Wood from antiquity has been preserved in certain situations such
as air-tight conditions, or dryness. Dendrochronology is the method
with which the date when a tree was felled can be determined. In
the best cases, the exact date can be calculated based on the
different spaces between the tree rings.
After these spaces have been measured using a microscope, a graphic is prepared that is then compared with the tree-ring calendar. The examples in the Roman exhibit in Wörth were parts of a wooden beam and of a tree trunk that had not been worked on.
