WHAT DO FOOTPRINTS MEAN?

 

Footprints (Podomorphs) in Sweden. Image from Fahlander, 2026, Figure 3A.

RockArtBlog has had a number of columns about footprints in rock art over the years (click on footprint in the cloud index at the bottom of the blog). Various sources have speculated that they are meant to symbolize travel, personal identity (like a signature) or even a sort of ‘Kilroy was here’ mark. Now, a new possible meaning has been proposed by Fredrik Fahlander (2026) in a recent publication, the footprints might represent a contract.

Fahlender uses a term for footprints, podomorph, which is somewhat obscure, although I suppose we can consider it accurate. “During the Bronze Age, a particular type of podomorphic petroglyph was produced on the outcrops by the sea in southern Scandinavia, in the Mälaren region of central-eastern Sweden. The study shows that the petroglyphs are organized in relation to water as well as to different minerals visible in the rock. This pattern indicates that they are not simply images or symbols but also physical ‘devices’, produced to do something. One purpose was for the frequent single podomorphs to be paired with another at a later stage. Because podomorphs in a pair generally are of different sizes and form, it is suggested that each one belongs to an individual of different age and/or sex– potentially depicted in stone to show existing or desired future relations, agreements, pacts, friendship, marriages etc.” (Fahlander 2026:1) Fahlander’s paper studies Bronze Age footprints and he points out a very interesting, and diagnostic, fact. In many pairs of footprints the left foot and the right foot are created with differences in style and/or technique, suggesting that they were created by different people and perhaps at different times.

Breaking down footprints in detail Fahlander discusses their styles and the techniques used to create them. “Traditionally, Bronze Age rock art has mainly been discussed from a representational perspective as images or symbols: as is particularly evident in the manner of documentation in which the motifs are rendered as two-dimensional black figures on a white background. This despite the numerous examples reported of how petroglyphs integrate and interact with the microtopography of the rock The representational focus also entails problems of categorization, where different types of motifs of diverse techniques, contexts and potential functions are amalgamated into one single category.” (Fahlander 2026:2) He is looking at the petroglyphs much more closely than just how they relate to the landscape or environment.

 There have long been theories of relationships between rock art and features in the rock like cracks. But, Fahlander seems to take it down almost to a microscopic level in significance. “In recent years, however, research has put more emphasis on aspects of production and how petroglyphs relate to waterflows, fissures and mineral veins in the outcrops. This expanded perspective partially bridges the nature-culture divide and stresses the physicality of the Bronze Age petroglyphs as a type of visual and physical ‘device’ rather than being mere images or symbols.” (Fahlander 2026:2) One potential problem with this, however, is that we may not have much, or accurate, knowledge of waterflow, fissures and mineral veins when the rock art was created. So this assumes that the surface of the rock has not changed since the footprint was placed there.

In Scandinavia, Bronze Age podomorphs are produced in various types and can be either fully hollowed out, resembling actual footprints or outlining the shape of a foot sole or a print. Both types can have one or more crossing lines commonly assumed to represent straps to fix the leather sole. Pairs also occur as being merged, sharing a common groove. It is important to note that both types of clad podomorphs are designed to look like real footprints. Several preserved fragments of footwear with and without lacings have been found in Bronze Age oak-coffin burials of both sexes. A real Bronze Age footprint in snow, clay or sand would thus leave either a crossing line like in many of the contour-lined podomorphsor just the plain oval shape of the leather sole.The chronology of the different types is complex. Although the majority of South Scandinavian rock art can be firmly dated to the Bronze Age period, some petroglyphs might be slightly earlier and a few may be of later Iron Age date. The podomorphs stand out from the other motifs since many researchers attribute the majority to the late Bronze Age andpre-Roman Iron Age.” (Fahlander 2026:3) This observation interests me the most in his paper. That the footprints in a pair may not match up. Fahlander’s reasoning here is fascinating.

