Born in about 978 in the ducal house of Luxembourg, she married Henry II, later St. Henry, the Holy Roman Emperor (what we might very loosely and anachronistically call the Emperor of Germany, though of much else besides).  Their seat was in the city of Bamberg, which her husband made an important religious centre.  They had no children, though, despite what was said of them by some biographers, they had not apparently taken any particular religious vow in this respect.  In thanksgiving for recovery from a serious illness, she endowed an important monastery at Cassel, and this was nearly finished when her husband died.  Thereafter she devoted herself to a life of prayer, and of care of the sick.  The tales told of her are not without dramatic incident: she once asked to be allowed to walk over a series of hot ploughshares to disprove an accusation of infidelity to her husband.  Her niece Judith, first abbess of the Cassel foundation, proved to be more concerned with feasting and frivolities than with prayer and piety, and after several unsuccessful attempt to reprimand her, aunt Cunegunde slapped her face.  Allegedly the marks remained until the day of her death, a warning to respect the seriousness of religious vows.  They don’t come like that any more!  Cunegund died in 1033 and was buried with her husband in Bamberg Cathedral.  Despite the above-mentioned act of political incorrectness, she was canonised in 1200.
