Loki, I never mentioned the "Underground Stream", that was Franklin.
I mention that the PRIOTY OF SION was first mentioned in 1956, when Pierre Plantard planted those fabricated documents in France's Bibliotheque Nationale so he could claim Merovingian descent.
Without mentioning Baigent and Leigh by name as "respected Templar historians", you alluded that Lincoln was, and much of the information about the Priory connected to the Templars, the Cathars, Sangreal, Rennes le Chateau, Poussin's "Et in Arcadia Ego, Teniers, etc, obviously come from their book and probably from Picknett and Prince, and Sinclair, and NOT from the authors you mentioned, nor from Dr Lord.
If you have documented evidence outside of these pop pseudo history books, please bring it forth.
While I did state that Reed, Addison, and Haag were NOT professional "Well respected historians", just mere authors of a few books on historical subjects, I NEVER "dissed", as you claim, Dr Evelyn Lord, who is the only real lettered academic that you have mention as a source, which you seem to include as a way of adding gravitas to the above authors.
