The rood screen (also choir screen, chancel screen, or jube) is a common feature in late medieval church architecture. It is typically an ornate partition between the chancel and nave, of more or less open tracery constructed of wood, stone, or wrought iron. The rood screen would originally have been surmounted by a rood loft carrying the Great Rood, a sculptural representation of the Crucifixion. In English, Scottish, and Welsh cathedrals, monastic, and collegiate churches, there were commonly two transverse screens, with a rood screen or rood beam located one bay west of the pulpitum screen, but this double arrangement nowhere survives complete, and accordingly the preserved pulpitum in such churches is sometimes referred to as a rood screen. At Wells Cathedral the medieval arrangement was restored in the 20th century, with the medieval strainer arch supporting a rood, placed in front of the pulpitum and organ.

At Wells Cathedral the medieval arrangement was restored in the 20th century, with the medieval strainer arch supporting a rood, placed in front of the pulpitum and organ. Rood screens can be found in churches in many parts of Europe, however, in Catholic countries they were generally removed during the Counter-reformation, when the retention of any visual barrier between the laity and the high altar was widely seen as inconsistent with the decrees of the Council of Trent. Accordingly, rood screens now survive in much greater numbers in Anglican and Lutheran churches; with the greatest number of survivals complete with screen and rood figures in Scandinavia. The iconostasis in Eastern Christian churches is a visually similar barrier, but is now generally considered to have a different origin, deriving from the ancient altar screen or templon. The word rood is derived from the Saxon word rood or rode, meaning 'cross'. The rood screen is so called because it was surmounted by the Rood itself, a large figure of the crucified Christ. Commonly, to either side of the Rood, there stood supporting statues of saints, normally Mary and St John, in an arrangement comparable to the Deesis always found in the centre of an Orthodox iconostasis (which uses John the Baptist instead of the Apostle, and a Pantokrator instead of a Crucifixion). Latterly in England and Wales the Rood tended to rise above a narrow loft (called the 'rood loft'), which could occasionally be substantial enough to be used as a singing gallery (and might even contain an altar); but whose main purpose was to hold candles to light the rood itself. The panels and uprights of the screen did not support the loft, which instead rested on a substantial transverse beam called the 'rood beam' or 'candle beam'. Access was via a narrow rood stair set into the piers supporting the chancel arch. In parish churches, the space between the rood beam and the chancel arch was commonly filled by a boarded or lath and plaster tympanum, set immediately behind the rood figures and painted with a representation of the Last Judgement. The roof panels of the first bay of the nave were commonly richly decorated to form a celure or canopy of honour; or otherwise there might be a separate celure canopy attached to the front of the chancel arch. The carving or construction of the rood screen often included latticework, which makes it possible to see through the screen partially from the nave into the chancel. The term 'chancel' itself derives from the Latin word cancelli meaning 'lattice'; a term which had long been applied to the low metalwork or stone screens that delineate the choir enclosure in early medieval Italian cathedrals and major churches. The passage through the rood screen was fitted with doors, which were kept locked except during services. The terms; pulpitum, Lettner, jubé and doksaal all suggest a screen platform used for readings from scripture, and there is plentiful documentary evidence for this practice in major churches in Europe in the 16th century. From this it was concluded by Victorian liturgists that the specification ad pulpitum for the location for Gospel lections in the rubrics of the Use of Sarum referred both to the cathedral pulpitum screen and the parish rood loft. However, rood stairs in English parish churches are rarely, if ever, found to have been built wide enough to accommodate the Gospel procession required in the Sarum Use. The specific functions of the late medieval parish rood loft, over and above supporting the rood and its lights, remain an issue of conjecture and debate. In this respect it may be significant that, although there are terms for a rood screen in the vernacular languages of Europe, there is no counterpart specific term in liturgical Latin. Nor does the 13th century liturgical commentator Durandus refer directly to rood screens or rood lofts. This is consistent with the ritual uses of rood lofts being substantially a late medieval development. Until the 6th century the altar of Christian churches would have been in full view of the congregation, separated only by a low altar rail around it. Large churches had a ciborium, or canopy on four columns, over the altar, from which hung altar curtains which were closed at certain points in the liturgy. Then however, following the example of the church of Hagia Sophia in Constantinople, churches began to surround their altars with a colonnade or templon which supported a decorated architrave beam along which a curtain could be drawn to veil the altar at specific points in the consecration of the Eucharist; and this altar screen, with widely spaced columns, subsequently became standard in the major churches of Rome. In Rome the ritual choir tended to be located west of the altar screen, and this choir area was also surrounded by cancelli, or low chancel screens. These arrangements still survive in the Roman basilicas of San Clemente and Santa Maria in Cosmedin, as well as St Mark's Basilica in Venice. In the Eastern Church, the templon and its associated curtains and decorations evolved into the modern iconostasis. In the Western Church, the cancelli screens of the ritual choir developed into the choir stalls and pulpitum screen of major cathedral and monastic churches; but the colonnaded altar screen was superseded from the 10th century onwards, when the practice developed of raising a canopy or baldacchino, carrying veiling curtains, over the altar itself. Many churches in Ireland and Scotland in the early Middle Ages were very small which may have served the same function as a rood screen. Contemporary sources suggest that the faithful may have remained outside the church for most of the mass; the priest would go outside for the first part of the mass including the reading of the gospel, and return inside the church, out of sight of the faithful, to consecrate the Eucharist. Churches built in England in the 7th and 8th centuries consciously copied Roman practices; remains indicating early cancelli screens have been found in the monastic churches of Jarrow and Monkwearmouth, while the churches of the monasteries of Brixworth, Reculver and St Pancras Canterbury have been found to have had arcaded colonnades corresponding to the Roman altar screen, and it may be presumed that these too were equipped with curtains. Equivalent arcaded colonnades also survive in 10th-century monastic churches in Spain, such as San Miguel de Escalada. Some 19th-century liturgists supposed that these early altar screens might have represented the origins of the medieval rood screens; but this view is rejected by most current scholars, who emphasize that these screens were intended to separate the altar from the ritual choir, whereas the medieval rood screen separated the ritual choir from the lay congregation.
