Greg Jenner is joined in 17th-Century Italy by Professor Michelle Sauer and comedian Sophie Duker to learn about notorious nun Benedetta Carlini. From the moment of her birth in 1590, Benedetta – whose name literally means ‘blessed’ – was dedicated to God’s service by her father. As a young girl, she joined a community of religious women, where in her twenties she began experiencing mystical visions. These culminated in a number of miraculous signs and occurrences, including the appearance of the stigmata on her body. But following a papal investigation, shocking secrets were revealed, including her sexual relationship with another nun. This episode charts her life, from the miracles that occurred during her childhood, through her time as a devout nun, and to her ultimate downfall at the hands of the papal investigator.
