agia Adamica_, in
1651 the _Lumen de Lumine_; in 1652 the _Aula Lucis_ (p. 211). In 1654
Valentin Andreae died, and Vaughan succeeded him as _Summus Magister_ of
the Rosie Cross, the event being announced to him by the homage of three
demons, Leviathan, Cerberus, and Belphegor (p. 214). In 1655 he
published his _Euphrates_, and in 1656 made his head-quarters at
Amsterdam or Eirenaeopolis. In 1659 came his _Fraternity of R. C._; in
1664 his _Medulla Alchymiae_.[30] In 1666 he exhibited the philosopher's
stone to Helvetius at La Haye and converted him to occultism: in 1667 he
at last resolved to publish his Opus Magnum, the _Introitus Apertus_,
already written in 1645 (p. 215). In 1668 this was followed by the
_Experimenta de Praeparatione Mercurii Sophici_ and the _Tractatus Tres_
(p. 236). The time was now approaching when Vaughan, in fulfilment of
the pact of 1644, must disappear from earth. He named Charles Blount as
his successor (p. 237), and was granted a magical vision of his
grandson, the child of Diana Wulisso-Waghan and a Lenni-Lennap (p. 239).
He finished his _Memoirs_, published the _Ripley Revised_[31] and the
_Enarratio Methodica trium Gebri Medicinarum_, left his poems to his
brother Henry, who published them in the next year as the _Thalia
Rediviva_,[32] and on March 25, 1678, disappeared in the company of
_Lucifer Dieu-Bon_ himself (p. 240). This event is vouched for, not only
by a written statement of Henry Vaughan (p. 114), but also by the
existence in a masonic triangle at Valetta of a magical talisman into
which, when properly evoked, the spirit of Philalethes enters and
records his glorious end for the edification of the Luciferians
present[33] (p. 243).

I fear that I have taken Miss Vaughan with undue seriousness. Her
account of Thomas Vaughan is not only unsupported by direct
evidence,[34] but much of it is of a character which we should not be
justified in accepting, even were direct evidence forthcoming. And it is
all discordant with the little that we do happen to know of Thomas
Vaughan from other sources. The whole thing is, in fact, a pretty
obvious romance of very modern fabrication. It appears to have been
compiled from such information as to the alchemical and mystical writers
of the seventeenth century as was within the reach of Albert Pike and
the brothers Vaughan about the year 1870.[35] It is always better to
explain than to refute an error; and the nature of the Luciferian
tradition
