiz Redondo, figure 5, page 304B. (image sharpened with chatGPT)

“The presence of Paleolithic figurative art here raises several archaeological questions: could this art have originated independently, outside of Western Europe, or could it represent cultural diffusion from West to East? Do its particular features support the existence of close links with South-west European populations? Future research in the Balkans will contribute further information to address these questions. Additional research at Romualdova Pe’cina will be conducted to refine the chronology of the rock art and determine its chaîne operatoire. In the meantime, this discovery provides new data to reignite the debate about the spread of Upper Paleolithic parietal symbolism, and serves to emphasize the need for further archaeological exploration of long-neglected areas: the terra incognita of Paleolithic rock art.” (Ruiz-Redondo et al. 2019:310)

The author of the paper, Aitor Ruiz-Redondo who is associated with the University of Bordeaux and the University of Southampton, concluded “While this research modifies our perception of the Upper Paleolithic cultures that inhabited the Balkans, these advances constitute only a small step towards understanding the implications of the spread of Upper Paleolithic rock art, and the cultural links between Western Europe and the Balkan Peninsula. The presence of Paleolithic figurative art here raises several archaeological questions: could this art have originated independently, outside of Western Europe, or could it represent cultural diffusion from West to East? Do its particular features support the existence of close links with South-west European populations? Future research in the Balkans will contribute further information to address these questions.” (Ruiz-Redondo et al. 2019:310)

Discovery of new rock art is always of great interest, even more so in a region where it had been unknown before. We look forward with great interest to their future conclusions.

REDISCOVERED LATE UPPER PALEOLITHIC IMAGERY IN A CAVE IN BRITAIN:

 

Bacon Hole cave, Gower Peninsula, South Wales. Photograph from Nash et al., 2026, figure 2.

The oldest cave art in Britain has been essentially rediscovered in Bacon Hole cave, on Gower Peninsula in South Wales. First seen in 1912 by Henri Breuil and Professor William Sollas they were called the first Paleolithic cave art in Britain. This was, however, dismissed by skeptics and subsequently ignored and all but forgotten, until recently. The painted marks have been looked up again and reexamined by scientists (Arnold 2026). Records of the cave painting, however, still existed.

 

The first photograph of the panel, taken in 1913 by W.L. Morgan. From Nash et al., 2026, figure 6.

“Following the rediscovery of the painted panel in 2022, the First Art team, in collaboration with dating specialists from the University of Southhampton, conducted two expeditions to Bacon Hole in 2023 and 2024. Both visits were commissioned by the National Trust and scheduled outside the bat hibernation season (October to April). The primary aim of these visits was to create a photographic record of the wall sections within the eastern side chamber, focusing particularly on the area surrounding the painted panel.” (Nash et al. 2026) The painting was rediscovered in September 2022. The international team of scientists conducted pigment analysis looking for organic residues, and collected samples from calcite flows for Uranium-Thorium dating on a vertical painted surface within a side chamber. (Nash et al. 2026) It is, perhaps, of note that the investigation occurred outside of bat hibernation season. This may have been done out of consideration for the wildlife, but my guess would be that it was prompted by the range of viruses carried by bats.

 

The panel as photographed (left) and then processed with dStretch (right). From Nash et al., 2026, figure 9.

The teams did a quite complete job of studying and sampling the paint as well as the calcite layers on the cave wall. “In addition to the photographic survey, the painted surfaces originally discovered by Breuil and Sollas in 1912 were sampled to establish potential minimum and maximum date ranges. A total of twelve samples (six from each expedition) were collected. These included samples for both dating purposes (calcite overlapping pigments) and pigment geochemical analysis. The latter aimed to identify potential organic and inorganic binders using Attenuated Total Reflectance Fourier Transform Infrared (ATR-FTIR) spectroscopy and Micro-Raman analysis.” (Nash et al. 2026)

 

The samples taken for Uranium-Thorium dating revealed a range of dates with the oldest being 15.7 ka (at a 95% confidence level). (Nash et al. 2026) Other dates came back from more recent eras, such as the Bronze Age.

Locations sampled on the panel. From Nash et al., 2026, figure 10.

