Read the impression. Recover the context.

Begin with what survived.

A seal seems to offer an unusually direct encounter with the past. Somebody pressed a design into a material, and here is the result. But an impression, its matrix, its mount, a document, and a museum photograph are different things. Their relationship is exactly what the researcher needs to establish.

The National Archives’ research guide distinguishes the engraved matrix from the impression and explains seals’ use in authenticating documents. It also describes how a seal could be attached. That is a starting point for documentary research, not a guarantee that every detached impression identifies its original document or its user.

Our wax example is catalogued with a broad date range and a qualified cultural attribution. The bronze matrix is catalogued as later manufacture in a medieval style. Its photograph includes an accompanying impression, whose separate date and material are not established here. Preserve those differences before comparing the images.

Give each witness its own record.

The distinction matters even when all five records eventually agree. Agreement must be demonstrated; it cannot be supplied by putting everything into one confident caption. Leave a blank field where the witness has not been found.

✦ Try the claim audit

What supports the sentence?

For each proposed claim, identify its strongest basis: an observation in the supplied photograph, a statement attributed to the catalogue, a proposal for further research, or a claim not established by the available evidence. Write one sentence explaining your choice before opening the discussion. Some unsupported claims also conflict with what the catalogue actually says.

1. The wax impression shows a shield below a helmet and ornament.

   Discuss the evidence

   Photograph-based observation. The arrangement can be inspected in the photograph. This describes visible forms without supplying a complete blazon or identifying their bearer.

2. The field of the arms is Sable because the wax is black.

   Discuss the evidence

   Not established. The dark material carries the field and its device alike. Its colour does not distinguish their tinctures. You would need a securely connected colour witness, written blazon, or applicable notation.

3. The museum’s date range for the impression is 12th–16th century.

   Discuss the evidence

   Catalogue statement. This reports the linked date field. The photograph alone does not demonstrate the range, and the range does not identify a precise sealing event.

4. The bronze matrix was made in the thirteenth century.

   Discuss the evidence

   Not established; conflicts with the catalogue. The catalogue assigns nineteenth- or twentieth-century manufacture and a thirteenth-century style. The proposed sentence replaces the manufacture date with its stylistic reference.

5. The two forms in the matrix photograph have reversed arrangements.

   Discuss the evidence

   Photograph-based observation. Compare the figure, the small animal above it, and the lettering. This comparison does not independently date the orange impression or establish its material.

6. The matrix was intentionally made to deceive a medieval-seal collector.

   Discuss the evidence

   Not established. Later manufacture does not establish deceptive intent. Production or sale records, a false representation, and evidence about the intended audience would be needed. The catalogue date does not supply those facts.

7. An earlier acquisition record might help explain the writing on the wax impression’s mount.

   Discuss the evidence

   Research proposal. This names a source to investigate and a question it might answer. It is not a report that the record has been found or that it identifies the bearer. The proposed search could produce no answer.

8. Both objects demonstrate the same family’s medieval entitlement to arms.

   Discuss the evidence

   Not established. This combines an unidentified armorial impression with a later pictorial matrix. No shared family, corresponding design, medieval use of the matrix, or entitlement record has been established in these studies.
