>The Cross of Saint Peter also known as Petrine Cross is an inverted Latin cross traditionally used as a Christian symbol. In Christianity, it is associated with the martyrdom of Peter the Apostle. The symbol originates from the Catholic tradition that when sentenced to death, Peter requested that his cross be upside down, as he felt unworthy of being crucified in the same manner as Jesus. The Petrine Cross is also associated with the papacy, reflecting the Catholic belief that the pope is the successor of Peter as bishop of Rome.
