What The Prieuré de Sion Actually Is
The Prieuré de Sion was a modern invention, established in the early 1960s by Pierre Plantard. It claimed to be an ancient secret society dating back to 1099, but archival research confirmed the documents were fabricated. The "rituals" that exist today come from later initiatory systems built around the legend, primarily the Orontean Grade system developed within French occult circles during the 1970s and 1980s. This isn't to dismiss the value of working with these rituals entirely. People treat them as a framework for personal spiritual work, meditation practice, and exploration of Western esoteric themes. The question is whether you understand what you're engaging with before you start.
The Core Ritual System
The most commonly circulated structure is the four-grade system associated with the Orontean degree. Each grade has a specific ritual, symbolic framework, and set of meditative exercises. The grades, in order of progression, are: This is the entry-level ritual. It involves a consecration space, symbolic tools, and a meditation on the figure of Merovech, the legendary founder Plantard identified as the first Grand Master of the Prieuré. The ritual typically lasts 45 minutes to an hour and centers on establishing a personal connection to the lineage narrative. You'll need a prepared altar area, candles, water, salt, and incense. The basic structure follows a purification sequence, an invocation segment, and a closing seal. This second degree introduces the Celtic and Gallic threads of the legend. The ritual incorporates a longer meditative sequence and a working with directional energies. It's where the work shifts from introductory to more demanding. The main challenge people hit here is maintaining focus through the extended visualization. I found that breaking the meditation into three distinct phases with short physical resets between them made a real difference. Without that structure, my attention wandered and the whole sequence felt hollow.
The third degree ties together the political and spiritual strands of the tradition. The ritual is more complex, involving a detailed symbolic map of what the Prieuré claims as its historical territory and influence. This is where the work becomes less about personal meditation and more about engaging with the broader narrative framework. The ritual requires more preparation time—roughly two hours including setup and cleanup. People often underestimate this because the written description makes it sound shorter than it actually is in practice. The final degree in this system is rarely described in detail publicly. What exists in print tends to be fragmentary. The published versions vary significantly between sources, and some appear to be embellishments rather than faithful reproductions of any original text. The primary sources circulate through a few channels. The most referenced collection is held within the archives of the Ordo Templi Orientis, which maintains some documentation of the Orontean system. There are also scanned copies available through various esoteric discussion forums and digital archive sites like the Esoteric Archive and the Sacred Texts website. The key is verifying the source, because the documents have been copied, recopied, and occasionally altered across decades of underground circulation.
Get the Full Details

A trustworthy version will include attribution to its origin, a clear notation of which grade it covers, and ideally references to the manuscript tradition it draws from. If a document appears without any provenance, treat it with skepticism. I once worked from a copy that had been lightly edited to insert references to a different esoteric order, which confused the ritual structure considerably until I spotted the inconsistency. Cross-referencing at least two independent sources before following any ritual text is standard practice and worth the effort. The Orontean rituals are not dramatic spectacles. They are structured meditative works with symbolic actions layered on top. The effect depends heavily on your baseline discipline and how seriously you take the symbolic framework. Some people find the repetitive elements grounding. Others find them tedious and move on quickly. The real work happens in the meditation segments. The symbolic actions are scaffolding. If you skip the internal work because you're focused on getting the external details right, the ritual tends to feel empty. I learned this the hard way during my second attempt at the Cymric Grade. I spent so much time worrying about candle placement and incense timing that I had no mental space left for the actual visualization. The workaround was simple: I practiced the physical sequence separately until it became automatic, then concentrated exclusively on the meditative component during the actual working.
Common Pitfalls
The biggest mistake people make is treating the Prieuré de Sion rituals as if they carry some unique, hidden power simply because of the organization's association with conspiracy theory. They don't. The rituals draw on standard Western esoteric techniques: consecration, invocation, meditation, sealing. The framework is specific, but the underlying methods are well established in broader occult practice. Another issue is the tendency to romanticize the Merovingian legend without doing the historical reading. If you're going to work with these rituals seriously, read at least some of the primary scholarship on Plantard and the forgery debate. Understanding the actual history doesn't invalidate the spiritual work, but it does prevent you from building your practice on a foundation of misinformation.
The Priory Of Sion Rituals And Modern Adaptation
Several contemporary practitioners have adapted the Orontean system for solo work. The original texts were written with group ceremony in mind, but the core meditative structure translates reasonably well to individual practice. The main adjustment is replacing the communal invocation with a self-directed one, which requires more internal discipline but is entirely workable. If you're new to this type of work, I'd suggest starting with the introductory materials on Western ceremonial magic before attempting the Merovingian grade. The jump from beginner to advanced in this system is not small, and rushing it usually leads to frustration rather than insight.

For further reading, the works of Norman Cohn on the forgery of the Protocols and the broader Dossier affair provide essential historical context. On the practical side, the Ordo Templi Orientis publications contain the most complete versions of the Orontean ritual texts currently available. Various discussion groups on esoteric forums also maintain curated collections of sourced documents, though verification remains your responsibility.
