Even though our research may have uncovered what an early people knew, without an eyewitness description or a written record at hand we can never really be sure how they came to know it. What the stimulus or motivation or acci- dental discovery may have been that led to such and such an idea or to this or that custom or practice, we oftentimes can only speculate. And, in so doing, one is obliged to seek the most conservative and credible solu- tion possible, while at the same time realizing that the true explanations for some human thoughts and/or actions may well border on the bizarre and irrational. This book, then, is both fact and fiction. In it, I not only recount what I and other researchers have learned through the decades about the pre-Columbian peoples of Mesoamerica and their impressive cultural achievements, but I also attempt to posit what I hope are ratio- nal hypotheses concerning where, when, and how many of their innova- tive breakthroughs and discoveries were actually made. Thus, while most of the facts I present are immutable, some of my interpretations and ex- planations are admittedly conjectural, and the reader is invited to decide for himself or herself whether more credible answers yet can be given. This, then, is really an invitation to join me in solving not one but a whole series of mysteries. As we go along, I will tell you what the clues are, and give you my best arguments for what the “motives” may have been. Hopefully, by the time my case has been made, you — the jury — will have been convinced beyond a reasonable doubt, and can render an impartial verdict, namely that the pre-Columbian peoples of Mesoamer- ica were among the most precocious and ingenious of any on our planet! Among my companions on this quest into the origins of the Meso- american intellect have been half a generation of field assistants drawn chiefly from my students at Middlebury and Dartmouth Colleges. To each and all of them I owe a special debt of thanks for their patience, un- derstanding, and unflagging good spirit under what have oftentimes been trying and difficult conditions. Beginning with Aaron Kiley, they include Linc Cleveland, Rob Walkinshaw, Karin Malmström, Bruce Keogh, Jay Harter, Paul Dunn, Warren Whitney, Juan Carlos Navarro, xi 00-T5327-FM 5/18/2001 12:55 PM Page xii Cycles of the Sun, Mysteries of the Moon and Alex de Sherbinin. Though the questions of some of the 100-odd students who took part in my Foreign Study courses in Mexico through the years helped to guide my own thoughts into new directions, I must make special mention of at least one, Sarah Kotchian, whose indepen- dent research project led to the accidental discovery of what was then probably the oldest magnetic artifact in the world. (Four years later, Paul Dunn became the first person to recognize the magnetic properties of the yet-older “Fat Boys.”) On some of my later Foreign Study Programs, when I chose not to both drive and lecture at the same time, I depended on the iron nerves and steady hands of such stalwart chauffeurs as John Corbett, Steve Mines, and Tony Hartshorn; to all three of them I say “thanks again” for bringing all my student charges and me home again in one piece.
