This type of lamp was found in strata associated with Herod's reign (37-4 B.C.E.). A similar lamp was uncovered in the Jewish Quarter of Jerusalem, in strata dating to the destruction of the Second Temple (70 C.E.).
Characteristic features of this lamp type are a circular wheel-made body, a flat unmarked base, and a large central filling hole. The spatulate nozzle was hand-built and attached separately. Traces of a palm-fiber wick were found in the lamp's nozzle.
