|Joy to All Who Suffer, c. 1750|
For those of you in the Boston area (or will be by February 2, 2013), here's an exhibition of Russian Orthodox icons that you might want to check out, at the The Museum of Russian Icons. The show's description states:
The great masters of iconography developed the use of symbolism to depict otherworldly beings and imprecise subjects such as angels, demons, prayer, and wisdom. Over time, these developed into beautiful and sometimes mysterious images.
