A new study reveals that bathing in ancient Pompeii was not as clean as previously thought, due to infrequent water changes in communal areas. Research from Germany's University of Mainz indicates that the city's bathing culture was influenced by Greeks and Samnites before the Roman invasion. Evidence from calcium carbonate deposits shows human contamination in the water system, which was preserved by lava from the eruption of Mount Vesuvius in 79 AD. The study highlights the evolution of Pompeii's water system and the impact of the Samnites and Romans on communal bathing practices. Teljes cikk (Euronews.com)
