Abstract
This article is about the art of portrait in Fénelon's spiritual correspondence. It distinguishes two categories of portraits: some are generic, others are from the inside, individual and detailed. The article also analyses some exemplary personalities such as the Contesses de Gramont, de Montberon or Madame Guyon. Divergences between "high society portraits" and "spiritual portraits" are outlined. The spiritual portrait is being analysed based on main character studies (Madame de Maintenon and the Duc de Bourgogne), as well as deep speech exploration (lexicon, rhetorical systems). The overall study also takes into account the cultural and scientific context of the time.
