“It is perhaps oddly appropriate that the symbol for the god Mercury was the caduceus—two snakes entwined on a winged rod. The symbol is commonly and incorrectly associated with the medical establishment, due to a mistake when the US Army Medical Corps adopted the symbol in 1902. Soon after, it became a ubiquitous sign of healing. But in fact, the caduceus represents Mercury—the god of financial gain, commerce, thieves, and trickery.”
