लेखक: John Ritchie

Alan Butler has spent 30 years immersed in world history, writing books delving into neglected recesses of the past. Butler is an expert in ancient astronomy and astrology and proficient in interpreting historical symbolism of the sort represented by Rosslyn Chapel. John Ritchie has travelled the world as film cameraman and a stills photographer. These days he is a broadcaster and a successful historian. He brings to this book his keen eye, a peerless knowledge of Scottish history and a trust on the part of its custodians that have given Butler and Ritchie unrivalled access to Rosslyn Chapel.
