Three Pillars of Art Authentication: Connoisseurship, Technical Analysis, Provenance

Art authentication relies on three main tools: connoisseurship, technical analysis, and provenance research. Connoisseurship, emerging in the late 17th century, involves recognizing artistic characteristics through visual memory and cross-referencing. Technical analysis examines materials like pigments, canvas weaves, wood panels via dendrochronology, and paint layers to date and attribute works. Provenance research traces ownership history through archival documents such as contracts and inventories. These tools help identify counterfeits, distinguish masters from workshop pieces, and uncover problematic pasts like Nazi looting or colonial plunder. Museums increasingly rely on provenance to contextualize and potentially restitute works. The process combines skills from history, chemistry, and art production. Universities now offer specializations in these areas, and technology continues to evolve the field.
