In architecture and sculpture, a pluteus (plural plutei) is a balustrade made up of massive rectangular slabs of wood, stone or metal, which divides part of a building in half; in a church they fulfil the same function as an iconostasis or rood screen, separating the nave from the chancel.[1][2] They are decorated with frames in relief or richly decorated with figures or geometric motifs.
One set of examples is the so-called Plutei of Trajan, discovered between the Comitium and the Column of Phocas in the Roman Forum in 1872 and another is the Plutei of Theodota.
