AI helps read papyrus scroll burnt to crisp during Vesuvius eruption
Artificial Intelligence Unveils Ancient Stoic Text from Herculaneum's Burned Scrolls
AI helps read papyrus scroll burnt - More than 2,000 years after the catastrophic eruption of Mount Vesuvius, a breakthrough in ancient text recovery has brought new life to a long-buried papyrus scroll. The fragment, designated PHerc 1667, was carbonized during the volcanic event that destroyed the nearby city of Pompeii in AD79. Now, researchers have used artificial intelligence to virtually unwrap and decipher the scroll, revealing insights into Stoic philosophy that were previously hidden beneath layers of charred material. This achievement marks a pivotal moment in the study of the Herculaneum library, a collection of hundreds of scrolls preserved in a luxury Roman villa that was buried under ash and heat, effectively freezing its contents in time.
Virtual Unwrapping: A New Approach to Ancient Texts
Unlike traditional methods that risk damaging fragile scrolls, the latest technique allows scholars to "see" the text without physical intervention. By analyzing high-resolution X-ray images, researchers have successfully uncovered 20 columns of previously concealed writing on a papyrus fragment that measures over a metre in length. The AI system, trained to detect subtle variations in the papyrus fibers, reconstructs the text by identifying ink traces that remain invisible to the naked eye. This process has been instrumental in preserving the scroll's integrity while unlocking its secrets.
The scroll, now only half its original size—measuring 8cm in height and 2cm in width—was found in a state of severe degradation. Over time, it had been broken in two, and earlier attempts to unwrap it caused outer layers to flake away or disintegrate. Despite these challenges, the virtual reconstruction has enabled scholars to access its content, which includes a Stoic treatise on ethics, art, and human behavior. This discovery is particularly significant because the scroll predates much of the known Stoic literature, dating back to the second or late-third century BC. Its age and themes suggest it may have been authored by a different philosopher than the prominent Epicurean Philodemus, who is believed to have dominated the Herculaneum library.
The Vesuvius Challenge: A Global Effort to Decipher Lost Knowledge
The project, part of the Vesuvius Challenge, launched in 2023 as an international initiative to decode the carbonized scrolls. Teams from around the world have competed to develop the most advanced algorithms for virtual unwrapping, with hundreds of thousands of dollars in prizes awarded for innovative techniques. The success of this endeavor has not only demonstrated the power of AI in archaeology but also shifted the focus of the research from technical recovery to interpretive analysis. As Dr. Federica Nicolardi, a papyrologist at the University of Naples Federico II, noted, the ability to unwrap these scrolls "completely" is a milestone that underscores the potential of modern technology to revive ancient wisdom.
The scroll's contents, which center on the Stoic concept of hormē—defined as impulse or the force that drives action—highlight the philosopher's emphasis on reason as a tool for controlling emotions and achieving self-mastery. One passage warns that failing to regulate behavior with rational thought can lead to destructive passions and a loss of focus on one’s goals. The text also explores phronēsis, or practical wisdom, a cornerstone of Stoic ethics. The author’s assertion that "We will inquire into something, but we will not grasp it, if in some way we depart from ourselves and from our own nature" underscores the belief that innate human goodness and rationality are essential for true understanding.
“These unopened Herculaneum Scrolls look like dead books, but they’re not,” said Nicolardi. “They’re starting to speak again.”
From Unread to Unraveled: The Journey of a Hidden Manuscript
The process of decoding PHerc 1667 began with the realization that the scroll’s text was obscured by layers of carbonized material. Traditional methods of unrolling had proven ineffective, as the fragile papyrus would disintegrate under pressure. However, advancements in X-ray imaging and AI have transformed this challenge into an opportunity. By training machine-learning models to recognize patterns in the fibrous structure of the papyrus, researchers can simulate the act of unrolling and reconstruct the text digitally. This method has been particularly useful for scrolls that were never fully unrolled in antiquity, as they remained intact for centuries under volcanic ash.
While Philodemus of Gadara, a first-century BC Epicurean philosopher, is the most famous figure associated with the Herculaneum library, the contents of PHerc 1667 suggest a different voice. The text’s focus on Stoic principles, such as the interplay between impulse and reason, points to a possible authorship by Chrysippus, the third head of the Stoic school. His presence in the collection adds a new layer of intrigue, as his other works have been identified, but this scroll may offer a previously unknown perspective. The discovery raises questions about the diversity of philosophical thought in the Roman world and the extent of Stoic influence beyond Philodemus’s known contributions.
“People now know that this can be done and now we’re exploring what [the texts] actually mean,” said Prof. Brent Seales, the computer scientist who pioneered the Vesuvius Challenge. “For me that’s the World Cup. I just won the World Cup: that’s my victory.”
The breakthrough has also sparked renewed interest in the Herculaneum library as a repository of ancient knowledge. The scrolls, preserved in a villa that was buried by the eruption, are considered some of the best-preserved examples of ancient Greek literature. The recent unveiling of PHerc 1667, alongside other scrolls like one containing the title “Philodemus, On Gods, Book 8,” has expanded the understanding of the library’s scope. Prior to these discoveries, only fragments of Philodemus’s works were known, but the new findings indicate that the collection may have included a broader range of philosophical texts.
As the Vesuvius Challenge continues, its impact extends beyond technical innovation. The ability to read these scrolls has opened a dialogue between ancient philosophy and modern scholarship, enabling a deeper exploration of Stoic ideas. The AI-driven reconstruction not only preserves the physical remains of the scrolls but also ensures their intellectual legacy endures. With each new discovery, the team at the University of Naples Federico II and its collaborators are bringing the voices of the past into the present, offering fresh insights into the enduring relevance of Stoic thought. The scroll’s survival, despite the ravages of time and fire, stands as a testament to the resilience of human knowledge—and the transformative power of artificial intelligence in uncovering it.
The Future of Ancient Text Recovery
Prof. Seales’s work with machine-learning algorithms has been foundational to this progress, proving that technology can bridge the gap between the past and the present. His techniques, which rely on the contrast between ink and carbonized fibers in X-ray images, have set a new standard for the field of papyrology. As the project evolves, the focus is shifting from the mechanics of reading to the interpretation of meaning. This transition is critical for understanding the philosophical underpinnings of the texts and their significance in the broader context of ancient Mediterranean thought.
The recent success with PHerc 1667 is a prime example of how AI can unlock the mysteries of carbonized materials. The scroll’s virtual unwrapping has revealed a treatise that delves into the Stoic concept of hormē, emphasizing the importance of rational control over emotions. This theme aligns with Stoic ideals, which prioritize reason as the guiding force in human life. The text’s exploration of phronēsis further reinforces this focus, suggesting that practical wisdom is the pinnacle of ethical behavior. These insights not only enrich our understanding of Stoic philosophy but also provide a glimpse into the intellectual life of the Roman world.
With the Herculaneum scrolls now being "read" in a new way, the future of ancient text recovery looks promising. The combination of X-ray imaging, machine learning, and interdisciplinary collaboration has transformed the field, enabling scholars to access texts that were once thought lost forever. As more scrolls are decoded, the potential for uncovering new philosophical ideas or historical narratives grows. The Vesuvius Challenge exemplifies how technology can aid in the preservation and interpretation of the past, ensuring that the wisdom of ancient thinkers continues to inspire and inform contemporary discourse.
