A story of infinite coincidences, spanning 940 years of history, from 1060 to 2000. A crossroads where the path taken leads the author to a completely different work in a part of a former Benedictine convent in Florence, the only part of the building mysteriously saved during the siege of 1530. From 4 initials of names, an enigmatic interweaving of esoteric meanings is revealed, in which time with a before and after ceases to exist in favour of parallel temporal dimensions that communicate with each other through codes that, once solved, open the door to other lives, revealing the mysterious origin of the Castel del Monte of Frederick II of Swabia. The narration of the many facts that really happened gives us a vision of reality beyond the Matrix, through a "journey" where spirit and matter interpenetrate, finding a precise place at the centre of the inexplicable mystery that concerns the power of the unconscious in relation to the ego and the self, the subject of long and in-depth studies by the great psychiatrist Carl Gustav Jung, He introduced the new concepts of the collective unconscious, the process of individuation and synchronicity, especially the latter, which Jung studied for over twenty years with the Nobel Prize-winning physicist Wolfgang Pauli, because of its surprising similarities to phenomena found in the field of quantum mechanics.