The conclusions of the teams back up the original estimates by Breuil and Sollas. "Based on the evidence gathered from the two fieldwork visits, we concur with the original interpretation proposed by Breuil and Sollas in 1912 - that the horizontal lines (or streaks) represent anthropogenic activity. The painted lines are arranged horizontally and are equidistant from one another, indicating a deliberate and structured patternn. Furthermore, the hematite used to produce the ten lines likely derives from a single source, probably located at the rear of the side chamber" (Nash et al. 2026).

Bacon Hole also has a wide range of images, scribbles and initials from since the time of the original painting (see Nash et al. below).

THE HIDDEN MOUNTAIN DECALOGUE STONE, LOS LUNAS, NEW MEXICO:

This is a column on a subject that I have long wrestled with in my own mind. It is the epigraphic question of prehistoric inscriptions in Old World scripts in the New World. I became aware of the arguments pro and con through many years of friendship with Bill McGlone. That friendship with Bill probably makes this a more subjective column than an objective one.

Hidden Mountain, New Mexico. Internet image, public domain.

I first met Bill McGlone in the mid-70s in Albuquerque, New Mexico. He had only recently become interested in epigraphy and was, at that time, convinced that there were examples of Ogam in southeastern Colorado. I called him to introduce myself and he graciously invited us to visit at his home where he and I debated rock art until my poor wife could stand it no longer. He later moved to La Junta, Colorado, to be closer to the subject that so fascinated him, and on frequent visits he and I would have many late night debates about epigraphy. We had to agree to disagree because I could not accept theories about prehistoric Old World visitors to southeast Colorado and Bill was a believer. He later dialed back his enthusiasm on Ogam in the New World considerably (although I don't know that he gave it up entirely) because he had shifted his interest to the subject of possible Near Eastern and ancient North African inscriptions in southeastern Colorado. In that enthusiasm Bill and his partner Phil Leonard visited and intensely studied many, many sites, and became quite conversant with the subject of epigraphy. Their enthusiasm led to a level of expertise that allowed them to be quite objective on certain aspects of the subject, and over the years they went on to debunk many fraudulent epigraphic  claims such as those of Barry Fell, although they still believed that there were some examples that were authentic.

The Decalogue Stone inscription. Internet image, public domain.

One site that they studied was the Decalogue Stone, on Hidden Mountain, 16 miles from Los Lunas, New Mexico. "The Los Lunas Decalogue Stone is a large boulder on the side of Hidden Mountain, near Los Lunas, New Mexico, about 35 miles (56 km) south of Albuquerque, that bears a very regular inscription carved into a flat panel. The stone is also known as the Los Lunas Mystery Stone or Commandment Rock." (Wikipedia)

And, in spite of their openness to epigraphic arguments, McGlone and Leonard decided that the Decalogue Stone inscription is a hoax (Personal communication with Bill McGlone). This conclusion is shared by almost any archaeologist who has ever studied the subject.

“One argument against the stone’s antiquity is its apparent use of modern Hebrew (or otherwise atypical) punctuation, though amateur epigrapher Barry Fell argued that the punctuation is consistent with antiquity. Other researchers dismiss the inscription based on the numerous stylistic and grammatical errors that appear in the inscription.

According to archaeologist Kenneth Feder, ‘the stone is almost certainly a fake.’ He points out that ‘the flat face of the stone shows a very sharp, crisp inscription. . .’ His main concern is the lack of any archaeological context. He argues that to get to the location of the stone would have required whoever inscribed it to have ‘stopped along the way, encamped, eaten food, broken things, disposed of trash, performed rituals, and so on. And those actions should have left a trail of physical archaeological evidence across the  greater American Southwest, discovery of which would undeniably prove the existence of foreigners in New Mexico in antiquity with a demonstrably ancient Hebrew material culture. . .’ and states that ‘There are no pre-Columbian ancient Hebrew settlements, no sites containing the everyday detritus of a band of Hebrews, nothing that even a cursory knowledge of now the archaeological record forms would demand there would be. From an archaeological standpoint, that’s plainly impossible.’” (Wikipedia)

The inscription and Barry Fell's translation. From Fell's book 'America BC.' (Image sharpened by chatGPT).

