# Silence and Argument Are Not the Same Gap
> This archive grades 1,797 ownership links. 271 are marked unknown and 160 disputed, and the two do not fall on the same objects. Printed books carry twelve unknown links and not one disputed link in the whole class.

## Key points
- This archive grades every ownership link. Across 257 published records there are 1,797 of them: 1,366 documented, 271 unknown and 160 disputed.
- The two failures fall on different objects. 200 records carry at least one unknown link and 99 carry at least one disputed link; 72 carry both and 30 carry neither.
- Dispute tracks fame and value rather than evidence. Printed books carry 61 links of which 12 are unknown and none at all are disputed; prints, photographs and furniture carry one disputed link each across 209 links between them.
- Arms and armour runs the other way, with 19 of its 88 links disputed, the highest rate in the corpus. Nobody argues about a Georgian bookcase because nothing turns on the answer.
- An object can date itself precisely and still have no ownership history. The Blacas Ewer gives its maker and the month of its making and then goes unrecorded until 1866.
- A disputed link often means the only witness was selling. The prior ownership of the David Vases before Charles Russell rests on a story relayed through a dealer, and it could not be verified when it was first reported.
## An archive can fail to know something in two completely different ways
## Of 1,797 links, 271 are unknown and 160 are disputed
## Where nobody argues, it is usually because nothing turns on the answer
## An object can name its maker and the month, and still have no owners
## A disputed link often means the only witness was selling
## Two parties can give different accounts of the same afternoon
## The buyer at the sale is a routine unknown
## How to read the two grades
## Why this archive is free to read
A chain with no disputes in it is not a clean chain, and this archive can now show why: the classes nobody argues about are among the least documented we hold. Silence and argument are separate failures with separate cures, and a record that runs them together as uncertainty hands its reader the one thing a provenance is supposed to remove.
## Questions
**What is the difference between an unknown and a disputed provenance link?**
Unknown means no record of the step has been found, so closing it requires archival research. Disputed means records exist but disagree, or the only account comes from an interested party, so closing it requires weighing evidence rather than finding more of it.
**How much of this archive's provenance is documented?**
1,366 of 1,797 graded ownership links, about 76 per cent, are documented. 271 are unknown and 160 disputed. Only 30 of the 257 published records have a chain in which every single link is documented.
**Which objects have the most disputed ownership?**
Arms and armour, with 19 of 88 links disputed, followed by antiquities and sculpture. These are classes where a famous former owner or wearer adds value that the physical object cannot itself confirm.
**Why do printed books have no disputed provenance links at all?**
Because a printed book is a multiple, so the identity of an individual copy rarely carries a name worth contesting. Its 61 links include 12 unknown ones, which shows the absence of dispute reflects a lack of stakes rather than better documentation.
**Can an object be precisely dated and still have no known owners?**
Yes, and it is common in medieval Islamic metalwork. The Blacas Ewer names its maker and dates itself to April 1232, and its recorded ownership does not begin until the British Museum acquired the Duc de Blacas collection in 1866.
