Hermetic architecture is the architecture built under Hermes, god of de-territorialisation and thresholds, the labyrinth and passages, discoveries and interactions: the most important god of Greek spatiality and certain fundamental and timeless architectural strategies | This is a polyhedral book that believes in the knowledge of the space around us, as the practice of experimentation with form. It is shaped like a many-sided crystal showing forms and worlds, all inside buildings and places.