“One interesting aspect of the Bronze Age podomorphs is that, in contrast to the animal tracks of the Neolithic rock art tradition of northern Fennoscandia, podomorphs only rarely seem to indicate movement . The Järrestad and the Rickeby sites have four naked and six clad podomorphs in succession, respectively. At first glance, they seem to indicate movement, until you realise that they consist of right feet only. At the Tisselskog site in Dalsland is another example of ten podomorphs with toes that seem to take steps down the outcrop. Judging by the toes and arch of the foot, all of them are also right feet. This could suggest an attempt to illustrate movement by jumping on one foot, but it is more likely to be the result of other considerations. At Rickeby, for example, it is striking that the ‘trail’ is actually a series of podomorphs produced within a natural depression in the rock, which is regularly flooded after rain.” (Fahlander 2026: 5-6) These observations, of course, may only be true for Bronze Age footprints (podomorphs) in northern Fennoscandia. Studies elsewhere should show us where else such conclusions can be applied

“Different interpretations of their meaning and functions. Most common is the idea that they represent actual persons. As such, the imprints are argued to be produced in connection with initiation rites, marking presence or remembrance. Another common theme concerns symbolic representation. Almgren, for example, suggested that podomorphs symbolize the tracks of an elusive deity that cannot be depicted. A third connection is made between podomorphs and death.” (Fahlander 2026: 7)

 Bradley (1999) proposes that podomorphssymbolize the transition between aquatic (realm of death) and land (realm of the living) by leading from the burial mounds on the hillocks down to the sea. Later, Goldhahn (2012) explores a similar connection, emphasizing a relation between podomorphs and graves. Among his examples are Törnsfall 107, a cairn that partly covers a series of podomorphs on the rock beneath, and a block with a pair of podomorphs found adjacent to a cairn in Norway (Simonsen and Vogt 2005). Even though all these interpretations have their merits, none is sufficiently supported by the wider bodyofrockart. The idea of an invisible deity does not resonate well with the abundant single and pairs of podomorphs at some sites. The association of movement of either the sun or the dead lacks footing in the rock art itself, as the podomorphs are static and irregularly oriented in different and opposite directions. The idea that footprints represent real people is somewhat contradicted by the sometimes impossible sizes. In general the sizes are quite small. If taken at face value, the great majority would represent children’s footprints with only a small number belonging to adults. (Fahlander 2026: 7)

      
Footprints interacting with the microtopography of the rock. Image from Fahlander, 2026, Figure 6C.

So the first step is a careful examination of the petroglyphs to decide how closely they might match. “A first question to discuss is whether the visual qualities of the pecked podomorphs refer to shoes, feet or prints. The distinction is important because tracks and feet tend to be considered quite differently in terms of their powers and purposes. The survey of the Mälaren podomorphs shows no indications that any podomorphs are feet viewed from above. On the contrary, the naked feet with toes and the fully hammered-out types both qualify as prints that could have been outlined after a wet footprint on the rock. The contour-lined types are less evident, but the ones with cross-straps are also most likely to represent prints. This attention to detail and the fact that someone took the extra time to peck a crossing groove to make them look like a real print from a shoe with straps must thus be regarded as important. A second significant question is whether podomorphs are general ideograms or prints of particular individuals. The variable sizes of the podomorphs might allow them to be interpreted as particular prints. Taking their lengths at face value would mean that the majority (i.e. 18–25 cm) are imprints of 7–10-year-olds. However, it would not explain the impossible sizes in the lower and uppermost registers (Table 3). Moreover, as many podomorphs are often found on irregular boulders and on rather steep outcrops, where it is difficult for a person to stand, not all (if any) podomorphs are likely to emanate from actual footprints. Thus, we should not expect podomorphs to be exact facsimiles of someone’s print, nor to represent or relate to particular individuals.” (Fahlander 2026:12-13) Now, if we can determine that the individual footprints are not identical this opens up a whole new range of possibilities.

And at this point Fahlander puts it all together with his creative possibility. “Another option that better fits the organization and articulation of the podomorphs relies on the fact that they are produced both as singles and in pairs. That the podomorphs of the majority of pairs - are of different lengths and shapes is probably not a coincidence. This opens up a scenario where the examples of a single podomorph might be the first step in making a pair. A ‘material invitation’ to add another. A case supporting such a notion can be seen in at Boglösa 138, where one of a pair of is only partly hammered out, indicating a process divided into sequential stages transforming one type into another (Fig. 8a). Such a prolonged ritual could potentially involve a quid pro quo scenario where a second podomorph was added after a request or wish has been fulfilled. This would, however, not explain the joined pairs, which most likely were produced in one event. But if each podomorph of a pair ‘belonged’ to different individuals, particularly if of a different age and/or sex, it would make sense of the diverging designs of paired podomorphs (e.g. different sizes and forms, number of straps and contrary orientation, see Fig. 5). Considering the permanence of the petroglyphs, podomorphs might have been employed as a ritualized (or ontological) way of creating a lasting bond between persons: for example, to demonstrate materially friendship, agreements, pacts or marriage etc.” (Fahlender 2026:15) So there we have it. If a footprint represents and individual, then a pair of footprints differing in detail could represent two different individuals, in other words a relationship – a contract. A very intriguing proposition and some very original thinking.

