In 'Deadly Sins' (Series 3, Episode 4), Dafydd discusses the mysterious practice of Sin-Eating.
First recorded in the 17th century by the Oxford antiquarian and biographer, John Aubrey, Sin-Eating survived in the Welsh Marches into the 20th century, when a wealthy farmer, named Richard Munslow, revived the practice.
A Sin-Eater would consume food regarded as contaminated by another person's sin, and, in doing so, take on the sins of that person.
Through reconstructions of the Sin-Eating ceremony, and by visiting the home and grave of Munslow, Dafydd, presenter Sal Masekela, and Morgan Freeman, reflect on the beliefs that underpinned the practice of Sin-Eating, and ask why anyone would choose to consume another person's sin.
