"A crosier (also known as a crozier, paterissa, pastoral staff, or bishop´s staff) is a stylized staff that is a symbol of the governing office of a bishop or Apostle and is carried by high-ranking prelates of Roman Catholic, Eastern Catholic, Eastern Orthodox, Oriental Orthodox, Anglican, and some 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." - (en.wikipedia.org 10.09.2020)
