Pope Joan & The Prophecy of The Tiara

Imagine a tale so scandalous, so revolutionary, that the most powerful institution on Earth would go to extraordinary lengths to erase it from history. A story of a woman, disguised as a man, ascending to the very pinnacle of the Catholic Church: the Papacy. This is the enduring, fiercely debated legend of Pope Joan, a medieval figure whose existence is inextricably linked to a chilling prophecy concerning the Papal Tiara and a hidden Vatican ritual. If you’re drawn to historical controversies, to secrets whispered in hushed tones, and to the profound impact of suppressed truths, then prepare to question everything you thought you knew about the Vatican’s past.
The Legend of Pope Joan
The legend of Pope Joan is one of the most persistent and fascinating enigmas of the Middle Ages. It tells of a brilliant and pious woman who, driven by a thirst for knowledge denied to women of her era, disguised herself as a man. Excelling in her studies, she rose through the ecclesiastical ranks, eventually reaching Rome. Her intellect, eloquence, and apparent virtue impressed cardinals and commoners alike, leading to her unthinkable election as Pope, supposedly in the 9th century (though the exact dates vary in different versions of the tale).
Under the name of John Anglicus or John VIII, she is said to have reigned for over two years, a period of apparent competence and wisdom. However, the story reaches its dramatic and tragic climax when, during a papal procession through the streets of Rome, she suddenly gave birth. Her true identity was thus revealed, leading to her immediate death (either from shock, complications, or by an enraged mob) and the swift, brutal suppression of her memory by the Church. Was she a real historical figure, or a powerful allegory? The debate continues to rage.
The Prophecy of the Tiara
Central to the legend of Pope Joan, and arguably contributing to its longevity, is the Papal Tiara. This magnificent, tri-crowned headpiece was for centuries the symbol of papal authority, representing the Pope’s triple power as Father of Princes and Kings, Ruler of the World, and Vicar of Christ on Earth. Its very design, weight, and history are steeped in immense symbolism.
The connection to Pope Joan lies in a purported prophecy or belief that if a woman were ever to occupy the Papal throne, the Tiara would either fall from her head (symbolising the illegitimacy of her rule), or that its inner workings would somehow reveal her true gender. This prophetic aspect heightened the dramatic tension of the Joan legend, making the very symbol of papal power intertwined with the fear of female usurpation.
While no actual prophecy related to a female pope and the tiara is officially documented by the Church, its persistent mention in conjunction with Joan underscores the deep anxieties surrounding the possibility.
The Sedes Stercoraria: The Hidden Papal Ritual
Perhaps the most infamous and unsettling element of the Pope Joan legend is its purported consequence: the Sedes Stercoraria (Latin for ”dung seat” or ”excrement chair”) and the ritual associated with it. According to the legend, after the scandal of Pope Joan, the Church supposedly instituted a ritual for future papal elections to prevent a similar deception.
Upon his election, the new Pope would be seated on a special, perforated marble chair (the Sedes Stercoraria). A junior cardinal would then supposedly reach underneath to physically verify the new pontiff’s masculinity, uttering the phrase ”Testiculos habet et bene pendunt” (”He has testicles and they hang well”), to which the assembly would reply, ”Deo gratias” (”Thanks be to God”).
This bizarre and undignified ritual, if true, would have been a profoundly humiliating measure designed to confirm male gender. While the historical existence of such chairs (two of which are in the Vatican Museums) is confirmed, their purpose is debated.
The Church maintains they were ancient Roman commode chairs reused, or symbolic chairs related to humility, rather than instruments for gender verification. Nevertheless, the persistent legend of this ritual further cements Pope Joan’s story as a historical scandal of monumental proportions.
The Vatican's Alleged Cover-Up
The core of the Pope Joan legend is built upon the premise of a massive Vatican cover-up. Proponents argue that the Church, deeply embarrassed and threatened by such an unprecedented event, systematically removed all records of her pontificate, altered official histories, and suppressed any mention of her existence. This alleged erasure is why Joan’s name does not appear in official papal lists.
Sceptics, however, point to the lack of contemporary evidence in legitimate papal chronicles or extensive historical records. They argue that such a monumental deception, especially involving a public birth during a procession, would have been impossible to entirely suppress in an era of widespread communication (even if by rumour).
Many historians believe the legend originated as anti-papal satire, a Protestant polemic, or a popular allegory reflecting medieval anxieties about female authority and clerical celibacy. Despite the lack of definitive proof, the very act of debate and the lingering question mark over Joan’s existence make her one of the most captivating and controversial figures in Vatican lore.
Uncovering the Legend
While the Vatican won’t explicitly endorse the legend of Pope Joan, a visit to this historical and spiritual epicentre allows you to stand in the very places where these powerful stories unfold, fostering a deeper connection to the mysteries.
How to get there: Vatican City is easily accessible from Rome via public transport (Metro Line A to Ottaviano-S. Pietro station, or numerous bus lines) or taxi.
What to expect on arrival:
- Vatican Museums: Here you can see two Sedes Stercoraria chairs. While the official explanation for their use differs from the Pope Joan legend, seeing them in person, with the legend in mind, is a powerful experience. You’ll pass through countless rooms where papal history unfolded.
- St. Peter’s Basilica: Imagine papal processions moving through these grand spaces. The sheer scale and history of the Basilica provide a backdrop for a story of such immense scope.
- Vatican Library & Archives: These are not publicly accessible for casual visitors, but they are the very repositories where evidence for or against Joan’s existence would theoretically be found. The knowledge of their immense, sometimes secret, collections only adds to the mystique.
Best time to visit: Vatican City is incredibly popular, so expect crowds. Visiting in the shoulder seasons (spring or autumn) or very early in the morning/late in the afternoon can help avoid the worst of the crowds for the museums.
If the allure of hidden histories, suppressed truths, and the explosive possibilities of a female pontiff captivates you, then a journey to the Vatican offers a profound opportunity to walk through the very halls that guard one of Europe’s most intriguing and hotly debated historical mysteries.
