Archaeologists discovered a 2,000-year-old rock-carved face at Spain’s Tossal de La Cala castle

Archaeologists have discovered a rock-carved face at Toscal De La Cala, a Roman fort in Benidorm, on the east coast of Spain.

Archaeologists from the University of Alicante discovered a 2,000-year-old rock-carved “inscultura” face with three artistic representations of a human face, a cornucopia, and a phallus during excavations.

The carving was described by University of Alicante professor Jesús Moratalla, head of the excavation, as “a relief of outstanding historical importance”.

The carving measures 57 x 42 centimeters, however, Moratalla and his team believe that this scene is “possibly incomplete” since “the upper right quadrant” being missing.

Historical and Cultural Heritage Councilor Ana Pellicer said that there are no parallel references to engraving and reliefs of similar composition at sites in Rome.

Unknown is the carving’s purpose; it might have been graffiti or served a ritualistic function. Given that the Romans considered the phallus to be the embodiment of masculine generative power and one of the symbols of the safety of the state (sacra Romana), the inclusion of a phallus raises the possibility that it served to offer protection.

Given that many Roman deities connected to the harvest, prosperity, or spiritual abundance are frequently depicted carrying a cornucopia in Roman reliefs and coins, the depiction of a cornucopia or “horn of plenty” raises the possibility that the face could be that of a god or goddess.

In a myth, the cornucopia was created when Heracles (Roman Hercules) wrestled with the river god Achelous and ripped off one of his horns; river gods were sometimes depicted as horned.

Located on a 100-meter-high hill, the Tossal de La Cala site was excavated in the 1940s by Father Belda and in 1965 by Professor M. Tarradell, dating the archaeological remains found between the 2nd and 1st centuries BC.

Archaeological excavations carried out by the University of Alicante (AU) since 2013 reveal that it was a Roman settlement occupied by the armies of Quinto Sertorio during the Sertorian Wars.

The Sertorian Wars was a civil war fought between a group of Roman rebels (Sertorian) and the Roman government. (80 to 72 BC)

A 5,400-year-old tomb discovered in Spain perfectly captures the summer solstice

Archaeologists have discovered a 5,400-year-old megalithic tomb near a prominent lone mountain in southern Spain, suggesting the peak may have been meaningful to prehistoric people there.

The area, in the countryside near the city of Antequera, is renowned for its megaliths — prehistoric monuments made from large stones — and the newly found tomb seems to solve one of the mysteries of their alignment.

The tomb was designed to funnel light from the rising midsummer sun into a chamber deep within — much like the contemporary megalithic tomb built more than 1,000 miles (1,600 kilometers) away at Newgrange in Ireland, suggesting both places shared similar beliefs about the afterlife more than 5,000 years ago.

“Newgrange is much bigger and more complex than the tomb we have discovered [in Spain], but they have something in common — the interest of the builders to use sunlight at a specific time of the year, to produce a symbolic — possibly magic — effect,” Leonardo García Sanjuán, an archaeologist at the University of Seville, told Live Science. 

The bedrock at the site is tilted away from the position of the sunrise on the solstice at midsummer, so the builders deliberately constructed a cavity to admit its light, according to a study by García Sanjuán and his colleagues published April 14 in the journal Antiquity.

“They worked very cleverly to make an arrangement of stones, which were engraved and possibly painted,” he said. “These were sacred things placed so that the sunrise on the [summer] solstice would go straight into the back of the chamber.”

Megalithic tomb

The new study describes excavations by García Sanjuán and his team beside a prominent limestone mountain known as La Peña de los Enamorados — the Rock of the Lovers — named after a  legend that says two star-crossed lovers once killed themselves by jumping off it.

The mountain is also famous because it looks like the profile of the head of a sleeping giant, especially at times of low light such as sunrise and sunset.

García Sanjuán and his colleagues excavated the tomb in late 2020 in the “neck” region of the mountain, near the Matacabras rock shelter, which is adorned with pictographs thought to be painted about 5,800 years ago.

They think the tomb was first built a few hundred years after the rock paintings were made, and that it was used for burials for more than 1,000 years.