“British Archaeologist Keith Fitzpatrick-Matthews has concluded that ‘Viewed dispassionately, the Los Lunas inscription is a clear, but well constructed forgery (for its day). Despite the claims of high antiquity, there are features of the text (such as the mixing of letter forms between two separate alphabets) that are much more likely to derive from the work of a modern forger than from an ancient Hebrew or Samaritan scribe. The evidence for its origin is poor, but a comparison with the Bat Creek Stone suggests that it is a Mormon forgery. The ‘Mormon Battalion’, which was part of the US Army during the Mexican War, is known to have marched from Santa Fe down the Rio Grande Valley, passing close by, and it is possible that this is the date of the inscription.” (Wikipedia)

The Zodiac Map star chart. Internet image, public domain.

On the other hand there are investigators who believe in it’s authenticity. Carl Lerhburger (2015) cites Allen Deal (1984) in his chapter on Hidden Mountain. Deal referred to a petroglyph panel that he concluded is a “zodiac map.” “Referred to as the ‘zodiac map,’ it is a flat horizontal rock with petroglyphs that seem to record the constellations in the sky when a solar eclipse occured in 107 B.C. - - - According to Deal, each of the pecked rock art images represents constellations specific to Semitic cultures, which would rule out their being made by native peoples. - - - In short, by overlaying a modern computer-generated sky chart as seen in New Mexico on September 15, 107 B.C., onto the Hidden Mountain star chart petroglyphs, Deal demonstrated a connection that fits with the dating of the epigraphy on the inscription and supports the idea that the Los Lunas Decalogue Stone is an approximately two-thousand year old Hebrew inscription.” (Lehrburger 2015:290) While Lerhburger does not specify the distance and relationship between the inscriptions, or give any other indication as to relative weathering, or apparent style, he does seem convinced that they relate directly to each other and that the “zodiac map” proves the authenticity of the Decalogue inscription.

And finally, Daniel de Caussin claims that there is a Mediterranean terebinth tree from the Holy Land growing over this rock. “The tree above this rock is a Terebinth tree. In this area there are five of these trees and these trees are not native to North America. The scriptures talk of the Terebinth trees and the Hebrews are compared to this tree.” (Academia:2) I have seen no claims in other sources of these trees from the Holy Land being anywhere around the rock, and as I said I have not visited the site so I cannot commit to any personal knowledge of this.

While I do think a fairly strong case can be made for some prehistoric visitation to the Americas from Europe, the Mediterranean, etc., I have not yet seen any examples of so-called epigraphic inscriptions that convince me that they were actually carved by prehistoric visitors from the Old World. Additionally, I am convinced that any indications of these early visitors would be much more likely to be found near the coast, not the middle of the continent.  But regardless of my own beliefs and opinions on the subject I do feel that these inquiries have a valid place in the field of rock art studies. Let us never become closed-minded and hostile to input from many sources, even if we do not agree with it. These inputs help keep the study of rock art so fascinating.

CLAVIFORM, VENUS OR STEATOPYGIA?

Equine, Image from Hussein et al., 2025, Figure 5, page 20, (Image sharpened with chatGPT).

A recent study of a rock shelter with considerable rock art, found in the central Sinai Peninsula of Egypt has been released. Al-Zolma rock shelter is decorated with a profusion of petroglyphs, including anthropomorphs of considerable interest.

Gazelle, Image from Hussein et al., 2025, Figure 6, page 20, (Image sharpened with chatGPT).

“The study of the twelve panels identified 366 individual petroglyphs, including 146 animal figures, 112 human figures, 16 unknown scratches, and 92 indeterminate forms. These petroglyphs encompass several types of images, such as Bovids, Equids, Antelopes, Camels, Gazelles, Ostriches, Ibex, Felines (Lions and Leopards), and headless women. Most of Al-Zolma Rockshelter’s engravings are depicted in a naturalistic style, with variations in quality and size among subjects.” (Hussein 2025)The variations in quality and size suggest that the images were created by different people across an unknown span of time.

Bovid (auroch?), Image from Hussein et al., 2025, Figure 8, page 20, (Image sharpened with chatGPT).

