In the Early Church, the sanctuary was connected directly to the nave. The choir was simply the east part of the nave, and was fenced off by a screen or low railing, called "cancelli", which is where the English word chancel comes from. The development of the architectural feature known as the choir is the result of the liturgical development brought about by the end of persecutions under Constantine the Great and the rise of monasticism. The word "choir" is first used by members of the Latin Church. Isidore of Seville and Honorius of Autun write that the term is derived from the "corona", the circle of clergy or singers who surrounded the altar.
