This study addresses the provenance of two Roman river barges and a Roman punt excavated along the limes of Germania inferior near the Dutch city of Utrecht ( De Meern 1 , 4 and 6 ). To establish the geographical origin of these vessels, their tree-ring series are compared to 1452 dated oak ( Quercus robur/petraea ) growth patterns from Roman-period sites in the current Netherlands and Belgium. The strong resemblance to patterns of oak used in the civitas Menapiorum and the bordering region of civitas Nerviorum in Gallia Belgica indicates that the ships were built with oak from the lower-Scheldt region in present-day Flanders (north-western Belgium). Given the absence of Flemish oak in Roman land-based constructions along the Dutch limes , this provenance implies that the vessels were constructed in the lower-Scheldt region. The geographical location of the final wreck sites of De Meern 1 , 4 and 6 points at inland-navigation between this region and the Rhine-based limes of Germania inferior . [ABSTRACT FROM AUTHOR]

Abstract: To analyse fuelwood collection strategies in Roman funerary rituals in northern Gaul, a large number of charcoal fragments from Roman cremation graves has been identified. The wide variety of taxa found suggests that no particular taxa have been avoided. Also no significant differences have been found between the charcoal assemblages of different types of graves and between graves belonging to different types of settlements. On the other hand, comparison with the charcoal assemblages from Roman refuse deposits, reflecting domestic fuel use, shows an overrepresentation of Quercus sp., Alnus sp. and Fagus sylvatica, and a much lower taxonomic variety in the cremation graves. This is believed to be the consequence of functional rather than ritually or symbolically oriented fuelwood selection strategies. [Copyright &y& Elsevier]

Abstract: We overview the recent development of oak dendrochronology in Europe related to archaeology and art-history. Tree-ring series of European oaks (Quercus robur and Q. petraea) have provided a reliable framework for chronometric dating and reconstruction of past climate and environment. To date, long oak chronologies cover almost the entire Holocene, up to 8480 BC and the network over the entire area in which the two oaks grow is being improved. We present the main characteristics of oak ring series and discuss the latest methodological advances in defining the calendar year in which the tree-rings were formed and in interpreting such dating in terms of the age of a wooden object. Dendrochronology has established itself as a standard dating tool and has been applied in a wide variety of (pre-)historical studies. Archaeological wood, historical buildings, works of art (such as panel paintings and sculptures) have been successfully investigated. Recent advances in dendro-provenancing have helped to obtain more information on the timber trade in the past. Information on past forest structures, silviculture and timber use have become available through scrutinizing historical and contemporary ring-width patterns. [Copyright &y& Elsevier]

Abstract Variations in building activity reflect demographic, economic and social change during history. Tens of thousands of wooden constructions in Europe have been dendrochronologically dated in recent decades. We use the annually precise evidence from a unique dataset of 49 640 tree felling dates of historical constructions to reconstruct temporal changes in building activity between 1250 and 1699 CE across a large part of western and central Europe largely corresponding to the former Holy Roman Empire of the German Nation. Comparison with annual records of 9772 plague outbreaks shows that construction activity was significantly negatively correlated to the number of plague outbreaks, with the greatest decrease in construction following the larger outbreaks by three to four years after the start of the epidemics. Preceding the Black Death (1346–1353 CE) by five decades and the Great Famine (1315–1322 CE) by two decades, a significant decline in construction activity at c. 1300 CE is indicative of a societal crisis, associated with population stagnation or decline. Another dramatic decline in building activity coincides with the Thirty Years' War (1618–1648 CE) and confirms the devastating nature of this conflict. While construction activity was significantly lower during periods of high grain prices, no statistically robust relationship between the number of felling dates and past temperature or hydroclimate variations is found. This study demonstrates the value of dendrochronological felling dates as an indicator for times of crisis and prosperity during periods when documentary evidence is limited. Highlights • Reconstructing European building activity 1250–1699 CE from 49 640 tree felling dates. • Lower building activity coincided with more plague outbreaks and higher grain prices. • Reduced building activity during the Late Medieval Crisis (c. 1300–1415 CE). • Unprecedented decline in European building activity during the Thirty Years' War.

Abstract: Archaeological research of shipwrecks mainly focusses on both the study of the general structure and the individual timber elements and on the provenancing of ships by dendrochronological analyses and the study of the cargo. This study now presents the analyses of a large number of samples from the mosses that have been used for the caulking of two early 14th century maritime cargo vessels. The identification of the mosses showed that different taxa have been used for the caulking of original seams, repairs and for re-caulked seams. Analyses of the botanical macroremains of vascular plants trapped in these mosses confirm the different environments these mosses have been collected in, as is suggested by the ecological characteristics of the different identified taxa. The analyses of pollen trapped in these mosses indicate a different regional origin of the mosses used within one single ship and thus show the potential of this technique for the provenancing of shipwrecks and ancient ship routes.
