On the blue and green pigments of post-Byzantine Greek icons

In the framework of a large-scale investigation of post-1453 ce icons, the blue and green pigments on more than 50 works were investigated. Studied works date from the mid-15th to the mid-19th centuries and originate from various modern-day Greek regions. Results indicate the use of both natural and artificial pigments; among the latter, the very poorly documented in Greek icons artificial Cu-based blue is included. A shift as regards the use of specific pigments is reported and local trends are compared with the contemporary Western European ones. Relevant terms found in the renowned Hermeneia craftsman's handbook are also discussed in an attempt to restore pertinent misconceptions.
