Cross Of St. Peter

Peter is believed to have been crucified upside down at his own request, as he did not feel worthy to die the same way as Jesus. Therefore many Christian sects use this cross as a symbol of humility.

The Cross of St. Peter (Petrine Cross or Peter's Cross) is an inverted Latin cross traditionally used as a Christian symbol, but in recent times also used widely and incorrectly as an anti-Christ symbol, a common but popular misconception. The correct symbolism for the anti-Christ is a inverted crucifix with Jesus Christ hung inverted upon the crucifix.

It is often associated with Satanism and anti-religious attitudes, as it is considered to represent the opposite of Christianity by inverting its primary symbol, the Latin Cross.