The archaeologists have found several deposits of human remains in the newfound tomb, dating from three major phases of its use, as well as pieces of pottery.

Ancient landscape

The Antequera area is famed for its natural rock formations like La Peña and the megalithic monuments in the region, which may have been influenced by the local geography. The most famous is the Dolmen of Menga — one of the largest and oldest megalithic structures in Europe, which was built between 3800 B.C. and 3600 B.C. 

But the passage in Menga is not aligned to a solstice sunrise or sunset, as might be expected — instead, Menga points toward La Peña de los Enamorados, about 4 miles (6.5 km) to the northeast. (The other two megaliths in the region were built later and seem to point elsewhere.)

The alignment suggests La Peña was an important focus for local prehistoric people and solves a mystery of where Menga was pointing: to the location of both the rock art and the newly found tomb at  La Peña, while the tomb at La Peña itself pointed to the solstice sunrise, García Sanjuán said.  

The inner chamber of the newfound tomb is decorated with a distinctive stone with ripple marks on its surface, which was taken from a region that had once been a beach or part of the seabed.

The stone was placed so that the light from the rising midsummer sun fell upon it; the part of the burial chamber in front of it seems to have been kept clear of human remains, García Sanjuán said.

“These people chose this stone precisely because it created these waving, undulating shapes,” he said. “This was very theatrical… they were very clever in producing these special visual effects.”

He noted that megalithic structures have been found from Morocco to Sweden and that the people who built them seem to have had similar beliefs. 

“There are differences as well, but one common element is the sun,” García  Sanjuán said. “The sun was at the center of the worldview of these people.”

Archaeologists discover a new megalithic monument in the heart of Andalusia in southern Spain – a 5,000-year-old secret

Archaeologists in Spain uncovered a previously overlooked tomb while investigating the formation of La Peña de los Enamorados, also known as the sleeping giant.

The Antequera archaeological site in southern Spain is home to a number of ancient structures dating back to the third and fourth millennia BC, including the Menga, Viera, and El Romeral megaliths.

According to a study that was published on April 15 in the journal Antiquity, the Antequera site contains both man-made and “natural monuments,” but is best known for its prehistoric megaliths.

The “natural monuments” at the site include La Peña de los Enamorados, a stone “sleeping giant” that towers about 2,900 feet above the ground, researchers said.

The Sleeping Giant had a 5000-year-old secret hidden in his chest: Piedras Blancas megalithic grave.

The rectangular stone structure was built at least 5,000 years ago, according to the study. It was used for millennia in three distinct phases before being abandoned between 1950 and 1180 B.C.

Lead author of the new paper, Leonardo García Sanjuán, a Professor in Prehistory at the University of Seville (Spain), said the location of the Piedras Blancas tomb was “carefully chosen.”

The tomb’s stone slabs were carefully arranged to coincide “with the summer solstice sunrise,” researchers said. Some of the “heavily engraved” slabs “appear to have been precisely placed to ‘funnel’ the light from the rising sun towards the back of the chamber at the summer solstice.”

In Antequera, the oldest megaliths date back to 3,000 BC, and this rectangular stone tomb was built at the same time. Researchers believe that bodies were spread out on a sizable flat stone platform at the time ceramic offerings were left in the tomb. Later, the decomposing corpses were pushed off the stone platform and into the surrounding area, where the researchers discovered “40 teeth and 95 bones.”

Furthermore, the archaeologists identified a “triangular, arrow-like stone” lodged into the floor, oriented in the direction of the rising sun.

The Piedras Blancas tomb was renovated around 2500 B.C., and niches for two burials were added, according to the study. Researchers believe these were high-status individuals, most likely a man and a woman. It’s unclear whether they were buried simultaneously or over the course of a century.

The tomb later “underwent another significant transformation,” according to researchers. Stones were placed at the entrance “as if to block or seal” it, and the bones of at least two children and three women were interred.

According to the study, the tomb was abandoned and has remained untouched ever since.

