Reliquary in the shape of a coffin

Reliquary in the shape of a coffin by unknown artist. The object is a small, rectangular box with a curved top, resembling a miniature coffin. It is made of dark metal, possibly bronze or copper, with a weathered and worn appearance. The surface features intricate etchings and engravings, including swirling patterns on the top and a raised panel on the front. The panel on the front appears to have a recessed area with two circular indentations. The box sits on a stepped base, with a flat bottom and a slightly raised edge around the perimeter. The background of the image is a plain gray color, allowing the object to be the focal point.
