The basis of this book is that Christian women can, like the guardian angels, invisibly govern the world. The author's objective in writing this book was to point out the important role that woman plays in society, and to give the young girl such instructions as will enable her, in due time, to discharge, in a worthy manner, the duties of her calling. Charles de Sainte Foi, Saint Foix and Saint Foy were the pseudonyms used by Éloi Jourdain.
