In September 1332, in the town of Świdnica, an important economic and communication centre of what was then Silesia, a group of sixteen women stood before the Dominican inquisitor, John of Schwenkenfeld, to testify about the local community of beguines, who called themselves the Hooded Sisters or the Daughters of Odelindis. We are fortunate that the original records of this heresy interrogation have survived, preserved as a notarial instrument drawn up shortly afterwards, eventually transferred to the Papal Curia, and now kept in the Vatican Library. The documents provide unique insights into the everyday life and spirituality of this group of lay women, as they attempted to adopt the ideals of vita apostolica. They lived in the strict poverty they thought necessary for spiritual perfection, and took part in austere ascetic practices, including regular flagellation and a strict diet regime, aiming to mortify sinful flesh and help them achieve mystical union with God.

Using this evidence, the authors of this book piece together a sense of who these interrogated beguines were and the nature of their spiritual practices. Were they pious illiterates, or self-trained theologians, keenly interested in debates around the doctrine of such intellectuals as Master Eckhart, John Duns Scotus and Thomas Aquinas? The book also addresses the nature of their interrogation and the conduct of Friar John of Schwenkenfeld. And it contains a full edition and, for the first time, a full English translation of the documents themselves.
