Set of two glass windows with an inner frame of four ruyi-shaped pieces (right side)

The right window extends the foundation of these two four-piece ruyi patterns by dividing the lower four closed-mouthed petals into unequal halves and moving one half to the top. There are four open-mouthed ruyi-shaped petals in the middle section. This unusual and charming window structure, made up of a variety of similar elements, is one of a kind.
