Dendrochronology is a comparative analysis technique that, among other things, allows for dating and authenticating wooden objects through the study of tree rings.
This technique is used in art diagnostics as well as in restoration operations for artworks that present a wooden support; a panel can thus be dated through the study of its rings when they are sufficiently numerous and discernible.
The process begins with a meticulous analysis of the growth rings: by examining the width, density, and color variations of these rings, it is possible to establish a distinct pattern, a kind of unique fingerprint, which corresponds to specific chronological periods. This data is then cross-referenced with existing tree-ring chronologies, providing an accurate timeframe during which the tree was cut.
With the continuous advancement of technology, the applications and precision of dendrochronology in the field of art are bound to expand, opening new avenues for exploration and discovery at the intricate intersection of science and art.
