Indian Yellow and Titanium White : A Material-centred Perspective on the Pigments Used by Artists Helene Schjerfbeck and Akseli Gallen-Kallela in the…
2022
This article presents the results of material studies focused on identifying and comparing the contents of the pigment palettes of two notable Finnish painters, Helene Schjerfbeck (1862–1946) and Akseli Gallen-Kallela (1865–1931). The research methods used comprise energydispersive X-ray fluorescence spectrometry (EDXRF) and polarised light microscopy (PLM). In addition, certain pigments have been identified in colour areas of the works using specular reflection FT-infrared spectrometry (FTIR) and Raman spectrometry. To support the results gathered using scientific analytical methods, archival research has been conducted in order to find notes and references to the pigments made by the arti…

Long-term changes in pigmentation of arctic Daphnia provide potential for reconstructing aquatic UV exposure
2016
Abstract Despite the biologically damaging impacts of solar ultraviolet radiation (UV) in nature, little is known about its natural variability, forcing mechanisms, and long-term effects on ecosystems and organisms. Arctic zooplankton, for example the aquatic keystone genus Daphnia (Crustacea, Cladocera) responds to biologically damaging UV by utilizing photoprotective strategies, including pigmentation. We examined the preservation and content of UV-screening pigments in fossil Daphnia remains (ephippia) in two arctic lake sediment cores from Cornwallis Island (Lake R1), Canada, and Spitsbergen (Lake Fugledammen), Svalbard. The aims were to document changes in the degree of UV-protective p…
Porc et sanglier en Gaule septentrionale, entre archéozoologie et imaginaire collectif
2006
In France, when we speak about the animal associated to celtic people, everybody thinks and mentions wildboar. This topic meanly emerged from XIXe historiography, but Archaeozoology shows that this animal is very rare in every kinds of sites (settelments, shrines or cemeteries). In other hand, the excavations of these sites give a great amount of pig bones, this animal is in fact one of the more important in celtic husbandry and meat production. The aim of this paper is to illustrate the difference between historiographic and archaeological evidences.
