The term "ludibrium" was used frequently by Johann Valentin Andreae (1587 - 1654) in phrases like "the ludibrium of the fictitious Rosicrucian Fraternity" when describing the Rosicrucian Order, most notably in his Chymical Wedding of Christian Rosenkreutz, published anonymously in 1616, of which Andreae subsequently claimed to be the author and which has been taken seriously, as virtually a third of the Rosicrucian Manifestos. However, in his Peregrini in Patria errores (1618) Andreae compares the world to an amphitheatre where no one is seen in their true light. This conception of the Rosicrucian world as theater was popularized by the French Situationist Guy Debord in Society of the Spectacle (1967).
Paul Arnold translated Andreae's usage as farce, but this conception has been contested by Frances Yates (Yate 1999), who suggests that Andreae's use of the term implies more nearly some sort of "Divine Comedy", a dramatic allegory played in the political domain during the tumult which preceded the Thirty Years' War in Germany.
Similarly, the melancolic Jacques in As You Like It (1599-1600) asserts that "All the world's a stage, And all the men and women merely players."
It has been suggested that Situationist International was a ludibrium devised by Asger Jorn. Like the Rosicrucians, the Situationist International was a very small group which nevertheless became notorious, even if only for a while. This conception can function as a technique whereby mental projections can be cast into the social imagination.
The Priory Of Sion fascinates me, because it has all the appearances of being a real conspiracy, and yet if you look at the elements another way, it looks like a very complicated practical joke by a bunch of intellectual French aristocrats. And half of the time I believe it really is a practical joke by a bunch of intellectual French aristocrats. And then part of the time I think it is a real conspiracy.
