Almost immediately Sibylla suffered a trauma of her own, when her daughter, Jacoba, a baby only a few months old, became so ill that her father wanted her, too, hereticated. Prades Tavernier was still in Arques, staying in the home of another neighbour, Raymond Mauleon, while waiting for the death of Galharda, and he came that night. After hereticating the child, he said that Sibylla ‘should not give the girl food or milk, or anything which is born of flesh, and that, if she lived, she should from then on feed her with Lenten food’. Raymond Peter, her husband, was very pleased, ‘saying that if his daughter died in this state, she would be an angel of God’, but Sibylla could not, as she said ‘see her daughter die in this way’, and she suckled her when her husband was out of the room. The resulting quarrel was so serious that ‘her husband did not love her or her daughter, nor speak to them for a long time until’, as Sibylla put it, ‘he recognised his error’. At the time he was supported by Peter Maury, who called her a bad mother and said that women were demons.
