Over the years there have been several books written about Rosslyn Chapel, the most recent seem determined to undermine any possibility that this very special building is anything more than a stone church, albeit highly detailed and elaborate, and nothing more. This work confronts this rationalist stance head on and presents startling new evidence suggesting just the opposite. From the outset it should be clear that two quite distinct histories are applied to Rosslyn Chapel. One is the official version insisting that the Chapel is nothing more than a place of simple piety and worship, while the other is a much more esoteric shadow interpretation with immense implications, the histories are not interchangeable and there are very few points of convergence.
