I can't resist: if the VMs were found in a grave
in Wales, where it had rested for several
centuries, it can hardly have been written by
an Italian noble lady of the late 1400s.... ;-)
Claiming that everything revealed to Edward Kelly was true would be a
somewhat stronger position that I would be happy to take. :-)
Oh, and thanks for the link: I've been there a good number of times
already. :-) Note that it's missing from the linked bibliography page, but
the British Library has a copy of Carl Cristophe Schmieder's 1832
"Geschichte der Alchemie" (shelfmark 1395.h.17).
Morhof's "Epistola ad Langelottum" is quoted in Volume 1 of J. J. Mangeti's
"Bibliotheca Chemica curiosa, seu rerum ad Alchemiam pertinentium Thesaurus
..... quo non tantum artis auriferae ... historia traditur ... verum etiam
tractatus omnes virorum celebriorum, qui ... de chrysop?a scripserunt ...
exhibentur. " Which, again, the British Library has at least one copy of
(though it may have three, or one copy may have three separate shelfmarks).
It also has a copy of "Histoire de la philosophie hermetique" (by LENGLET
DU FRESNOY. Pierre Nicolas).
But as for where to find the "Edelgeborne Jungfrau Alchimia", I'm afraid
you've got me beaten. :-/
