A closer look
Making, purchase and museum accession are different events. A late-thirteenth-century attribution and a 2005 accession date answer different questions. Keeping them separate makes the record clearer.
How to continue
Continue looking: write down visible details and keep interpretations in a separate column. Record viewing conditions, the photograph date and missing information. Revise when evidence changes, so the next reader can see what supported each judgement.
Scope: this is an editorial close reading. References support only the named collection examples or care principles, not authentication of shop stock or claims of religious efficacy.
