## What you would see

A single, low oval vessel sits at the center of a plain studio setting, photographed slightly from above and from the side. The background fades from near-black at the top to dark gray below, meeting a smooth, lighter gray surface where the cup rests. The cup is wide and shallow, longer than it is tall, with gently sloping walls, a rounded body, and no clearly visible foot. Its rim is thin and uneven, with small chips and a faint crack-like line running along part of the edge. On the near side, a flattened, elongated projection extends along the wall like a worn handle; another low edge is suggested on the far side. The surface dominates the impression: mottled gray-green, beige, and dull stone tones, interrupted by reddish-brown patches near the rim and handle. It looks rough, pitted, powdery, and weathered, more like aged stone than glossy ceramic, though small variations hint at an original glaze. Soft light from above models the interior hollow and casts a short dark shadow to the right. No people, text, or scale reference appear, so its exact size cannot be judged from the image alone.

## How to look at it

Start with the elongated oval outline and notice how low and open the vessel is. Then look closely at the flattened protrusion on the side and the reddish, pitted patches: those details shift it from a simple bowl to an aged, handled object.

## Context

According to the source, this is an ear cup, or erbei, for wine, made by an unknown maker in China during the Han dynasty. It is dated 206 BCE–220 CE and catalogued by the Cleveland Museum of Art as lead-glazed earthenware in the Chinese Art department. Erbei are recognizable by their shallow oval shape and two small side projections, like ears, for holding. Many Han lead-glazed earthenwares survive with altered, muted surfaces after centuries of burial or aging, although the source does not say where this example was found or exactly how it was used.

## Curious detail

The name erbei is commonly understood as “ear cup,” referring to the two small ear-like handles that help identify this Han-dynasty cup form.

## Questions

- How does the weathered, stone-like surface change what you expect from an object made to hold wine?
- What might the small ear-like handles suggest about how this cup was held, passed, or shared?
- When an everyday vessel becomes this aged and fragile-looking, does it feel more like a tool, a relic, or a sculpture?

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