‘Lost’ microbial genes found in dental plaque of ancient humans

About 19,000 years ago, a woman died in northern Spain. Her body was deliberately buried with pieces of the natural pigment ochre and placed behind a block of limestone in a cave known as El Mirón.

When her ochre-dyed bones were unearthed in 2010, archaeologists dubbed her the Red Lady. The careful treatment of her body provided scientists with insights into how people from the time buried their dead.

Now, thanks to the poor oral hygiene of that period, her teeth are helping illuminate a vanished world of bacteria and their chemical creations. From dental calculus, the rock-hard plaque that accumulates on teeth, researchers have successfully recovered and reconstructed the genetic material of bacteria living in the mouth of the Red Lady and dozens of other ancient individuals.

The gene reconstructions, reported today in Science, were accurate enough to replicate the enzymes the bacteria produced to help digest nutrients. “Just the fact that they were able to reconstruct the genome from a puzzle with millions of pieces is a great achievement,” says Gary Toranzos, an environmental microbiologist at the University of Puerto Rico who wasn’t involved in the work. “It’s ‘hold my beer, and watch me do it,’ and boy did they do it.”

Changes in diet and the introduction of antibiotics have dramatically altered the modern human microbiome, says University of Trento computational biologist Nicola Segata, who also wasn’t involved.

Sequencing ancient microbes and re-creating their chemical creations “will help us identify what functions our microbiome might have had in the past that we might have lost,” he says. Resurrecting these “lost” genes may one day help scientists devise new treatments for diseases, adds Mikkel Winther Pedersen, a molecular paleoecologist at the University of Copenhagen.

Within the past few decades, sequencing ancient DNA has illuminated physical and physiological features of long-dead organisms, but researchers have also used the same technique to examine the genes belonging to the teeming bacterial communities, or microbiomes, that once populated the mouths and guts of long-dead people.

That work has given them insights into which microbial species might have coexisted with humans before the advent of antibiotics and processed foods. But such understanding has been limited by the fact that researchers could only use modern microbes as references.

“We were limited to bacteria we know from today,” says Harvard University geneticist Christina Warinner, a co-author of the new study. “We were ignoring vast amounts of DNA from unknown or possibly extinct organisms.”

Breaking that barrier presented a monumental challenge. Reconstructing an oral microbiome—a soup of hundreds of different bacterial species, and millions of individual bacteria—from degraded ancient DNA is “like throwing together pieces of many puzzles and trying to solve them with the pieces mixed up and some pieces missing entirely,” Segata says.

Indeed, it took Warinner’s team nearly 3 years to adapt DNA sequencing tools and computer programs to work with the much shorter fragments of DNA found in ancient samples.

At long last, drawing on dental calculus from 46 ancient skeletons—including a dozen Neanderthals and modern humans who died between 30,000 and 150 years ago—Warinner and colleagues identified DNA from dozens of extinct or previously unknown oral bacteria.

Next, the team equipped modern Pseudomonas protegens bacteria with a pair of ancient genes to make proteins that produce milligrams’ worth of a molecule called a furan.

Modern bacteria are thought to use furans for cellular signaling. The new findings suggest ancient bacteria did, too—something that would have been impossible to predict by simply sequencing their genomes. “It’s wet-lab proof of what ancient genes were capable of,” says Pierre Stallforth of the Leibniz Institute for Natural Product Research and Infection Biology. “You can predict proteins based on DNA, but not necessarily the molecules those proteins are going to make.”

At first glance, the microbe they reconstructed seemed out of place in an oral microbiome. Identified as a type of bacterium called a chlorobium, its modern relatives use photosynthesis to survive on small amounts of light and live in anaerobic conditions, such as stagnant water. They aren’t found in modern mouths and appear to have vanished from ancient humans about 10,000 years ago.

This chlorobium might have entered the mouths of ancient people because they drank water in or near caves. Or, Warinner says, it might once have been a normal part of some people’s ancient oral microbiome, surviving on faint light penetrating the cheek.

