The Description of a New World, Called the Blazing-World

One time, when the Duchess her Soul was with the Empress, she seem'd to be very sad and melancholy; at which the Empress was very much troubled, and asked her the reason of her Melancholick humour? Truly, said the Duchess to the Empress, (for between dear friends there's no concealment, they being like several parts of one united body) my Melancholy proceeds from an extream Ambition. The Empress asked, What the height of her ambition was? The Duchess answered, That neither she her self, nor no Creature in the World was able to know either the height, depth, or breadth of her Ambition; but said she, my present desire is, that I would be a great Princess. The Empress replied, so you are; for you are a Princess of the fourth or fifth Degree, for a Duke or Duchess is the highest title or honour that a subject can arrive to, as being the next to a King's Title; and as for the name of a Prince of Princess, it belongs to all that are adopted to the Crown; so that those that can add a Crown to their Arms, are Princes, and therefore a Duke is a Title above a Prince; for example, the Duke of Savoy, the Duke of Florence, the Duke of Lorrain, as also Kings Brothers, are not called by the name of Princes, but Dukes, this being the higher Title.
