Science behind the preservation of the bodies left behind by the eruption
The bodies preserved at Pompeii and Herculaneum owe their condition to the innovative techniques developed by archaeologist Giuseppe Fiorelli in the 19th century. When Mount Vesuvius erupted, the people of these cities were overwhelmed by a sudden onslaught of rocks, debris, and suffocating gases, many succumbing instantly to the intense heat. Buried under 6 meters of ash that solidified over centuries, their bodies decayed, leaving voids in the ash shaped by their final moments.
Fiorelli developed an innovative technique to bring these voids back to life. By carefully pouring plaster into the cavities, he was able to create detailed casts that captured not just the positions in which people met their fate, but also intricate details like their clothing, hairstyles, and, in some cases, their final expressions.
