Western-Han Bronze Lamp with Inscription of “Shang Yu”

This bronze lamp has a round base, a plate-shaped top, and a tube-like connector featuring two line patterns, and a bump in the shape of garlic bulbs in the middle. A cone-shaped wick lies in the center of the 2.5 cm-deep plate, on the exterior side of which there is an inscription of “Shang Yu Ming Jiasi”, meaning an official in charge of bath ware named Jiasi.
