Margaret Murray points out (God of the Witches, 1931) that it would have taken more than a dropped garter to embarrass a woman in the 14th Century. This garter was probably a ritual one, signifying that its owner was a leader among the non-Christian (Pagan) population. In other words, the Countess of Salisbury was a High Priestess of witchcraft! To drop the garter before the high dignitaries of the Church who were present could certainly have caused some real embarrassment. Edward's action was smart thinking; in placing the garter on his own leg, he not only saved face for the Countess but proclaimed himself willing to be a leader of the Pagan population of England as well as the Christian.
