The military helmet that was found by divers off the coast of Sicily, Italy. The artifact is thought to date to between the late 15th and 17th centuries.SOPRINTENDENZA DEL MARE

The find, announced by the Superintendency of the Sea for the region (Soprintendenza del Mare), unfolded near the Vendicari Nature Reserve in eastern Sicily, a region teeming with historical intrigue. At a relatively shallow depth of just 16 feet, the divers—led by underwater cultural heritage expert Matteo Azzaro and researchers from the University of Naples—encountered the ancient artifact, triggering excitement and curiosity among maritime archaeologists.

The helmet, believed to belong to the "cabasset" or "capacete" style commonly worn by infantry troops during the late 15th to 17th centuries, holds significant historical value. Its presence on the seabed hints at a potential connection to maritime activities of the past, possibly linked to a previously undocumented shipwreck.

A map shows the location of the Vendicari Nature Reserve, which lies on the southwest coast of Sicily. The helmet, thought to date to between the 15th and 17th centuries, was found on the seabed nearby.

Salvatore Emma, spokesperson for the superintendency, highlighted the importance of the discovery and its implications for further research. "The finding of this military helmet is very important," Emma stated. "It could be related to the presence of a previously unknown shipwreck, but further investigations are needed to confirm this hypothesis."

In the coming weeks, the Soprintendenza del Mare plans to conduct underwater reconnaissance missions in the vicinity of the discovery site. Utilizing divers and specialized equipment such as underwater metal detectors, the team aims to uncover additional clues that could unravel the mystery surrounding the helmet's origin and the potential existence of an associated shipwreck.

The geographical context adds layers of intrigue to the discovery, as the waters off Sicily witnessed naval skirmishes between English and Spanish fleets during the 15th to 17th centuries. Emma noted, "Not far from the place of discovery, cannons belonging to boats of the same period have already been identified. Future investigations will be carried out to verify whether there is a correlation between the episodes."

Despite being encrusted with concretions—a common occurrence on marine artifacts—the helmet remains remarkably intact, offering a tantalizing glimpse into the past.

Geometric Petroglyphs at Toro Muerto: Ancient Songs in Stone

A groundbreaking study, recently published in the Cambridge Archaeological Journal, unveils a fascinating interpretation of the enigmatic petroglyphs found at Toro Muerto in Peru. These intricate carvings, etched into over 3000 volcanic rocks, have long puzzled archaeologists and historians, but a new theory suggests they may represent something unexpected: ancient songs.

Toro Muerto, meaning "Dead Bull" in Spanish, is situated in Peru's Castilla province and is renowned for its extensive collection of petroglyphs dating back to the Wari Culture, which thrived between AD 500 to 1000. Among the myriad petroglyphs adorning the site are dancing anthropomorphic figures, known as danzantes, accompanied by geometric motifs such as zigzag lines and concentric circles.

While previous interpretations linked these zigzag lines to symbols of snakes or lightning, with potential associations to fertility and water cults, the new study offers a fresh perspective. Drawing parallels with the Tukano people of the Colombia rainforest, renowned for their art rooted in visionary experiences induced by psychoactive rituals, the study posits that the petroglyphs at Toro Muerto may be abstract representations of ancient singing and songs.

The Tukano people, known for their art featuring concentric circles, dots, wavy lines, zigzags, and crenellation motifs, used these symbols to evoke creation myths and other topics expressed through dances and songs. Moreover, similar motifs found in Mesoamerican iconography, such as Maya, Mixtec, and Nahua codices, are theorized to depict songs in visual form, representing the sonic sphere of culture.

Building on this premise, the study suggests that the graphic depiction of songs in petroglyphs might not be unique to Toro Muerto but could have been a widespread phenomenon in various cultures, including the Wari civilization. The authors propose that certain compositions featuring dancers and linear geometric patterns symbolized journeys to the afterlife, adding another layer of complexity to the interpretation of these ancient artworks.

"In our study, we show that some geometric images could have been representations or embodiments of songs themselves, in their own right, independent of any depictions of mouths or bodies," explain the study authors. "We base this study on the case of the petroglyphs at Toro Muerto in Peru, while the source of our interpretative proposal is ethnographic knowledge, more precisely an ethnographic analogy from Amazonia, specifically the art of the Tukano people."

As scholars continue to unravel the mysteries of Toro Muerto and its petroglyphs, this innovative interpretation offers a captivating glimpse into the intersection of art, culture, and ancient storytelling practices. It underscores the enduring significance of these enigmatic symbols and their potential to unlock the secrets of Peru's rich cultural heritage.

In a groundbreaking study published in the Proceedings of the National Academy of Sciences of the United States of America, researchers shed light on the remarkable geological acumen of Stone Age humans inhabiting what is now South Africa approximately 70,000 years ago. Led by archaeologist Patrick Schmidt from the University of Tübingen in Germany, the study unveils the sophisticated understanding early humans possessed regarding the properties of various rocks used in toolmaking.

Insightful Stone Selection

Contrary to previous assumptions, Stone Age humans displayed a nuanced understanding of the rocks available in their environment, selecting materials based on their suitability for crafting finely honed tools. Schmidt's team developed a mathematical formula to quantitatively assess rock properties, including strength and fracture resistance. By applying this methodology to rocks collected from the Diepkloof site in South Africa, inhabited by Stone Age communities for millennia, researchers uncovered compelling insights into ancient rock selection practices.

Stone Age Geology Unveiled

Rocks were not mere inert objects to Stone Age communities but represented a canvas of possibilities. From knapping knife blades to spear points and ax heads, early humans harnessed the potential of rocks, offering archaeologists a unique glimpse into their culture. By analyzing rock properties, researchers discerned distinct preferences among ancient toolmakers, with specific types of rocks favored for different tool types.

Insights from Stone Tool Evolution

Examining tool evolution over time, researchers observed shifts in rock preferences corresponding to changes in tool design and function. For instance, the Still Bay technocomplex, active around 71,000 years ago, favored quartzite for its predictability and durability, ideal for crafting spear tips. In contrast, later communities, such as those from the Howiesons Poort technocomplex around 65,000 years ago, gravitated towards silcrete, prioritizing ease of flaking for producing arrowheads and spear points.

Challenges and Future Directions

While the study provides compelling evidence of Stone Age humans' sophisticated stone selection, challenges remain in fully understanding ancient toolmaking practices. Practical experiments, involving replicating stone tools and assessing their performance, offer valuable insights into the dynamic relationship between humans and their tools. Additionally, future research should consider variations in rock properties within categories like quartzite and silcrete, enhancing our understanding of ancient decision-making processes.

Conclusion

The study marks a significant milestone in our understanding of Stone Age ingenuity, highlighting the resourcefulness and expertise of ancient humans in navigating their geological surroundings. By unraveling the mysteries of ancient toolmaking, researchers continue to unveil the remarkable complexities of human adaptation and innovation across millennia.
