Used this book for research on Incan Mythology. It is a really useful guide, as long as you have some background info so you know what the book is talking about.

The set includes not only the more familiar myths such as Greek and Roman, but pretty well succeeds in its goal to include all of humanity. The text is extremely detailed but very readable; none of the turgid prose so often associated with academia. The volumes contain numerous illustrations, both in the text and as plates (mostly black & white.)

One of the most useful parts of the set is the last volume, an extremely detailed index, which allows the reader to pursue a theme, or even a topic as specific as the significance of belts, across all the volumes. The individual volumes do not have their own indices, but the tables of contents are fairly detailed.
