Arcana Naturae publishes original research contributions, as well as documented essays on specific points. The journal also publishes editions and critical commented translations, critical reviews, and book reviews ; the official working languages are French, English and Italian. Arcana Naturae is directed by Donato Verardi (University of London) assisted by Thibault Rioult (École Nationale Supérieure of Paris), with the support of the Association Francophone pour l'Étude Universitaire des Courants Ésotériques (FRÉSO).
