One of them was the Dauphin who became King Louis XIII. Her habit of language and her vocabulary demonstrate that she was belonging to both of popular and educated worlds. Obstetrics was not free of Hippocrates and Galen conceptions and the theoretic weakness of her written works is noticeable while Paré then Guillemeau began the increasing knowledge of obstetrics.
