Evidence grades A–D
A = official or primary; B = corroborated; C = reasoned estimate; D = unverified. D is never used for buying decisions.
HOW THIS INDEX WORKS
Evidence, images, corrections and ads—
kept in view.
This index values traceability over the number of answers. Scope, confidence, image rights and update dates stay on the same page.
Four meaning types
Wearer, maker, contemporary reading and later reading remain separate. Compelling myths receive the clearest labels.
Image policy
Display only locally stored PD, CC0, CC BY, CC BY-SA or purchased material. Prefer authentic colour; never use AI colourisation as evidence. One image has one primary use by default.
Corrections
Changes to colour, date, place, motif or product status retain a reason and date. Earlier claims are not silently erased.
Advertising & affiliates
Commercial links are disclosed and ranking is not based on commission alone. Living products remain around 5% and are never inflated into historical association.
Participation & privacy
External submissions, voting and server-side boards launch only after moderation, deletion, consent and retention are designed. On-device bookmarks, recent pages and text-size settings are never sent to the server. Public measurement and owner diagnostics remain separate data classes.
PRIVACY-MINIMISED SESSION MEASUREMENT
You can switch off pseudonymous session measurement.
Browsing events are joined within a visit using a random session ID. The site does not store raw search terms, IP addresses, user-agent strings or email addresses as analytics data. This setting stays in this browser; while disabled, no new events are sent. Global Privacy Control and Do Not Track are also respected.

CORRECTION LOG
Corrections are part of the record.
Corrections before and after launch remain visible so the same mistake is not repeated. Superseded material that would violate privacy or rights is not republished.
- Replaced external-only culture links with full internal articles
Museum links now support the text as end sources rather than replacing it.
- Added an image-placement ledger
Each image receives one primary use; every exception reuse requires a reason.
- Corrected Highgrove colour from green to pink
The early colour record was corrected after rechecking the photograph and caption.
- Corrected star-and-moon to star print
Separated a later product name from the motif visible in the evidence photograph.
- Removed uncleared photography
Source links were retained while images without confirmed reuse rights were replaced by rights-safe diagrams.
