## What you would see

The piece fills almost the entire frame, seen from above against a graduated background that shifts from black in the upper corners to gray below. It is a circular bronze disk, photographed from its back, with a slightly raised rim and a relief line marking an inner circle. Far from shiny, the surface has an uneven blue-green patina, with darker areas, turquoise flecks, small pits, scratches, and traces of corrosion that give it a rough, almost mineral texture. At the center rises a knob covered by a dense tuft of stiff coppery-brown fibers, like a hedgehog or a bristly pom-pom; it casts a short shadow to the right. Around it, in low and now worn relief, are two long-necked cranes with outspread wings, placed in opposite directions, one toward the upper left and the other below. Small blurred motifs surround them, resembling flowers, leaves, or birds, also in relief. Soft light emphasizes the edges and shows that the object is flat, thin, and intimate in scale, made to be held in the hand, although no human reference confirms its exact size.

## How to look at it

Start at the coppery tuft in the center, then follow the circle outward until you find the two cranes facing opposite directions. Look closely at the worn relief: the more blurred the small motifs become, the more the object reveals its age. Remember that the decorated side shown here is not the reflective one.

## Context

According to the source data, this is an unknown maker's bronze mirror from Japan's Muromachi period, dated broadly to 1392–1573. It belongs to the Cleveland Museum of Art's Japanese Art holdings and was a gift of D. Z. Norton. In premodern Japan, bronze mirrors typically had one polished, reflective face and a decorated back bearing auspicious designs. Cranes, or tsuru, are traditionally associated with longevity and good fortune, so a pair probably carried a wish for lasting happiness. It is not known who used this particular mirror, where exactly it was made, or how large its original cord was.

## Curious detail

What the photograph shows is the back of the mirror, not the reflecting surface; when new, the opposite polished bronze face would have served for seeing oneself.

## Questions

- Why decorate the side of a mirror that the person using it would not see while looking at their reflection?
- What changes in our reading of the object when we learn that its green surface was once polished bronze?
- What wishes or ideas might a pair of cranes have conveyed to whoever owned this mirror?

## Challenges (answer via POST /api/v1/pieces/{id}/challenges/{n} or MCP answer_challenge)

1. How many cranes in relief can you count around the central knob?
2. What color is the bristly tuft covering the knob at the center?
3. The mirror is circular, what geometric shape does the raised line at the inner border outline?
