Icons reworked

I spied this hanging at an exhibition of international textile artists in the Lake District a couple of weeks back: Roublev-style angels interpreted in quilting and machine embroidery. Unfortunately I managed to cut the artist's name off in my photograph and now can't remember the surname, which was Russian. There was a lot of text used in the design, but it didn't help me decide what the hanging 'meant'  or why icons were the subject of it.
