Timber trade in 17th-century Europe: different wood sources for artworks of Flemish painters.

The former Spanish Netherlands experienced a period of social, cultural and economic prosperity in the seventeenth century, with Antwerp as its most important commercial and artistic centre. The era's vibrant art scene, once pivotal culturally, economically, and diplomatically, now offers invaluable insights for scientific studies on art, trade, and craftsmanship. In a study on 294 panel paintings by or related to two famous Flemish artists, Jacques Jordaens (1593-1678) and Anthony van Dyck (1599-1641), we applied classical art historical techniques, archival research, dendrochronology, and the study of panel maker's and guild marks on the painting's reverse to gain insights into the precise time of tree felling, the geographical provenance of the wood, and the panel makers patronised by the painters. The majority of the paintings (~ 80%), which were subjected to a dendrochronological analysis, could be dated and the results accorded well with the concomitant art historical assessment on authorship. Besides an active and well-known Baltic timber trade which provided over 71% of all the planks examined, straight-grained oak trees were also sourced from western Central Europe (20%). Interestingly, planks from the Baltic and the Ardennes region (France/Belgium) were used together in three different paintings, likely cut apart from larger panels. Employing a multidisciplinary approach to a comprehensive painting collection by individual painters provides not only a new tool to determine a painting's date and authorship but also allows for a better understanding of the contemporary timber trade and associated craftsmanship.

Chronology and social significance of the "princely" barrow cemetery in Leki Male and the Central European Early Bronze Age.

The "princely" barrows of Leki Male, Greater Poland are the oldest such monuments within the distribution area of Únetice societies in Central Europe. While in the Circum-Harz group and in Silesia similar rich furnished graves under mounds have appeared as single monuments as early as 1950 BC, Leki Male represents a chain of barrows constructed between 2150 BC and 1800 BC. Of the original 14 mounds, only four were preserved well enough that their complex biographies can now be reconstructed. They included ritual activities (before, during, and after the funeral), and also subsequent incursions, including robberies. The long lasting barrow cemetery at Leki Male can be linked to a nearby fortified site, Bruszczewo. Together, Leki Male and Bruszczewo represent a stable, socially differentiated society that existed for no less than 350-400 years. Therefore, it can be argued that the Early Bronze Age societies of Greater Poland were extremely sustainable in comparison to those of other Únetice regions.
