Also, the scroll seems to be the well-known treasure
map(s) so is the book of St. Dunstan still a scroll?
All I know is: on Rafal's site, Edward Kelley is quoted as having made
forty pages of extracts from it, whereas the treasure scroll is actually
only two pages (I read through it as part of the Liber Mysteriorum
yesterday - thanks to Mark Parry for telling me what I was looking at).
Also, the mysterious writing is known to be on the
scrolls, rather than the Book of St.Dunstan.
I don't know whether the book was encrypted as well - some accounts say it
was, but who knows?
