context_page_description: In Eastern Christianity, an iconostasis is a wall of icons and religious paintings, separating the nave from the sanctuary in a church. Iconostasis also refers to a portable icon stand that can be placed anywhere within a church. The iconostasis evolved from the Byzantine templon, a process complete by the 15th century.
  A direct comparison for the function of the main iconostasis can be made to the layout of the great Temple in Jerusalem. That Temple was designed with three parts. The holiest and inner-most portion was that where the Ark of the Covenant was kept. This portion, the Holy of Holies, was separated from the second larger part of the building's interior by a curtain, the "veil of the temple". Only the High Priest was allowed to enter the Holy of Holies. The third part was the entrance court. This architectural tradition for the two main parts can be seen carried forward in Christian churches and is still most demonstratively present in Eastern Orthodox churches where the iconostasis divides the altar, the Holy of Holies where the Eucharist is performed – the manifestation of the New Covenant – from the larger portion of the church accessible to the faithful.
context_section_description: Archaeological evidence from the St. John of Stoudios monastery in Constantinople suggests that the Iconostasis evolved from the early templon. A basilica dedicated to John the Baptist was built in 463 AD. In it the chancel barrier surrounded the altar in a π shape, with one large door facing the nave and two smaller doors on the other sides. Twelve piers held chancel slabs of about 1.6 meters in length. The height of the slabs is not known. The chancel barrier was not merely a low parapet (a short wall); remains of colonnettes have been found, suggesting that the barrier carried an architrave on top of the columns.
  In early churches, including the Hagia Sophia ("Great Church") in Constantinople, the altar, at least in large churches, was under a ciborium ("ciborion": κιβώριον in Greek), usually a structure with four columns and a domed canopy. This had curtains on rods on all four sides, which were closed for sections of the liturgy, as is still performed in the Coptic and Armenian churches. a comparison with the biblical Veil of the Temple was intended. The small domed structures, usually with red curtains, that are often shown near the writing saint in early Evangelist portraits, especially in the East, represent a ciborium, as do the structures surrounding many manuscript portraits of medieval rulers. As the iconostasis grew, the ciborium declined, although some late examples, by now invisible to the congregation, were produced.
  The templon gradually replaced all other forms of chancel barriers in Byzantine churches in the 6th, 7th, and 8th centuries, except in Cappadocia. The invention of the solid icon screen is ascribed to Saint Basil the Great.
  As late as the 10th century, a simple wooden chancel barrier separated the apse from the nave in the rock-cut churches in Derinkuyu, though by the late 11th century, the templon had become standard. This may have been because of the veneration and imitation of the Great Church Hagia Sophia in Constantinople, though the columnar form of chancel barrier does predate Hagia Sophia.
  The rood screens or pulpita that most large European Roman Catholic churches and cathedrals had acquired by late medieval times occupied a similar position between chancel and nave but served a different function. The choir was usually east of the screen. Many survive, often most completely in Scandinavia, and more were built in the Gothic Revival, particularly in Anglican churches in England. In wooden examples, painted panels were typically waist-high, with a wooden tracery section above allowing a view through, and then a large carved beam supporting a rood cross crucifix, often life-size, above that. Larger churches had stone screens, which might impede virtually all view by the congregation.
