Have a hard time remembering much about this one. I remember a footnote that a carbuncle could also be a legendary type of animal like an otter with a gem on it's head. I always thought that was a cool little fact.
Undeniably an entertaining read. Costello has managed a seemingly comprehensive gathering of all available reported sightings of the Loch Ness monster up until the time of publication, and thrown in numerous other lake monsters from around the globe for good measure. But one cannot help but be reminded of Sagan's aphorism that "extraordinary claims require extraordinary evidence". The claim that heretofore unrecorded animals exist not just in a single body of water in Scotland, but in fact in potentially hundreds of lakes in almost every country, is extraordinary indeed and I fear that mere eyewitness reports do not constitute sufficient evidence to bear these claims out.
I'll freely admit that the absence of evidence is not evidence of an absence, but a complete lack of hard, physical evidence in the 50 years since Costello's book was first published seems telling.
This is a weird book to read because it's a book on the Loch Ness Monster written fifty years ago. That means that there have been fifty years of development in lake monster hunting. So it's a rather obsolete book to read. So do I rate it base on the validity of Costello's claims through today's light, through 1974's light, or how much enjoyment I got out of it?
I chose the latter. The book was easy enough to read, but I feel that sometimes Costello got bogged down in the wealth of info on lake monsters out there and didn't let you chew on the individual ideas long enough. My favorite sections were the ones on mythology and local oral history, which may also be the most timeless parts of the book. Most of the the ideas presented sound solid to me, but I'm no expert and, honestly, not convinced.
Still, it was an enjoyable enough read and a classic of its arena. If you're interested in Nessie or other lake monsters, give this one a shot.
