In Antiquity, a lamp was originally called a lychnus, from the Greek λυχνος, with the oldest Roman lamps dating back to the third century BC. It is thought that the Romans took the idea for lamps from the Greek colonies of Southern Italy. During the Roman Empire, it became commonplace to use lamps in funeral ceremonies and for public purposes. Closed oil lamps like this one enabled an oil-soaked wick to burn for an extended period of time with minimal smoke production. Multiple nozzles allowed for the insertion of numerous wicks simultaneously, and thus a brighter light source. This particular arch-shaped, multi-nozzle oil lamp is a unique design whose comparative examples seem to originate in the Eastern provinces of the Roman or Byzantine empires.