“The execution style techniques appear to have evolved over time. Some engravings were done by incision, where the outline of the subjects is made with shallower grooves. Others exhibit a more developed technique, appearing as raised relief.” (Hussein 2025) The reported differences in technique seem to rely on how deeply the outlines and details of the figures are carved, although some are essentially carved deep enough to qualify as relief carvings.

A particular surprise at this site was a series of headless female figures. “One of the prominent petroglyph examples from Al-Zolma Rockshelter is the depiction of headless women, totaling 112 figures, each displaying different styles and engraving techniques. These figures typically represent the torso of a female figure de picted in profile, featuring prominent breasts and buttocks, yet lacking both the head and lower limbs in several instances.”  (Hussein 2025)

Female, Image from Hussein et al., 2025, Figure 7D, page 21, (Image sharpened with chatGPT).

“Interestingly, the majority of these figures face left, with only three facing right. They vary in height from 10.87 cm to 32.65 cm, and are often superimposed by images of bovids, antelope, camels, and equids. The execution techniques range from scratches and incised lines to what appears to be raised relief. Similar examples of headless women have been found at other sites in Egypt, such as Qurta (QI-QII) and el-Hosh ATB11. Moreover, the significance of these ‘Headless Women’ figures extends beyond Al-Zolma Rockshelter, and other Egyptian sites bearing resemblance to depictions found across the European Magdalenian world, both in rock art and as statuettes made of various types of stone.” (Hussein 2025) The reference to headless women ‘found across the European Magdalenian world’ refers to claviforms and/or the so-called ‘Venus’ figures of the European Paleolithic. These were small figurines carved from stone or from mammoth ivory.

So, were the artists of Al-Zolma rock shelter influenced by European claviforms, ‘Venus’ figures, or something else? In other words. is this evidence of cultural contact between the Sinai and Paleolithic Europe? Another possible interpretation might be considered. The females of Khoisan and related tribes of Africa often display steatopygia, a condition where extensive fat deposits accumulate on the buttocks and thighs. It can be found randomly pretty much worldwide, but is more common among the ‘Hottentots’, the pre-colonial inhabitants of much of southern Africa. Of course, it is possible that the European ‘Venus’ figures are also meant to depict steatopygia, but that is not the general assumption for their meaning.

No direct dating has been done on the art in Al-Zolma Cave. “Dating the Al-Zolma engravings remains a challenge, but stylistic similarities to established Late Paleolithic sites in Egypt suggest a potential age. Further research, including radiocarbon dating and OSL dating in association with the engravings and a deeper understanding of the surrounding environment and potential archaeological sites in Wadi Al-Zolma, could offer valuable context for interpreting the rock art and provide more precise chronological information.” (Hussein 2025:24)

“”The more I looked at the engravings,” says Hussein,” the more I thought the artworks resembled those you might find in Lascaux Cave or other famous European Paleolithic sites.” Hussein learned that an engraved depiction of an aurochs very similar to the one in Al-Zolma Cave had been made in southern Egypt around 15,000 years ago.’” (Powell 2026) This coincidence helped confirm the age of the Al-Zolma art in his mind leading to the announced Paleolithic age for these petroglyphs.

The authors of the study have concluded that this rock art is potentially Paleolithic in age based upon stylistic similarity to other sites in the Sinai peninsula that have been dated.  “The engravings in Al-Zolma Rock shelter executed in a naturalistic style, similar in appearance to the rock assemblages found at other sites in Upper Egypt, such as Wadi (Chor) Abu Subeira (Wadi (Chor) Abu Subeira, an Eastern Desert Wadi, located 12 km north of Aswan): CAS-1320 and CAS-6,21 as well as to those of Qurta (QI, QII, and QIII),22 and Abu Tanqura Bahari 11 (ATB11) at el-Hosh, both north of Kom Ombo. Studies conducted at these sites have successfully dated rock art to the late Paleolithic period, approximately 16,000-15,000 BP. This provides a strong possibility for attributing the engravings in Al-Zolma Rockshelter to the late Paleolithic period.” (Hussein 2025) So, were these female figures inspired by Paleolithic European claviforms or ‘Venus’ figures, or by steatopygia? Can we ever know? It is, however, certainly a wonderful surprise and a really fun idea to speculate on.

