The form of this
lamp (wheelmade, short nozzle, evidence of attached
handle, traces of black slip?) suggests it is a great deal earlier than
Roman Cirta and is more likely to be an import from Greek colonies (or a local copy of them) in the
area during the 4th - 3rd Centuries BC.
Other details of the tomb (site construction, associated objects, etc.) would doubtless have revealed far more information but I suspect this was an unofficial "excavation" and anything not of monetary value was destroyed?
