The item is a bronze oil lamp filler from the Late Roman or Byzantine periods, approximately 4th to 7th centuries AD. Use: These vessels were used to fill larger oil lamps (such as chandeliers) with oil, or were used as small oil lamps themselves. Design: They feature a round bowl, a long, shaped spout for precise pouring, and a decorative handle, sometimes in the shape of an animal or geometric shape. Material: Cast from bronze, which develops a patina (oxidation layer) in shades of green or brown over time.
