Artist Lachlan Goudie presents a highly personal documentary, inspired by his father, in which he investigates why witches have cast such a powerful spell over generations of artists.From early woodcuts of shrieking hags to Victorian depictions of the seductive sorceress, our familiar stereotypes of the witch have been conjured up from artists' imaginations and in The Art of Witchcraft, Lachlan marvels at the enduring power of their imagery, reveals the role that some artists played in fuelling the hysteria of the witch trials and argues that the witch in art offers a vivid commentary on changing attitudes to sex, superstition and the supernatural.
