Aileen wrestles with the problem deep into the early hours.
The formulae and incantations found in the Revelations of the Eyeless King appear to use a ritual system that has its roots deep in history. She finds that there is a signature in the formulae - a certain rhyming scheme, linked with a set of common symbols - that repeats through time: from the Order of Orthodox monks, through to the garbled poetry of Haight-Ashbury.
She can't be certain at this stage, but it could be that the Revelations form a parallel literature - similar to, but not following, the stricter course of this particular tradition.
