(Herculaneum, by the way, was a neighboring city to Pompeii, and it was likewise destroyed and buried in the eruption of Mt. Vesuvius in 79 A.D.)
I don’t want to get in trouble for corrupting young minds (again), so I can’t tell you straight out what the “brown gold” is. But let it be known that this rich seam is telling archaeologists a lot about what the ancient residents of Herculaneum ate. Also, it rhymes with “trap.”
Recovered from an 86-meter-long septic tank-like section of sewer, the ancient, compacted gold fills over 770 bags, and seems to indicate that the buildings’ former residents, despite their low- or middle-class status, had a surprisingly varied diet. They ate fish, vegetables, fruit, eggs, olives, walnuts, sea urchins, and lots of figs. Also, they ate dormice, which is simply adorable.
Archaeologists working at the site say that it’s lucky that the gold wasn’t discovered before, because the technology for analyzing the material wasn’t available until relatively recently. Also they just didn’t appreciate this sort of thing back then.*
*This last statement is based on how I imagine my grandmother would react if I explained the discovery to her. Fortunately she’s dead, so it probably won’t come up.