THE MARTIN BOWDIN GALLERY IN THE PURGATORY REVISITED:

Bear and fox, Bowden Trail, Picketwire Canyon, Colorado. Eldon Brown photograph from John and Daphne Rudolph.

Back in August and September of 2015 I did a column in two parts about paintings produced by a gentleman named Martin Bowden on the cliffs of the Purgatoire (Picketwire) Canyon in southeastern Colorado. Some time later I was contacted by a wonderful lady named Alanna Blu who had become enthusiastic about Bowden’s art and wished to work to preserve it. Her efforts have since borne considerable fruit and I wish to celebrate her work and results here in RockArtBlog.

Instead of trying to describe a project that I can take very little credit for I will let Alanna describe it in her own words. "What began as a small grassroots effort to reconstruct Martin Bowden's history has steadily expanded into a much larger preservation and documentation enitiative. The mayor of Trinidad has publicly embraced the importance of Bowden's legacy, KOAA5 out of Colorado Springs recently filmed a public-innterest feature on the project, and multiple archaeological and preservation groups have now reached out independently after following the work online" (BLu 2026) My original columns on Bowden included over a dozen pictures of his work. Alanna has noww amassed considerably more material, peserved and made available to the public.

Blu has also been working to share her knowledge of these unique works of rock art. "Most recently, I was invited to give a presentation for an archaeological society, and SPACES (Saving and Preserving Arts and Cultural Environments), the international organization dedicated to visionary environments and outsider art sites, has also contacted me about the project. The conversation around Bowden is shifting from 'local curiosity' into a broader discussion about whether Colorado contains a historically significant outsider folk art environment that deserves long-term documentation and preservation attention. Through all of this, I've continued emphasizing that this effort is fundamentally about documentation, historical reconstruction, and preserving memory - especially as th canyon artwork continues to deteriorate with time." (Blu 2026)

She approached this project with a concern to preserve the works and Bowdin’s memory. “Through all of this, I’ve continued emphasizing that this effort is fundamentally about documentation, historical reconstruction, and preserving memory — especially as the canyon artwork continues to deteriorate with time.” Through all of this, I’ve continued emphasizing that this effort is fundamentally about documentation, historical reconstruction, and preserving memory — especially as the canyon artwork continues to deteriorate with time.” (Blu 2026) I could not have said this any better myself. As a student of rock art our goal has to be, as Alanna said, “documentation, historical reconstruction, and preserving memory.”

She has expressed her gratitude to the community for their participation and coming forward with pictures and stories. Those were very valuable when she was putting together pieces of the history of Martin and his life in the canyon. (Blu 2026)

Blu's hard work has resulted in an impressive suite of references on Bowden's creations including the following Wikipedia and Facebook pages. 

https://en.wikipedia.org/wiki/Martin_Bowden

In Facebook search for ‘Martin Bowden and the Painted Canyon.’

She has also registered a Colorado non-profit foundation and is working on a nomination for the National Register of Historic Sites.

It is personally very gratifying to have had a small part in the inspiration for all of this hard work and enthusiasm. I also wish to give credit to John and Daphne Rudolph for the photographs by Eldon Brown of Bowden's paintings that I used. It also gives me great pleasure to know that the future of Martin Bowden's work is in such good hands. Alanna, good work, and thank you.

GIRAFFES IN ROCK ART:


Giraffe. Image from Animal Conservation Awareness.

Giraffes, Niger. Internet image, public domain.

One theme in rock art consists of animal portrayals, records of the life in and around the artist’s environment. And, some animals are just more interesting than others. For one reason or another something about them feels improbable, or at least extreme, and that can fascinate us. For me this would include giraffes, the improbably long-necked animal of Africa.




