On Thursday December 19th, 2013 The Hermetic Hour, with host Poke Runyon, will have as its distinguished guest the noted author on subjects arcane and esoteric, John Michael Greer. John's first book "Paths of Wisdom" has been of considerable help to us as an authoritative source in our on-going series of lectures on the Hermetic-Qabalistic Tree of Life. John is also the translator of the medieval Latin version of "Picatrix", with Christopher Warnock, which has now become as important in the magical revival as Tyson's Agrippa. Although certainly a Hermetic scholar John Michael Greer's magical heart lies in the Celtic-Druidic tradition. He has written several books in this area and is a practicing Druid himself. His latest work combines the Hermetic Golden Dawn and the Druidic traditions, both of which were active in Victorian England. John discovered a historic interchange between these two very British expressions and he has lovingly reconstructed the synthesis in "The Celtic Golden Dawn," -- So, let us go out to Stone Henge and see how the Druids do a Pentagram Ritual.
