I really love history and I really love historical mysteries. However, it is difficult to find a good book on the subject that is not simply a platform for expressing its author's support for the ridiculous "theories" of people like Erich Van Daniken, Charles Hapgood, or Gavin Menzies. Imagined how pleased I was to discover this volume, and its companion, "History's Mysteries". Haughton writes about fascinating historical questions such as "Who built Great Zimbabwe?" or "Is the Round Tower of Providence, RI evidence for pre-Columbian European voyages to North America?". He writes about these questions without resorting to tales of ancient alien visitations, lost continents (though he does discuss beliefs about Atlantis, Lemuria, and Mu), or ancient technologically-advanced civilizations. Haughton examines the history of these controversies, various theories that have been advanced to explain them, and where opinions now stand on them. Some of these "mysteries" were the products of racism or exaggeration (i.e. the theory that a lost, possibly European or Asian, civilization built the mounds visible today in the Midwestern and Southern US; actually, they were built by Native Americans), others have been largely solved (the supposed historical/spiritual significance of Renne-le-Chateau in France was the product of a hoax), while others remain mysterious (Who were the "Green Children" allegedly found near the English village of Woolpit in the 12th century?)Haughton writes rationally about all of them, providing a wealth of fascinating information while avoiding the stridency so often associated with writing on these subjects. Highly recommended.
