In reading through parts of the book on Gabriel, I had a very hard time connecting in any way to Gabriel through what Mr. Webster wrote for the following reasons;
1. He has Gabriel as being associated with the Element of Water when he is the Archangel of Air.
His feast day is on March 24th which is just after the Sabbat of Spring Equinox or for others Ostara [Spanish for Egg] and we all know this is the season that is connected to the element of Air. Then we have Gabriel who is depicted with a scroll which we know too is associated to Air as it is use to write and communicate our messages.
2. The stones listed in the book are all connected to Water, when in truth Gabriels favourite stone is known by many to be that of Citrine, which is a stone that is connected to Gemini and that too is the most mutable sign of the Air and the first of the Air Signs.

I would think that in his book Raphael the review would be the same only in reverse to this one and that the books should be retitled according to the proper elemental connections as well as the Feast days and seasons in which they lye.

In another note I would find this book more helpful in working with the Archangel of Raphael and just changing the names of the angels around to fit properly in the reading.

Blessed Be!
