The title "dean" (Latin
decanus) may derive from the custom of dividing a
hundred into ten
tithings, not least as rural deaneries originally corresponded with wapentakes,
hundreds,
commotes or
cantrefi in Wales. Many rural deaneries retain these ancient names. The first mention of rural deans comes from a law made by
Edward the Confessor, which refers to the rural dean being appointed by the
bishop "to have the inspection of clergy and people from within the district to which he was incumbent... to which end [he] had power to convene rural chapters." The first known rural dean is Robert de Eclesfield, who was appointed to the position in the diocese of York in 1148. In medieval times rural deans acted as officers of the diocesan bishop and prepared business for the
archdeacons to determine at their visitations. Archdeacons gradually took over most of the duties of rural deans and the office was allowed to become a sinecure by the 16th century. ==Roman Catholic usage==
