The Vesuvius volcanic explosion in 79A.D. is known for its relation to Pompeii. The volcanic ashes from the eruption buried Pompeii and many of its neighboring settlements.

The BBC reported that Herculaneum, another settlement that fell victim to the volcanic eruption at that time, recently revealed one of the most significant insights into the Roman lives 2000 years ago.

A tunnel 86m long and one of the largest deposit of human excrement ever to be found was discovered in Herculaneum, containing nearly seven hundred and fifty sacks of excrements.

From these excrements, scientists were able to study foods ancient Romans ate and jobs they took. They have so far provided an “unprecedented insight into the diet and health of ancient Romans” as BBC reporter has said.

The sewer was reported to contain other key artifacts like potteries, coins, a lamp and other various decorative ornaments.

Showing insight into the lives of Romans that walked Herculaneum nearly 200 years ago, these artifacts have truly become the “treasures in the sewers.”
