Artmetria / Guide
A guide to schools and periods in painting
School labels help you navigate when they are read as historical and stylistic reference points — not as guarantees of value.
The takeaway
The market often reuses fuzzy terms: “circle of,” “follower of,” “manner of.” Behind each label, the range of quality and price can be huge.
What Artmetria offers
Internal taxonomy aims for coherent links between works, artists, and analytical segments. The Atelier extends that structure through pedagogy and looking exercises.
School, studio, influence
A “school” can mean a place, a lineage, a stylistic affinity — sometimes several at once. Precise vocabulary reduces mismatch between catalogues and readers.
Chronology and overlap
Centuries overlap; styles coexist. A clean chronology is a teaching tool; history is messier.
Reading a catalogue entry
Title, dimensions, medium, provenance: each line steers comparison. Knowing what to prioritise avoids comparing works that answer different questions.