Giraffe, Tanzania. Image from Ritchie, page 102.

Giraffes, as a theme in rock art, are mostly found in various parts of Africa from the South Cape to the Mediterranean because that is where they exist in life. Much of the fascination with giraffes is caused by their improbable build and life. Although they appear to be ungainly, lions seldom manage to take down a fully grown giraffe. They can run deceptively fast and have a deadly kick.

In southern and South Africa some San groups regard the giraffe as a ritual animal possessing supernatural potency (often called n/um by Kalahari San peoples). This spiritual force is associated with healing, trance, and access to the spirit world. During healing dances, shamans enter altered states of consciousness. A traditional "Giraffe Medicine Song" has been recorded among Kalahari San communities and is used to help healers enter trance and travel spiritually.

Giraffes appear with frequency in San rock paintings. Many researchers interpret these paintings not simply as hunting scenes but as depictions of spiritual experiences, trance visions, or animals associated with supernatural power. San cosmology is broadly animistic. Animals are not merely game; they are persons or beings with spiritual significance. Giraffes, along with kudu, elephants, and other animals, can appear as guides, powerful beings, or participants in the spirit world. The importance of this role may explain the frequency of their appearance on the rocks.

Matopos, Zimbabwe. Zimmbabwe Ministry of Culture. Image from Ritchie, page 31.

In Zimbabwe “a study of the morphological and behavioral attributes of the giraffe can be central to the understanding of San rock art even though such studies have  to be supported by different theoretical frameworks.” (Muringaniza and Manyanga 2017:11-12) The truly large number of San giraffe portrayals attests to their importance to the culture of these people.

Leaving southern Africa and heading northward toward sub-Saharan Africa we find more giraffe imagery, the most impressive of which is found at Dabous, in Niger. “The Dabous Giraffes are Neolithic petroglyphs by unknown artists on the western side of the Air Mountains in north-cantral Niger. The carvings are 6 meters (20 ft) in height and consist of two giraffes carved into the Dabous Rock with a great amount of detail. One of the giraffes is male, while the other, smaller, is female. The Dabous Giraffes are located on a sandstone outcrop in the Tenere desert in the first foothills of the Air Mountains, about 110 km north of Agadez and a few kilometers from the Trans-Saharan Highway. They are the largest known animal petroglyphs in the world.” (Wikipedia) This last sentence may be questioned given the claim of a gigantic snake petroglyphs found in South America.

Dabous giraffes, Niger. Internet image, public domain.

This location possesses a considerable store of rock art. “In the surroundings, 828 images have been found engraved on the rocks, of which 704 are animals (cattle, giraffes, ostriches, antelopes, lions, rhinoceros, and camels), 61 are human, and 17 are inscriptions in Tifinagh. The carvings are believed to have been done between 6,000 and 8,000 years ago, during the African humid period, when the region was less arid, and the Sahara was a vast savannah.” (Wikipedia) During this period the Sahara desert was a well-watered grassland and we may assume that giraffes were common there at that time.

“The two life-size giraffe petroglyphs, known as the Dabous giraffe, are the largest known animal carvings in the world. These tall and graceful animals were perceived by a paleolithic society as especially impressive: chimeric figures, with the face of a camel and the spots of a leopard, markings that had been portrayed with such attention to detail in the carvings; animals with a speed and ferociousness in self-defence that belied their unhurried gait? There is no other animal like a giraffe. Or perhaps their unique attribute resided in their unusually large eyes which may have attracted the attention of ancient cultures. The giraffes’ ability to see great distances, beyond scent or sound, would not have gone unnoticed, and may have become a metaphor for foresight and prediction.” (Bradshaw Foundation) ‘May’ and ‘perhaps’ indicate guesswork here, but their unique appearance certainly attracts attention and one would expect would have led to a position of importance in the cosmology of the people. Needless to say, if giraffes had lived in North America there would be a whole lot of giraffe petroglyphs and pictographs here as well.

THYLACINE AND TASMANIAN DEVIL PAINTINGS IN NORTHERN AUSTRALIA:

Sarcophilus harrisii (Tasmanian devil). Image from Wikipedia.

