How do I identify a seventeenth-century piece?

Examine the preparation of the support, the garment styles such as ruff collars, and the pigment composition under magnification. Compare the handling of light and facial modeling against authenticated examples from the same regional school.

Are these works painted on canvas or wood?

Surviving examples appear on both traditional stretched canvas and rigid wooden panels. Panel supports frequently indicate earlier northern European origins, while canvas became increasingly widespread over time.

What is the difference between an original and a later copy?

Seventeenth-century originals display contemporary pigments and organic ageing patterns consistent with their stated period. Later copies executed in nineteenth-century or twentieth-century revivals often reveal modern priming layers and mechanical surface textures.

How should I care for an antique oil painting?

Keep the artwork away from direct sunlight, heating vents, and damp environments to protect the organic canvas or wood. Avoid chemical cleaning agents and consult a professional conservator for surface maintenance or varnish removal.
