## What you would see

Centered against a soft graduated gray background, a large globular stoneware jar dominates the frame with its low, broad and sturdy form. Its profile swells into full rounded shoulders and a bulbous belly that tapers gently toward a small foot and a short, straight neck with a wide, slightly flared mouth. The surface is coated in a glossy iron glaze in a muted olive-green with grayish and yellowish-brown undertones, paler and more worn near the base where the glaze thins. The entire body is covered with dense, shallow impressed and combed decoration: horizontal bands of interlocking diamonds, hatched triangles, zigzags and fine parallel lines that create a textile-like texture visible on close inspection. Around the shoulder, four small applied lug handles in the form of stylized beast masks holding a ring protrude symmetrically, adding subtle three-dimensional relief. A strong highlight gleams on the right side while a deep shadow falls to the left, emphasizing the glaze’s fine crackle, minor chips, pitting and the slightly uneven handmade wall. The scale feels substantial, suggesting a storage or funerary vessel meant to be both functional and impressive up close.

## How to look at it

Start with the generous rounded silhouette and the glossy olive glaze, then trace the fine geometric bands wrapping the belly. Linger on the four small mask-and-ring lugs on the shoulder — their tiny sculpted faces interrupt the pattern and reveal the maker’s touch.

## Context

According to source data from the Cleveland Museum of Art, this is a Proto-Yue ware jar dated to 265–317 CE, attributed to China during the Western Jin dynasty (265–316 CE). It is described as gray stoneware with combed, impressed, molded and applied decoration under an iron glaze, typical of southern Chinese kilns that preceded classic Yue celadon. The maker is unknown, as is common for workshop ceramics of this period. No specific archaeological findspot is given. Such large patterned jars are generally associated with elite daily use and burial assemblages during this era of political division following the Han dynasty.

## Curious detail

Proto-Yue ware is regarded as the direct predecessor of Yue celadon, one of the most celebrated glazes in Chinese history, already achieving its soft green color through iron oxide fired in a reducing kiln atmosphere.

## Questions

- How does the dense geometric patterning interact with the smooth, swelling form of the jar?
- Why might a functional storage vessel be given such elaborate decoration and symbolic mask handles?
- How does knowing the jar is over 1,700 years old affect the way you see its preserved shine and wear?

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

1. Look carefully: how many mask-and-ring handles stick out around the shoulder of the jar?
2. What tone is the glossy glaze covering the jar that comes before classic celadon?
3. What kind of decoration covers the belly of the jar forming almost textile-like bands?