Most of us probably know of the Tasmanian Devil as the Looney Tunes cartoon character who appeared in 1954. Disappearing in 1964, he reappeared in the 1990s and again became popular. (Wikipedia) The thylacine (Tasmanian tiger) may be the most popular target of cryptozoologists trying to prove rather or not they are completely extinct. It is also one of the most mentioned targets for the biological concept of de-extinction, recreating an extinct animal by using DNA from museum collections. Tasmanian devils are not yet extinct on the island of Tasmania, but are threatened by their bizarre cancerous facial tumors that affect most of the population.

Thylacines, Injalak Hill, Northern Territory, Australia. Image from Craig Banggar.

Paul Tacon wrote a concise history of the discovery and early classification of these creatures. “The Tasmanian devil (Sarcophilus harrisii) and the Tasmanian tiger (Thylacinus cynocephalus), also known as thylacine, were first described scientifically in 1808 by George Prideaux Harris, the then Deputy Surveyor of Van Diemen’s Land. ‘the species was originally given the scientific name Didelphis cynocephali (dog-headed opossum), alongside the Tasmanian devil (Didelphis ursine) or bear opossum’ by Harris. Later in the 1800s, there were various taxonomic name changes to both species, resulting in the current classifications and the Tasmanian devil being named after Harris. To date, few skeletal remains of devils or thylacines have been found in Arnhem Land (Northern Territory, Australia), but part of a Tasmanian devil mandible was recovered from an excavation at the Padypadiy rock shelter), the East Alligator River in a deposit dated to 3120 ± 100 BP. Nearby, at the Madjedbebe rock shelter – recovered a thylacine maxillary fragment painted with red ocher dated to ‘2.7 – 3.9 calibrated kyr BP’.” (Tacon et al. 2026) So, when Europeans reached Australia, these animals were both extinct on the mainland, but remembered in the myths and legends of the aborigines.

Rock art depictions suggest thylacines were more widespread and more culturally important across mainland Australia than Tasmanian devils as only 25 Tasmanian devil images have been documented, including the two described above, versus over 160 thylacine depictions. Thylacines may also have survived much longer in pockets of western Arnhem Land, the Kimberley and elsewhere than Tasmanian devils after the arrival of the dingo. (Tacon et al. 2026)

Western Arnhem Land has the most detailed oral history about thylacines from anywhere in Australia and stories about the creature continue to be told by some people today. In western Arnhem Land oral history thylacines are associated with Rainbow Serpents and often are described as the Rainbow Serpent's pets or dogs, sometimes in pairs and swimming. Three of the Awunbarna sites discussed above have pairs of thylacines and we have documented 29 paintings of Rainbow Serpents at Awunbarna. One of the Awunbarna Rainbow Serpents, less than 1000 years of age given the style and preservation, has three small thylacine-like creatures painted over part of its tail that are fresh-looking and do not appear to be very old. (Tacon et al. 2026) As to this last example we must remember that Australian First Nations tradition includes individuals who are responsible for pictograph sites and are supposed to refresh or repaint them whenever they need it.

Awnbarna Maliwawa style Thylacines next to Malinwawa human figures. DStretch (ids). Image by Joakim Goldhahn, from Tacon et al, Fig. 8.

Indigenous peoples also told stories of how thylacines hunted kangaroos. Contemporary western Arnhem Land artists are inspired by these and related stories as well as rock art depictions, so that occasionally paintings of thylacines are made on bark, paper and canvas. But contemporary paintings of Tasmanian devils or other extinct animals are not made despite lots of mythological creatures with animal, human-animal or human-like forms made by western Arnhem Land artists today and in the past 100 years. (Tacon et al. 2026) Many more illustrations are in the 2026 report by Tacon et al, listed below.

As I said above, thylacines, along with mammoths, are perhaps the most popular targets for de-extinction using DNA from museum specimens. On the island of Tasmania cryptozoologists are still searching for specimens of the Tasmanian tiger, and some claim they have seen it but no solid proof has been presented. It is, however, a fascinating subject and I wish them all luck.

BLOMBOS OCHER CROSSHATCHING, A NEW SUGGESTION OF PURPOSE:

Engraved ocher, Blombos Cave, South Africa. Image from Don Hitchcock, donsmaps.com.

