Image above title from Wiki : Modern depiction of the caduceus as the symbol of logistics.
Y’all can go around the houses, up and down, left and right, back and front with YOUR Logic.
But – for me – the Caduceus is a symbol that is PERFECTLY encoded.
The straight staff in the middle depicts LOGIC/Religion/3D stuff.
The spiralling snakes either side depict SPIRIT/Divine/Higher Knowledge.
Hermes/Mercury IS the Winged MESSENGER, yes?
And I do NOT deny STRAIGHT Logic. It is needed every bit as much as SPIRALLING knowledge.
Sigh.
Mercury/Hermes
The Greek god Hermes (the Roman Mercury ) was the god of translators and interpreters. He was the most clever of the Olympian gods, and served as messenger for all the other gods. He ruled over wealth, good fortune, commerce, fertility, and thievery.
