This rimmed bronze disk has two ornamental fittings and rings attached to it. Images of the Shinto deities, who are enshrined in ten sanctuaries of Sannō shrine in Shiga prefecture are depicted on bronze plates by hammering them into the plates from the back and riveting them to the disk. This is the original set of images of which the Mandala of Sannō shrine is comprised. Rivets are visible on the back of the disk, and the name of each deity, whose image is attached with that rivet, is written next to each rivet in line carving; the names are Ōmiya