Colleagues say dental calculus was an ideal place to start looking for these ancient microbes. Without regular cleaning, teeth trap leftover food and other organic matter in a mineral lattice, essentially encasing it in stone. That both helps preserve any DNA inside and protect it from contamination as the body decays. “Oral calculus is the perfect example of the best place you can find an uncontaminated sample,” Toranzos says. “There’s absolutely no way anything from the outside will get in.”

Although the researchers succeeded in prodding modern bacteria to express their previously undiscovered or extinct cousins’ genes, it’s a far cry from Jurassic Park, Warinner says. “We haven’t brought [the microbes] back to life, but identified key genes for making chemical compounds we’re interested in,” Warinner says.

The recovery of ancient microbial genes has the potential to illuminate our species’ relationship with bacteria over human evolution. Humans coevolved with their microbial partners and parasites for hundreds of thousands of years. The compounds produced by ancient microbes might have played important roles in digestion and immune responses. “Bacteria are not as charismatic as mammoths or woolly rhinos,” she says, “but they are nature’s chemists, and they’re key to understanding the past.”

2,600-year-old stone busts of ‘lost’ ancient Tartessos people were discovered in a sealed pit in Spain

Archaeologists in Spain have unearthed five life-size busts of human figures that could be the first-known human depictions of the Tartessos, a people who formed an ancient civilization that disappeared more than 2,500 years ago. 

The carved stone faces, which archaeologists date to the fifth century B.C., were found hidden inside a sealed pit in an adobe temple at Casas del Turuñuelo, an ancient Tartessian site in southern Spain.

The pieces were scattered amongst animal bones, mostly from horses, that likely came from a mass sacrifice, according to a translated statement published on April 18.

“The unusual thing about the new finding is that the representations correspond to human faces,” Erika López, a spokesperson for the Spanish National Research Council (CSIC), said in the statement. 

Archaeologists from the CSIC called this discovery “a profound paradigm shift in the interpretation of [Tartessos],” since this ancient civilization, which existed from about the eighth to the fourth centuries B.C., was long considered an aniconic culture in which divinity was represented through animal or plant motifs, rather than idolized humans, according to the statement.

Of the figurative reliefs, two are nearly complete and likely portray female divinities wearing earrings, which could be a nod to the Bronze Aged peoples’ adept goldsmithing skills.

Archaeologists found only fragments of the other three reliefs, but identified one as a warrior wearing a helmet, according to the statement.

Although the Tartessos didn’t leave much of an archeological record, archaeologists do know that they were skilled at goldsmithing; for instance, gold pieces similar to the reliefs’ earrings have been unearthed at two nearby Tartessian sites, Cancho Roano, and La Mata.

These locations were torched to the ground in a similar manner to the newly discovered pit site, but why and how these conflagrations occurred remains a mystery, according to an April 21 Vice article.

Some historians, including the Greek philosopher Aristotle, once linked the Tartessos people to the mythical lost city of Atlantis. However this idea “has been widely dismissed in the scientific community,” according to a 2022 BBC article. 

“The finding only further influences both the importance of the site and the importance of the Tartessian culture in the Guadiana valley during its last moments,” López said in the translated statement.

Smoke archeology finds evidence Humans visited Nerja Cave for 40,000 years

A new study by a team from the University of Córdoba reveals that Nerja is the European cave with the most confirmed and recurrent visits during Prehistory.

Humans have been visiting the Cave of Nerja for 41,000 years; for a few of them, it has been exploited as a tourist attraction, and for nearly the same amount of time, it has been the subject of scientific study.

Throughout its history, and even today, it continues to stun visitors and researchers from around the world.

The latest surprise from the cave, located in the province of Malaga, was just published in Scientific Reports by an international team including researchers from the University of Córdoba; Marian Medina, currently at the University of Bourdeux; Eva Rodríguez; and José Luis Sachidrián, a Professor of Prehistory and the scientific director of the Cave of Nerja.

They have managed to demonstrate that Humanity has been present in Nerja for some 41,000 years, 10,000 years earlier than previously believed, and that it is Europe’s cave featuring Paleolithic Art in Europe with the highest number of confirmed and recurrent visits to its interior during Prehistory.

