Greek and Egyptian lamps that date before the third century BC were typically wheel made. Characteristically, they have a simplistic structure with little to no ornamentation. A wide pour hole is often found to fill their discus area. Lugs (ears) were commonly attached to the shoulders for both practical and aesthetic purposes. Pierced lugs surfaced briefly between the fourth and third centuries BC on lamps without handles. Bailey argues they had allowed the lamp to be hung when not in use, and were positioned so that the oil could not leak out through the nozzle. Unpierced lugs were purely decorative and used well into the first century BC.
