Pompeii represents an unprecedented stratigraphic section in the history of conservation, offering us a snapshot of an ancient restoration site frozen in action. When the eruption of Vesuvius sealed the city in 79 AD, its inhabitants were still actively healing the wounds of the devastating earthquake of 62 AD, transforming houses and public buildings into a vast open-air laboratory. In contexts such as the House of the Painters at Work, this sudden interruption froze the daily practices of Roman craftsmen, leaving behind site tools like plumb bobs, trowels, and compasses, along with bowls filled with pure pigments, guide incisings on fresh plaster, and half-finished walls. The deep theoretical knowledge of the era, also recorded by Vitruvius, was reflected in the use of complex plaster layers enriched with marble dust and the application of fresco pigments like natural earths and Egyptian Blue, alongside refined wax coatings for more delicate hues. For modern conservation, this Pompeian freeze-frame offers invaluable lessons: it teaches the central importance of preventive restoration against moisture, shows the effectiveness of traditional lime-based materials over harmful contemporary synthetic binders, and, above all, demands respect for historical stratigraphy—reminding us that every intervention, even one carried out by the Romans two thousand years ago, becomes an inseparable part of the artwork and its history.
