A ''bishop'' is a high-ranking member of the Christian Catholic clergy. He traditionally wears a [[miter]] and oversees a [[diocese]]. The word is based on the Latin word ''episcopus,'' literally meaning ''overseer.'' In some churches, a bishop is regarded as part of the [[apostolic succession]]. In [[chess]], a bishop is a piece that moves diagonally. The traditional shape of the piece includes a stylized representation of the mitre, the two-piece folding cap traditionally worn by bishops, cardinals, and popes.{{Fact}}
