Agnes is a Persona in Persona 5 Royal.
"The mysterious female pope of the Middle Ages. She posed as a man and eventually made it all the way up to pope due to her unrivaled intellect. Her existence shook the history of the Catholic church."
Agnes is based on Pope Joan, a legendary Medieval woman who reigned as pope for a short period, going against the Catholic Church's ingrained tradition of male popes. Though the story was widely believed for centuries, modern historians have found no evidence of her existence and believe the legend to be a work of fiction meant to discredit the church.
Most versions of her story describe her as a talented and learned woman who disguised herself as a man, often at the behest of a lover. In the most common accounts, due to her abilities, she rose through the church hierarchy and was eventually elected pope. Her sex was revealed when she gave birth during a procession, and she died shortly after, either through murder or natural causes. The accounts state that later church processions avoided this spot, and that the Vatican removed the female pope from its official lists and crafted a ritual to ensure that future popes were male.
She might also be based on Agnes of Rome , a virgin martyr, venerated as a saint in the Roman Catholic Church, Eastern Orthodox Church, the Anglican Communion, and Lutheranism. According to tradition, Agnes was a member of the Roman nobility, born in AD 291 and raised in an early Christian family. She suffered martyrdom at the age of twelve or thirteen during the reign of the Roman Emperor Diocletian, on 21 January 304. A beautiful young girl, Agnes had many suitors of high rank, and the young men, slighted by her resolute devotion to religious purity, submitted her name to the authorities as a follower of Christianity.
She was condemned to be dragged naked through the streets to a brothel. In one account, as she prayed, her hair grew and covered her body. It was also said that all of the men that attempted to rape her were immediately struck blind. She was led out and bound to a stake, but the bundle of wood would not burn, or the flames parted away from her, whereupon the officer in charge of the troops drew his sword and beheaded her, or, in some other texts, stabbed her in the throat. It is also said that her blood poured to the stadium floor where other Christians soaked it up with cloths.
