The Caduceus is a Symbol of Light, composed of Two Monads.
Each Monad is characterized by a spherical Vortex of Energy, i.e. Potentiality of Movement.
The Two Monads are represented as Saturn, to highlight that a spherical Vortex has a certain Spin and allows stable orbits on its equatorial plane.
Then each Monad makes the other revolve on its own equatorial plane, giving rise to an overall Interaction that propagates in a straight line.
