I have been working with Mercury – also known as Mercurius – since 2008 and I still feel like I have only just begun to scratch the surface. Over the years I have encountered Mercury as stately diplomat, knowledgeable teacher, wordsmith, swift-footed divine messenger, lord of commerce, patron of public transportation, god of communication, and also as meddler, confusion-monger, cheat, liar, and thief of wit. His facets are many. In addition to his manysidedness, I will say one of the greatest challenges in my search for Mercury has been his syncretism with Hermes. Sometimes I think I am one of zero people who actually think of Mercury as separate from Hermes. To my thinking, they are like twins; they look alike, but they are different people with their own unique proclivities and personalities.

Roman religion changed drastically following contact with Greek religious beliefs and practices. Prior to contact, the Romans did not have a developed anthropomorphic view of the gods but instead believed in the numina, or spirits. These numina were not human-like but they were the beings in charge of organizing and executing the business of the world. Once the Romans decided to absorb many Greek beliefs and practices, the anthropomorphic gods of Rome were born. Most had Roman numina that served as a sort of ancestor. The Dei Lucrii, spirits of wealth, were the Roman divinities that served as Mercury’s ancestors within early Roman belief. As the religio romana changed and evolved over time, Mercury became associated specifically with commerce and trade, particularly the grain trade. As a result, many merchants and tradesmen were devoted to Him, seeking his blessings and making offerings to him at his temple in the Circus Maximus. By way of Greek religious influence, the caduceus, winged hat, and winged sandals associated with Hermes were attributed to Mercury. This influence was also responsible for expanding Mercury’s (recognized) jurisdiction to include animal husbandry, knowledge, travel, communication, the newly dead (as psychopomp), and divine heraldry, among others.

When I first began to work with Mercury, the vast range and diversity of his influence are what struck me the most. That same quality is what I suspect made it so hard for me to “get” him in the very beginning. As I thought about him more and began meditating with him, it occurred to me that he is first and foremost a God of Exchange. His role in exchange is obvious as a god of trade and commerce, but his reach extends beyond that. To my thinking, exchange is a unifying construct for understanding his specific areas of jurisdiction.  For instance, as a god of animal husbandry, he facilitates an exchange between human beings and the animals and land that produce the stuff that sustains human life. As a god of heralds, he facilitates exchange between nations and other political entities. As a god of omens and divination, he facilitates exchange between humans and the gods. As a guide to the dead, he facilitates the exchange between the world of the living and the world of the dead. As a god of language and knowledge, he facilitates exchange between individual people and between cultures. This is the same exchange that he facilitates as a god of travel, roads, and hospitality. Mercurius was also understood as a god of skill in general. I understand skills as tools that help us to reach some goal or end or to facilitate a process. It makes perfect sense to me that a God of Exchange might need to be skilled at many things.

Related to Mercury’s role as a God of Exchange, he is associated with boundaries – both their maintenance and their crossing. To my understanding, it is in this capacity that he serves as a god of thieves and trickery. Like with most gods, he can bring favor or wrath; he can ward against thieves and grant the intellectual prowess that defends against trickery or he can admit thieves to your property and encourage a dullness of mind that would render one vulnerable to a wily trickster.

Interestingly, during the growth of the Roman Empire, Mercury also became syncretized, via interpretatio romana, with a number of other deities including Odin and Wodan among the Germanic peoples and Lugus and Lugh among the Celts, and many others. I think that Mercury’s tendency to be on the front lines of cross-cultural connections also fits with his role as a God of Exchange. It is noteworthy that no other Roman god seems to have been so quickly and so easily absorbed by so many diverse nations, which the Romans connected with (via trade) or invaded (via military force).

When I think of Mercury, I often associate him with the drive toward connection and exchange that lies at the heart of everyday life. We have interpersonal, political, social, religious, economic, and a host of other exchanges and interactions every single day of our lives. His sphere of influence is clearest to me in the morning when I travel to work. As I stand waiting for public transit, waiting for the business of my day to begin, I often look up into the trees and observe the wind rustling the high leaves and branches. I always think of it as the breath of Mercurius inspiring the connections, interactions, and exchanges of the day to commence.

If you are interested in honoring Mercurius, here’s a ritual that I wrote for him after he helped me through some major milestones in my life. I conducted this ritual with about seven guests present but it can be adapted to solitary work if you wish. What follows is the ritual script as inspired by but not dictated by Roman reconstructionist beliefs and practices. Ritual instructions are in italics and ritual speech is in plain print.

Create altar, start fire in the focus, start coal in the burner, burn purifying herbs – have some purifying herbs still burning when people enter the area.

Process to the ritual area.

Please take a moment to cleanse yourself of any influences that might hinder your ability to engage with the powers.

As we prepare to encounter the sacred, I invite each of you to bring your full awareness and attention to this place and this time in any manner you see fit, setting aside all else. When you are ready, turn your gaze to the altar.

Light the candles, lamp, and stick incense while everyone shifts their awareness to the sacred.

When everyone’s attention has returned to the altar, ring the chime two times.

Over the bowl containing the goat meat, sprinkle mola salsa and wine. Pass knife over the meat while saying…

Now, cut the meat to symbolically kill the goat.

Divide the meat into two or five parts.

Bring the meat to the focus and sprinkle more mola salsa and wine over it.
