10-08. Lazulite #1.
If this image looks to you as coming out of an early 20th century Eastern European or Viennese salon, you’re totally right! Lazulite, the crystal that inspired it was first discovered in Styria, Austria and the name comes from the German “Lazurstein”. That may also explain the “Weimar” kind of mood of the painting on the wall – the complex arrangement of the various atoms in a lazulite crystal.
Lazulite has a dipyramidal monoclinic crystal that comes as a massive block and is part of the P2 group symmetry. Next to Austria and Switzerland, it can be found today in Canada, Georgia, and Brazil.
Far from me to make a connection with Viennese waltz, but there is a distinct dancing feel in the way its unit cell structure holds its atoms together.
The background is a variation on one of Rober Allen’s design titled “Styrian red” and the resource comes from M. Lindberg and C. Christ – crystal structures of the lazulite.
