J.Z.P. will find a fully satisfactory answer to his Query, in regard to
the real difference between the crozier and the pastoral staff, on
referring to the article headed "Crozier," in the _Glossary of
Architecture_. It is there stated, that "the crozier of an archbishop is
surmounted by a cross; but it was only at a comparatively late time,
about the 12th century, that the archbishop laid aside the pastoral
staff, to assume the cross as an appropriate portion of his personal
insignia." From which it may be inferred, that the only existent real
difference between the crozier and the pastoral staff is, that the
former is surmounted by a cross, and the latter is as it was before the
12th century, viz., surmounted by "a head curled round something in the
manner of a shepherd's crook;" and the difference in regard to their
use, that the crozier pertains to the archbishops, and the pastoral
staff to the bishops.
