In Eastern Christianity, an iconostasis is a wall of icons and religious paintings separating the nave from the sanctuary in a church. “Iconostasis” can also mean a portable icon stand that can be placed anywhere within a church. There are strict rubrics governing the placement of icons within the iconostasis, and far from being a mere decorative scheme, it is designed to give the worshiper a meticulously orchestrated glimpse of heaven, a mystical window looking in on the holy of holies.
