Ancient sewer excavation sheds light on the Roman diet
Herculaneum and its neighbor Pompeii were among the towns destroyed by being buried under volcanic ash by the eruption of Mount Vesuvius in 79 AD.
The archaeologists, from the British School in Rome, have been working their way through over 770 bags of compacted human waste from a 86-meter long sewer system under the remains of a three-storey apartment block in the city. The system was in effect a large septic tank with wastes from the building above being tipped into it via a series of chutes. Along with compacted excrement they have also found objects such as coins, rings, precious stones, beads, and bone hairpins.
The archaeologists working on the Herculaneum Conservation Project found the drains by accident while searching for a way to prevent the site from being flooded during heavy rain periods. The system contains the largest deposit of organic matter dating from Roman times ever found. Director of the project, Professor Andrew Wallace-Hadrill, said the discovery was the largest find of Roman waste, but had it been found the past it would have been thrown away because archaeologists did not have the technology available today to analyze it.
Archaeologists have been working on the site for ten years and have discovered a wide variety of objects such as glassware, crockery, pots and pans. A number of human skeletons have also been unearthed. Among the objects discovered were pots of “ingenious construction,” which Wallace-Hadrill said might have been used to fatten up dormice for eating.
