Ever imagined the fate of a medieval girl who dared to defy tradition? Someone who refused to marry and bear children? For Batilda Bigbum from Littledick, the consequence is a fiery death at the stake. Christbride, Bebe Cave’s one-woman character show, throws us straight into the flames, opening with her agonised screams before she recounts the absurd and irreverent tale of how she ended up in such a predicament. And what follows is one of the most exhilarating, laugh-friendly hours you’ll spend this Fringe.

Cave is a masterful storyteller, weaving audience interaction, humour and hasty costume changes into a performance that is equal parts theatrical brilliance and comedic gold. With nothing more than a few outfit tweaks and an array of accents, she transforms into characters including Batilda’s disapproving mother, a parade of disastrous suitors and a chorus of nuns, all while maintaining an infectious energy that keeps her audience hooked.

The year is 1384 and Batilda is prepping for a banquet with potential husbands; but this isn’t your typical Middle-Ages courtship. Instead the audience is treated to Batilda serving a medieval GRWM (‘get ready with me’ for the TikTok-illiterate) complete with a fit check and a bardcore rendition of Charli xcx’s ‘360’. Shame her hennin (cone-shaped headdress) couldn’t hide her small forehead. When it comes to choosing a potential mate, things don’t go as planned and she does what any self-respecting weird medieval girl would do: abandons marriage altogether and becomes a bride of Christ instead.

The audience is then taken on a religious journey as Batilda leaves a life of monotony for an existence of devotion. But devotion, like delusion, has its limits. As Batilda’s self-belief ramps up, the line between sainthood and deception blurs and the result involves fake miracles, divine fraud, dark confessions and, of course, a healthy dose of witch accusations.

In an age where credulity runs rampant, Christbride delivers a riotous, historical farce about the dangers of unwavering confidence, proving delusion burns just as bright as heresy. Cave’s show is a masterclass of anarchic comedy, blending historical detail and shameless modern humour. Her performance is chaotic, clever and brimming with genuine love for the absurdity of the past. This will make you laugh until your sides hurt and secretly glad you weren’t born in the Middle Ages. Unmissable.
