The first image of a circle conveys the existence of the sun if I say so, and without a doubt everyone on earth would agree. The circle exudes permanence and its stationary position in our skies and in our solar system.
The second image of the winged disk now conveys a flying sun, passing and not one that is crashing, rather it is suspended in flight.
The winged disk is the re-occurring image in ancient Egypt, also a symbol to represent Isis. The existence of the second sun, that passes through our solar system is represented in antiquity.
