Baltic timber in Western Europe - An exciting dendrochronological question

During the Middle Ages and early modern times timber became one of the most important commercial products. Vast quantities were transported from the ports of the Eastern Baltic Sea to Western Europe and used among other things as the panels for paintings. A growing number of very local master chronologies constructed in Poland for oak (Quercus spp.) increases the possibility to localize its origin. Using methods of so-called dendroprovenancing, timbers from Bialowieza Forest in Eastern Poland, for example, were detected in a Scottish castle. However, the question of Baltic timber in historic objects of Western Europe still remains an exiting challenge.
