Many of the Book of Enoch books available are in fact public domain (the R. H. Charles version of 1917) which means that they can be given away to anyone for free, by anyone. This book is NOT one of those. What is the problem with public domain versions? They are full of errors, as they are around 100 years old and out-dated scholarship. Sure, they might be cheap, but most of the information is wrong. World renowned scholar Dr. A. Nyland has a doctorate in ancient languages and word meaning. She was a college professor at the University of New England, Australia, lecturing in ancient languages. She has appeared on television and radio numerous times speaking about ancient languages and ancient peoples. These days, many non-translators (some of whom actually claim to be translators) sell the public domain version of 1917 by R.H. Charles (both as is, and also disguised by slight rewording) as a commercial venture. This version reflects the knowledge of The Book of Enoch as it was back in 1917. Great advances have been made since then. This (all 3 Books of Enoch) is a NEW (2010) and easy-to-read translation by ancient languages scholar Dr. A. Nyland and is NOT the 1917 R.H. Charles Public Domain translation of The Book of Enoch. The Book of Enoch is of importance to theosophy and mysticism. This book is an easy to read translation with cross references, copious background notes, and notes. This new translation by Dr. A. Nyland contains all 3 Books of Enoch: 1) 1 Book of Enoch (Also called The Ethiopic Book of Enoch) 2) 2 Book of Enoch (Also called The Slavonic Book of Enoch, The Secrets of Enoch). Also contains the extended version of 2 The Book of Enoch, The Exaltation of Melchizedek. 3) 3 Book of Enoch (Also called The Hebrew Book of Enoch) The Books of Enoch are of interest to a wide audience: theosophy, mysticism. 1 Book of Enoch tells of the Watchers, a class of angel, who taught humans weapons, spell potions, root cuttings, astrology, astronomy, and alchemy. The Watchers also had sex with human women and produced the Nephilim. For this, they were imprisoned and cast into Tartarus. This is also mentioned in the New Testament. In 2 Book of Enoch, two angels take Enoch through the 7 heavens. This volume contains the extended version of 2 Book of Enoch, The Exaltation of Melchizedek. In 3 Book of Enoch, Enoch ascends to heaven and is transformed into the angel Metatron. This is about the Merkabah and is of interest to those who study mysticism and magic, and to Kabbalists. People interested in theosophy or mysticism will find this book invaluable, as will Rosicrucians.
