Summary

We present the application of dendrochronological dating of the renovation and construction works of churches in the Kaunas and Vilnius regions of Lithuania. The model for the estimation of the missing rings of Scots pine was used in Lithuania for the first time. We have assessed 18 timber cross-sections from nine churches, which were used for the constructions from the second half of the 17th to 19th c. The oldest wood samples were dated from St. Michael’s Church in Vilnius (1668±4) and St. George, the Martyr, (Bernardine) Church in Kaunas (1693±3). The aim of this study was to compare the results of the investigation of timber samples from 9 churches with archival sources and literature data and to reveal the renovation history of the buildings. The study of written historical sources has revealed a lack of recorded building and reconstruction phases of the churches. This fact was later confirmed by the results of dendrochronological dating. The dating of the timber revealed undocumented reconstruction dates in Zapyškis church (1791±3), St. George, the Martyr, (Bernardine) Church in Kaunas (1711±4), St. Anne Church in Skaruliai (1693±3) and Vilnius Cathedral (1814±4).

Abstract

Sub-fossil oaks from Smarhoń in Belarus have been investigated and tree-ring chronologies were assembled. According to radiocarbon dating, the oldest oak grew from 5782–5612 cal BC and the youngest from 1575–1747 cal AD. Radiocarbon and dendrochronological dating of 97 samples, four single series, 10 mean curves (containing 2–9 series) and three chronologies (10–25 series) were constructed. The longest chronology (No. 16), covering 549 years, was absolutely dated against various oak chronologies of Polish/Baltic origin to AD 778–1326. Germination and dying-off phases were assessed from the three best replicated chronologies. A spectral analysis of the chronologies provided cycles of variable length, on average of 25 years.
