"Our forebears, finding large, incomprehensible earthworks scattered down the Mississippi Valley, refused to believe they were built by the aborigines who still cluttered up the place and impeded settlement.
Mr Silverberg describes, with gleeful and copious quotation, the nineteenth-century literature of speculation which attributed these monuments to Phoenicians, stray Vikings, the Lost Tribes of Israel, refugees from Atlantis, an extinct race of giants, and Welshmen.
The book, which is charmingly written, ends with a history of the archaeological works which gave the mounds back t the Indiana."
