Some historians have speculated that the rose in Gothic architecture is a secret symbol of the feminine principle, one of a multitude of hermetic symbols found in these churches.  The symbol itself dates back to Roman times, where it was called the ‘Rose of Venus.’ The rose, with its characteristic five petalled shape
mimicked the pentagrammatic path traced by the planet Venus in the night sky. This, combined with the flower’s natural beauty, made it an obvious symbol of the Goddess of love.”
    The five-petal flower, the rose, the five-pointed star, the moon and Venus can all represent the female principle when we study occult symbolism. The huge rose window of Notre-Dame de Chartres in Paris represents the Virgin Mary (Notre-Dame means “Our Lady”). The symbol of the planet Venus (♀) is also used to represent the female sex .
