The Æsch Mezareph or Ash Metzareph, is only known to persons of Western Culture from the Latin Translation found in a fragmentary condition in the work entitled Kabalah Denudata by Knorr von Rosenroth, published at Sulzbach in 1677-84. These volumes have as a sub-title "The Transcendental, Meta-physical and Theological Doctrines of the Hebrews", and they enshrine a Latin translation, with part of the Hebrew text and commentaries, of the great Sohar or ZOHAR, "The Book of Splendour" which is the most famous of all the Hebrew mystical codices of the Kabalah. Three of the principal tracts of the Zohar are now familiar to English readers through the translation of my friend. MacGregor Mathers his edition of The Book of Concealed Mystery, The Greater Holy. Assembly, and The Lesser Holy Assembly, has obtained so great a circulation that I am emboldened to issue this volume, which exemplifies the Kabalistic scheme of Alchymy, as one of the series of Collectanea Hermetica. The Æsch Metzareph is still extant as a separate treatise in what is called the Hebrew language, but which is more properly Aramaic Chaldee: it was a companion volume to the Chaldean Book of Numbers so often referred to by H. P. Blavatsky, and which is no longer to be procured, although I have reason to think that copies still exist in concealment. "Sapere Aude"
