Monique Wittig, Les Guérilléres (Avon) 1976 - pg 61:

"They do not say that vulvas with their elliptical shape are to be compared to suns, planets, innumerable galaxies. They do not say that the vulva is the primal form which as such describes the world in all its extent, in all its movement. They do not in their discourses create conventional figures derived from such symbols."
