The word
chancellor derives, believe it or not, from the Italian word for wooden latticework,
cancelli. In the church architecture of sixth-century Rome, a latticework screen demarcated an area near the altar where deacons or priests would stand, waiting to assist the principal celebrant as needed. In English, this area became known as the
chancel. In consequence, a trusted assistant came to be known as a
chancellor. In the High Middle Ages, that title was given to the cleric who would correspond on behalf of and maintain the archives for an important churchman, such as a bishop.
