Masks of the Illuminati, by Robert Anton Wilson (Books 2008, 21)
If you had asked me a few months ago whether I had read this I'd have said yes. I thought that I had read most, if not all, of Wilson's books that are in linked to the Illuminatus trilogy. But I'd have been wrong.
This one features James Joyce and Albert Einstein drinking in a bar in Zurich in 19??. They meet one Sir John Babcock, who has been studying magick (though from a Christian perspective) under the guidance of the Society of the Rose Cross, or Rosicrucians.
Maybe. Unless it’s something else.
Stuff happens. Magic and monsters ensue, or people are made to believe that they do.
It’s not the best or most momentous of his works, but he makes the characters of Einstein and Joyce surprisingly compelling, and Babcock is an affecting innocent abroad, and it all keeps you reading. Good stuff.
