I suppose it is natural for a member of the vast right wing conspiracy such as myself to love all manner of conspiracy theories, esoteric knowlege, and cyyptography. Dan Brown's page turner has pulled me into his strange world. Although a work of fiction, he swears that the essential elements of the tale, the Priory of Sion, the symbolism Da Vinci painted in The Last Supper, The Mona Lisa, and other works, and much more, is all true. Fascinating stuff you do not have to swallow whole to thoroughly be entertained by. Heretical? I'd write more, but I must get back to the book. It has kept me up very late on a couple of days that were already too long. Highly recommended.
