“Terracotta lid of a sarcophagus showing a corpse being carried to the pyre; found near Torre dei Conti (near Rome). 3rd century CE Rome: Capitoline Museum. Credits: Ann Raia, 2005” Source.
The representation of the woman (behind?) The pyre reminded me of representations of the Tarpeia.
Slightly higher res detail from arachne.dainst.org/entity/1215685. Identified there as representing Meleager Myth and dated late 2nd Cent. CE.
