Gunther works with extraordinary integrity and intellectual depth. The book is full of illustrative material and citations, which are often footnoted in the original, including the original script. The book thus literally overflows with hieroglyphs, Coptic, Hebrew, Greek, Sanskrit, and even Enochian characters. An intellectual's heart will rejoice. It is certainly a heavy and dense read, and as a non-member of the A∴A∴, I did not fully understand some things and might argue with others. Nevertheless, it was a fascinating read that I definitely did not have to force myself through. The book is supplemented with excellent correspondence tables for the Egyptian alphabet and the trigrams from Liber Trigrammaton.