This new research has managed to document 35,000 years of visits in 73 different phases, which means that human groups entered the cave every 35 years, according to their calculations.

This level of precision has been made possible thanks to the use of the latest techniques dating the coals and remains of fossilized soot on the stalagmites of the Nerja Cave.

This is what has been called “smoke archaeology,” a new technique developed by the main author of the work, Marián Medina, from Córdoba’s Santa Rosa district, an honorary researcher at that city’s university, who has been reconstructing European prehistory for more than a decade by analyzing the remnants of torches, fires, and smoke in Spanish and French caves.

With the enthusiasm of one who loves what she does, Medina explains that the information that Transmission Electron Microscopy and Carbon-14 dating techniques can provide on man’s rituals and ways of life is impressive.

In this last work, 68 datings are presented, 48 totally new, of the deepest areas of the cave, featuring Paleolithic Art, and evidence of chronocultures never previously recorded has been found.

Furthermore, these “fire archaeologists” understand how to interpret the way the torches were moved based on the information detected under the microscope, inferring from it the symbolic and scenographic use that humans made of fire 40,000 years ago.

“The prehistoric paintings were viewed in the flickering light of the flames, which could give the figures a certain sense of movement and warmth,” explains Medina, who also underscores the funerary use of the Nerja Cave in the latter part of Prehistory, for thousands of years. “There is still much it can reveal about what we were like,” she says.

The study was published in Scientific Reports.

Unique and very well-preserved prehistoric engravings found in southwestern Catalonia

Significant prehistoric rock art has been discovered in La Febro, in southwestern Catalonia. The team that discovered the art inside Cova de la Vila described it as “exceptional, both for its singularity and excellent state of conservation.”

In the Cova de la Vila cave in La Febró (Tarragona), in northeastern Spain’s region of Catalonia, more than 100 prehistoric engravings have been found, arranged on an eight-meter panel.

According to experts, it is a composition related to the worldview of agricultural societies and farmers of the territory. One of the singularities of this mural is that it is made exclusively with the engraving technique, with stone or wood tools.

The engravings include shapes that resemble horses, cows, suns, and stars.

Julio Serrano, Montserrat Roca, and Francesc Rubinat were the cavers responsible for the discovery; they collaborated with Josep Vallverd, Antonio Rodrguez-Hidalgo, and Diego Lombao, researchers from the Catalan Institute of Human Paleoecology and Social Evolution (IPHES-CERCA), and Ramón Vias, an expert in prehistoric rock art.

It was in May 2021, during some scans and topographical work by a group of speleologists in the Barranc de la Cova del Corral, that they discovered the Cova de la Vila, a cavity excavated by Salvador Vilaseca in the 1940s and whose coordinates appear to have been lost.

The set is very homogeneous stylistically and presents few overlaps. From the stylistic point of view, the set is part of the post-Paleolithic schematic art. It is an art associated with peasant and livestock communities during the transition period between the Chalcolithic and the Bronze Age, that is, between 5,000 and 3,000 years BC.

In Catalonia, these types of ensembles, in underground cavities, are very rare, being the case of the Sala dels Gravats of the karstic complex of Cova de la Vila exceptional for being inside a cave and possibly associated with an archaeological context.

These types of representations are uncommon in Catalan territory, though some examples can be found, such as the Vallmajor Cave in Albinyana, Baix Penedès. In the peninsular area, it would be classified as “underground black schematic and abstract schematic,” which are heterogeneous groups distinguished by their formal or typological, thematic, and technical affinities.

La Pileta and Nerja in Málaga, La Murcielaguina in Córdoba, and the Los Enebralejos caves in Segovia, the Galera del Flex in Burgos, or the Maja Cave in Soria are some Andalusian caves with painted (black or red) or engraved representations and similar chronologies.

The engravings are in exceptional condition, but they are extremely fragile due to the instability of the support on which they are found. Because it is a soft and humid surface, changes in the atmospheric conditions in the room may affect the conservation of the panel.

