This is a very well researched treatise on the history of the area of New York where the young Joseph Smith lived, on the religions in the area at the time, and on the various accounts that were given by Joseph himself during his life of the "First Vision." It really helped me to understand better his claims of the "religious excitement" in the general area and of the differences in the doctrine that were being preached. This is a very worthwhile study, and has only strengthened my testimony of Joseph Smith.
