Inverted cross

The inverted cross, also known as the upside-down cross, is a symbol that has been used in both Christian and anti-Christian contexts. Historically, it is most commonly associated with Saint Peter, who, according to tradition, was crucified upside down and for whom the symbol represents humility and martyrdom. In modern times, the inverted Latin cross has also been adopted in anti-Christian and Satanic symbolism to signify opposition to Christianity.
