How much philosophical, literary and artistic creativity correlates with the Royal Art (Hierophany of the Ancients), the process of spiritual transmutation of the Hermetic philosophers, and how this is connected with the consciousness and subconscious in the perception of literary and mystical, musical and visual works - all this will be discussed in the collection of essays by Vladimir Tkachenko-Hildebrandt “A Book as Large as Life,” published in the series edited by him “Mystical Cults of the Middle Ages and the Renaissance.” The internal logic of the book is subordinated to the question of dedication and dedicatory action, promoting the consideration of the personalities of government dignitaries, philosophers, servants of literature and art from a new perspective, which sometimes leads to very paradoxical conclusions about their intellectual and creative activity.
