bOING bOING, a popular blog founded by Robert Anton Wilson fan Mark Frauenfelder, posts about an article from a new book, DARKLORE VOL. II, "an anthology of writings on high weirdness and secret history," explains bOING bOING blogger David Pescovitz. The article is about a 1797 book by David Robison, "Proofs of a Conspiracy Against All the Religions and Governments of Europe," that attributed the French Revolution to to the Illuminati.
Pescovitz doesn't mention ILLUMINATUS!, but the commenters are quick to make the connection. One of them helpfully included a link to a scanned copy of Robison's book.
