We often uncover about the past visually—by draw of oil paintings and sepia photos, books and constructions, artifacts displayed in the support of glass. And usually we secure to touch historical objects or listen to recordings. But infrequently ever produce we spend our sense of smell—our oldest, most primal means of learning about the atmosphere—to ride the far-off past.
With out secure admission to to odor, “you lose that intimacy that smell brings to the interaction between us and objects,” says analytical chemist Matija Strlič. As lead scientist of the Heritage Science Laboratory at the College of Ljubljana in Slovenia and previously deputy director of the Institute for Sustainable Heritage at College College London, Strlič has devoted his profession to interdisciplinary overview in the area of heritage science. Essential of his work taking into consideration the preservation and reconstruction of culturally valuable scents.

Reconstructed scents can toughen museum and gallery shows, says Inger Leemans, a cultural historian at the Royal Netherlands Academy of Arts and Sciences. Smell can present a more intelligent entry level, especially for uninitiated web declare online visitors, because there’s far less formalized language for describing smell than for decoding visible art or shows. Since there’s no “correct means” of talking about scent, she says, “your secure recordsdata is as perfect as the others’.”
Regardless of their doable to counterpoint our figuring out of historical past and art, smells are infrequently ever conserved with the same care as constructions or archaeological artifacts. But a exiguous group of researchers, including Strlič and Leemans, is attempting to substitute that—combining chemistry, ethnography, historical past and other disciplines to file and retain olfactory heritage.
A chemist might well theoretically whip up the smell of used books centuries from now.

Some tasks purpose to safeguard a cherished smell earlier than it disappears. When the library in London’s St. Paul’s Cathedral was once scheduled for renovation, to illustrate, Strlič and his UCL colleague Cecilia Bembibre put of abode about documenting the ancient library’s obvious smell.
The team first analyzed the chemical substances wafting from the assortment, which contains books dating support to the 12th century, and the surrounding furnishings, which maintain barely changed since the library was once performed in 1709. They former a course of known as gasoline chromatography-mass spectrometry, which helps separate, name and quantify volatile organic compounds, to depend on air samples they’d captured in the library.
“As an analytical chemist, I used to be once in a pronounce to list and quantify those molecules, nevertheless how of us describe what they felt required a fully diversified means,” says Strlič. To whittle down the list of compounds identified by the mass spectrometer to the ones that other individuals can actually smell, the researchers next invited seven untrained “sniffers” into the cathedral library and requested them to describe its smell using a listing of 21 adjectives continuously former to describe the compounds.

The list integrated phrases admire inexperienced and fatty, which of us most often spend to describe the smell of the chemical hexanal, and almond, which is associated with benzaldehyde. Every compounds are released by paper as it degrades. The sniffers were additionally invited to add any descriptors of their secure.
One observe that every person sniffers former to describe the library wasn’t particularly surprising: woody. Others that proved original were smoky, earthy, and vanilla. Such descriptors can abet conservators assess the pronounce of used paper, since papers which would be rather more acidic as a consequence of decay, to illustrate, “smell more sweet,” says Strlič. “And other individuals which would be stable smell more admire hay.”

Strlič and colleagues next matched the qualitative descriptors the sniffers had selected with their underlying chemical compounds to make a chemical “recipe” for the scent of the cathedral’s library. Such recipes are revealed in scientific journals and saved in digital overview repositories, so a chemist might well theoretically whip up the smell of used books centuries from now, “even if, in the future, of us no longer slide to a library or no longer read physical books, and handiest receive all recordsdata digitally,” says Strlič.
How feeble are mummies?
The work at St. Paul’s Cathedral, which ended in 2016, urged that it might possibly per chance well possibly be doable to capture far older scents—including smells from hundreds of years ago. For a deem revealed in 2025, Strlič was once joined by scientists from Egypt, Slovenia, Poland, and the United Kingdom to deem nine historical Egyptian mummies. The purpose was once to search out out about the mummification course of and recreate a scent that might be on hand to web declare online visitors of the Egyptian Museum in Cairo from 2026 onward.

One might well request the scent of millennia-used mummified our bodies to be off-putting, to converse the least. But the smell is surprisingly lovely, “because the historical Egyptians former so many aromatic compounds, oils and resins that plenty of the customary smell silent stays,” Strlič says.
To capture these chemical substances, Strlič and colleagues extracted air samples from the sarcophagi,
