Walk into any metal concert or browse through a horror movie poster collection, and you’ll see it. The inverted cross. Most people look at it and immediately think of something dark, maybe even sinister or "anti-Christian." It’s become a visual shorthand for rebellion. But honestly? That’s mostly a Hollywood invention.
The Cross of St Peter—or the Petrine Cross—has a history that is way more fascinating and deeply rooted in early church tradition than most TikTok "experts" would have you believe. It’s not a symbol of hate. Historically, it’s actually the ultimate symbol of being humble.
What Really Happened with the Cross of St Peter?
To understand why a cross would ever be turned upside down, we have to go back to Nero's Rome around 64 AD. Christianity was a fringe movement, and the Great Fire of Rome had just devastated the city. Emperor Nero needed a scapegoat. He picked the Christians.
Peter, one of the original apostles and a leader of the early church, was caught up in these persecutions. According to the Acts of Peter, an apocryphal text from the late 2nd century, Peter was sentenced to crucifixion. This wasn't unusual for the time, as the Romans were unfortunately quite efficient at this specific form of execution.
But Peter made a request.
He didn't think he was worthy. He looked at the way Jesus had died and felt that, as a mere man and a flawed follower who had famously denied Christ three times, he didn't deserve to die in the exact same manner. He asked to be crucified upside down. The Romans, likely indifferent to the theology but happy to oblige a more painful variant, complied.
This act of extreme self-deprecation is what gave us the Cross of St Peter. For centuries, if you saw an upside-down cross in a cathedral or on a papal throne, you weren't looking at something "edgy." You were looking at a tribute to a man who didn't want to be compared to his teacher.
The Papal Connection and the Vatican
If you visit the Vatican today, you might see the Petrine Cross in places that would shock someone who only knows it from The Conjuring.

The Pope is considered the successor of St. Peter. Because of this, the inverted cross is a recurring motif in Catholic iconography. During Pope John Paul II's visit to Israel in 2000, he sat in a chair that had a large inverted cross carved into the back. It caused a bit of a stir online years later among conspiracy theorists, but to the Church, it was just standard symbolism. It was a nod to the chair's occupant being the "Successor of Peter."
It’s kinda funny how the meaning shifted so drastically in the public eye.
When Did It Become "Evil"?
The shift happened relatively recently in the grand scheme of history. Throughout the Middle Ages and the Renaissance, the Cross of St Peter remained a symbol of the papacy and humility.
The pivot started around the 19th century. French occultist Éliphas Lévi began writing about inverted symbols as representations of the reversal of the natural order. However, the real "Satanic" branding didn't stick until the 1960s. Anton LaVey, who founded the Church of Satan, didn't actually use the inverted cross as his primary symbol—he preferred the Sigil of Baphomet. But pop culture stepped in and filled the gaps.
Think about movies like Rosemary’s Baby (1968) or The Exorcist (1973). Filmmakers needed a visual way to signal "the opposite of God." Flipping a cross was an easy, high-impact visual. It’s basically branding. Eventually, the music scene caught on. Death metal and black metal bands in the 80s and 90s adopted it to shock parents and establish an anti-establishment identity.
It worked. Now, the original meaning is almost totally buried under decades of horror tropes.
Nuance Matters: It’s All About Context
Context is everything. You’ve probably seen the "Petrine Cross" and the "Satanic Cross" and thought they were the same thing. Technically, they are the same shape. But the intent is what defines them.

- In a Catholic Church: It represents the martyrdom of Peter and the humility of the Papacy.
- In a Black Metal Music Video: It represents a rejection of traditional religious values.
- In Art History: It’s a specific identifier for St. Peter, much like St. Catherine is associated with the wheel or St. Lawrence with the gridiron.
It’s worth noting that many modern Christians find the use of the inverted cross in secular media offensive, not because they don't know the history of Peter, but because they recognize that the user intends it as an insult. It’s a linguistic shift. Words and symbols change meaning based on who is speaking.
Common Misconceptions You Should Stop Believing
There’s a lot of misinformation floating around, especially in "true crime" or "paranormal" circles.
First off, the inverted cross isn't "the sign of the Antichrist." There is no mention of an upside-down cross in the Book of Revelation or any other biblical prophecy regarding the Antichrist. That’s pure Hollywood.
Secondly, using the Cross of St Peter doesn't automatically make someone an occultist. If you see it on an old gravestone or in a 15th-century painting, it’s almost certainly a religious tribute.
Lastly, the "Cross of Nero" is sometimes used as a synonym, but that's historically messy. While Peter died under Nero, the symbol itself is tied to Peter’s choice, not the Emperor’s design.
Why the History of the Symbol Still Matters Today
Symbols are the language of the human experience. When we lose the history of a symbol like the Cross of St Peter, we lose a bit of cultural literacy. We start seeing "evil" where there is actually a story of sacrifice and profound modesty.
It’s a reminder that human perception is fickle. What one generation views as an act of ultimate devotion, another generation views as a sign of rebellion. It also highlights the power of the media to overwrite thousands of years of tradition in just a few decades.

Understanding the Petrine Cross allows for a more nuanced view of history and art. When you look at Caravaggio's Crucifixion of Saint Peter, you see the struggle, the tension, and the awkwardness of being hung upside down. You see a man who is literally and figuratively turning the world on its head because he felt he wasn't good enough to stand upright.
Actionable Takeaways for the Curious
If you’re interested in exploring this further or just want to be the smartest person in the room next time someone brings up "satanic" symbols, here is what you can do:
Verify the Source
Next time you see an inverted cross in an old building or piece of art, look for other clues. Is there a set of keys nearby? Keys are the traditional symbol of St. Peter (the "Keys to the Kingdom"). If you see keys and an inverted cross, it’s 100% a religious reference to the Apostle.
Check the Era
If the object predates the 1960s, the chances of it being meant as a "satanic" symbol are incredibly low. Symbols from the 1800s and earlier almost always follow the traditional Petrine meaning.
Look at Artistic Intent
In modern fashion, the inverted cross is often just an aesthetic choice. Many designers use it simply because it’s a geometric shape that looks "cool" or "edgy." Don't assume a deep ideological stance based on a t-shirt from a fast-fashion retailer.
Read the Primary Sources
If you want the full story of Peter's martyrdom, look up the Acts of Peter. While not part of the official Bible, it’s the primary source for the crucifixion story and provides a lot of "flavor" to the early Christian era. It’s a wild read and gives you a much better sense of the gritty, chaotic atmosphere of Rome in the first century.
Respect the Duality
Understand that a symbol can have two completely different meanings at the same time. You can respect the historical Petrine Cross while acknowledging that, in a modern cultural context, it has taken on a new life. Both things can be true.
The Cross of St Peter serves as a perfect example of how history isn't static. It’s a living, breathing thing that gets reinterpreted by every generation that touches it. Whether you see it as a mark of a martyr or a badge of a rebel, its power to provoke a reaction hasn't faded in two thousand years.
