This Book, as is Peter Berresford Ellis's Dictionaty of Celtic Mythology, is in my opinon deserve 6+ stars, not 5. "Irish Mythology" is not really covered in his "Celtic mythology book, Celtic Mythology is really a continuation of of this book, covering a much broader scope. I have over a dozen "Dictionaries and Encyclopedias of Celtic Mythology, Legend and Lore" and the scope and breadth of the information covered by Mr. Ellis is excellent. As you look up each entry, a full explanation is given, and if your curosity is peaked, it is easy to look up all other referances that are mentined in the text. Stories of Irish mythology, that I didn't fully grasp before, are very clear and understandable.
