The word refers to the presence and prominence of the bishop's or archbishop's chair or throne, raised above both clergy and laity, and originally located facing the congregation from behind the High Altar. In the ancient world the chair, on a raised dais, was the distinctive mark of a teacher or Rhetor and thus symbolises the bishop's role as teacher.
