## What you would see

What is shown is the reverse side of a circular bronze mirror, photographed frontally against a gradient background that fades from black to light gray, emphasizing its silhouette. The edge is not a perfect circle but lobed, shaped like an eight-petaled flower with soft undulations, creating a scalloped outline. The surface is covered with a mottled patina in bluish-green, brownish and grayish tones, with a rough, corroded texture and encrustations that reveal its age. At the center stands out a dense tuft of reddish-brown fibers, like a small tassel, corresponding to the cord used to hold the mirror. Around it, a very worn low relief can be glimpsed: a circular band and inner scenes with vegetal forms, cloud-like shapes and perhaps birds or mythical animals, now almost erased by time. Frontal and diffused light accentuates the eroded volumes and the irregularities of the metal, casting soft shadows in the hollows of the relief and revealing small whitish spots of corrosion and darker areas where the patina is deeper. The overall scale suggests a handheld object, intimate yet richly worked, where even the decay has become part of its beauty.

## How to look at it

First notice the lobed edge that breaks the perfect circle and suggests a flower. Then move your gaze to the reddish tuft at the center and slowly trace the worn relief outward to see how time has softened the figures. Pay attention to how the greenish patina and rough texture shift with the light and tell the story of its age.

## Context

This is a bronze mirror attributed to Japan's Heian period, between 794 and 1185, according to data from the Cleveland Museum of Art where it is held in the Japanese Art department. The maker is unknown, as is common for metalwork of this era. Bronze mirrors, known as kyō in Japanese, were used for both daily and ritual purposes, and their backs were often decorated with auspicious, floral or Chinese-inspired motifs. The technique is cast bronze. The source provides no detailed description of the iconography, so its exact place of manufacture within Japan and the precise meaning of its decoration are not known. It was probably part of a personal trousseau or a temple offering.

## Curious detail

In Japan bronze mirrors were not only toiletry objects but also sacred treasures in Shinto, associated with the sun goddess Amaterasu, and were frequently deposited as offerings at shrines and temples.

## Questions

- How does your reading of the object change when you realize the decorated side is the non-reflective one?
- What does the wear and patina make you feel about age, beauty and the value of imperfect things?
