Klimt artwork: red-pigment material investigation by backscattering Fe-57 Mössbauer spectroscopy, SEM and p-XRF
2017
Material tests were performed on a rediscovered Klimt-artwork "Trompetender Putto". We performed studies on the red colored spots, mainly taken from non-restored parts. MIMOS II Fe-57 Mossbauer spectroscopy (novelty in art-pigment analysis) mainly reveals haematite and crystallized goethite in red colors. Electron microscopy can identify various layers of the original and overpainting of an artwork. The number of layers fluctuates between three and four chemically painted areas. The portable X-ray fluorescence analysis enables to reduce the pigment list to containing mercury (cinnabar), lead, zinc, iron and titanium. Infrared-light-irradiation visualizes the different age of the pigments.
Digital Art History at the Crossroads
2022
Information and Communications Technologies, and more specifically online digital media, are revolutionizing the ways to produce and disseminate scientific knowledge. Humanities and social sciences -art history among them- are not alien to this process. The new challenges and opportunities have already generated a body of thinking and abundant case studies. Many of these applications have been exploratory, disconnected, and short-lived, but nonetheless very stimulating. This essay offers a report on the state of the conversation: a meeting at the crossroads, briefly outlining debates, agreements and disagreements, (dis)continuities with the broader framework of the discipline, and future pe…
Grenzen
2019
„Wo, wie, warum ziehen wir unsere Grenzen?“ Diese Fragen beziehen sich nicht nur auf physisch begehbare Räume und administrativ handhabbar gemachte Einheiten. Grenzziehungen und Entgrenzungen sind immer auch Ausdruck von Machtansprüchen, von politischer, sozialer und individueller Identitätssuche, von menschlicher Selbstdefinition. Denn wenngleich es Grenzen zwar von jeher gegeben zu haben scheint, entsteht doch der Eindruck, dass sie in der modernen Realität zunehmend bedeutsamer werden, obwohl oder gerade weil sie allenthalben fallen: Nicht zuletzt Anfang und Ende menschlichen Lebens werfen die Frage nach der Grenze, ihrer Definition, ihrer Verschiebbarkeit auf. Tatsächlich ist das Wort ‚…
