The Roman general did not simply conquer a city; he first attempted to steal its god. This practice, known as evocatio, was a calculated religious maneuver used during sieges to divert the tutelary deity of a besieged city away from its defenders and toward the Roman army. Rather than looting sacred images, which would be considered impious, Roman commanders would offer the enemy god a more lavish temple and a richer cult in Rome if they surrendered. This ritual dodge allowed the Romans to claim divine favor without committing sacrilege, effectively turning the spiritual defense of a city into a strategic liability for the enemy. The ritual was conducted in a military setting, serving as a threat during a siege or as a result of surrender, and it highlights how deeply intertwined warfare and religion were in the ancient world. Mary Beard, J.A. North, and S.R.F. Price document this in their work Religions of Rome, noting that the goal was to mitigate the looting of sacred objects that would otherwise be sacrilegious. This early form of summoning was not about personal power but about statecraft and the manipulation of divine allegiance on a massive scale.
Theurgy and The Neoplatonic Call
In the philosophical circles of late antiquity, the summoning of spirits evolved from a military tactic into a path of spiritual ascent. Neoplatonism and theurgy introduced a system where the calling forth of spirits was a method to elevate the human soul toward the divine. Practitioners believed that through specific rituals, they could communicate with higher powers and gain knowledge that was otherwise inaccessible to the mortal mind. This tradition moved away from the coercive nature of Roman warfare and embraced a more mystical approach to interacting with supernatural agents. Theurgy, or divine work, became the framework for these practices, where the magician sought to align themselves with the cosmic order rather than dominate it. Manuals from this era laid the groundwork for later magical traditions, establishing a lineage of thought that viewed the summoning of spirits as a means of achieving spiritual perfection. The calling forth of spirits was a relatively common practice in these esoteric systems, creating a bridge between the ancient world and the later developments in Western mystery traditions. This shift marked a critical turning point where the act of summoning became a tool for personal transformation and philosophical inquiry.The Solomonic Grimoires
The 16th century saw the publication of manuals that would define the practice of conjuration for centuries to come. The Greater Key of Solomon the King and the Lesser Key of Solomon, also known as the Lemegeton, became the primary texts for those seeking to command spirits. These grimoires provided detailed instructions on how to construct magical circles, prepare tools, and recite the correct formulas to summon demons and angels. The Sacred Magic of Abramelin the Mage offered a different approach, focusing on the attainment of the knowledge and conversation of the Holy Guardian Angel. These texts were not merely collections of spells but complex systems of ritual magic that required years of preparation and discipline. The manuals described acts of a supernatural or paranormal nature, detailing the precise steps needed to ensure the safety of the magician while commanding the spirits. The influence of these books extended far beyond the pages, shaping the practices of ceremonial magic and influencing generations of occultists. The grimoires served as the classical example of the idea that magic could be systematized and taught, turning the chaotic act of summoning into a structured discipline.John Dee and Edward Kelley
The 16th century also witnessed one of the most famous and controversial partnerships in the history of magic. John Dee, a renowned mathematician and advisor to Queen Elizabeth I, began a series of evocations with Edward Kelley, a self-proclaimed medium. Together, they claimed to have summoned spirits who revealed ancient secrets and prophecies about the future of England. Their work was documented in detailed diaries, which described the rituals and the entities they encountered. The partnership was fraught with tension and scandal, as Kelley's claims of receiving messages from spirits were often met with skepticism by Dee's contemporaries. Despite the controversy, their work had a lasting impact on the development of Western esotericism. The image of John Dee and Edward Kelley evoking a spirit has become an iconic representation of the era's fascination with the supernatural. Their collaboration demonstrated the potential for magic to intersect with politics and religion, as Dee sought to use his knowledge to influence the course of history. The partnership remains a subject of intense study, offering insights into the psychological and spiritual dynamics of the time.Modern Esoteric Revivals
In the 19th and 20th centuries, the practice of conjuration experienced a resurgence within various Neopagan and Hermetic traditions. Groups such as the Hermetic Order of the Golden Dawn and later the Thelema movement adopted and adapted the rituals described in the grimoires. These modern practitioners sought to revive the ancient arts of summoning, blending them with contemporary philosophical and psychological ideas. The act of calling or invoking deities and other spirits became a central part of their spiritual practice, often used for divination and personal growth. Hoodoo and other folk magic traditions also incorporated elements of conjuration, using incantations and charms to cast magical spells. The magic of the grimoires was frequently seen as the classical example of this idea, serving as a foundation for these new movements. The revival of conjuration in the modern era reflects a continued human desire to connect with the supernatural and to find meaning beyond the material world. These traditions have evolved over time, adapting to the changing cultural landscape while maintaining the core principles of the ancient practices.The Psychology of the Summoning
The act of summoning a spirit, whether in ancient Rome or modern times, often involves a profound psychological component. The use of mind-altering substances, whether herbal or chemical, can alter the practitioner's state of consciousness, making them more susceptible to the experience of contact with supernatural agents. This altered state can lead to vivid visions and a sense of connection with the divine or the demonic. The psychological impact of these rituals is significant, as they can provide a framework for understanding the human psyche and its relationship to the unknown. The use of uttered word formulas and the repetition of specific phrases can induce a trance-like state, facilitating the experience of summoning. This psychological dimension of conjuration is often overlooked in favor of the supernatural claims, but it plays a crucial role in the effectiveness of the practice. The interplay between the mind and the spirit, whether real or imagined, remains a central theme in the study of magic and its history.
