Crosier
Crosier (kr?"zh?r) , noun
[Old English rocer, croser, croyser, from croce crosier, Old French croce, croche, French crosse, from Late Latin crocea, crocia, from the same German or Celtic sourse as French croc hook; akin to English crook.]
The pastoral staff of a bishop (also of an archbishop, being the symbol of his office as a shepherd of the flock of God.
The true shape of the crosier was with a hooked or curved top; the archbishop's staff alone bore a cross instead of a crook, and was of exceptional, not of regular form.
