HOLY BLOOD, HOLY GRAIL-Fact or Fiction? The book Holy Blood, Holy Grail, by Michael Baigent, et al., is anything but “accurate-free from error, conforming exactly to truth…restricted to or based upon fact” If it were not for the real people and real places interwoven within the fallacies, the HBHG book would have failed to qualify as “nonfiction,” even under the very liberal literary definition of the term. As Prof. Onapolous demonstrates in this long overdue analysis of the HBHG, virtually none of the HBHG authors’ claims, hypotheses, or conclusions are supported by historical fact. Prof. Onapolous reveals that the primary source of the “documents” relied upon by the HBHG authors was no other than Pierre Plantard. In 1993, Pierre Plantard admitted in a French court of law to having orchestrated the fabrication of the documents relied upon by the HBHG authors as part of an elaborate fraud.
