How Teresa and Maria Margaretha migrated to Nordstrand: Translation of Relics and Transformation of a German Island into a Catholic Dutch enclave in the 17th century

When on 26 May 1662 the founding first stone was laid for a new church on the island Nordstrand at the coast of Schleswig, relics of Teresa of Avila (1515-1582) and of the Dutch Carmelite abbess Maria Margaretha ab Angelis (1605-1658) were inserted. This church was built for Dutch dyke builders who were called to reconstruct the island after its destruction by flood in 1634; coming from a Catholic background and from the Dutch Republic which was at war with Spain at that time, the dyke builders and their families were guaranteed religious freedom in the Lutheran duchy of Holstein. In this paper, the reasons for the choice for the Spanish mystic Teresa of Avila and for the Dutch Carmelite abbess Maria Margaretha are discussed. The latter patroness was never beatified but had died in the smell of holiness; after her death several miracles were ascribed to her. It is understandable that migrants brought relics of their appreciated holy persons who would remind them of their homeland. The paper will first shortly introduce the two patronesses of the church. In the second part, the reasons for this choice will be discussed. Behind this translation of relics not only spiritual reasons played a role. The function of the translation of the saints was first to keep up geographical and political connections with the old country (both Spain and the Netherlands), secondly to perpetuate personal-familial relationships (esp. with Maria Margaretha), thirdly to strengthen the confessional identity in a non-Catholic environment. Fourthly the transfer brought a certain model of Christian life and reform to the new place of living, which in the second part of the 17th century became marked as “Jansenist”. The paper shows the transformation of the island into an enclave of Dutch Catholic culture.

Exploring Growth Variability and Crown Vitality of Sessile Oak (Quercus Petraea) in the Czech Republic

Unraveling climatic effects on growth of oak - Europe’s most ecologically and economically important forest species - has been the subject of many recent studies; however, more insight based on field data is necessary to better understand the relationship between climate and tree growth and to adapt forest management strategies to future climate change. In this report, we explore the influence of temperature, precipitation and drought variability on the productivity and vitality of oak stands in the Czech Highlands. We collected 180 cores from mature oaks (Quercus petraea) at four forest stands in the Czech Drahany Highlands. Standard dendromethods were used for sample preparation, ring width measurements, cross-dating, chronology development, and the assessment of growth-climate response patterns. Crown vitality was also evaluated, using the modified ICP Forests methodology. Late spring precipitation totals between May and June as well as the mean July temperature for the year of ring formation were found to be the most important factors for oak growth, whereas crown condition was significantly affected by spring and summer drought. This study is rep-resentative for similar bio-ecological habitats across Central Europe and can serve as a dendroclima-tological blueprint for earlier periods for which detailed meteorological information is missing .

Long-term summer temperature variations in the Pyrenees from detrended stable carbon isotopes

Substantial effort has recently been put into the development of climate reconstructions from tree-ring stable carbon isotopes, though the interpretation of long-term trends retained in such timeseries remains challenging. Here we use detrended δ13C measurements in Pinus uncinata tree-rings, from the Spanish Pyrenees, to reconstruct decadal variations in summer temperature back to the 13th century. The June-August temperature signal of this reconstruction is attributed using decadally as well as annually resolved, 20th century δ13C data. Results indicate that late 20th century warming has not been unique within the context of the past 750 years. Our reconstruction contains greater am-plitude than previous reconstructions derived from traditional tree-ring density data, and describes particularly cool conditions during the late 19th century. Some of these differences, including early warm periods in the 14th and 17th centuries, have been retained via δ13C timeseries detrending - a novel approach in tree-ring stable isotope chronology development. The overall reduced variance in earlier studies points to an underestimation of pre-instrumental summer temperature variability de-rived from traditional tree-ring parameters.
