What did the Amazons symbolize in The Book of the City of Ladies?

The mythical all female warrior civilization, known as the Amazons, is utilized by Pizan as a model for the all female city that expects setting forth and creating. As Pizan states in the beginning of the book, the Amazons were able to convene together and lead their society successfully without any male presence and Pizan admires how they were able to build and maintain a society through their own rule and determination. Pizan also mentions how they were so commited that they were even willing to mutilate themselves to reach their goals. Amazon warriors burned off their left breast so they could carry a shield more effectively and their right breast removed so that they could shoot arrows more effectively. The removal of a single breast is a symbolic act of immense commitment. They were willing to sacrifice a piece of their own body in the defense of their way of life. The Amazons are symbolic of their dedication to a goal and their willingness to make very personal sacrifices even if it means being able to achieve an objective in the long run.
