The Liuren earth plate: reading an incomplete object

01

Begin with what is missing

The National Museum identifies this object as part of a Liuren board and states that its heaven plate is missing. It then describes the general structure and operation of such boards. Keep the individual surviving object distinct from the general account.

Missing components limit direct observation. Separate what is visible, what the museum reports and what comparative evidence suggests. Label any later schematic as reconstruction or teaching illustration.

02

Make each reconstruction step explicit

Define whether the reconstruction concerns component relationships, spatial layout or a particular procedure. Identify the object evidence, textual rules and comparative objects used at each step. Keep their roles distinguishable in the resulting model.

In a digital model, attach a source and an uncertainty note to each component. When an assumption about the missing plate changes, record the affected display or calculation. This reveals how strongly the model depends on that assumption.

03

Write a concise reconstruction specification

Using only the museum page, make a boundary table: what survives, what is lost, what the page summarizes and what is still needed. Do not supply exact dates, dimensions or inscription details that the page does not provide.

Propose one follow-up task, such as finding a formal catalogue or plates of comparable objects. Explain which gap it addresses and how the evidence would change your record. Traceable evidence and revision make the work reviewable.
