Ashes from Pompeii: incense burners, residue analyses and domestic cult practices

Incense burners are frequently excavated at Roman period sites, attesting to acts of combustion within domestic ritual practices, but what was burnt is still uncertain. Here, the authors use microscopy and spectrometry to analyse burnt residues contained within two censers from domestic contexts in Pompeii and a nearby villa . Their results indicate that woody plants were burnt in both censers, either as fuel or offerings, alongside stone fruit or laurel plants and possibly wine or grapes, while traces of Burseraceae resins, originating from Asia or sub-Saharan Africa, provide the first archaeological evidence of incense offerings in the Pompeian domestic cult.