To ensure these climatic conditions, the Department of Culture, the Febró Town Hall, and the IPHES collaborated to close it both outside and inside, ensuring its physical conservation. Similarly, a closure has been installed in the access to the cat flap, which provides direct access to the Sala dels Gravats, to return it to the climatic conditions it had prior to discovery.

A unique set of engravings

The rock art collection of the Sala dels Gravats of the Cova de la Vila karstic complex is completely unique. Despite the fact that its research phase has not yet begun, all indications point to it being one of the best compositions of post-paleolithic subterranean abstract art in the entire Mediterranean region.

On one of the cave walls, a large number of schematic representations have been discovered. The engraving panel is made up of five horizontal lines, one on top of the other, with different engraved figures that each have their own meaning and symbolism.

Various figures such as quadrupeds, zigzags, linear, angular strokes, and circles are represented. There are several zoomorphs (possibly bovids and equines), steliforms (single and/or stars), and reticulates that stand out. There’s also a composition that looks like an ‘eyeballed’ idol. The overall aesthetic is very consistent, with few stylistic overlaps.

The distribution of the various elements suggests that it could be a composition: zoomorphic in the lower part of the panel, reticulated, particularly in the central part, and steliform in the upper part of the group, with an eye in the upper part of the group.

Prehistoric “Engravings Room” Rediscovered in Spain

More than 100 prehistoric engravings have been discovered, arranged on an eight-meter panel, inside the cave known as Cova de la Vila, in La Febró (Tarragona), in Spain’s northeastern region of Catalonia.

The depictions found in the Mediterranean underground gallery have been described as “exceptional, both for their singularity and for their excellent state of conservation” by a team from the Catalan Institute of Human Paleoecology and Social Evolution (IPHES).

According to IPHES specialist Ramón Viñas, this mural represents the world view of first farmer societies during the Chalcolithic-Bronze age.

The engravings were first discovered on May 13, 2021 by a group of three cave explorers and subsequently underwent analysis by archaeologists and paleontologists from IPHES, the institute said in a statement.

Among the cave art samples, there are representations of different figures of quadrupeds, zigzags, linear, angular and circular lines, and a series of zoomorphs (possibly bovids and equines), star shapes and reticular lines.

The discovery of the cave art constitutes “one of the few representations of underground schematic art in the entire Mediterranean Arc,” said the regional government of Catalonia.

The discovery marks “a historic milestone for prehistoric archaeology,” according to IPHES.

The cave had been explored by Salvador Vilaseca in the 1940s, but its location had been lost. IPHES researchers managed to open a small hole between blocks of stone and came into an oval room of more than 90 square meters.

The first person to enter was Juli Serrano, who, to his surprise, saw a “mural full of lines and figures.” He says that when he came into the large, circular cavity and saw what it contained, he felt “a very great emotion, which I will take with me for life.” Without knowing it, he had just discovered one of the most important assemblages of prehistoric cave art. From that moment on, researchers Ramon Viñas and Josep Vallverdú from IPHES got to work on the site.

Viñas underscored how the panel of engravings is structured along five horizontal lines, one on top of the other, and how each of them contains different engraved figures that have their own meaning and symbolism.

The scientist points out that it is an “absolutely unusual” composition that indicates “a worldview on the part of the populations of the territory during the neolithization process.”

One of the singularities is that this cave art was made “exclusively with the engraving technique,” using a stone or wooden tool or directly with the fingers, explained Viñas.

The researcher considers that this, as well as the fact that it is “stylistically very homogeneous,” indicates a symbolic meaning. It is not a composition that is the result of chance.

During the transition period between the Chalcolithic and the Bronze Age, between the late 5th and the late 3rd millennia BC, human groups were generally found outdoors, their presence being very scarce in the underground cavities of Catalonia, in the northeast of the Iberian peninsula. Elsewhere in Spain, instances of underground dwellings have also been found in Andalusia, Segovia, Burgos, and Soria.

To guarantee its conservation, the regional government has closed access to Sala dels Gravats (Engravings Room). The site has been designated a cultural asset of national interest and work is underway to create a 3D model of the cave.
