The Old Masters market — a structured read

Old Masters painting combines historical expertise, material fact, provenance, and highly heterogeneous secondary venues. Serious analysis starts with transparent sources.

The takeaway

“Global” aggregates often hide quality and channel gaps. One school label can cover works whose prices are not comparable without strict methodological framing.

What Artmetria offers

The Artmetria Index and related datasets aim for comparability and traceability: what is included, what is excluded, and with what confidence.

Segment before you synthesise

Schools, centuries, sizes, condition: segmentation is not an academic detail — it is the condition for an interpretable average. Without it, aggregate curves can mix the incomparable.

The role of expertise

Attribution, school, circle: Old Masters depend heavily on literature and specialist opinion. Digital tools speed research; they do not replace the chain of evidence.

Secondary markets and heterogeneous lots

Specialist and regional sales play a real role in liquidity for some segments. Interpreting them requires knowing the houses, sale conditions, and typical catalogue quality.
