Some accounts assert that the oldest imagery of the caduceus is rooted in Mesopotamia with the Sumerian god Ningishzida; his symbol, a staff with two snakes intertwined around it, dates back to 4000 BC to 3000 BC.[3] This iconography may have been a representation of two snakes copulating.[4]
The Winged Sun symbol is Zoroastrian (500 BCE)
