Donald J. Sobol is not a scholar of the ancient world so anything you've heard about his ground-breaking work may be incorrect. It is a good introduction to the scholarship and theories about Amazons through the 1970s. It is a good attempt to make the layperson aware of the different stories and tales about Amazons in the ancient world. However, unlike I've seen claimed in political motivated studies of Amazons, this book is not a collection of the legends themselves. In fact, Sobol rarely gives citations and flat out states that he combining various accounts into one for each legend type he examines. Read this for the backgound of previous scholarship; go get a Loeb for the actually texts or wait until my dissertation is published because it will have all the texts.
