Past trade in oak from the lands to the east and south of the Baltic Sea was extraordinary in that it dominated the Northern European market for specialized oak products for many centuries. Equally extraordinary is the fact that since the 1980s, when a large corpus of dendrochronological data from artworks was demonstrated to represent the material evidence for this past trade, we, until now, have not been able to pinpoint where, in this large region, the trees for this trade grew. Through our analysis we can now present the likely sources of three major timber groups in this material, and significantly, the new chronologies that we make available here, will be the key foundation for dating and identifying provenance of Baltic oak, for tree-ring research long into the future.

过去波罗的海以东和以南的橡木贸易是非同寻常的，因为它在几个世纪以来一直主导着北欧专业橡木产品市场。同样非同寻常的事实是，自 1980 年代以来，当大量来自艺术品的树木年代学数据被证明代表了过去交易的物证时，我们直到现在都无法确定在这个大区域的什么地方，这种贸易的树木长大了。通过我们的分析，我们现在可以展示该材料中三个主要木材组的可能来源，并且重要的是，我们在此提供的新年表将成为确定波罗的海橡木来源的关键基础，用于树木年轮研究未来很长。