WHO MADE IT? DNA ANALYSIS FROM CAVE PAINTINGS:

Back on 17 August 2024, I wrote a column here on RockArtBlog titled ‘DNA Analysis From Cave Paintings,’ in which I expanded upon the recent news that DNA had been discovered in the sediments of anciently inhabited caves. At that time I wrote “for some time now it has been possible for scientists to extract DNA from the sediments in caves, including human and hominin DNA. This leads me to speculate that perhaps we may also be able to detect DNA from manually applied cave paintings such as positive handprints and get an analysis of the artists themselves. Considering that the human body sheds cells constantly it would seem logical that any paint on a cave wall that was applied by hand might contain detectable DNA in human skin cells shed during the application of that paint. And with the advances in DNA analysis this might be a way to personal data such as skin color, eye color, gender, and other data that would allow us to generate a detailed picture of the artist.” (Faris 2024) This speculation seems completely logical to me. Never  bet against scientific advance.

Now we have a report of a study that attempted to do just that – find DNA in the cave art. The team tested 24 rock art panels and located human DNA in a sample from one panel, admittedly only a partial success, but a step in the right direction. “With ancient human DNA obtained from only one of 24 rock art panels sampled, despite generally favorable preservation conditions at many rock art sites, our findings suggest that pigmented surfaces themselves rarely retain enough DNA to remain detectable after thousands of years. The absence of ancient DNA in the Altamira airbrush further supports this notion.We also detected no faunal or other non-human DNA that could be clearly linked to the use of organic binders. Nevertheless, given the diversity of rock art techniques and contexts, it remains possible that rock art from other sites, periods, or styles could more consistently yield ancient DNA. For example, it would be desirable to test DNA preservation in additional samples from figurative rock art, or in hand stencils from sites with better DNA preservation than Maltravieso. As demonstrated here, systematic sampling of both the artwork and adjacent surfaces, along with sensitive methods for faunal DNA detection, should be incorporated into future research to help distinguish DNA related to art production from that introduced by other processes. It should also be investigated whether DNA extraction protocols can be improved specifically for cave wall surfaces.” (Mesa et al. 2026:7) This is really just the beginning of the process.

When you remember how many scientific advances begin as failures – how many tests did Edison have to make before he found a usable light bulb filament? “Despite favorable conditions for ancient DNA preservation at many sites, ancient DNA was detected in only one of the 24 rock art panels examined, and two additional locations adjacent fo other rock art panels. This rarity suggests that pigment surfaces rarely retain enough DNA to survive for thousands of years, particularly if they are not protected by mineral crusts or sealed environments. ‘The preservation of human KNA on cave walls is highly variable’, says Bossoms Mesa. ‘But when it does survive, it tells a powerful story. And while these first results are promising, I think our priority now should be to refine the methods and to understand under what conditions we can expect a higher success rate’.” (Max-Planck-Gesellshaft) And, as these conditions are learned future studies can focus on sites with a higher chance of success.

Matthias Meyer, a member of the team that did this study, expresses optimism about the potential of such a project. “’This is just the beginning’, adds Meyer. ‘We now know that cave walls are genetic archlves of past human presence. The next step is to test more sites, art styles and techniques, especially hand stencils and figurative art in caves with good molecular preservation, as far as minimally invasive sampling allows’. With further work, it may become possible to reveal the makers of at least some pieces of cave art – and to put faces, or at least genetic identities, to the artists who created them.” (Max-Planck-Gesellschaft) As the ability to detect and analyze DNA improves we can expect result to get better as well.

Heretofore DNA studies and analysis seem to have developed following to Moore’s law. Originally postulated in regards to integrated circuits, Moore’s law stated that the number of transistors in an integrated circuit doubles every two years. Admittedly it is a stretch to apply that to DNA studies in rock art, but look at the development of DNA analysis in the short time since its beginnings. This may not be too far from the truth. And, I would still like to know the color of the eyes of the artist who painted Lascaux, and I think it is coming.
