One of the reasons for me choosing

The Holy Grail of Roof Framing Geometry and Trigonometry

 for the title of my book.

Research on my mother’s maiden name of St. Clair.

Rosslyn Chapel was a rebuilding of the Temple of Solomon, designed by St. Clair

Research shows that ras or ros means wisdom. As such, could it be that the term ‘roslin’ means the St. Clairs , who were also the guardians of the fountain of wisdom pertaining specifically to the Holy Blood, the Holy Grail and the Holy Light.

  1. Hey Sim,
    Is this book going to be for sale in the near future?

  2. Luke, no it will not be in the near future. Maybe late next year.

  3. Sorry for the late response for this I totally missed your reply- very interested in purchasing it when it's available! Thanks a lot sim
