Overall, Forgotten Worlds is an interesting read with a few major flaws that keep it out of the realm of "Excellent." Beginning with the good, there is some examination of lesser known aspects of forgotten history, such as the caucasoid mummies of China and Mongolia. As a reader of this genre, I was surprised to find I hadn't heard of this phenomenon yet. So, there is some new information in this book. As a fan of alternative history I am sometimes reluctant to make new purchases because I fear I will have heard everything presented in similar books. This is the case with Forgotten Worlds, to some extent.
Moving onto the bad. I have a few main complaints that might make it seem I didn't enjoy the book, which is not true. The book sort of lumbers along, for perhaps too many pages (or screens on my Kindle?) trying to connect ancient myths to Atlantis. There is no new evidence of Atlantis presented, just summarizations of theories most of us have already heard. The author explores Norse mythology and, for several pages, simply recounts many Norse tales and the lineages of their gods.
Additionally, the author borrows so heavily from sources that it becomes difficult at times to separate source material from his own writing. He quotes extensively, so much so that I did lose track if I was reading his words or another author's. He also provides citations for paragraph after paragraph, sometimes five or six in a row, which leaves the impression that he is not bringing many new ideas to the table. Fans of this genre will likely find they are already familiar with the works he sources.
Mr. Chouinard does present some unique theories, and I must confess I was not fully on board. The middle of the book is dedicated to offering evidence of a global "Western European" influence. I am not exaggerating when I say he gives credit to Western Europeans for almost every advanced ancient civilization in the Northern Hemisphere. He presents the idea that Norse-type peoples had contact with the ancient central American tribes, Aztecs and the like. The reasoning behind this is because the god Quetzalcoatl is presented as having a beard and pale skin. This seems to me a huge leap. Indian (Hindu) gods are presented with blue skin, but does that mean they had to have had contact with blue-skinned people? If we are to believe every god has an origin in truth than there must have been some strange people walking around back then. The author, when not utilizing source material, relies on ambiguous terminology such as "evidence suggests..." without presenting evidence. This particular reference is to Celtic expeditions in the Mississippi valley. There are startling claims, including that the expeditions extended all the way into Kentucky. The evidence presented for such a claim is a single sentence about "Ogam inscriptions" being found in Arkansas. It seems the author wanted to remove credit for cultural advancements, such as Mongolian mastery of horse riding, and give it to Western Europeans. It is interesting enough that there are out of place mummies in China and Mongolia and other places. We don't have to usurp the ancient natives of their achievements as a result.
As I said, it may seem like I didn't like the book, which is not true. I do think the new material presented will be interesting to most fans of the genre. Though I don't agree with the author's conclusions I enjoyed reading them.
