The Burning Times is a term referring to the witch persecutions in Europe during the late medieval and renaissance periods. According to Wikipedia, it was first coined by feminist Mary Daly in 1978, who depicted the witch-hunts as a persecution against women. However, the "burning times," without captitalization, does, in fact, appear in Gardner's Witchcraft Today, which predates Daly by about 20 years. Whatever the origin, Wiccans and some other Pagans have certainly adopted the term, and today the phrase generally refers to the theory that Christian witch-hunters were, in fact, attempting to root out practitioners of older pagan religions.

Not only is the myth of the Burning Times false, it's disrespectful to the real victims of the witch-persecutions who were, at first, heretics and then were generally Christians unfortunate enough to be swept up in a hysteria that swept half a continent.
