A multi-analytical approach using FTIR, GC/MS and Py-GC/MS revealed early evidence of embalming practices in Roman catacombs

Chemical characterization of the amorphous samples was achieved using FTIR spectroscopy and gas chromatography/mass spectrometry (Py-GC/MS and GC/MS) and by comparison with reference samples from known origin. This allowed for the unambiguous identification of precious and exotic resinous substances involved in the embalming process of the bodies. Amber, sandarac and frankincense, which were sourced from widespread locations, were used as part of the funerary treatment. This first evidence of such highly prized commodities in burial process provides us with new insight into funerary practices as well as commercial networks in the Roman Empire during the first centuries A.D.
