Science occasionally gives us clearer views of the distant past. This year, researchers opened windows into the life and times of ancient Romans, impressionist painters and other towering historical figures.
What did the ancient Romans smell like? Chemical analyses of a 2,000-year-old perfume bottle from an elite woman’s grave suggest a familiar earthy scent: patchouli (SN: 7/1/23, p. 14). Patchouli oil permeates modern fragrances, but its use in ancient Rome had been unknown. Perfume extracts that are this old typically dissipate and become lost to history. But the quartz flask was found intact with a bitumen seal that adsorbed some of the perfume molecules, preserving them for millennia.
Infrared and X-ray scans of more than 600 paper bills made by Benjamin Franklin’s prolific printing press revealed colorful threads and shiny mineral residues (SN: 8/26/23, p. 5). The additives, used to stymie counterfeiters and boost the bills’ durability, helped set the standard for paper currency in colonial America, researchers say.
Ludwig van Beethoven’s DNA supports what many historians have suspected: The composer likely died of liver failure (SN: 4/22/23, p. 16). Until now, the theory largely rested on reports that Beethoven had been drinking a lot of alcohol shortly before his death in 1827. While reconstructing Beethoven’s genome from samples of his hair, researchers discovered he also had a genetic risk for liver disease. The composer also suffered from a hepatitis B infection, the team determined, further compounding his susceptibility to liver damage.
