SUMMARY:Prof. Eric Dooryhée\, CNRS\, Grenoble
TZID:Europe/London
UID:20090429-094d43f61e456bff011ed4943bdb10f6@warwick.ac.uk

DESCRIPTION:Crystallography in Art and Archaeology The regular\, and some
 times complex\, arrangement of atoms and molecules in a crystal has alwa
 ys had a naturally artistic appearance. Subdivisions of 2D or 3D space u
 sing crystal-like shapes\, repeated patterns\, symmetry groups and cryst
 allographic rules have been and still are a source of profound inspirati
 on for many artists. Symmetry\, or the lack of symmetry\, has been a cen
 tral concept in science since ancient times\, and prevails in various fi
 elds of art such as painting\, sculpture\, architecture\, music\, dance\
 , poetry. In the first part of the talk\, various examples and illustrat
 ions will show how the formal qualities of a work of art intersects the 
 basics of crystallography. The talk will also cover the recent implement
 ation of crystallographic methods to address enigmas in archaeology and 
 art such as the identification and provenance of materials\, the trade r
 outes\, the elaboration procedures and the artists' know-how. Other issu
 es are concerned with the authentication\, transformation and preservati
 on of artefacts. The history of these objects\, as part of our cultural 
 heritage\, is often embedded in the structure and micro-structure of the
  component materials\, and such fingerprints need to be deciphered every
  time ancient texts are silent or absent.
