Crosier (written also Crozier), a staff carried before bishops and other great ecclesiastical dignitaries, the same as the pastoral staff. It is topped by a more or less ornamented crook to indicate the bishop's pastoral authority over his flock. The cross upon the patriarch's crosier has two transverse bars, that upon the pope's crosier has three such bars.
