I have to say this is the best version of Abramelin I have seen; it seems that Mather's used a French text, rather then the German text. This text was originally written in German and translated from the German version, so this book contains more accuracy then Mather's version as a whole. I have to say I found it to be odd that Mather's had 350 squares, of which none were complete and contained a mixture of numbers and letters; but in this book all the squares are filled with the names of the unclean spirits. There is the first book which entails the Journey of Rabbi Moshes journey and the letters to his son Lamech, that reads almost identical to Mather's version. The Second Book contains the Kabbalistic formula that from Jewish traditions, butter, honey, and other very basic ingredients. The third book contains how the book works as a whole with the formula, especially with the unclean spirits. The 4th book contains all the squares that are filled with the names of the unclean spirits. This is one of my favorite grimoires and it is worth the purchase. ( )
