Key Takeaways
- Researchers uncovered 79 previously unseen graffiti inscriptions in a narrow corridor linking Pompeii’s two theatres using Reflectance Transformation Imaging (RTI).
- The new findings include a fragmentary love declaration to someone named Erato, gladiator combat sketches, animal drawings, ships, and numerous phallic symbols.
- Graffiti reveal the voices of enslaved, impoverished, and ordinary Pompeiians—groups largely absent from elite historical records.
- The inscriptions illuminate aspects of class, gender, and popular culture, showing that women rarely authored graffiti despite appearing in the messages.
- RTI, a night‑time photographic technique that creates a 3D digital model from shifting light, made faint scratches legible without damaging the walls.
- The project, Bruits de couloir, plans to launch a public digital platform in June that will let anyone explore the corridor’s graffiti online.
- Although AI was not used in this study, park officials see future potential for AI to animate or interpret the ancient markings.
- The corridor is deemed one of Pompeii’s most important spaces for understanding daily life before the AD 79 Vesuvius eruption.
Discovery of New Graffiti
In 2022 and 2025, an international team led by Louis Autin and Éloïse Letellier‑Taillefer of Sorbonne University, together with Marie‑Adeline Le Guennec of Université du Québec à Montréal, conducted two field seasons in the corridor between Pompeii’s Teatro Grande and Odeion. They re‑examined roughly 300 known inscriptions and identified 79 entirely new ones that had been worn to the edge of legibility. The breakthrough came from applying Reflectance Transformation Imaging (RTI), a photographic method that captures surface details under varying light angles and reconstructs them as a manipulable 3D model. By working at night inside the corridor and using an RTI acquisition dome built by the French firm Mercurio Imaging, the researchers turned faint scratches into clear, readable text and drawings.
The Erato Love Inscription
Among the newly revealed graffiti is a fragmentary declaration of love addressed to someone named Erato. The inscription reads roughly “I love Erato,” but the lover’s name has been lost to time. Erato was one of the nine Greco‑Roman muses associated with love poetry; in ancient Rome the name also meant “beloved.” Le Guennec notes that names like Erato were commonly given to freedpeople or slaves, who were often rebaptized by owners with stereotypical, muse‑derived names. The phrasing uses colloquial slang typical of working‑class Pompeiians, suggesting the message originated from a modest social stratum rather than an elite patron. Though incomplete, the graffito offers a rare glimpse into personal affection among the city’s non‑elite residents.
Depictions of Daily Life and Entertainment
Beyond textual messages, the corridor walls contain vivid drawings that capture Pompeiians’ visual interests. One sketch, interpreted by Gabriel Zuchtriegel, director of the Archaeological Park of Pompeii, shows figures that appear to be gladiators engaged in combat, possibly alongside an animal hunt. Other illustrations depict ships, various animals, and numerous phallic symbols—a motif ubiquitous across the Roman world. Le Guennec explains that sexual attributes were viewed as signs of prosperity and fertility, so their exaggerated, sometimes humorous portrayal fits Roman popular imagery. The presence of both masculine and feminine sexual representations indicates a broad, albeit playful, engagement with themes of potency and desire.
Graffiti as a Window onto Ordinary People
Historical records and the remains of lavish villas predominantly reflect the lives of Pompeii’s wealthy elite. Graffiti, by contrast, preserves the voices of enslaved laborers, poor freemen, women, and everyday citizens who left little else behind. The corridor’s inscriptions reveal jokes, insults, declarations of love, and casual doodles—behaviors that mirror modern street art and social media commentary. This “popular communication” shows that even in a highly stratified society, ordinary people found ways to assert identity, humor, and desire on public surfaces.
Class, Gender, and Access to Literacy
Le Guennec observes that while women appear frequently as subjects of graffiti—mentioned in love notes or insults—they rarely appear as authors. This disparity points to limited access to formal education and perhaps to social norms that discouraged women from marking walls publicly. Men, especially those from lower socioeconomic strata, dominate the corpus of authorship, suggesting that literacy—or at least the confidence to write—was more widespread among male workers. The graffiti thus serve as an indirect measure of educational opportunity and gendered participation in public expression.
The Vesuvius Eruption and Pompeii’s Preservation
The graffiti were frozen in time when Mount Vesuvius erupted in AD 79, burying Pompeii under volcanic ash and pumice. The sudden burial preserved not only buildings and artifacts but also the delicate surface markings on walls. Today, the site is a UNESCO World Heritage Site, and the Archaeological Park of Pompeii welcomes millions of visitors each year. A poignant reminder of the disaster is the plaster cast of a victim, made by filling the void left by a decomposing body—a technique that similarly captures the fleeting moments of daily life halted by the eruption.
Visitor Reflections and Modern Connections
Lorna Bieber, a visitor from New York, remarked that walking through the corridor felt strangely contemporary. She noted that ancient Pompeiians were “playful, obscene, funny, and wanting to leave their mark,” much like modern graffiti artists. The realization that people two millennia ago engaged in similar impulses for expression and humor creates a palpable link across centuries, underscoring the universality of certain human behaviors despite cultural and technological differences.
Technical Details of the RTI Technique
Reflectance Transformation Imaging involves photographing a flat surface dozens of times while shifting the direction of illumination. Each image records how light interacts with minute topographical variations, producing a series of shadow patterns. A computer algorithm then synthesizes these images into a 3D digital model that can be re‑lit from any angle on screen, making otherwise invisible inscriptions pop into view. Because the method relies solely on photography, it is non‑invasive and suitable for fragile heritage surfaces like the plastered walls of the Pompeian corridor. The team’s use of an RTI acquisition dome allowed them to control lighting precisely while working within the confined space after hours.
Future Plans: A Public Digital Platform
In June 2025, the Bruits de couloir team intends to launch an open‑access digital platform that will combine photogrammetry of the corridor, the high‑resolution RTI data, and the complete epigraphic record of the 79 new inscriptions plus the previously known ones. Users will be able to navigate a virtual reconstruction of the passageway, zoom in on individual graffiti, and read transcriptions and translations. By bringing the “corridor whispers” to a global audience, the project aims to democratize access to this intimate slice of ancient life and inspire further interdisciplinary research into Roman popular culture.
Potential Role of Artificial Intelligence
Although the current study did not employ artificial intelligence, park archaeologist Giuseppe Scarpati notes that the Archaeological Park has already experimented with AI to visualize a Vesuvius‑era fleeing citizen carrying a terracotta bowl. He expresses enthusiasm for applying similar AI tools to the graffiti—perhaps to enhance faded pigments, reconstruct missing text fragments, or even animate the scenes depicted in the drawings. Such technologies could one day allow scholars and the public to experience Pompeii’s street art not just as static images, but as dynamic stories echoing across two millennia.
