 However, the Archbishop of Canterbury is also entitled to be preceded by the ancient primatial cross of Canterbury (still in ceremonial use) which is of an ornate historical design, made of precious metal, and with precious stones inserted, but unlike his metropolitical cross (or those of other archbishops) it is not double-barred.Archbishops exist in all traditional denominations of the Eastern Christianity, including Eastern Orthodox Church, Oriental Orthodox Churches, Eastern Catholic Churches and others.In the Eastern Orthodox Churches, the office and title of archbishop can be traced from the 4th and 5th century.