A few years back (2018) I did a column about the engraved ocher fragments from Blombos Cave (see references below). The column was ostensibly about these markings being, at that time, considered possibly the oldest petroglyphs known, but in it I suggested that possibly the grooves were to improve the grip like the checkering on a rifle stock. Sylvia Stein (2025, 2026) has proposed that the engraving on the piece of ocher is actually a picture of a fishnet.

Pierced shell beads, Blombos Cave, South Africa. Internet image, public domain.

“The invention of string, thus, is the essential tool in the fishing net with shell weights (100,000 kya to 74,000 kya), preceding the invention of the bow and arrow (60,000 kya).The use-wear studies of the punctured Blombos Nassarius shells have clearly established that the shells were strung either loosely or knotted, perhaps for quick horizontally stringed shells replacement on nets for mass fishing, before the invention of the bow and arrow hunting a single prey. Thus, essential, is that use-wear studies indicate that the dull Nassarius perforated shells were strung not in a curve or loop for functions as a bracelet, or necklace, though horizontally as a string of shell weights to be affixed to the bottom of a fishing net. Our argument then heavily relies on these use-wear studies of shells horizontally on a string, essential to making fishing nets, preceding bow and arrow in brain evolution.” (Stein and Pacheco 2025:33) So, in this thesis the pierced shells found in Blombos Cave are not for ornamental use as in a necklace or a bracelet, but are pierced to be tied on to the bottom of the net as net weights.

Stein, Chukhman and Makhin (2026) revisit that thesis with complicated analysis and statistical studies. In the end their conclusion is that “the implications are the occupants of the MSA BBC not only had intellectual capacities to design, record, make and re-use string based nets, they had developed superior finger dexterity with refined engineering net construction capacities.” Possible, but what would statistics have to do with this question.

Stein's fishnet reproduction. Image by Sylvia Stein, ResearchGate.

Now, I suppose that this could represent the design of a fishnet, however, if I was diagramming a fishnet I believe I would have done it in larger scale – feet instead of inches. Additionally, I do not see any representations of weights at the bottom junctions of the supposed net engraving.

An online page at 'Wikipedia-Nassarius' discusses "several 75,000-year-old Nassarius kraussianus beads which were found at Blombos Cave, South Africa (including some colored with red ocher). These beads have previously been thought to be the oldest examples of jewelry." (Wikipedia) The jewelry theory has certainly been the most common interpretation of these pierced shells for quite some time.

Nassarius shells come from a species of marine snail and have a coiled shell like other snails. It seems inevitable with the coiled structure of a snail shell some air will be trapped inside when thrown into the water, thus possibly causing it to float which would not make a great net weight. Now I certainly cannot say for certain, but I must go with being a skeptic on the Stein, Chukhman and Mahkin’s theory.

But, back to the ocher itself – checkering for a better grip, or just decoration seem to be the most satisfying conclusion.

In the ever proceeding scramble to identify the earliest, or oldest, rock art, we have another claim, this time from Europe. In the category of finger marks may I have the envelope please? And our winner is - - finger fluting on the cave walls of La Roche-Cotard left there by Neanderthals.

“The oldest known engravings in Europe, discovered in a French cave sealed up for tens of thousands of years, likely weren’t crafted by modern humans but rather Neanderthals, a new study finds. Within the cave of La Roche-Cotard 150 miles (240 kilometers) southwest of Paris, the researchers analyzed a series of non-figurative markings thought to be made by ancient human fingers, according to a study published – in the journal PLOS One. The cave had been sealed up by sediments until the late 19th century. Modern excavations at the site have yielded numerous stone tools whose style is associated with the Neanderthals, suggesting that they created the art.” (Killgrove 2023) In addition to the style of stone tools the investigators used hard dating to infer the age of the marks.

The finger marks themselves were not dated, but optical stimulated luminescence dating told the investigators when the cave became inaccessible due to sedimentation. “OSL dating indicates that the sediment deposition closed the cave > 51 ka (95% confidence) ago, or at 57 ± 3 ka (68% confidence interval). This age makes access to the cave interior by anatomically modern humans (AMH) highly unlikely, as we believe that evidence for their arrival in Western Europe prior to 45 ka - is not yet demonstrated. The non-figurative engraved marks at La Roche-Cotard are necessarily older than 57 ± 3 ka, and can be, therefore, confidently stated to be of Neanderthal origin.” (Marquet, Jean-Claude et al., 2023) This adds even more proof of the cognitive sophistication of our hominin relatives.

