"Sylph" is a two-volume book published in the 18th century by the English writer and political activist Georgiana Spencer Cavendish, Duchess of Devonshire. In these books, the author depicts the world of British society of her time, introduces the reader to the depths of intrigues and political games that the aristocratic sorority lived by. However, the main emphasis is on the internal struggle of the main character, who remains disconnected between the worlds of spirits and people. "Sylph", offering the reader a satirical look at the life of the upper class of English society, is at the same time a deep philosophical work, reflecting on the nature of freedom, love and self-awareness.
