From A'albiel to Zuriel, A Dictionary of Angels (including the fallen angels) is a thoroughly comprehensive and well researched text with derivations stemming from sources as diverse as Milton's Paradise Lost to Mather's Greater Key of Solomon. Detailed appendices cover such topics as 'The Angelic Script', 'The Orders of the Celestial Hierarchy', 'The names of Metatron' and 'The Watchers' to name but a few and the thorough bibliography is almost as valuable as the book itself. To the uninitiated, A Dictionary of Angels may at first seem overwhelming, such is it's scale, but Davidson has certainly attained his desire to 'hack... through the the maze of changes in nomenclature and orthography that angels passed through in the course of their being transferred from one language into another...' and on the whole shared appellations are highlighted accurately enough, the exceptions I have found not worthy of mention here. Especially useful are the references to source literature held by each entry. Not all of this is heavy theological stuff, however, and there is enough tongue and cheek humour dotted throughout that one may read this wonderful book cover to cover. Purchase without delay!
