The Maya were in possession of a complex and extremely accurate calendar. We are now able to decode at least some of their hieroglyphs, many of which turn out to be dates. What was of the greatest concern to the Maya was the sun and their belief in an apocalyptic future for humanity. It is easy to dismiss their concerns as simple superstitions, but what if (as Cotterell's work would seem to suggest) they knew more about this subject than we do? We owe it both to ourselves and our children to do the best we can to resurrect the knowledge. At least then we may be prepared for global changes even if we cannot control them. This surely must be the responsible attitude of all true scientists, and I for one--though I take no credit for Maurice Cotterell's discoveries--want to know. We can but trust that you, the reader, feel the same way. -- Adrian Gilbert
