When I originally bought the book a few years ago it was a much briefer version, so I can not comment on what it is now like as it appears to more detailed.
Authors review of The World Axis as an Atmospheric Phenomenon
the mythological phenomenon loosely identified as the axis mundi dates back to the earliest stages of civilisation and is described by the most diverse cultures in remarkably similar terms. It can be explained by reference to a once visible entity in the sky, with a complex, evolving morphology and a possible link to the zenith or the pole. The prototype may have been the zodiacal light or, as recent insights in plasma physics indicate, an enhanced aurora formed in prehistoric times.
