Reid Psaltis' small book about so-called mythical creatures is really a delight. True to the title, the discussion of each creature briefly covers both sides of the argument for, or against, the existence of a cryptid. But what got me hooked is that, in the Preface, Psaltis states:
The purpose is not to defend nor deny the existence of any of its subjects. I feel their existence is moot. [Cryptozoology] is less a study of monsters than it is of human understanding.
True, indeed. But as the discussion is brief, the real reason to buy this book is for the wonderful artwork you'll find throughout. A sampling of which you can view at the author's website. The book is well worth the measly $6 cover price. I got my copy at Quimby's.
