Crosier
A crosier or crozier (also known as a paterissa, pastoral staff, or bishop's staff) is a stylized staff that is a symbol of the governing office of a bishop or abbot and is carried by high-ranking prelates of Roman Catholic, Eastern Catholic, Eastern Orthodox, Oriental Orthodox,Malankara Mar Thoma Syrian Church,and some Anglican, Lutheran, United Methodist and Pentecostal churches.
In Western Christianity the usual form has been a shepherd's crook, curved at the top to enable animals to be hooked. In Eastern Christianity, it is found in two common forms: tau-shaped, with curved arms, surmounted by a small cross; or a pair of sculptured serpents or dragons curled back to face each other, with a small cross between them.
Other typical insignia of prelates are the mitre, the pectoral cross, and the episcopal ring.
