the pulpit may be located closer to the main congregation in the nave, either on the nave side of the crossing, or at the side of the nave some way down. This is especially the case in large churches, to ensure the preacher can be heard by all the congregation. Fixed seating for the congregation came relatively late in the history of church architecture, so the preacher being behind some of the congregation was less of an issue than later. Fixed seating facing forward in the nave and modern electric amplification has tended to reduce the use of pulpits in the middle of the nave. Outdoor pulpits, usually attached to the exterior of the church, or at a preaching cross, are also found in several denominations. If attached to the outside wall of a church, these may be entered from a doorway in the wall, or by steps outside. The other speaker's stand, usually on the right (as viewed by the congregation), is known as the lectern. The word lectern comes from the Latin word "lectus" past participle of legere, meaning "to read", because the lectern primarily functions as a reading stand. It is typically used by lay people to read the scripture lessons (except for the Gospel lesson), to lead the congregation in prayer, and to make announcements. Because the epistle lesson is usually read from the lectern, the lectern side of the church is sometimes called the epistle side. In other churches, the lectern, from which the Epistle is read, is located to the congregation's left and the pulpit, from which the sermon is delivered, is located on the right (the Gospel being read from either the centre of the chancel or in front of the altar). Though unusual, movable pulpits with wheels were also found in English churches. They were either wheeled into place for each service where they would be used or, as at the hospital church in Shrewsbury, rotated to different positions in the church quarterly in the year, to allow all parts of the congregation a chance to have the best sound. A portable outside pulpit of wood and canvas was used by John Wesley, and a 19th-century Anglican vicar devised a folding iron pulpit for using outdoors.
