Kerukeion

The kerukeion, also spelled kerykeion or caduceus, is a staff entwined by two serpents and often surmounted by a pair of wings. It is a symbol with a rich history, primarily associated with the Greek god Hermes and the Roman god Mercury. These deities were known as messengers and heralds, and the kerukeion represented their authority and their role as intermediaries between the gods and mortals.

Historically, the kerukeion's origins are somewhat debated. One common interpretation suggests the serpents symbolize duality, such as opposing forces, or the balance between good and evil. The wings are generally understood to represent swiftness and the ability to travel quickly, befitting a messenger god.

The kerukeion was not solely a symbol of divine authority. It also held significance in trade and negotiation, as Hermes was also the god of commerce. This association led to the kerukeion being adopted as a symbol for various commercial and professional organizations, particularly in North America. However, its use in this context is often confused with the Rod of Asclepius, a different symbol of healing featuring a single serpent. The kerukeion is distinct from the Rod of Asclepius and its symbolic meanings differ accordingly.