While the term ‘graphic productions’ may be a little overly optimistic for the collections of markings left on the cave wall, they marks were made intentionally and apparently by hominins, not cave bears or other fauna.“The graphic productions identified on the walls of La Roche-Cotard demonstrate a deliberate creative process visible in the spatial arrangement of the engraved marks on the cave wall. This is perhaps one of the most remarkable aspects evidenced by the creative ensemble at La Roche-Cotard. As discussed above, there is little graphic evidence associated with Neanderthals, and that is mainly on mobile objects (pebbles, slabs, bones…), rather than walls. In contrast, the walls of La Roche-Cotard testify to something different: the frequent repetition of thoughtful gestures, organized in space both on the wall surfaces and with respect to the cave as a whole.” (Marquet, Jean-Claude et al., 2023) I cannot go quite as far as Marquet’s last sentence in describing the marks, but I applaud his enthusiasm.

Now, of course, we have to address the question of whether finger-fluting is art and deserves to be lumped in with rock art. In the case of RockArtBlog I say yes. It is intentional modification to the cave wall in the same way that a magnificent painted animal on a cave wall is and that is the definition I am using.

ANOTHER CLAIM OF PALEOLITHIC WRITING:

A recent paper by Christian Bentz and Ewa Dutkiewicz of the Saarland University in Saarbruken, Germany investigated deeply the human applied marks on Paleolithic carved bone and stone to attempt to gain deeper understanding toward their possible significance. “First, our analyses illustrate that these sign sequences are clearly distinguishable from modern day writing. Second, however, their statistical properties are comparable to sign sequences on the earliest protocuneiform tablets. Third, Paleolithic signs were systematically applied to yield higher information density on certain types of objects, e.g. ivory figurines compared to tools.” (Bentz and Dutkiewicz 2026:1) We need to carefully distinguish between what these authors claim and what the headline editors of reports on it have stated. Bentz and Dutkiewicz have not claimed that these marks constitute a form of writing. “However, they prove that the first hunter-gatherers arriving in Europe already applied sign sequences of comparable complexity in a deliberate, systematic, and conventional manner—several ten thousand years before the advent of genuine writing.” (Bentz and Dutkiewicz 2026:1) News outlets and others who have referred to their paper have, unfortunately, tended to use the word ‘writing’ in their descriptions.

To set the scene - “At the beginning of the Upper Paleolithic around 45,000 calibrated years before present (cal BP), modern humans arrived in Eastern and Central Europe. On their journey they encountered their distant relatives—Neanderthals. In this time of migrations and population turn-overs, modern humans produced a panoply of so-called mobile objects, such as tools and figurines made of ivory, bone, or antler. These are present right from the earliest period of the Upper Paleolithic, the so-called Aurignacian technocomplex. Especially the Dordogne region in southwestern France, the cave systems of the Swabian Jura in southwestern Germany, and a cluster of sites in Belgium have yielded hundreds of objects adorned with sequences of geometric signs.” (Bentz and Dutkiewicz 2026:1) Many explanations for these signs on the ivory, bone and antler carvings have been proposed. People have tried to make them out to be complicated mathematical or calendrical records. Many of us have suspected that some of them represent tallies.

A press release from Saarland University, where Bentz and Dutkiewicz are both employed states that “More than 40,000 years ago Ice Age humans were carving repeated patterns of dots, lines, and crosses into tools and small ivory figurines. A new computational study of more than 3,000 of these Paleolithic signs reveals that they were not random decorations but structured sequences with measurable  complexity. Surprisingly, their information density rivals that of proto-cuneiform, the earliest known writing system that emerged around 3,000 BCE.” (Saarland University) This part depended on the statistical analysis that goes way beyond my ability, and sometimes past believability.

