Iconostasis is Fr. Pavel's final theological work. Composed in 1922, it explores in highly original terms the significance of the icon: its philosophic depth, its spiritual history, its empirical technique. In doing so, Fr. Pavel also sketches a new history of both Western religious art and the Orthodox icon: a history under the direct operation of the Holy Spirit. The work is original, challenging and profoundly articulate. This translation is the first complete English version.
