The results showed that the age of the wood was too late for any of them to have been painted by Hieronymus Bosch.
While dendrochronology has become an important tool for dating oak panels, it is not effective in dating the poplar panels often used by Italian painters because of the erratic growth rings in poplar. The sixteenth century saw a gradual replacement of wooden panels by canvas as the support for paintings, which means the technique is less often applicable to later paintings. The dating of buildings with wooden structures and components is also done by dendrochronology; dendroarchaeology is the term for the application of dendrochronology in archaeology.
While archaeologists can date wood and when it was felled, it may be difficult to definitively determine the age of a building or structure in which the wood was used; the wood could have been reused from an older structure, may have been felled and left for many years before use, or could have been used to replace a damaged piece of wood.
The dating of building via dendrochronology thus requires knowledge of the history of building technology. Herbchronology is the analysis of annual growth rings or simply annual rings in the secondary root xylem of perennial herbaceous plants.
Similar seasonal patterns also occur in ice cores and in varves layers of sediment deposition in a lake, river, or sea bed. The deposition pattern in the core will vary for a frozen-over lake versus an ice-free lake, and with the fineness of the sediment.
Sclerochronology is the study of algae deposits. Some columnar cacti also exhibit similar seasonal patterns in the isotopes of carbon and oxygen in their spines acanthochronology. These are used for dating in a manner similar to dendrochronology, and such techniques are used in combination with dendrochronology, to plug gaps and to extend the range of the seasonal data available to archaeologists and paleoclimatologists. A similar technique is used to estimate the age of fish stocks through the analysis of growth rings in the otolith bones.