“the people of the Swabian Aurignacian were among the first modern humans to settle in Central Europe. They inhabited the caves of the Lone and Ach Valleys around 43,000 to 34,000 calibrated years ago. They have left behind a panoply of tools and mobile artwork—testimony to their technical skills, and their rich culture. This includes a collection of several dozen ivory figurines, representing animals occurring in the environment at the time, as well as mystical figures of an imaginary world forever lost to us. A subset of these mobile artifacts carry sequences composed of overall more than 3000 signs intentionally carved into their surfaces.” (Bentz and Dutkiewicz 2026:7)

“Our analyses show that these sequences are clearly statistically distinct from those generated with modern day writing systems to represent spoken languages. However, they have a very similar “statistical fingerprint” as the earliest numeric and numeroideographic protocuneiform tablets stemming from the Uruk V period of 3500 to 3350 BC. Moreover, the Aurignacian sequences were not indiscriminately applied to different objects, rather, ivory figurines carry the sequences of highest information density—independent of material constraints such as volume and preservation.” (Bentz and Dutkiewicz 2026:7)

“The hunter-gatherers of the Swabian Aurignacian have hence developed a sign system with some incipient design features also found in writing, that is, an inventory of different sign types and their linear arrangement, but lacking other design features, e.g. productive combinatoriality of different sign types as well as the rebus principle. It remains hard—or impossible—to prove that Aurignacian sign systems served the same numero-ideographic functions as protocuneiform. Moreover, there is another stark contrast between them: Protocuneiform developed into a full-blown writing system representing the Sumerian language within the subsequent 1,000 y. The sign sequences of the Swabian Aurignacian, on the other hand, were stable in terms of information density—for 10,000 y—and then disappear.” (Bentz and Dutkiewicz 2026:7) But, what sort of information were they recording. One possibility is that they were recording details of the animals that were so important to their lives.

This seems to be very much a descendant of the seminal 1978 article in Scientific American by Denise Schmandt-Besserat. Her breakthrough identified the beginnings of Mesopotamian hieroglyphs as being marks on the clay seals of packages and clay envelopes indicating their contents. “The earliest examples of writing in Mesopotamia may not, as many have assumed, the result of pure invention. Instead they appear to be a novel application late in the fourth millennium B.C. of a recording system that was indigenous to western Asia from early Neolithic times onward. In this view the appearance of writing in Mesopotamia represents a logical step in the evolution of a system of record keeping that originated some 11,000 years ago.” (Schmandt-Besserat 1978:59) One of the pieces of evidence presented by Bentz and Dutkiewiecz of a piece of clay with some indentations in it.

One of the other examples covered in Bentz and Dutkiewiecz is a car ved piece of mammoth ivory called the Ache Tusk. Also known as the so-called ‘Adorant’ it was recovered from Geissenklosterle Cave. “Geissenklosterle is an archaeological site of significance for the central European Upper Paleolithic, located near the town of Blaubeuren in the Swabian Jura in Baden-Wurttemberg, southern Germany. First explored in 1963, the cave contains traces of early prehistoric art from between 43,000 and 30,000 years ago, including some of the oldest known musical instruments and several animal figurines.” (Wikipedia) One side of this artifact has a carved, seemingly anthropomorphic, figure, and the other side has a large number of dots. This has been proposed in the past to be a calendrical inscription.

Many of the carved animals from Geissenklosterle Cave are engraved with patterns of carved diamonds, Xs or Vs. These diamonds, Xs and Vs carved on ivory figurines might well represent hair. Their locations are in the same places that long hair would be found on the animals, as in the lion’s mane, the body of the wooly mammoth and the hairy line down the croup of the horse. This usage would be recording information and thus is totally compatible with the premise of Bentz and Dutkiewicz. Details of winter vs. summer pelage might be important to teaching hunting skills.

Recovered from Vogelherd Cave are carved horses, lions, and unknown animals dating back to ca. 40k years BCE. Anotheer example is a carved ivory mammoth from Vogelherd Cave located in the eastern Swabian Jura of southwestern Germany. Patterns of Xs and diamonds range around its body possibly represented the hair of a wooly mammoth.

All of this is to bring me to my point that the press reports are unfair to Bentz and Dutkiewicz. Every article headline that used the word ‘writing’ led readers to unfound assumptions. Their primary claim was that the marks may have represented data and that is totally true, they do. The data just isn’t written. X marks representing hair on an animal is a record of data, a record of where the animals heavy winter pelage might be found for example. Dots of related marks may represent tallies. While Schmandt-Besserat came up with these concepts first, and somewhat deeper and more insightful analysis, their paper is a reasonable contribution to the literature. I have only one other criticism, they did not cite Schmandt-Besserat in their paper or list her in their references, but this was probably just an oversight.
