Perhaps more interestingly, ‘virgin’ is a word used by a number of writers seeking to explore feminine spirituality. This is an example:

Miranda Gray divides the menstrual cycle into four phases which she terms virgin, mother, enchantress and hag. (Virgin, in this context, refers to the period between bleeding and ovulation.) Part of her intent, perhaps, is to rehabilitate the word ‘hag’ which usually has strongly negative connotations. Much the same may apply to ‘crone’ in the feminist Daughters of the Moon tarot, which uses (with similar meaning) the words maiden, mother and crone for its court cards.
