Given the question: Information: - The nave is the central aisle of a basilica church, or the main body of a church (whether aisled or not) between its western wall and its chancel. It is the zone of a church accessible by the laity. - An icon (from Greek "eikn" "image") is a religious work of art, most commonly a painting, from Eastern Christianity and certain Eastern Catholic churches. The most common subjects include Christ, Mary, saints and/or angels. Though especially associated with "portrait" style images concentrating on one or two main figures, the term also covers most religious images in a variety of artistic media produced by Eastern Christianity, including narrative scenes. - A sanctuary, in its original meaning, is a sacred place, such as a shrine. By the use of such places as a haven, by extension the term has come to be used for any place of safety. This secondary use can be categorized into human sanctuary, a safe place for humans, such as a political sanctuary; and non-human sanctuary, such as an animal or plant sanctuary. - The royal doors , holy doors , or beautiful gates are the central doors of the iconostasis in an Eastern Orthodox or Greek - Catholic Church . In Orthodox Churches , the sanctuary is separated from the nave by a wooden screen called the iconostasis . The iconostasis represents Christian continuity from the veil of the Temple in Jerusalem which separated the people from the Holy of Holies that housed the Ark of the Covenant . Normally , the iconostasis has three doors in it . The two single doors to the right and left are called '' deacons ' doors '' or '' angel doors '' and they usually have on them icons of either sainted deacons ( Saint Stephen , Saint Lawrence , etc. ) or the Archangels Michael and Gabriel . These are the doors that the clergy will normally use when entering the altar . The central double doors are the '' holy doors '' ( Slavonic : Svyatya Vrata ) , which are considered to be most sacred , and may only be entered at certain sacred moments during the services , and only by ordained clergy ( deacons , priests , bishops ) . The term Royal Doors ( Slavonic : Tsarskiya Vrata ) is commonly used to describe the Holy Doors , because Christ passes through these gates during the Great Entrance at the Divine Liturgy ( and most especially during the Liturgy of the Presanctified Gifts ) . More properly , however , these doors should be called the '' Beautiful Gate '' , and in Greek this is the only term used , although the official English sites of the Ecumenical Patriarchate , the Orthodox Church in America and the Antiochian Orthodox Church all use the term '' Royal Doors '' . In Russia , they are sometimes called the '' Red Gates '' , red being synonymous with beautiful . Whatever its name , a typical gate consists of two hinged doors . Often they will be only half - height , but sometimes they go almost all the way to the top of the opening . The doors themselves are made of wood or metal and usually have painted on them an icon of the Annunciation in the form of a diptych ( the Theotokos on the... - In Eastern Christianity an iconostasis (plural: iconostases) 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 fifteenth century. - A templon (from Greek meaning "temple", plural "templa") is a feature of Byzantine churches consisting of a barrier separating the nave from the sacraments at the altar. The solid templon first appeared in Christian churches around the 5th century and is still found in many Eastern Christian churches. Initially it was a low barrier probably not much different from the altar rails of many Western churches. It eventually evolved into the modern iconostasis, still found in Orthodox churches today. It is usually composed of carved wood or marble colonnettes supporting an architrave (a beam resting on top of columns). Three doors, a large central one and two smaller flanking ones, lead into the sanctuary. The templon did not originally obscure the view of the altar, but as time passed, icons were hung from the beams, curtains were placed in between the colonnettes, and the templon became more opaque. In modern Orthodox churches, it is common for the openings of the templa to be constructed specifically to contain icons. - Eastern Christianity consists of four main church families: the Eastern Orthodox Church, the Oriental Orthodox Churches, and the Assyrian Church of the East, as well as the Eastern Catholic Churches (that are in communion with Rome but still maintain an Eastern liturgy). The term is used in contrast with Western Christianity (namely the Latin Church and Protestanism). Eastern Christianity consists of the Christian traditions and churches that developed in the Middle East, Africa, Eastern Europe, Asia Minor, the Balkans, Southern India and parts of the Far East over several centuries. The term does not describe a single communion or religious denomination. Some Eastern churches have more in common historically and theologically with Western Christianity than with one another. The various Eastern churches do not normally refer to themselves as "Eastern", with the exception of the Assyrian Church of the East and its offshoots. What is the relationship between 'royal doors' and 'work of art'?
The answer is:
