Caduceus - Rod of Hermes Picture

Now used in the medial profession, the Caduceus rod was a staff carried by Hermes as a symbol of peace. It served as a badge of protection for ancient Greek and Roman heralds and ambassadors.

Also symbolic of Mercury, the Caduceus is a figure of two serpents wrapped around a center rod. The rod is a symbol of transforming alchemical power. The two serpents represent polarity or duality. Together with the sprouted wings depict the caduceus having an alchemical meaning of balance, duality and following the alchemical process leading to unity.
